• Process results of conditional split in SSIS

  - by Robert

  I have a Data Flow Task and am connecting to a database via an OLE DB Source component to extract data. This data feeds into a Conditional Split component to separate the data based on a simple expression. After the evaluation of this expression, the data will end up in either of two locations: LocationA or LocationB. Alright, I have that all set up and working properly. Once the data is separated into these two locations, additional processing is to be done on the records. Here's where I am stuck: I need the the processing of records in LocationA to occur before the processing of records in LocationB. Is there a way to set precedence of which tasks occur before others? If not, what is the best way to handle this? I was thinking I may need to write the data in LocationA and LocationB back out to the database and create a new data flow task in the control flow to handle the order of which these records must be dealt with. Any help is greatly appreciated!

• Is an LSA MSV1_0 subauthentication package needed for some impersonation use cases?

  - by Chris Sears

  Greetings, I'm working with a vendor who has implemented some code that uses a Windows LSA MSV1_0 subauthentication package (MSDN info if you're interested: http://msdn.microsoft.com/en-us/library/aa374786(VS.85).aspx ) and I'm trying to figure out if it's necessary. As far as I can tell, the subauthentication routine and filter allow for hooking or customizing the standard LSA MSV1_0 logon event processing. The issue is that I don't understand why the vendor's product would need these capabilities. I've asked them and they said they use it to perform impersonation. The product definitely does need to do impersonation, but based on my limited win32 knowledge, they could get the functionality they need using the normal auth APIs (LsaLogonUser, ImpersonateLoggedOnUser, etc) without the subauthentication package. Furthermore, I've worked with a number of similar products that all do impersonation, and this is the only one that's used a subauthentication package. If you're wondering why I would care, a previous version of the product had a bug in the subauthentication package dll that would cause lockups or bluescreens. That makes me rather nervous and has me questioning the use of such a low-level, kernel sensitive interface. I'd like to go back to the vendor and say "There's no way you could need an LSA subauth package for impersonation - take it out", but I'm not sure I understand the use cases and possible limitations of the standard win32 authentication/impersonation APIs well enough to make that claim definitively. So, to the win32 security gurus out there, is there any reason you would need an LSA MSV1_0 subauthentication package if all you were doing is impersonation? Thanks in advance for any thoughts!

• Facial recognition/detection PHP or software for photo and video galleries

  - by Peter

  I have a very large photo gallery with thousands of similar people, objects, locations, things. The majority of the people in the photos have their own user accounts and avatar photos to match. There are also logical short lists of people potentially in the photo based on additional data available for each photo. I allow users to tag photos with their friends and people they know but an automated process would be better. I've used photo tagger/finder from face.com integrating with Facebook photos and the Google Picasa photo tagger for personal albums also does the same thing and is exactly what I'm looking to do. Is there a PHP script, API for Google Picasa, face.com or other recognition service or any other open source project that provides server-side facial recognition and/or grouping photos by similarity? Examples: As you can see, various photo sharing sites offer the feature, but are there any that provide an API for images stored on my own server or something extensive enough to link into my own gallery and tagging system? viewdle - Face recognition/Tagging for video PHP - Face detection in pure PHP Xarg OpenCV Face.com - app for finding and tagging photos in Facebook Google Picasa - photo sharing TeraSnaps - photo sharing site Google Portrait - photo grouping from Google Image results FaceOnIt - Video face recognition PittPatt - Detection, Recognition, Video Face Mining BetaFace ChaosFace - Real-time Face Detector

• C++ design question on traversing binary trees

  - by user231536

  I have a binary tree T which I would like to copy to another tree. Suppose I have a visit method that gets evaluated at every node: struct visit { virtual void operator() (node* n)=0; }; and I have a visitor algorithm void visitor(node* t, visit& v) { //do a preorder traversal using stack or recursion if (!t) return; v(t); visitor(t->left, v); visitor(t->right, v); } I have 2 questions: I settled on using the functor based approach because I see that boost graph does this (vertex visitors). Also I tend to repeat the same code to traverse the tree and do different things at each node. Is this a good design to get rid of duplicated code? What other alternative designs are there? How do I use this to create a new binary tree from an existing one? I can keep a stack on the visit functor if I want, but it gets tied to the algorithm in visitor. How would I incorporate postorder traversals here ? Another functor class?

