  • Mechanize Javascript ...

    - by Horace Ho
    I try to submit a form by Mechanize, however, I am not sure how to add necessary form valuables which are done by some Javascript. Since Mechanize does not support Javascript yet, and so I try to add the variables manually. The form source: <form name="aspnetForm" method="post" action="list.aspx" language="javascript" onkeypress="javascript:return WebForm_FireDefaultButton(event, '_ctl0_ContentPlaceHolder1_cmdSearch')" id="aspnetForm"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/..." /> <script type="text/javascript"> <!-- var theForm = document.forms['aspnetForm']; if (!theForm) { theForm = document.aspnetForm; } function __doPostBack(eventTarget, eventArgument) { if (!theForm.onsubmit || (theForm.onsubmit() != false)) { theForm.__EVENTTARGET.value = eventTarget; theForm.__EVENTARGUMENT.value = eventArgument; theForm.submit(); } } // --> </script> <script language="javascript"> <!-- var _linkpostbackhit = 0; function _linkedClicked(id, key, str, a, b) { if (!b || !_linkpostbackhit) { if (!a) { __doPostBack(key, id); _linkpostbackhit = 1; } else { if (window.confirm(str)) { __doPostBack(key, id); _linkpostbackhit = 1; } } } return void(0); } // --> </script> ... <a href="JavaScript:_linkedClicked('123456','_ctl0:ContentPlaceHolder1:Link', '',0,1);">123456</a> ... </form> I tried to add the 2 variables: page.forms.first['__EVENTTARGET'] = '_ctl0:ContentPlaceHolder1:Link' page.forms.first['__EVENTARUGMENT'] = '123456' and submit the form: page.forms.first.click_button(page.forms.first.buttons.first) The result returned only (re)show the current list of links as if I have not clicked on any of the links. Any help will be appreciated. Thanks!

  • Install Trac on 64bits Windows 7

    - by Tufo
    I'm configuring a new Developing Server that came with Windows 7 64bits. It must have installed Trac with Subversion integration. I install Subversion with VisualSVN 2.1.1, clients with TortoiseSVN 1.6.7 and AnkhSVN 2.1.7 for Visual Studio 2008 SP1 integration. All works fine! my problem begun when going to Trac installation. I install python 2.6 all fine. Trac hasn't a x64 windows installer, so I installed it manually by compiling it with python console (C:\Python26\python.exe C:/TRAC/setup.py install). After that, I can create TRAC projects normally, the Trac core is working fine. And so the problem begins, lets take a look at the Trac INSTALL file: Requirements To install Trac, the following software packages must be installed: Python, version = 2.3. Subversion, version = 1.0. (= 1.1.xrecommended) Subversion SWIG Python bindings (not PySVN). PySQLite,version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x) Clearsilver, version = 0.9.3 (0.9.14 recommended) Python: OK Subverion: OK Subversion SWIG Python bindings (not PySVN): Here I face the first issue, he asks me for 'cd' to the swig directory and run the 'configure' file, and the result is: C:\swigwin-1.3.40> c:\python26\python.exe configure File "configure", line 16 DUALCASE=1; export DUALCASE # for MKS sh ^ SyntaxError: invalid syntax PySQLite, version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x): Don't need, as Python 2.6 comes with SQLLite Clearsilver, version = 0.9.3 (0.9.14 recommended): Second issue, Clearsilver only has 32bit installer wich does not recognize python installation (as registry keys are in different places from 32 to 64 bits). So I try to manually install it with python console. It returns me a error of the same kind as SWIG: C:\clearsilver-0.10.5>C:\python26\python.exe ./configure File "./configure", line 13 if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then ^ SyntaxError: invalid syntax When I simulate a web server using the "TRACD" command, it runs fine when I disable svn support but when I try to open the web page it shows me a error regarding ClearSilver is not installed for generating the html content. AND (for making me more happy) This TRAC will run over IIS7, I mustn't install Apache... I'm nearly crazy with this issue... HELP!!!

  • Which StackOverflow-style MarkDown (WMD) javascript editor should I use?

