EF6 many-to-many table with additional date column

Question

I am using EF6 in database-first mode with a table User .

I want users to be able to share their profiles with other users by using delegation. For this, I defined a table UserDelegation with 2 columns : IdUser and IdDelegatedUser . Until here, everything is working as expected.

Now, I want to add a column for storing dates in the UserDelegation table. The problem is : I'm not able to call this property in my EF6 entities because the entity UserDelegation is not visible. Thus, I don't know where to look for my new property Date

I wonder if there is a way to resolve this problem or if this architecture is wrong ?

Answer 1

Here is what i got based on your description - You can try deleting the entity in the EDMX and try regenerating it.

My Interpretation of what you said:

DbContext

    public List<UserProfile> GetProfiles()
    {
        using (var ctx = new UserDatabaseEntities())
        {
            var ret = ctx.UserProfiles.Include("UserDelgations").Select(p => p).ToList();
            return ret;
        }
    }

SQL

CREATE TABLE [dbo].[UserDelgations] (
 [UserProfileId] UNIQUEIDENTIFIER NOT NULL CONSTRAINT FK_UserProfiles_UserProfileId FOREIGN KEY REFERENCES dbo.UserProfiles (Id) ON DELETE CASCADE,

[UserProfileDelgationId]            UNIQUEIDENTIFIER  NOT NULL,

[AuditDate]                         DATETIME NOT NULL default(getutcdate()),    


) Go 

ALTER TABLE [dbo].[UserDelgations] ADD CONSTRAINT PK_UserDelgations PRIMARY KEY ([UserProfileId] ASC, [UserProfileDelgationId] ASC) GO

CREATE TABLE [dbo].[UserProfiles] (
 Id uniqueidentifier NOT NULL constraint PK_UserProfiles primary key nonclustered (Id) constraint DF_UserProfiles_Id default(newid()),

UserName NVARCHAR(1024) NOT NULL,

CreatedBy          NVARCHAR(256) NOT NULL default(SYSTEM_USER),
CreatedDate        DATETIME NOT NULL default(getutcdate()), 


) Go
