• Binding to an XElement

  - by twreid

  I need help binding to an XElement. Basically I am making a editor for certain elements in a web.config and I extract them as XElements and my View binds to a Collection of DataItems which has a property that contains my XElement. When I do Text="{Binding Path=Data, Mode=OneWay, NotifyOnSourceUpdated=True}"/> I get all the text of the Element, but If I try Text="{Binding Path=Data.Elements[], Mode=OneWay, NotifyOnSourceUpdated=True}"/> It doesn't work the TextBox is empty. I am trying to find a way to Template different sections dynamically to make them easier to edit instead of editing raw XMl.

• Syntax errors on Heroku, but not on local server

  - by Phil_Ken_Sebben

  I'm trying to deploy my first app on Heroku (rails 3). It works fine on my local server, but when I pushed it to Heroku and ran it, it crashes, giving a number of syntax errors. These are related to a collection of scopes I use like the one below: scope :scored, lambda { |score = nil| score.nil? ? {} : where('products.votes_count >= ?', score) } it produces errors of this form: "syntax error, unexpected '=', expecting '|' " "syntax error, unexpected '}', expecting kEND" Why is this syntax making Heroku choke and how can I correct it? Thanks!

• How do I check that an entity is unreferenced in JPA?

  - by Martin

  I have the following model @Entity class Element { @Id int id; @Version int version; @ManyToOne Type type; } @Entity class Type { @Id int id; @Version int version; @OneToMany(mappedBy="type") Collection<Element> elements; @Basic(optional=false) boolean disabled; } and would like to allow Type.disabled = true only if Type.elements is empty. Is there a way to do it atomically? I would like to prevent an insertion of an Element in a transaction while the corresponding Type is being disabled by an other transaction.

• Android preferencesActivity setDefaultValue() not working?

  - by Nick

  I'm extending PreferenceActivity for my settings screen. In this preference activity i have a couple of preferences one of which is custom made. The problem is as follows: in this custom preference (which extends from ListPreference) i want to be able to set the default value, so i override the setDefaultValue() method. In this method i do some parsing so it'll take the correct value. When i'm trying to read this value with the getValue() function it just returns null. So i figured, what happens when i just put some hardcoded value in there (you know, maybe i did something wrong, wouldn't be the first time). Well, i still get null back. Any ideas what i'm doing wrong? Edit: Setting the defaultValue in the xml file isn't really an option because the values aren't known until i retrieve them. I made a workaround: When app is started for the first time: get data Set the values in the preference. This way i set the default preference when i'm collection the data

• will_paginate route only works on page > 1

  - by Avishai

  I have the following routes defined: map.resources :categories, :has_many => :downloads map.resources :downloads, :member => {:go => :get}, :collection => {:tag => :get} map.connect '/downlods/page/:page', :controller => 'downloads', :action => 'index' map.connect '/categories/:category_id/downloads/page/:page', :controller => 'downloads', :action => 'index' For some reason, the first page that the will_paginate helper is called on causes links with ?page=2 to be rendered, while subsequent pages have links with /downloads/page/2. Do you know what might be causing this?

• Can I bypass an intermediate object in hibernate

  - by Jherico

  I have top level entities TRACK, MEDIA_GROUP and MEDIA, each with an integer primary key. I also have a join table from TRACK to MEDIA_GROUP which is 1:1 and MEDIA has a FK column into MEDIA_GROUP. I'm trying to find a way in hibernate to map a collection of Media directly into the Track object, bypassing the creation of a MediaGroup object. Basically I want to turn this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA_GROUP <-> MEDIA into this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA But the join column between MEDIA_TRACK_MAP and MEDIA isn't the primary key of MEDIA.

• Cascading MVC controllers with CatchAll Routes

  - by Richard

  Hi, I have an MVC app which has its routes defined with the final route being a catch all route to a "PageController" for a database driven collection of pages. What I want to achieve is to be able to plugin to the app a second controller to the catch all route which the first controller passes on to if it does not find the url recieved in the database. Effectively I want to queue up controllers with catch all actions: public ActionResult PageCatchall(string url) { var page = repository.Get<Page>(string url); if (page != null) { // Handle the request return View(page) } // Otherwise pass to a new controller ???? } Anyone have any good ideas as to how to solve this? I have tried RedirectToAction but that requires that the next controller has a different route to the action. I have tried ActionInvoker but this failed to work the way I did it.

• Show/Hide GridView Header in ListView

  - by Chris

  I have a ListView in WPF, and I want to hide the headers for the ListView when the List the ItemsSource is bound to is null, and display the headers when the ItemsSource is not null and has at least 1 item in the collection. I have found the code online to hide the ListView headers like this: <Window.Resources> <Style x:Key="HideListViewHeaders" TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="Visibility" Value="Collapsed" /> </Style> </Window.Resources> Thanks for any help!