• How could I make this display for listbox?

  - by baron

  Hello everyone, I have a databound listbox which is actually displaying two columns of data. It is displayed as follows: <UserControl.Resources> <DataTemplate x:Key="AlignedPairs"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="10" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding Fruits}" Grid.Column="0" /> <TextBlock Text="->" TextAlignment="Center" Grid.Column="1" /> <TextBlock Text="{Binding Colors}" Grid.Column="3" /> </Grid> </DataTemplate> </UserControl.Resources> <ListBox Name="lbStuff" Grid.ColumnSpan="2" Grid.Row="1" ItemTemplate="{StaticResource AlignedPairs}"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch" /> </Style> </ListBox.ItemContainerStyle> </ListBox> Then Itemsource set in codebehind. Based on some logic however, I would like to set either a line or a item in one of the columns, e.g. a fruit to red, or the line to bold. I have code to work out which Fruit or Color I would like to differentiate (by color/bold) in the code behind, but I can't figure out, especially given the custom listbox display, how I could go about setting a particular item to a different color/bold. Does anyone have any ideas? Let me know if any further code is required. Cheers.

• jQuery validation: how to customize trigger and response

  - by user302307

  I am new with jQuery. I have a servlet based application which render an HTML form. This form is submitted via a function and the submit button IS NOT submit button in HTML. It's a regular button that calls a javascript function to do the submission. When running the submission function, the servlet also run a function called doCheck() which is in javascript. This doCheck() function can be defined per page basis. if doCheck returns false, then the servlet will stop the submission; else it will submit the form. I want to use jQuery validation to fit the servlet application. Is there a way to customize jQuery validation to be triggered manually (ie. only when doCheck() is executed) but at the same time provides continuous check on the UI (ie. if one type invalid number in date field, it will gives the appropriate msg when onblur event happen)? Is there a way to make jQuery validation return true or false? Thank you.

• Silverlight 4, Out of browser, Printing, Automatic updates

  - by minal

  I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

• C++ resize a docked Qt QDockWidget programmatically?

  - by Zac

  I've just started working on a new C++/Qt project. It's going to be an MDI-based IDE with docked widgets for things like the file tree, object browser, compiler output, etc. One thing is bugging me so far though: I can't figure out how to programmatically make a QDockWidget smaller. For example, this snippet creates my bottom dock window, "Build Information": m_compilerOutput = new QTextEdit; m_compilerOutput->setReadOnly(true); dock = new QDockWidget(tr("Build Information"), this); dock->setWidget(m_compilerOutput); addDockWidget(Qt::BottomDockWidgetArea, dock); When launched, my program looks like this: http://yfrog.com/6ldreamidep (bear in mind the early stage of development) However, I want it to appear like this: http://yfrog.com/20dreamide2p I can't seem to get this to happen. The Qt Reference on QDockWidget says this: Custom size hints, minimum and maximum sizes and size policies should be implemented in the child widget. QDockWidget will respect them, adjusting its own constraints to include the frame and title. Size constraints should not be set on the QDockWidget itself, because they change depending on whether it is docked Now, this suggests that one method of going about doing this would be to sub-class QTextEdit and override the sizeHint() method. However, I would prefer not to do this just for that purpose, nor have I tried it to find that to be a working solution. I have tried calling dock-resize(m_compilerOutput-width(), m_compilerOutput-minimumHeight()), calling m_compilerOutput-setSizePolicy() with each of its options...nothing so far has affected the size. Like I said, I would prefer a simple solution in a few lines of code to having to create a sub-class just to change sizeHint(). All suggestions are appreciated.

