• Empathy auto accept group chat invite

  - by Sivaji

  I'm using empathy 2.34.0 as chat client for account hosted on Google app (server talk.google.com). I'm happy with the features that empathy provides and integration with Google chat, however for group chat when the request is received I need to click on "join" button showed in popup to get started. This makes sense but I would to know if there is any way to automatically join the chat room without clicking the "join" button as I use it only with trusted uses. Besides the messages shared after the invite request and before my entry to chat room is not accessible to me. I looked around the empathy settings but couldn't find anything useful, wondering if I can get some help from here. Thanks.

• Permissions scheme not working

  - by ReaZem

  I am currently building a home server and I am trying to give minimal permissions to every service. I am new to permissions management and this is an awesome learning experience for me :). drwxr----- 7 reazem enter-home 4096 Sep 9 21:43 reazem drwxrws--- 3 reazem minidlna 4096 Sep 9 21:36 media reazem is my home folder and media is my media folder, it is situated directly inside my home. The minidlna user is part of the following groups : minidlna, enter-home. I get the following error: Media directory not accessible! [/home/reazem/media] I was hoping that because the minidlna user is part of the enter-home group, it could get inside the home folder, and then inside the media folder because it is in the minidlna group. Where is my mistake? Edit: I found out that chmod g+x /home/reazem solved the problem, but why? Why would you need the execute permission to get inside another directory? Thank you!

  I have a standard template "ASP.NET MVC 2 Web application" solution, an empty (meaning no data inserted, but with all tables etc. ready and waiting) SQL Server database, an Entity Framework 4 model (edmx). Is there a way to generate simple CRUD controllers and form views for all the entities in the model?

• does Entity Framework have a caching mechanism like DataSet/DataTables have?

  - by Greg

  Hi, does Entity Framework have a caching mechanism like DataSet/DataTables have? In other words if you start using EF is it really just a way to easily get data in/out of the database without providing an additional caching layer like DataSet/DataTables did where you have an in-memory representation (on-line/off-line) and which at some point you could say to "persist all changes to database"

  Hi, whats the shortest way of returning an Entity Framework object from one table based on it's name attribute? So say one had a table person, with column name, what would be the quickest way to return the person object with name = "Tim" say? e.g. context.People.Select(m = m.Name == "Tim") doesn't seem to work?

• How do I get the entity framework to work with archive flags?

  - by Orion Adrian

  I'm trying to create a set of tables where we don't actually delete them, but rather we set the archive flags instead. When we delete an entity, it shouldn't be deleted, it should be marked as archived instead. What are the programming patterns to support this? I would also prefer not to have to roll out my own stored procs for every table that have these archive flags if there is another solution.

• How to override Equals on a object created by an Entity Data Model?

  - by jamone

  I have an Entity Data Model that I have created, and its pulling in records from a SQLite DB. One of the Tables is People, I want to override the person.Equals() method but I'm unsure where to go to make such a change since the Person object is auto-generated and I don't even see where that autogen code resides. I know how to override Equals on a hand made object, its just where to do that on an autogen one.

• Is it possible to dynamically discover tables in an Entity Framework model ?

  - by Scott Davies

  Hi, I have co-workers working on an Entity Framework model that changes structure (entities), over time as software development progresses. I've written some utilities that interact with the tables within the model, but I'd like to have the code dynamically discover the tables. Is there a way I can do this ? Perhaps with ADO.NET to get the table names and then store them in a collection ? Thanks, Scott

• How do I use Entity Framework in a CLR stored procedure?

  - by Ivan

  I am looking forward to move all the logic (which is implemented as manipulating Entity Framework 4 objects) to a server side. It looks going to be simple (thanks to the application structure) and beneficial (as all I have is one oldy laptop as a client and one tough server which runs SQL Server 2008, and building a separate service for the logic can just introduce more latency if compared to doing it inside the database). So how do I correctly use Entities Framework inside a CLR stored procedure and make it using a host-server-provided SqlContext?

• Using Entity Framework 4.0 with Code-First and POCO: How to Get Parent Object with All its Children

  - by SirEel

  I'm new to EF 4.0, so maybe this is an easy question. I've got VS2010 RC and the latest EF CTP. I'm trying to implement the "Foreign Keys" code-first example on the EF Team's Design Blog, http://blogs.msdn.com/efdesign/archive/2009/10/12/code-only-further-enhancements.aspx. public class Customer { public int Id { get; set; public string CustomerDescription { get; set; public IList<PurchaseOrder> PurchaseOrders { get; set; } } public class PurchaseOrder { public int Id { get; set; } public int CustomerId { get; set; } public Customer Customer { get; set; } public DateTime DateReceived { get; set; } } public class MyContext : ObjectContext { public RepositoryContext(EntityConnection connection) : base(connection){} public IObjectSet<Customer> Customers { get {return base.CreateObjectSet<Customer>();} } } I use a ContextBuilder to configure MyContext: { var builder = new ContextBuilder<MyContext>(); var customerConfig = _builder.Entity<Customer>(); customerConfig.Property(c => c.Id).IsIdentity(); var poConfig = _builder.Entity<PurchaseOrder>(); poConfig.Property(po => po.Id).IsIdentity(); poConfig.Relationship(po => po.Customer) .FromProperty(c => c.PurchaseOrders) .HasConstraint((po, c) => po.CustomerId == c.Id); ... } This works correctly when I'm adding new Customers, but not when I try to retrieve existing Customers. This code successfully saves a new Customer and all its child PurchaseOrders: using (var context = builder.Create(connection)) { context.Customers.AddObject(customer); context.SaveChanges(); } But this code only retrieves Customer objects; their PurchaseOrders lists are always empty. using (var context = _builder.Create(_conn)) { var customers = context.Customers.ToList(); } What else do I need to do to the ContextBuilder to make MyContext always retrieve all the PurchaseOrders with each Customer?