• Calling a method on a Object says "disallows late binding"

  - by Maury Markowitz

  I have a calls called DtaDate that stores an integer "key", a string name, a string for the date, and a Date object that is created from that string. I have some code that needs to accept a date-like object. I'd like the user to be able to pass in anything date like - a Date object which I'll extract the information from, another DtaDate, a string with the date in it, or even the key, which I'll use to look up the DtaDate from a collection. So I have this: Friend Sub New(NameIn As String, DateFormulaIn As String, Optional FromDateIn As Object = Nothing) [stuff that works] [check that we got a FromDateIn...] If TypeOf FromDateIn Is DtaDate Then fdk = FromDateIn.Key Ans.FromDate = fdk VB tells me that "Option Strict On disallows late binding". The other cases, where a string or integer is the TypeOf, I use CInt or CStr. But this is the first time I've actually run into a case where the casting is a non-base type. What's the trick?

• MySQL: Matching inexact values using "ON"

  - by Brad

  I'm way out of my league here... I have a mapping table (table1) to assign particular values (value) to a whole number (map_nu). My second table (table2), is a collection of averages (avg) (I couldn't figure out how to properly make a markdown table, please feel free to edit!) table1: table2: (value)(Map_nu) (avg) ---- ----- 1 1 1.111 1.045 2 1.2 1.09 3 1.33333 1.135 4 1 1.18 5 1.389 1.225 6 1.42 1.27 7 1.07 1.315 8 1.36 9 1.405 10 I need to find a way to match the averages from table2 to the closest value in table1. It only need to match to the 2 digit past the decimal, so I've added the Truncated function SELECT map_nu FROM `table1` JOIN table2 ON TRUNCATE(table1.value,2)=TRUNCATE(table2.avg,2) I still miss the values that don't match the averages exactly. Is there a way to pick the nearest truncated value? Thanks!

• How do I identify where the POST data sent to a PHP script came from?

  - by Mike Turley

  I have a ton of data collection forms on my website, and I wrote a PHP script to handle all the data. All the forms have that one script as their action, and POST as the method. The handler emails a copy of the data to me, and I'd like for the emails I get to contain the URL of the form where they originated. Is there any way in PHP to get the url of the form which was submitted to the script? Or do I have to add an extra hidden field in every form with its URL?

• What do I use for a J2ee website?

  - by johnny

  Not sure if I asked this correctly. I am trying to see what I need to create an website that uses MVC and that connects to legacy multiple databases, brining back those database info into one page. I wanted the site to be MVC but am not sure where to begin. Do I use Spring? What do I use for an server? Jboss and apache? Hibernate? I'm just kind of lost on how to proceed. It's not a straight forward a asp.net mvc or a php framwork. A major concern is the collection of data from multiple legacy databases and bringing that data back into one page. Thanks.

• linq with Include and criteria

  - by JMarsch

  How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

• attaching multiple files to a domain class

  - by Emyr

  I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

• Magento - createBlock() in controller, can I access this in layout.xml?

  - by pspahn

  I have an index controller with a view action that does the following: echo $this->getLayout() ->createBlock('core/template','builder') ->setTemplate('pages/builder/view.phtml') ->setHeaderText($extra->getHeaderText()) ->setFooterText($extra->getFooterText()) ->setProducts($collection) ->toHtml(); Based on this, I am trying to perform layout updates in builder.xml (which is being set in the module's config.xml). However, I am not sure if you can target blocks instantiated in this manner. Based on the above block creation, am I able to perform the following: <layout version="0.1.0"> <builder_index_view> <!-- shouldn't this reference the createBlock() name argument? --> <reference name="builder"> <block type="page/html_header" name="builder.header" as="builder.header" template="pages/builder/header.phtml"/> </reference> </builder_index_view> </layout>

• Fastest method for SQL Server inserts, updates, selects

  - by Ian

  I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• Freezing a listboxitem while items are being added

  - by siz

  We have a ListBox that has a number of items. Items are inserted into the ListBox via an ObservableCollection. Some of these items can be edited right in the ListBox. However, if an item is added at an index < the edited item's index, the entire content of the ListBox moves down. What we'd like to do is the following: if an item is in edit mode, we'd like to freeze its position on the screen. It is fine if items are added to the collection and the UI around the item changes. But the position of the item should remain constant on the screen. The only thing I've been able to do so far is attach to the ScrollChanged event and, at most, use either BringIntoView or ScrollIntoView methods to ensure that the item is always displayed somewhere in the UI, but I am unable to lock down its position. Has anyone done something like this and help out?

• Why the data binding in this validation example works in WPF?