• Gridview empty when SelectedIndexChanged called

  - by xan

  I have a DataGrid which is being bound dynamically to a database query. The user enters some search text into a text field, clicks search, and the code behind creates the appropriate database query using LINQ (searches a table based on the string and returns a limited set of the columns). It then sets the GridView datasource to be the query and calls DataBind(). protected void btnSearch_Click(object sender, EventArgs e) { var query = from record in DB.Table where record.Name.Contains(txtSearch.Text) //Extra string checking etc. removed. select new { record.ID, record.Name, record.Date }; gvResults.DataSource = query; gvResults.DataBind(); } This works fine. When a user selects a row in the grid, the SelectedIndexChanged event handler gets the id from the row in the grid (one of the fields), queries the full record from the DB and then populates a set of editor / details fields with the records full details. protected void gvResults_SelectedIndexChanged(object sender, EventArgs e) { int id = int.Parse(gvResults.SelectedRow.Cells[1].Text); DisplayDetails(id); } This works fine on my local machine where I'm developing the code. On the production server however, the function is called successfully, but the row and column count on gvResults, the GridVeiw is 0 - the table is empty. The GridView's viewstate is enabled and I can't see obvious differences. Have I made some naive assumptions, or am I relying on something that is likely to be configured differently in debug? Locally I am running an empty asp.net web project in VS2008 to make development quicker. The production server is running the sitecore CMS so is configured rather differently. Any thoughts or suggestions would be most welcome. Thanks in advance!

• PHP File upload fails with blank screen when size exceeds 742 KB.

  - by user284839

  Hi friends, This is one of the most bizarre errors I've come across. So I've written a little file upload web app for my friend and it works fine for any file less than or equal to 742kB in size. Needless to say, I arrived at this precise number based on relentless testing. Weird part is that if the file size is just a few KB more, for example 743 or 750, I get an error saying "MySQL has gone away". But if it is 1MB or more, then I just get a blank screen. And it happens in less than 2 seconds after I hit the upload button. So it doesn't look like a time-out to me. I checked out the PHP.ini file for post size and upload size, they are all set to 5 MB or more. And the timeout is set to 60 seconds. The uploaded file sits in MySQL database in a field of datatype mediumblob. I tried changing that to longblob. But that didn't help either. Any help? Thanks for reading, Girish

• playframework auto-test Jenkins CI wait for completion?

  I am trying to set up Jenkins CI for a playframework.org application but am having trouble properly launching play after the auto-test command is run.

• Why would a SQL query JOIN on the same table twice with the same condition?