    - by Edan Maor
    Background I'm working on an application which requires user-entered content, and I've decided to use a StackOverflow-style MarkDown editor. After researching this topic for the last few days, I realize there are numerous forks of the base WMD editor, some with a few basic enhancements and some with serious differences from the StackOverflow one. Since this will be the heart of the application, I'd like to start with the best code base I can. I'd be happy if anyone can recommend which one of the many solutions out there best fits my needs. Below is requirements, plus what I've managed to find already. I'm hoping this question will help me decide which version to go with, and maybe help me discover a port out there that's an even better fit for my needs. The requirements for my project Live Preview Multiple editors on the same page (not know how many in advance, since the user can dynamically add another editing box). Ability to extend with extra buttons (I'd like a button to upload a picture, instead of just adding an img url). Ability to dynamically show/hide the edit box (and only see the preview box). Not an absolute must, but I'd prefer to stick as close to StackOverflow's look and feel, since it's well known. Don't know if this matters, but the backend is written in Django. Editors I've looked at Here are a few of the code bases I've looked at, with thoughts. Obviously, I might be missing another solution out there. The derobins version. From what I can tell, this is the official StackOverflow version. Seems like it doesn't support multiple editors on one page. JQuery.MarkEdit. Looks very good, but is pretty different from the StackOverflow version. MooWMD. Looks like the winner right now, but I'm a little concerned since it looks less active/hackable than MarkEdit. The wmd-new version. Not sure, looks like an old codebase without much use. The SocialSite branch. Seems like it's not for public use.

  • Which third party website thumbnailing services do you use?

    - by Ben Delarre
    I've got a requirement for showing thumbnails of arbitrary websites. I need to be able to show small thumbnails (120px by 90px), and larger thumbnails of around 480px wide. I'll need to specify the queue and invalid placeholder images and preferably have a pingback when the queued images are processed so I can respond appropriately. I'd also need a simple API I can use either directly embedded in my HTML, or from a simple web request to queue the images. I've been looking at various services ranging from low-fi services, to large scale ones - here's some examples: www.bitpixels.com Uses Google AppEngine, seems like a prototype or a toy. Free! www.websnapr.com Tried using this, made a free account and requested a thumbnail. Waited a few minutes and refreshed a couple of times, and ended up having the account banned. Free is tricky yes, but if I can't try it out successfully I'm disinclined to pay. www.shrinktheweb.com Free account seems to be very quick. Lots of documentation on the site, and even covers local caching of the images to your own server (documentation mostly in PHP). Quality of thumbnails look good, and there appear to be sufficient options for setting thumbnail placeholder images and parameters for altering how the thumbnailing is done. Also supports large 'screenshots' of URLs - very useful for me. Discovered the PRO pricing is an à la carte menu, allowing me to select just the features I want and keep the monthly cost low. Excellent stuff, have decided to use this service. www.thumbalizr.com Good coverage of thumbnail sizes and control options - even allowing specification for browser width when thumbnailing. No ping-back, but I can live without that. Supports local caching of images with PHP API, would prefer .NET, but can port it if necessary. Looks like a fairly professional service but seems fairly expensive for the number of thumbnails you get to generate. apologies for lack of proper linking - spam protection! I'm not entirely convinced by any of them, and since this will be a long term service I'd like some stability and support. I'm willing to pay for the service, but I'd want something that fulfills most if not all of my requirements for that. I should also mention that we're hosted on Windows under IIS, so local solutions involving Xvfb and the like sadly can't be used for this project. So my question is: what services do you use? How have they panned out, are you happy with them?

  • How do I reward my developers for the little things they get right?

    - by Nat
    I am in a tech lead role and my developers get stuff right most of the time. How do I communicate to them thier value to me? (I.e. they have value because I do not have to go through and point out mistakes which means I do not have to watch them like a hawk which frees me to do more useful things). In summary For doing the mundane well on a day to day basis, it is good to recognise the developers effort verbally to them. An honest thankyou that mentions the specific behaviour and its positive repercussions to you personally will be well received, adjust the language to suite each individual. (Note that other developers within earshot may also respond to this by increasing their efforts in this specific activity.) Other things that should be done regularly are: Team drinks In many cultures this is an entirely worthy way of giving the team some time to socialise and relax. Be sure that you do not exclude people who do not drink or are not keen on pub culture. Shared meals are another option. Formal written (email) acknowledgment and praise to senior managers of the teams efforts and successes. (Note that acknowledging individuals alone may damage team spirit) Work the hours you expect your team to do. If they absolutely must work late for a deadline, be there in support Go to bat for the team. Refuse to let them be forced to work long periods of overtime without compensation. Protect them from level politics and stress. Give your team the best equipment you can afford. Good tools show respect and improve productivity. Small or large team rewards where appropriate can consist of many interesting activities/ items. If it allows the team to get together in a fun and even lightly competitive manner it will work (foosball table, go-karting, darts board, video game console etc). Don’t forget to listen to what the team wants, each team will have different ideas. Ensure they are getting a fair deal financially from the company. While different people may have different expectations of their pay, someone being paid unfairly will rot morale for the entire team