  - by MartyIX

  I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

• ActiveRecord find all parents that have associated children

  - by brad

  I don't know why I can't figure this out, I think it should be fairly simple. I have two models (see below). I'm trying to come up with a named scope for SupplierCategory that would find all SupplierCategory(s) (including :suppliers) who's associated Supplier(s) are not empty. I tried a straight up join, named_scope :with_suppliers, :joins => :suppliers which gives me only categories with suppliers, but it gives me each category listed separately, so if a category has 2 suppliers, i get the category twice in the returned array: Currently I'm using: named_scope :with_suppliers, :include => :suppliers and then in my view I'm using: <%= render :partial => 'category', :collection => @categories.find_all{|c| !c.suppliers.empty? } %> Not exactly eloquent but illustrates what I'm trying to achieve. Class Definitions class SupplierCategory < AR has_many :suppliers, :order => "name" end class Supplier < AR belongs_to :supplier end

• Json.Net CustomSerialization

  - by BonyT

  I am serializing a collection of objects that contains a dictionary called dynamic properties. The default Json emitted looks like this: [{"dynamicProperties":{"WatchId":7771,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5580"}}, {"dynamicProperties":{"WatchId":7769,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5574"}}, {"dynamicProperties":{"WatchId":7767,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5572"}}, {"dynamicProperties":{"WatchId":7765,"Issues":0,"WatchType":"y","Location":"Equinix Source","Name":"highlight_SM"}}, {"dynamicProperties":{"WatchId":8432,"Issues":0,"WatchType":"y","Location":"Test Devices","Name":"Cisco1700PI"}}] I'd like to produce Json that looks like this: [{"WatchId":7771,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5580"}, {"WatchId":7769,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5574"}, {"WatchId":7767,"Issues":0,"WatchType":"x","Location":"Equinix Source","Name":"PI_5570_5572"}, {"WatchId":7765,"Issues":0,"WatchType":"y","Location":"Equinix Source","Name":"highlight_SM"}, {"WatchId":8432,"Issues":0,"WatchType":"y","Location":"Test Devices","Name":"Cisco1700PI"}] From reading the Json.Net documentation it looks like I could build a CustomContractResolver for my class, but I cannot find any details on how to go about this... Can anyone shed any light on the direction I should be looking in?

• building treeview

  - by DJPlayer

  I'm dynamically building a treeview given numerous stored procedures. the structure goes like this: OwnerRPColl.Search2() For Each root As OWNER_RP In OwnerRPColl Dim nd_Root As New TreeNode nd_Root = TreeView1.Nodes.Add(root.OWNER_RP_BUSNS_NAME) bldg.ID = root.ID bldgColl.Search(bldg.ID) For Each firstChild As BLDG In bldgColl Dim nd_lvl_One As New TreeNode With nd_lvl_One .Text = firstChild.BLDG_NAME_1 .Tag = firstChild.ID End With problem being is that I need to have labels for these.. meaning the first level of the treeview needs to say "users" when expanded displays users. Each of these users can have a building. The world building needs to be the example option, which then displays the building.. essentially I need a slick way to add the word in for the expanding level (instead of the value in the collection).

• Squid logs on mongodb

  - by user306241

  Hi, I'm planning to log my squid instances to a mongodb, but the actual problem is that we have a huge traffic to be logged, every access authenticated with user/pass. Eventually we have to make some reports based on logs. I was thinking to insert the logs distributed by months and by users, so my collection will look like this: {month: 'april', users: [{user: 'loop0', logs: [{timestamp: 12345678.9, url: 'http://stackoverflow.com/question/ask', ... }]}] So if I want to generate my reports based on the month of april I just have to get the right month instead of looking in zillions of lines to fetch the lines that timestamp match between April, 1 and April, 30. Of course this type of insert will be slower than just insert the log line directly. So my question is: is there a best way to do this? Nowadays we have around 12 million lines of log by day.

• iqueryable select/where not working

  - by Steve

  I have two tables Boxer and Prospect. Boxers has general stuff like name and and dob etc and a BoxerId While Prospect contains only one value (at the moment) which is a boxerId. If a boxer is a prospect(up and coming boxer) there Id will be in the prospect table. This works fine but now I want to select all boxers that are prospects public static IQueryable<Boxer> IsProspect(this IQueryable<Boxer> query) { //this does not filter down to only prospects!!! return query.Where(x => x.Prospect != null); } This is the function I call using: var repository = GetRepository<Boxer>(); var boxers = repository.Query().IsProspect(); I would hope this would filter my collection of all boxers down to just boxers that are prospects! Oddly it doesnt filter it but if i hover over my boxers object and look at each boxer during debugging I can see "IsProspect" true or false correctly