  - by Scott Leis

  I'm working on changes to a SQL Server v8 database developed by someone else, and have found something that seems (based on my limited SQL knowledge) strange and pointless. One of the views has a query that does a LEFT OUTER JOIN twice on the same table with the same condition. Is there any reason for doing this? The query is below. See the second- and third-last lines that both join the "te_SDE_Survey" table on the "SDE_ID" field. Also note these lines set two different aliases for the table, and both aliases are used in the SELECT part of the query. SELECT vs.SLMS_Code, vs.Retail_Date, vs.TagNo, vs.Rego, vs.Model, vs.Company, vs.AccountType, viqdp.SDE_ID, bd.Debit_Date, isu.Survey_Date, CASE WHEN isu.Q6 IS NOT NULL THEN isu.Q6 ELSE CASE WHEN returned_surveys.survey_date IS NULL THEN CASE WHEN (viqdp.expiryDate < getdate() AND cs.sup1 IS NULL AND cs.sup2 IS NULL AND cs.sup3 IS NULL AND cs.sup5 IS NULL AND cs.sup8 IS NULL AND cs.sup9 IS NULL) THEN 'E' WHEN (viqdp.expiryDate < getdate() AND cs.sup1 = 'F' AND cs.sup2 = 'F' AND cs.sup3 = 'F' AND cs.sup5 = 'F' AND cs.sup8 = 'F' AND cs.sup9 = 'F') THEN 'E' WHEN cs.sup1 = 'T' THEN 'S' WHEN cs.sup2 = 'T' AND (cs.sup8 = 'F' AND cs.sup9 = 'F') THEN 'D' WHEN cs.sup3 = 'T' AND (cs.sup8 = 'F' AND cs.sup9 = 'F') THEN 'D' WHEN cs.sup5 = 'T' AND (cs.sup8 = 'F' AND cs.sup9 = 'F') THEN 'D' WHEN cs.sup8 = 'T' AND (cs.sup2 = 'F' AND cs.sup3 = 'F' AND cs.sup5 = 'F') THEN 'E' WHEN cs.sup9 = 'T' AND (cs.sup2 = 'F' AND cs.sup3 = 'F' AND cs.sup5 = 'F') THEN 'E' WHEN (cs.sup8 = 'T' OR cs.sup9 = 'T') AND (cs.sup2 = 'T' OR cs.sup3 = 'T' OR cs.sup5 = 'T') THEN 'S' END WHEN (tey.survey_expire_method = 'pre2008') THEN CASE WHEN (datediff(month, viqdp.generate_date, returned_surveys.survey_date) 1) THEN 'E' END WHEN (tey.survey_expire_method = 'expiryDateColumn') THEN CASE WHEN (returned_surveys.survey_date viqdp.expiryDate) THEN 'E' END END END AS score_or_exclusion_status, CASE WHEN (bd.explanation IS NULL) THEN '' ELSE bd.explanation END AS explanation, tey.te_Year FROM dbo.te_Vehicle_Sale vs INNER JOIN dbo.te_Year tey ON vs.Retail_Date = tey.Start_Date AND vs.Retail_Date <= tey.End_Date LEFT OUTER JOIN dbo.Bad_Data bd ON vs.TagNo = bd.TagNo LEFT OUTER JOIN dbo.te_Vehicle_SDESurvey viqdp ON vs.TagNo = viqdp.TagNo LEFT OUTER JOIN dbo.te_SDE_Survey isu ON viqdp.SDE_ID = isu.SDE_ID LEFT OUTER JOIN dbo.te_SDE_Survey returned_surveys ON viqdp.SDE_ID = returned_surveys.SDE_ID LEFT OUTER JOIN dbo.te_SDE_Contact_Suppression cs ON viqdp.SDE_ID = cs.SDE_ID

• WPF - Getting the value of one a DataGridCell from within DataTemplateSelector

  - by Andy T

  Hi, I'm using DataTemplateSelector with the WPFToolkit DataGrid. I want to select the editing template for one cell based on the value of another cell on the same row. The DataTemplateSelector's SelectTemplate method takes two arguments: one is the data item displayed by the grid row, the other is the grid cell. What I want to know is how to get the value of another cell from within the SelectTemplate method. However, I'm not sure of the correct way to get this information by accessing properties of the cell. public class RangeValuesEditTemplateSelector : DataTemplateSelector { public DataTemplate NumberTemplate{get; set;} public DataTemplate TextTemplate{get; set;} public override DataTemplate SelectTemplate(object item, DependencyObject container) { //TODO: need to find the correct way to populate the if condition below DataGridCell theCell = container as DataGridCell; if (theCell.something.somethingElse) { return NumberTemplate; }else{ return TextTemplate; } } } Can anyone help? Many thanks in advance. AT

• Adding AJAX call to function triggered popup blocker

  - by jerrygarciuh

  Hi folks, I have a client who wants to open variously sized images in a centered popup. I tried to get them to use FancyBox but they don't want interstitial presentation, so... I initially was opening a generic popup which resized and centered onload based on image size but they don't like the shift so I added a PHP script to echo the sizes and used jQuery to fetch the size info to feed into the pop up call. But it appears the delay this causes is setting off all popup blockers. Here is the JS $("#portfolioBigPic").click(function () { var src = $("#portfolioBigPic").attr('src'); var ar = src.split('/'); var fname = ar.pop(); fname = '/g/portfolio/clients/big/' + fname; $.get("imgsize.php", { i: fname}, function(data){ var dim = data.split(","); popit(fname,dim[0],dim[1]); }); }); function popit(img,w,h) { var features = 'width='+w+',height='+h+', toolbar=0, location=0, directories=0, status=0, menubar=0, scrollbars=0, resizable=1,'; var left = (screen.width/2)-(w/2); var top = 0; features += 'top='+top+',left='+left; bigpic = window.open('portfolioBigPic.php?img='+img, 'bigpic',features); bigpic.focus(); } The only difference between dodging the blockers and failing is that I added the AJAX .get and use it to specify w and h. Any thoughts on how to avoid this? Maybe I should use PHP to get widths and heights of all the big pics and write a JS array of them when this page loads? Am I right that the delay caused by fetching the data is tripping the blockers? Thoughts? Any advice much appreciated. JG

