MVC :: Creating Table Records With Foreign Key Constraints / Separate Controllers?

Oct 3, 2010

I have multiple tables that are all linked back to a central table with foreign keys. I want to be able to create a new record in table 2, but I'm having trouble because I don't know how to create a new instance of table 2's record while referencing the ID of the record it will be tied to.

EXAMPLE:

Database: Collection
Table: Collection Field 1: id Field 2: name
Table: Book Field 1: collectionId Field 2: id Field 3: name

Now, I don't want to be able to create a book without setting it's collectionID, but I can't figure out how this should be divided in the controllers/views.

Should Book have a controller separate from Collection, or should the Collection controller have a createBook method, separate from it's own create method?

I want to call the createBook method (from it's own controller, or the Collection controller) from the Collection Details view.

When I invoke the create method of Book, how do I create a new Book that is instantiated with the collectionId set from the details view of the Collection item that was listed in the details view?

I should point out, I'm using the entity framework for my model, and I'm definitely new to this.

Creating Separate Models And Controllers Projects

Jan 22, 2011

I am reorganizing my MVC app into a Models project and a Controllers project, and then the main application as a project. So, everything is working good so far except. Whenever I go to "Rebuild" my controllers project, I get this error:
Controllers.AccountController.Initialize(System.Web.Routing.RequestContext)': no suitable method found to override.

Keep in mind that AccountController.cs was automatically placed in my application by Visual Studio, and this was all working fine when the Controllers were within my main project. I think it might have to do with the ASPNETDB.MDF file that this AccountController.cs file references to authenticate users as they log in, since this database stayed within my main project and didn't follow the Controllers project.

Here's the Initialize method on my AccountController:
protected override void Initialize(RequestContext requestContext) {
if (FormsService == null) { FormsService = new FormsAuthenticationService(); }
if (MembershipService == null) { MembershipService = new AccountMembershipService(); }
base.Initialize(requestContext); }

MVC :: Storing Controllers & Views In Separate Assemblies?

Apr 14, 2010

I'm building a CMS type of application in MVC. I want to reuse my views and controllers for adding/managing content in at least two other MVC sites. Obviously I dont want more than one code base for the CMS stuff. I figured out a way to do so:

Controllers:

Controllers are easy. Nothing more than creating a new Class Library Project and adding your controllers. Be sure to reference System.Web.MVC. In your MVC project just reference your controller assembly.

Views:

Views are a bit trickier. My solution was to add the folder structure to my assembly

CMSViews
CMSViewsWhatever

Then start adding my view pages. For each page, you have to set the 'Copy to Output Directory' to 'Copy Always' (right click -> properties)

Then I created a new class which inherits from 'WebFormViewEngine'. In the constructor I call the base() and then I add paths to the base.MasterLocationFormats and base.ViewLocationFormats to specify the new locations to look for views.

[Code]....

Setup in MVC project:

To get the controllers and views to work from the assemblies, you have to add two lines of code in the global.asax. Under the RegisterRoutes() method, add

ControllerBuilder.Current.DefaultNamespaces.Add("YourAssemblyNamespace.Controllers");
then under the Application_Start() method add:
ViewEngines.Engines.Add(new YourAssemblyNamespace.MyViewEngine());

What I dont like is that the Views get put into the Bin directory when published and you have to make sure to set the Ouput to Copy Always which is going to be a PITA for larger projects with lots of views.

MVC :: Linq And C# Update Foreign Table

Add A Foreign Key From A Table In Another Database Connection?

Jan 21, 2011

I have set up a ASP.net MVC application which uses the default forms authentication. It uses the ASPNETDB.mdf like shown here:

I then set up another database connection which is similar to the NerdDinner.mdf file above.

I have a post that belongs to a user. It has a UserId value which needs to be a foreign key to the information in ASPNETDB.mdf. When I go to add a foreign key, I can only see information with regards to the table I made. How do I go about doing this?

Dynamic Data Foreign Key Table Display Name?

Nov 26, 2010

I have these two tables in my diagram:

the 1st:
PAR_TipiDocumento with
idTipoDocumento PK
idClasseDocumento
[...]

the 2nd:
PAR_ClassiDocumento with
idClasseDocumento PK
[...]

and a foreing key FK_PAR_TipiDocumento_PAR_ClassiDocumento from PAR_TipiDocumento.idClasseDocumentoto PAR_ClassiDocumento.idClasseDocumento.

This is my .cs code for the metadata:

[MetadataType(typeof(PAR_TipiDocumento_Metadata))]
[DisplayName("Tipi Documento")]
public partial class PAR_TipiDocumento[code]....

The problem is that in the Dynamic Data generated pages I correctly see all the display names "Tipi Documento" except for the header row of the PAR_ClassiDocumento table where I have "PAR_TipiDocumentos" (the plural generated by LINQ to SQL). The values under this column are correctly rendered as links to the PAR_TipiDocumento table with the right display name ("View Tipi Documento").

How can I change the Display Name of that "PAR_TipiDocumentos"?