  • Datagrid using usercontrol

    - by klawusel
    Hello I am fighting with this problem: I have a usercontrol which contains a textbox and a button (the button calls some functions to set the textbox's text), here is the xaml: <UserControl x:Class="UcSelect" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Control1Name" <Grid x:Name="grid1" MaxHeight="25"> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="25"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="25"/> </Grid.RowDefinitions> <TextBox x:Name="txSelect" Text="{Binding UcText, Mode=TwoWay}" /> <Button x:Name="pbSelect" Background="Red" Grid.Column="1" Click="pbSelect_Click">...</Button> </Grid> And here the code behind: Partial Public Class UcSelect Private Shared Sub textChangedCallBack(ByVal [property] As DependencyObject, ByVal args As DependencyPropertyChangedEventArgs) Dim UcSelectBox As UcSelect = DirectCast([property], UcSelect) End Sub Public Property UcText() As String Get Return GetValue(UcTextProperty) End Get Set(ByVal value As String) SetValue(UcTextProperty, value) End Set End Property Public Shared ReadOnly UcTextProperty As DependencyProperty = _ DependencyProperty.Register("UcText", _ GetType(String), GetType(UcSelect), _ New FrameworkPropertyMetadata(String.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, New PropertyChangedCallback(AddressOf textChangedCallBack))) Public Sub New() InitializeComponent() grid1.DataContext = Me End Sub Private Sub pbSelect_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 'just demo UcText = UcText + "!" End Sub End Class The UserControl works fine when used as a single control in this way: <local:UcSelect Grid.Row="1" x:Name="ucSingle1" UcText="{Binding FirstName, Mode=TwoWay}"/> Now I wanted to use the control in a custom datagrid column. As I like to have binding support I choosed to derive from DataGridtextColumn instead of using a DataGridTemplateColumn, here is the derived column class: Public Class DerivedColumn Inherits DataGridTextColumn Protected Overloads Overrides Function GenerateElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oElement = MyBase.GenerateElement(oCell, oDataItem) Return oElement End Function Protected Overloads Overrides Function GenerateEditingElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oUc As New UcSelect Dim oBinding As Binding = CType(Me.Binding, Binding) oUc.SetBinding(UcSelect.UcTextProperty, oBinding) Return oUc End Function End Class The column is used in xaml in the following way: <local:DerivedColumn Header="Usercontrol" Binding="{Binding FirstName, Mode=TwoWay}"></local:DerivedColumn> If I start my program all seems to be fine, but changes I make in the custom column are not reflected in the object (property "FirstName"), the changes are simply rolled back when leaving the cell. I think there must be something wrong with my GenerateEditingElement code, but have no idea ... Any Help would really be appreciated Regards Klaus

    Im fairly new to jquery and Im using jquery tools for tabs. I am wanting in one of the tabs to show flexigrid, but when I try to do this flexigrid does not show up, its just blank. If I setup flexigrid in a stand alone page outside the tab it works just fine. Below is the code that isnt working. Again Im new so please go easy! <ul class="css-tabs"> <li><a href="#details">Account Details</a></li> <li><a href="#accounts">Sub Accounts</a></li> <li><a href="#groups">Groups</a></li> <li><a href="#support">Tickets</a></li> </ul> <div class="css-panes"> <div>Tab 1</div> <div><table id="flex1" style="display:none"></table></div> <div>Tab 3</div> <div>Tab 4</div> </div> <script> $(function() { $("ul.css-tabs").tabs("div.css-panes > div").history(); }); $('.flexme1').flexigrid(); $('.flexme2').flexigrid({height:'auto',striped:false}); $("#flex1").flexigrid ( { url: '/accounts_list.php', dataType: 'json', colModel : [ {display: 'ID', name : 'id', width : 45, sortable : true, align: 'center'}, {display: 'Username', name : 'username', width : 120, sortable : true, align: 'left'}, {display: 'Display Name', name : 'displayname', width : 150, sortable : true, align: 'left'}, {display: 'Limit', name : 'accounts', width : 50, sortable : true, align: 'center'}, {display: 'Rate', name : 'charge', width : 50, sortable : true, align: 'center'}, {display: 'Subs', name : 'subcount', width : 50, sortable : true, align: 'center'} ], searchitems : [ {display: 'ID', name : 'id'}, {display: 'Username', name : 'username', isdefault: true}, {display: 'Display Name', name : 'displayname'} ], sortname: "id", sortorder: "desc", usepager: true, singleSelect: true, title: 'Test', useRp: true, rp: 20, showTableToggleBtn: false, width: 500, height: 250 }); </script>