• Updating asp:SqlDataSource Parameter via asp:LinkButton

  - by Mattec

  I'll try to explain what I'm doing the best I can, but I'm pretty new to asp.net so be patient with me. I have a SqlDataSource which returns a simple select statement based on the WHERE clause using @COURSE_ID What I want to-do is every time any one of 2 (this will change as it's going to be generated) asp:LinkButtons are pressed, they will change the @COURSEID value which i'd like to associate with the specific button.

• SVN Question regarding branching and third party vendor branching

  - by fritzone

  Hi, We are developing an application which consists of: a source code base given to us by a partner infrequently. This is a somewhat working code, "final" version of something. They have their own release cycle and version tracking. on the code base above we make our changes. These can be either bugfixes or development of new features. Till now, we managed to create some code mayhem, as a result we would like to put all this in a SVN repository. I would like to ask you what you think is the best practice for this to happen with the less pain. The followings are our things that we consider important: We would like to track our bugfixes/changes since we cannot send back bugfixes to our software vendor, but we can report a bug (and they might or might not fix it). All we develop on their code remains "in-house" they are not interested in our changes. As long as we don't get a new codebase from the vendor, we consider their latest version to be the stable one we are working on. This might be branched down further, but the result is always a stable trunk, the build is done based on this "stable" trunk. When the vendor releases a new version we would like to merge our "stable" trunk (which contains a lot of changes) with their changes, thus creating a new "stable" trunk. For each version we deploy (to clients) we should be able later to fix bugs only on that version, for clients who have installed our system using that specific version There are more developers working on the codebase... (as usual :) Thanks a lot for the tips.

• IE7 issue - cannot download streamed file when Automatic prompting for file downloads is disabled

  - by Jai ganesh K

  Hi, My application is J2EE (JSP/Servlet) based. I encounter an issue when i try to open a new window (pop-up) from JSP and call a Servlet action (e.g. Streamer.do) which streams a PDF file inside that pop-up. Problem: While IE 7 - Tools - Internet Options - Security - Custom Level - Downloads - Automatic prompting for file downloads is Disabled and while pop-up window get opened, I am unable to download the file (Save/Open prompt is not comming up). In contrast, when I enable this option, I am able to download. But this option sometimes would be disabled in some environments. While testing this in Mozilla Firefox 3.0/3/5/IE6 it is working fine without any settings change. When i check it to enable i then get the Save/Open prompt to work correctly. This should be problem with IE7. Can anybody help us with Javascript or any working settings which doesnt care whether the "Automatic prompting for downloads" option in IE7 is enabled. Any help in this would be much appreciated. Regards! Jai

• How to use class_eval <<-"end_eval" in Ruby? Not parsing correctly

  - by viatropos

  I would like to define dynamic methods based on some options people give when instantiating it. So in their AR model, they'd do something like this: acts_as_something :class_name => "CustomClass" I'm trying to implement that like so: module MyModule def self.included(base) as = Config.class_name.underscore foreign_key = "#{as}_id" # 1 - class eval, throws these errors # ~/test-project/helpers/form.rb:45: syntax error, unexpected $undefined # @ ||= MyForm.new( # ^ # ~/test-project/helpers/form.rb:46: syntax error, unexpected ',' #~/test-project/helpers/form.rb:48: syntax error, unexpected ')', # expecting kEND from ~/test-project/helpers.rb:12:in `include' base.class_eval <<-"end_eval", __FILE__, __LINE__ attr_accessor :#{as} def #{as} @#{as} ||= MyForm.new( :id => self.#{foreign_key}, :title => self.title ) @#{as} end end_eval end end But it's throwing a bunch of errors I've printed in the comments. Am I using this incorrectly? What are some better ways I can define dynamic method names and dynamic names inside the method like this? I see people use this often instead of define_method (see these classes in resource_controller and couchrest toward the bottom). What I missing here? Thanks for the help

