Glad you got it working.   The ibmmx should automatically regenerate if any part of the model changes, including the DbContext, so we'll follow up on that to see if there's a problem.]]> Sun, 03 Feb 2013 08:51:37 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15776#15776 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15774#15774 Author: gregweb

Thanks Kim. Once I deleted the ibmmx file and let it regenerate, it started working. I think the issue was that I added the DbContext after the original ibmmx file was generated, so that data was missing from it.

Do you have a custom IDataSourceKeyResolver?  I'm assuming not, but if so, check what it's doing.  Also check that the .ibmmx is marked as an embedded resource.  And finally, the debug log may have additional information on the processing preceding this error, and may prove helpful.]]> Sat, 02 Feb 2013 18:19:28 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15773#15773 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15771#15771 Author: gregweb

OK, checked that, and the connection string is in web.config as well:

<add name="SecurityEntities" connectionString="Data Source=.;Initial Catalog=Jet31;Integrated Security= True;MultipleActiveResultSets=True;App=Jet" providerName="System.Data.SqlClient" />

But it still throws the same error.

At runtime, DevForce will look for the connection string in the web.config, or the app.config if a 2-tier Windows/WPF app.  So make sure the connection string in your Security project is also in a config used at runtime.]]> Sat, 02 Feb 2013 14:15:56 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15770#15770 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15769#15769 Author: gregweb

I have a Cocktail app set up using the same security structure as TempHire except I am using SQL Server.

When the LogInManager.Login() runs, it throws the error "No datasource key found for this entity type: Security.User.

Yet the datasource key appears to be set up correctly:

In the Security project, there is a App.Config with a connection string name "SecurityEntities" is configured.

The SecurityDBContext has a DataSourceKey attribute set to "SecurityEntities"

When I build the project the Build output shows the connection string is found:

Creating metadata from EntityManager 'SecurityEntities'
1> Searching for connectionString named 'SecurityEntities': found
1> Model metadata created for SecurityEntities
1> Model metadata for SecurityEntities.ibmmx is unchanged

The server log says: LoginException: Unable to login: No datasource key found for this entity type: Security.User

I am not sure what else to look for to resolve.]]> Sat, 02 Feb 2013 14:06:22 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3969&PID=15769#15769