  • WPF / Silverlight Binding when setting DataTemplate programically

    - by Daniel
    I have my little designer tool (my program). On the left side I have TreeView and on the right site I have Accordion. When I select a node I want to dynamically build Accordion Items based on Properties from DataContext of selected node. Selecting nodes works fine, and when I use this sample code for testing it works also. XAML code: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> <layoutToolkit:AccordionItem Header="Controller Info"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </layoutToolkit:AccordionItem> </layoutToolkit:Accordion> C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; //e.NewValue is a class that contains Name property } } } But the problem occurs when I'm trying to achive this using DateTemplate and dynamically build AccordingItem, the Binding is not working: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous" /> and DataTemplate in my ResourceDictionary <DataTemplate x:Key="dtSceneNodeContent"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </DataTemplate> and C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { ResourceDictionary rd = new ResourceDictionary(); rd.Source = new Uri("/SilverGL.GUI;component/SilverGLDesignerResourceDictionary.xaml", UriKind.RelativeOrAbsolute); if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; AccordionItem accController = new AccordionItem(); accController.Header = "Controller Info"; accController.ContentTemplate = rd["dtSceneNodeContent"] as DataTemplate; accPanel.Items.Add(accController); } else { // Other type of node } } } I really need help with this issue. Thanks for any support.

  • UIViewController not oreintating. Methods not called

    - by capple
    Greetings, This question does seem to be an ongoing saga in the world of iphone SDK... so heres my contribution... Had two separate projects from the same template... one semi-works, the other not at all... Please let me explain my steps... used this basic GL ES template //iphonedevelopment.blogspot.com/2008/12/opengl-project-template-for-xcode.html had to sort out some of the 'Release' configuration but otherwises has eveything I need to add orientation to a GL ES project. One my first project, did my stuff, then added these methods.... -(BOOL)shouldAutoRotateToInterfaceOrientation ..... -(void)willRotateToInterfaceOrientation .... -(void)didRotateFromInterfaceOrientation .... -(void)willAnimateRotationToInterfaceOrientation .... And understand what they do (or are trying to do in my case), the (BOOL)should... gets called once when the view controller is created, and returns 'YES'. But after that none of the other methods are called! So I started from scratch with a blank template (GL ES one from above)...and added minimum to support auto rotation. But this time none of the methods get called! So I investigated .... //developer.apple.com/iphone/library/qa/qa2010/qa1688.html as it said, I added the GLViewController.view first, then added the GLview as subviews of the application delegate. Nothing! Then found this //www.iphonedevsdk.com/forum/iphone-sdk-development/44993-how-determine-ipad-launch-orientation.html which states to enable orientation notifications [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and then subsequently disable them in the view controller... makes sense...did it, nothing... I think the notifications might be on by default though, since I didn't need to enable them in the first project, yet it still try to verify a orientation (i.e (BOOL)shouldAutoRotate... )... If any one could help me out it would be greatly appreciated as this issue is driving me insane. Thanks in advance. The code can be found here ... http://rapidshare.com/files/392053688/autoRotation.zip N.B These projects avoid nib/xib resources, would like to keep it that way if possible. P.S iPad device not out where I am so I cannot test on a device yet. Would be nice for it to work on the simulator.

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.

  • Odd "Object reference not set to an instance of an object" involving xWinForms

    - by Kyle
    Hey, I've been trying to get the xWinForms 3.0 library (a library with forms support in xna) working with my C# XNA Game project but I keep getting the same problem. I add the reference to my project, put in the using statement, declare a formCollection variable and then I try to initialize it. whenever I run the project I get stopped on this line: formCollection = new FormCollection(this.Window, Services, ref graphics); it gives me the error: " System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object."

  • redoing object model construction to fit with asynchronous data fetching

    - by Andrew Patterson
    I have a modeled a set of objects that correspond with some real world concepts. TradeDrug, GenericDrug, TradePackage, DrugForm Underlying the simple object model I am trying to provide is a complex medical terminology that uses numeric codes to represent relationships and concepts, all accessible via a REST service - I am trying to hide away some of that complexity with an object wrapper. To give a concrete example I can call TradeDrug d = Searcher.FindTradeDrug("Zoloft") or TradeDrug d = new TradeDrug(34) where 34 might be the code for Zoloft. This will consult a remote server to find out some details about Zoloft. I might then call GenericDrug generic = d.EquivalentGeneric() System.Out.WriteLine(generic.ActiveIngredient().Name) in order to get back the generic drug sertraline as an object (again via a background REST call to the remote server that has all these drug details), and then perhaps find its ingredient. This model works fine and is being used in some applications that involve data processing. Recently however I wanted to do a silverlight application that used and displayed these objects. The silverlight environment only allows asynchronous REST/web service calls. I have no problems with how to make the asychhronous calls - but I am having trouble with what the design should be for my object construction. Currently the constructors for my objects do some REST calls sychronously. public TradeDrug(int code) { form = restclient.FetchForm(code) name = restclient.FetchName(code) etc.. } If I have to use async 'events' or 'actions' in order to use the Silverlight web client (I know silverlight can be forced to be a synchronous client but I am interested in asychronous approaches), does anyone have an guidance or best practice for how to structure my objects. I can pass in an action callback to the constructor public TradeDrug(int code, Action<TradeDrug> constructCompleted) { } but this then allows the user to have a TradeDrug object instance before what I want to construct is actually finished. It also doesn't support an 'event' async pattern because the object doesn't exist to add the event to until it is constructed. Extending that approach might be a factory object that itself has an asynchronous interface to objects factory.GetTradeDrugAsync(code, completedaction) or with a GetTradeDrugCompleted event? Does anyone have any recommendations?