• Fill 2D area bound by vertices in XNA

  - by oakskc

  I'm learning XNA by doing and, as the title states, I'm trying to see if there's a way to fill a 2D area that is defined by a collection of vertices on a plane. I want to fill with a color, not a file-based texture. For an example, take a rounded rectangle whose vertices are defined by four quarter-circle triangle fans. The vertices are defined by building a collection of triangles, but the triangles may not be adjacent. Additionally, I would like to fill it with more than a single color -- i.e. divide the bound area into four vertical bands and have each a different color. You don't have to provide me the code, pointing me towards resources will help a great deal. I can be handy with Google (which I did try first, but have failed miserably). This is as much an exploration into "what's appropriate for XNA" as it is the implementation of it. Being pretty new to XNA, I'm wanting to also learn what should and shouldn't be done on top of what can and can't be done.

• ACL architechture for a Software As a service in Spring 3.0

  - by geoaxis

  I am making a software as a service using Spring 3.0 (Spring MVC, Spring Security, Spring Roo, Hibernate) I have to come up with a flexible access control list mechanism.I have three different kinds of users System (who can do any thing to the system, includes admin and internal daemons) Operations (who can add and delete users, organizations, and do maintenance work on behalf of users and organizations) End Users (they belong to one or more organization, for each organization, the user can have one or more roles, like being organization admin, or organization read-only member) (role like orgadmin can also add users for that organization) Now my question is, how should i model the entity of User? If I just take the End User, it can belong to one or more organizations, so each user can contain a set of references to its organizations. But how do we model the users role for each organization, So for example User UX belongs to organizations og1, og2 and og3, and for og1 he is both orgadmin, and org-read-only-user, where as for og2 he is only orgadmin and for og3 he is only org-read-only-user I have the possibility of making each user belong to one organization alone, but that's making the system bounded and I don't like that idea (although i would still satisfy the requirement) If you have a better extensible ACL architecture, please suggest it. Since its a software as a service, one would expect that alot of different organizations would be part if the same system. I had one concern that it is not a good idea to keep og1 and og2 data on the same DB (if og1 decides to spawn a 100 reports on the system, og2 should not suffer) But that is some thing advanced for now and is not directly related to ACL but to the physical distribution of data and setup of services based on those ACLs This is a community Wiki question, please correct any thing which you wish to do so. Thanks

• What is a good embeddable Java LDAP server?

  - by LeedsSideStreets

  I'm working on a Java web application that integrates with a few other external applications that are deployed along with it. Authentication information must be synchronized across everything and the other applications want to authenticate against LDAP. The application will be deployed in environments where there will be no other LDAP server for everything to use; I have to provide it. My solution so far has been to use Penrose Server as a standalone app, which I set up to examine tables in the main application's database and publish LDAP based on that. It works well, but it would be nice to have something that can be embedded into the main application itself to simplify deployment. It looks like Penrose can be embedded, but the documentation can be a bit spotty or out-of-date (though it seems to be actively developed). It could be an acceptable solution, but if there is another out there that is known to work well in an embedded configuration I might want to check it out. I'm also concerned about GPL issues with Penrose. I'm not at liberty to GPL the source code for the application. I don't believe it was an issue running it standalone, but embedding it may be no-no... anybody know for sure? A permissive license would be good in order to avoid these issues. Requirements: LDAP v3 Must be able to be have the directory contents updated while running, either programmatically or by another means like syncing with the database as Penrose does Easy to configure (no additional configuration for the app at deployment time would be ideal) So far I've briefly looked at ApacheDS and OpenDS which seem to be embeddable. Does anyone have experience with this kind of thing?

