  • Problem with displaying content when using RJS

    - by Shreyas Satish
    I'm quite sure this is a silly error but I'm unable to spot it. Please help me out on this. This is my controller code def filter_by_content @articles = Article.find(:all) end My RJS (filter_by_content.rjs) update_page do |page| page.replace_html 'articles', :partial => 'main/filtered', :object => @articles end My Partial 'filtered' <div id = "articles"> <% if @articles %> <% @articles.each do |article| %> <%= article.title %> <% end %> <% end %> </div> I checked my server, and the articles are sure getting fetched but the problem is with displaying them. Thanks !

  • What is a .NET managed module?

    - by Abhijeet Patel
    I know it's a Windows PE32, but I also know that the unit of deployment in .NET is an assembly which in turn has a manifest and can be made up of multiple managed modules. My questions are : 1) How would you create multiple managed modules when building a project such as a class lib or a console app etc. 2) Is there a way to specify this to the compiler(via the project properties for example) to partition your source code files into multiple managed modules. If so what is the benefit of doing so? 3)Can managed modules span assemblies? 4)Are separate file created on disk when the source code is compiled or are these created in memory and directly embedded in an assembly?

  • How to wrap LINQ to SQL queries in stored proc?

    - by Satish
    LINQ to SQL internally generates SQL queries and fire on the database after submitting changes. Is there any way we can wrap all these queries in some stored procedure and execute this store proc everytime when anything gets inserted or updated in the database. Problem is only stored procedures are allowed to carry any insert or update or delete operations, direct queries are restricted for security purpose.

  • LINQ Except operator and object equality

    - by Abhijeet Patel
    Here is an interesting issue I noticed when using the Except Operator: I have list of users from which I want to exclude some users: The list of users is coming from an XML file: The code goes like this: interface IUser { int ID { get; set; } string Name { get; set; } } class User: IUser { #region IUser Members public int ID { get; set; } public string Name { get; set; } #endregion public override string ToString() { return ID + ":" +Name; } public static IEnumerable<IUser> GetMatchingUsers(IEnumerable<IUser> users) { IEnumerable<IUser> localList = new List<User> { new User{ ID=4, Name="James"}, new User{ ID=5, Name="Tom"} }.OfType<IUser>(); var matches = from u in users join lu in localList on u.ID equals lu.ID select u; return matches; } } class Program { static void Main(string[] args) { XDocument doc = XDocument.Load("Users.xml"); IEnumerable<IUser> users = doc.Element("Users").Elements("User").Select (u => new User { ID = (int)u.Attribute("id"), Name = (string)u.Attribute("name") } ).OfType<IUser>(); //still a query, objects have not been materialized var matches = User.GetMatchingUsers(users); var excludes = users.Except(matches); // excludes should contain 6 users but here it contains 8 users } } When I call User.GetMatchingUsers(users) I get 2 matches as expected. The issue is that when I call users.Except(matches) The matching users are not being excluded at all! I am expecting 6 users ut "excludes" contains all 8 users instead. Since all I'm doing in GetMatchingUsers(IEnumerable users) is taking the IEnumerable and just returning the IUsers whose ID's match( 2 IUsers in this case), my understanding is that by default "Except" will use reference equality for comparing the objects to be excluded. Is this not how "Except" behaves? What is even more interesting is that if I materialize the objects using .ToList() and then get the matching users, and call "Except", everything works as expected! Like so: IEnumerable users = doc.Element("Users").Elements("User").Select (u = new User { ID = (int)u.Attribute("id"), Name = (string)u.Attribute("name") } ).OfType().ToList(); //explicity materializing all objects by calling ToList() var matches = User.GetMatchingUsers(users); var excludes = users.Except(matches); // excludes now contains 6 users as expected I don't see why I should need to materialize objects for calling "Except" given that its defined on IEnumerable? Any suggesstions / insights would be much appreciated.

  • What are Sharepoint(MOSS 2007) Developement/Deployment best practices.

    - by Satish
    We are deploying sharepoint MOSS 2007 at our work. I'm trying to come up with a sharepoint development and deployment methodology. We have Dev/QA/Prod environments and I need a way, preferably automated to deploy changes from Dev to QA and from there to prod. We are creating site collections web parts etc. Some of it is done directly within sharepoint, some through Sharepoint designer or visual studio. I'm looking for a way to extract this and deploy it to other enviornments. I tried stsadm backup/restore import/export etc but they all move the data along with it as well. I just need the structure deployed. Content deployment paths and jobs does the same thing as well. We use MSBuild & Curisecontrol.net for other .net projects to automate build/deployment process. I'm looking for something similar with sharepoint if possible. What are your best practices for this? Since my team is learning we don't have a defined process and we are open to change our development process if needed.

  • GWT-RPC vs HTTP Call - which is better??

    - by Nirmal Patel
    I am evaluating if there is a performance variation between calls made using GWT-RPC and HTTP Call. My appln services are hosted as Java servlets and I am currently using HTTPProxy connections to fetch data from them. I am looking to convert them to GWT-RPC calls if that brings in performance improvement. I would like to know about pros/cons of each... Also any suggestions on tools to measure performance of Async calls...

  • How do i plot a vertical axis with variable intervals (Flex Charts or any other)

    - by satish
    How do i plot a vertical axis with variable intervals? on a Flex Chart. I want to plot a data set that has values from 0.1 to 800. When I use a standard Numerical Axis, I have to define a interval. I tried using Log-Axis, but I am not sure how to plot the point values. Looks like something in lines of semi-log axis would be better. A axis with initial values in Numerical, but later shifting gears to a Log-Axis. Any ideas or pointers to implement this in Flex?