  • Rails scalar query

    - by Craig
    I need to display a UI element (e.g. a star or checkmark) for employees that are 'favorites' of the current user (another employee). The Employee model has the following relationship defined to support this: has_and_belongs_to_many :favorites, :class_name => "Employee", :join_table => "favorites", :association_foreign_key => "favorite_id", :foreign_key => "employee_id" The favorites has two fields: employee_id, favorite_id. If I were to write SQL, the following query would give me the results that I want: SELECT id, account, IF( ( SELECT favorite_id FROM favorites WHERE favorite_id=p.id AND employee_id = ? ) IS NULL, FALSE, TRUE) isFavorite FROM employees Where the '?' would be replaced by the session[:user_id]. How do I represent the isFavorite scalar query in Rails? Another approach would use a query like this: SELECT id, account, IF(favorite_id IS NULL, FALSE, TRUE) isFavorite FROM employees e LEFT OUTER JOIN favorites f ON e.id=f.favorite_id AND employee_id = ? Again, the '?' is replaced by the session[:user_id] value. I've had some success writing this in Rails: ee=Employee.find(:all, :joins=>"LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=1", :select=>"employees.*,favorites.favorite_id") Unfortunately, when I try to make this query 'dynamic' by replacing the '1' with a '?', I get errors. ee=Employee.find(:all, :joins=>["LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=?",1], :select=>"employees.*,favorites.favorite_id") Obviously, I have the syntax wrong, but can :joins expressions be 'dynamic'? Is this a case for a Lambda expression? I do hope to add other filters to this query and use it with will_paginate and acts_as_taggable_on, if that makes a difference. edit errors from trying to make :joins dynamic: ActiveRecord::ConfigurationError: Association named 'LEFT OUTER JOIN favorites ON employees.id=favorites.favorite_id AND favorites.employee_id=?' was not found; perhaps you misspelled it? from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1906:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1911:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1910:in `each' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1910:in `build' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/associations.rb:1830:in `initialize' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1789:in `new' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1789:in `add_joins!' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1686:in `construct_finder_sql' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1548:in `find_every' from /Users/craibuc/.gem/ruby/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:615:in `find'

  • Suggestions for designing large-scale Java webapp from the group up

    - by Chris Thompson
    Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring. The problem is most of my webapps have been thrown together just to be a proof of concept and what I'm struggling with is what set of frameworks to use. I need to have both a browser based application as well as a web service designed to support access from mobile devices (Android and iPhone for now). Ideally, I'd like to design this system in such a way that I don't end up rewriting all of my servlets for each client (browser and phone) although I don't mind having some small checks in there to properly format the data. In addition, although I'm the only developer now, that won't necessarily be the case down the road and I'd like to design something that scales well both with regards to traffic and number of developers (isn't just a nightmare to maintain). So where I am now is planning on using GWT to design the browser-based interface but I'm struggling with how to reuse that code with to present the interface (most likely xml) for the mobile devices. Using GWT RPC would, I think, make it relatively easy to do all of the AJAX in the browser, but might make generating xml for the mobile phones difficult. In addition, I like the idea of using something like Hibernate for persistence and Spring Security to secure the whole thing. Again, I'm not sure how well those will cooperate with GWT (I think Hibernate should be fine...) There's obviously a lot more to this than I've presented here, but I've tried to give you the 5-minute overview. I'm a bit stumped and was wondering if anybody in the community had any experience starting from this place. Does what I'm trying to do make sense? Is it realistic? I have no doubt I can make all of these frameworks speak the same language, I'm just wondering if it's worth my time to fight with them. Also, am I missing a framework that would be really beneficial? Thanks in advance and sorry for the relatively broad question... Chris

  • Exporting a report from Crystal 8.5 causes the report to first refresh, then export, with unexpected