• Migrating data from Plone to Liferay, or how could I retrieve information from Plone's Data.fs

  - by brandizzi

  Hello, all. I need to migrate data from a Plone-based portal to Liferay. Has anyone some idea on how to do it? Anyway, I am trying to retrieve data from Data.fs and store it in a representation easier to work, such as JSON. To do it, I need to know which objects I should get from Plone's Data.fs. I already got the Products.CMFPlone.Portal.PloneSite instance from the Data.fs, but I cannot get anything from it. I would like to get the PloneSite instance and do something like this: >>> import ZODB >>> from ZODB import FileStorage, DB >>> path = r"C:\Arquivos de programas\Plone\var\filestorage\Data.fs" >>> storage = FileStorage.FileStorage(path) >>> db = DB(storage) >>> conn = db.open() >>> root = conn.root() >>> app = root['Application'] >>> plone_site = app.getChildNodes()[13] # 13 would be index of PloneSite object >>> a = plone_site.get_articles() >>> for article in a: ... print "Title:", a.title ... print "Content:", a.content Title: <some title> Conent: <some content> Title: <some title> Conent: <some content> Of course, it did not need to be so straightforward. I just want some information about the structure of PloneSite and how to recover its data. Has anyone some idea? Thank you in advance!

• How do I pass a cookie to a Sinatra app using curl?

  - by Brandon Toone

  I'm using the code from the example titled "A Slightly Bigger Example" from this tutorial http://rubylearning.com/blog/2009/09/30/cookie-based-sessions-in-sinatra/ to figure out how to send a cookie to a Sinatra application but I can't figure out how to set the values correctly When I set the name to be "brandon" in the application it creates a cookie with a value of BAh7BiIJdXNlciIMYnJhbmRvbg%3D%3D%0A which is a url encoding (http://ostermiller.org/calc/encode.html) of the value BAh7BiIJdXNlciIMYnJhbmRvbg== Using that value I can send a cookie to the app correctly curl -b "rack.session=BAh7BiIJdXNlciIMYnJhbmRvbg==" localhost:9393 I'm pretty sure that value is a base64 encoding of the ruby hash for the session since the docs (http://rack.rubyforge.org/doc/classes/Rack/Session/Cookie.html) say The session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session). I thought that meant all I had to do was base64 encode {"user"=>"brandon"} and use it in the curl command. Unfortunately that creates a different value than BAh7BiIJdXNlciIMYnJhbmRvbg==. Next I tried taking the base64 encoded value and decoding it at various base64 decoders online but that results in strange characters (a box symbol and others) so I don't know how to recreate the value to even encode it. So my question is do you know what characters/format I need to get the proper base64 encoding and/or do you know of another way to pass a value using curl such that it will register as a proper cookie for a Sinatra app?

• Add KO "data-bind" attribute on $(document).ready

  - by M.Babcock

  Preface I've rarely ever been a JS developer and this is my first attempt at doing something with Knockout.js. The question to follow likely illustrates both points. Backgound I have a fairly complex MVC3 application that I'm trying to get to work with KO (v2.0.0.0). My MVC app is designed to generically control which fields appear in the view (and how they are added to the view). It makes use of partial views to decide what to draw in the view based on the user's permissions (If the user is in group A then show control A, if the user in group B then show control B or possibly if the user is in group A don't include the control at all). Also, my model is very flat so I'm not sure the built-in ability to apply my ViewModel to a specific portion of the view will help. My solution to this problem is to provide an action in my controller that responds with an object in JSON format with that contains the JQuery selector and the content to assign to the "data-bind" attribute and bind the ViewModel to the View in the $(document).ready event using the values provided. Failed Proof-of-concept My first attempt at proving that this works doesn't actually seem to work, and by "doesn't work" I mean it just doesn't bind the values at all (as can be seen in this jsfiddle). I've tried it with the applyBindings inside of the ready event and not, but it doesn't seem to make any bit of difference. Question What am I doing wrong? Or is this just not something that can work with KO (though I've seen at least one example online doing the same thing and it supposedly works)? Like I said in the preface, I've only ever pretended to be a JS developer (though I've generally gotten it to work in the past) so I'm at a loss where to start trying to figure out what I'm doing wrong. Hopefully this isn't a real noob question.