    - by LittleBobbyTables
    We have a VB6 application that can generate reports using the Crystal Reports 8.5 runtime. To generate one of the more complicated reports we have, the VB app does the following: Deletes records from a SQL table (we'll call it Foo) based on the session ID of the user Performs a select statement, and populates the Foo table with the contents of the select statement. Massages the data in Foo. Executes the report (we'll call it Bar). The Bar report uses the Foo table as part of some outer joins to get some descriptions. After the report is opened and populated, the code then deletes the records in Foo. If you ever look in Foo there will be no data since it is always purged at the end, but the Crystal Report will still have the data, since Foo wasn't cleared out until after the report ran. Most sites can export this report afterwards, to either PDF or Excel, with no issue. One site, however, has two servers in production where if you attempt to export the Bar report (doesn't matter what format it is exported to), the report will visibly refresh and then export the report in the requested format. This refresh, however, causes the exported data to be invalid because the report is still doing the outer joins to the Foo table, which is now empty. I'm at a total loss why the report refreshes before printing on these two servers. One server has Crystal Reports 8.5 installed on it as well as the Crystal Reports 8.5 runtime (so they can modify reports). The other server only has the Crystal Reports 8.5 runtime (so you can generate reports from the VB application, but can't modify them on that server). Both of the servers belong to a French site. Another support staff here said the issue sounded vaguely familiar to an issue a few years ago, and suggested re-registering DLLs. I have tried unregistering and re-registering the following DLLs out of frustration: Crystl32.ocx crxlat32.dll cpeau32.dll exportmodeller.dll crtslv.dll atl.dll Unregistering and re-registering the above DLLs does not fix the issue. If we take the problem report, and run it on any of our development or QA servers, we have no issues; the report does NOT refresh before exporting, and the data looks consistent. It seems like a server or regional setting may be causing this, but what could possibly cause the report to refresh before exporting on only two of our servers? The most obvious solution is to simply alter the code so the Foo table isn't purged after the report is run, only when the report is run, but this is a production issue, the customer wants a fix now, and there's quite a few hoops to jump through to make the change.

  • CSS selectors : should I make my CSS easier to read or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It make my .css file harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • Amusing or Sad? Network Solutions

    - by dbasnett
    When I got sick my email ended up in every drug sellers email list. Some days I get over 200 emails selling everything from Viagra to Xanax. Either they don't know what my condition is or they are telling me you are a goner, might as well chill-ax and have a good time. In order to cut down on the mail being downloaded I thought I would add all of the Junk email senders from Outlook to my Network Solution mail server. Much to my amazement I could not find that import Spammers button, so I submitted a tech support request. Here is the response: Thank you for contacting Network Solutions Customer Service Department. We are committed to creating the best Customer experience possible. One of the first ways we can demonstrate our commitment to this goal is to quickly and efficiently handle your recent request. We apologize for any inconvenience this might have caused you. With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers. An alternative option is for you to create a Custom Filter that filters unwanted e-mails. To create a Custom Filter: Open a Web browser (e.g., Netscape, Microsoft Internet Explorer, etc.). Type mail.[domain name].[ext] in the address line. Login to your Network Solutions email account. Click on the Configuration left menu tab. Click on the Custom Filter link. Type the rule name. blah, blah, blah Basically add them one at a time. "We are committed to creating the best Customer experience possible." No you are not. You are trying to squeeze every nickle you can out of me. "With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers." Maybe I should apply for a job to write those ten complicated lines of code... Maybe I should question my choice of vendors, because if they truly "cannot" then they are to stupid to have my business. It is both amusing and sad. I'll be posting this in every forum I am a member of.

  • Ultimate Get/Post with Android Thread for Dummies

    - by Jayomat
    Hi, I'm writing an app to check for the bus timetable's. Therefor I need to post some data to a html page, submit it, and parse the resulting page with htmlparser. Though it may be asked a lot, can some one help me identify if 1) this page does support post/get (I think it does) 2) which fields I need to use? 3) How to make the actual request? this is my code so far: String url = "http://busspur02.aseag.de/bs.exe?Cmd=RV&Karten=true&DatumT=30&DatumM=4&DatumJ=2010&ZeitH=&ZeitM=&Suchen=%28S%29uchen&GT0=&HT0=&GT1=&HT1="; String charset = "CP1252"; System.out.println("startFrom: "+start_from); System.out.println("goTo: "+destination); //String tag.v List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("HTO", start_from)); params.add(new BasicNameValuePair("HT1", destination)); params.add(new BasicNameValuePair("GTO", "Aachen")); params.add(new BasicNameValuePair("GT1", "Aachen")); params.add(new BasicNameValuePair("DatumT", day)); params.add(new BasicNameValuePair("DatumM", month)); params.add(new BasicNameValuePair("DatumJ", year)); params.add(new BasicNameValuePair("ZeitH", hour)); params.add(new BasicNameValuePair("ZeitM", min)); UrlEncodedFormEntity query = new UrlEncodedFormEntity(params, charset); HttpPost post = new HttpPost(url); post.setEntity(query); InputStream response = new DefaultHttpClient().execute(post).getEntity().getContent(); // Now do your thing with the facebook response. String source = readText(response,"CP1252"); Log.d(TAG_AVV,response.toString()); System.out.println("STREAM "+source); One person also gave me a hint to use firebug to read what's going on at the page, but I don't really understand what to look for, or more precisely, how to use the provided information. I also find it confusing, for example, that when I enter the data by hand, the url says, for example, "....HTO=Kaiserplatz&...", but in Firebug, the same Kaiserplatz is connected to a different field, in this case: \<\td class="Start3" Kaiserplatz <\/td (I inserted \ to make it visible) The last line in my code prints the html page, but without having send a request.. it's printed as if there was no input at all... My app is almost done, I hope someone can help me out to finish it! thanks in advance

  • What is the best python module skeleton code?

    - by user213060
    == Subjective Question Warning == Looking for well supported opinions or supporting evidence. Let us assume that skeleton code can be good. If you disagree with the very concept of module skeleton code then fine, but please refrain from repeating that opinion here. Many python IDE's will start you with a template like: print 'hello world' That's not enough... So here's my skeleton code to get this question started: My Module Skeleton, Short Version: #!/usr/bin/env python """ Module Docstring """ # ## Code goes here. # def test(): """Testing Docstring""" pass if __name__=='__main__': test() and, My Module Skeleton, Long Version: #!/usr/bin/env python # -*- coding: ascii -*- """ Module Docstring Docstrings: http://www.python.org/dev/peps/pep-0257/ """ __author__ = 'Joe Author ([email protected])' __copyright__ = 'Copyright (c) 2009-2010 Joe Author' __license__ = 'New-style BSD' __vcs_id__ = '$Id$' __version__ = '1.2.3' #Versioning: http://www.python.org/dev/peps/pep-0386/ # ## Code goes here. # def test(): """ Testing Docstring""" pass if __name__=='__main__': test() Notes: """ ===MODULE TYPE=== Since the vast majority of my modules are "library" types, I have constructed this example skeleton as such. For modules that act as the main entry for running the full application, you would make changes such as running a main() function instead of the test() function in __main__. ===VERSIONING=== The following practice, specified in PEP8, no longer makes sense: __version__ = '$Revision: 1.2.3 $' for two reasons: (1) Distributed version control systems make it neccessary to include more than just a revision number. E.g. author name and revision number. (2) It's a revision number not a version number. Instead, the __vcs_id__ variable is being adopted. This expands to, for example: __vcs_id__ = '$Id: example.py,v 1.1.1.1 2001/07/21 22:14:04 goodger Exp $' ===VCS DATE=== Likewise, the date variable has been removed: __date__ = '$Date: 2009/01/02 20:19:18 $' ===CHARACTER ENCODING=== If the coding is explicitly specified, then it should be set to the default setting of ascii. This can be modified if necessary (rarely in practice). Defaulting to utf-8 can cause anomalies with editors that have poor unicode support. """ There are a lot of PEPs that put forward coding style recommendations. Am I missing any important best practices? What is the best python module skeleton code? Update Show me any kind of "best" that you prefer. Tell us what metrics you used to qualify "best".

  • Why am I seeing a crash when trying to call CDHtmlDialog::OnInitDialog()

    - by Tim
    I added a helpAbout menu item to my mfc app. I decided to make the ddlg derive from CDHTMLDialog. I override the OnInitDialog() method in my derived class and the first thing I do is call the parent's OnInitDialog() method. I then put in code that sets the title. On some machines this works fine, but on others it crashes in the call to CDHtmlDialog::OnInitDialog() - Trying to read a null pointer. the call stack has nothing useful - it is in mfc90.dll Is this a potential problem with mismatches of mfc/win32 dlls? It works on my vista machines but crashes on a win2003 server box. BOOL HTMLAboutDlg::OnInitDialog() { // CRASHES on the following line CDHtmlDialog::OnInitDialog(); CString title = "my title"; // example of setting title // i try to get version info //set the title CModuleVersion ver; char filename[ _MAX_PATH ]; GetModuleFileName( AfxGetApp()->m_hInstance, filename, _MAX_PATH ); ver.GetFileVersionInfo(filename); // get version from VS_FIXEDFILEINFO struct CString s; s.Format("Version: %d.%d.%d.%d\n", HIWORD(ver.dwFileVersionMS), LOWORD(ver.dwFileVersionMS), HIWORD(ver.dwFileVersionLS), LOWORD(ver.dwFileVersionLS)); CString version = ver.GetValue(_T("ProductVersion")); version.Remove(' '); version.Replace(",", "."); title = "MyApp - Version " + version; SetWindowText(title); return TRUE; // return TRUE unless you set the focus to a control } And here is the relevant header file: class HTMLAboutDlg : public CDHtmlDialog { DECLARE_DYNCREATE(HTMLAboutDlg) public: HTMLAboutDlg(CWnd* pParent = NULL); // standard constructor virtual ~HTMLAboutDlg(); // Overrides HRESULT OnButtonOK(IHTMLElement *pElement); HRESULT OnButtonCancel(IHTMLElement *pElement); // Dialog Data enum { IDD = IDD_DIALOG_ABOUT, IDH = IDR_HTML_HTMLABOUTDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() DECLARE_DHTML_EVENT_MAP() }; I can't figure out what is going on - why it works on some machins and crashes on others. Both have VS2008 installed EDIT: VS versions VISTA - no crashes 9.0.30729.1 SP 2003 server: (crashes) 9.0.21022.8 RTM

  • Google maps API : V2 : Custom infowindow with bindInfoWindowHtml

    - by PlanetUnknown
    The API documentation gave me hopes last night with "bindInfoWindowHtml". But it doesn't seem to replace the default infoWindow, even when you provide your own class etc. I have tried using other ideas like the labeledmarker. But it doesn't support draggable markers. Hence can't use it in my application. Here is the sample code which shows the info. window inside, the original bubble. Isn't there a way to override that window as well ! ` <style type="text/css"> .infoWindowCustomClass { width: 500px; height: 500px; background-color: #CAEE96; color: #666; } </style> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <title>Google Maps JavaScript API Example</title> <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key="" type="text/javascript"></script> <script type="text/javascript"> function load() { if (GBrowserIsCompatible()) { // Create our "tiny" marker icon var blueIcon = new GIcon(G_DEFAULT_ICON); blueIcon.image = "http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png"; // Set up our GMarkerOptions object markerOptions = { icon:blueIcon }; var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(33.968064,-83.377047), 13); markerOptions.title = "fart"; var point = new GLatLng(33.968064,-83.377047); var marker = new GMarker(point); var tempName = document.getElementById("infoWindowCustom"); marker.bindInfoWindowHtml(tempName); map.addOverlay(marker); } } </script>` And here is the DIV - <DIV id="infoWindowCustom" name="infoWindowCustom" class="infoWindowCustomClass"> Name : <TEXTAREA NAME="nameID" ID="nameID" ROWS="2" COLS="25"></TEXTAREA> Comments : <TEXTAREA NAME="commentsID" ID="commentsID" ROWS="4" COLS="25"></TEXTAREA> </DIV>

  • Should I allow sending complete structures when using PUT for updates in a REST API or not?

    - by dafmetal
    I am designing a REST API and I wonder what the recommended way to handle updates to resources would be. More specifically, I would allow updates through a PUT on the resource, but what should I allow in the body of the PUT request? Always the complete structure of the resource? Always the subpart (that changed) of the structure of the resource? A combination of both? For example, take the resource http://example.org/api/v1/dogs/packs/p1. A GET on this resource would give the following: Request: GET http://example.org/api/v1/dogs/packs/p1 Accept: application/xml Response: <pack> <owner>David</owner> <dogs> <dog> <name>Woofer</name> <breed>Basset Hound</breed> </dog> <dog> <name>Mr. Bones</name> <breed>Basset Hound</breed> </dog> </dogs> </pack> Suppose I want to add a dog (Sniffers the Basset Hound) to the pack, would I support either: Request: PUT http://example.org/api/v1/dogs/packs/p1 <dog> <name>Sniffers</name> <breed>Basset Hound</breed> </dog> Response: HTTP/1.1 200 OK or Request: PUT http://example.org/api/v1/dogs/packs/p1 <pack> <owner>David</owner> <dogs> <dog> <name>Woofer</name> <breed>Basset Hound</breed> </dog> <dog> <name>Mr. Bones</name> <breed>Basset Hound</breed> </dog> <dog> <name>Sniffers</name> <breed>Basset Hound</breed> </dog> </dogs> </pack> Response: HTTP/1.1 200 OK or both? If supporting updates through subsections of the structure is recommended, how would I handle deletes (such as when a dog dies)? Through query parameters?
