使用Entity Framework的ASP.NET MVC 4项目未从sampledata填充数据库

Question

I'm working on a project and have had a terrible time getting my database to populate data from my SampleData.cs code. I saw another article explain on how to create the database, which worked, but the database still won't populate with code.

Here is my Global.asax page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using System.Data.Entity;
using RickFinalProject.Models;

namespace RickFinalProject
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode, 
// visit http://go.microsoft.com/?LinkId=9394801

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        Database.SetInitializer(new SampleData());


        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
    }
}
}

My Web.Config page

My SampleData.cs page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace RickFinalProject.Models
{
//public class SampleData : CreateDatabaseIfNotExists<RickFinalProjectDBContext>
public class SampleData : DropCreateDatabaseIfModelChanges<RickFinalProjectDBContext>
{
    protected override void Seed(RickFinalProjectDBContext context)
    {

        var expansions = new List<Expansion>
        {
            new Expansion { ExpansionName = "Ravnica" },
            new Expansion { ExpansionName = "Mirrodin" },
            new Expansion { ExpansionName = "Saviors of Kamigawa" }
        };

        new List<Card>
        {
            new Card { CardName = "Platinum Angel", Expansion = expansions.Single(a => a.ExpansionName == "Mirrodin"), Rarity = "Rare", Color = "Colorless", Cost = 7, Type = "Artifact Creature",  Wording = "Flying, You can't lose the game and your opponents can't win the game." },
            new Card { CardName = "Char", Expansion = expansions.Single(a => a.ExpansionName == "Ravnica"), Rarity = "Rare", Color = "Red", Cost = 4, Type = "Instant",  Wording = "Char deals 4 damage to target creature or player and 2 damage to you." },
            new Card { CardName = "Twincast", Expansion = expansions.Single(a => a.ExpansionName == "Saviors of Kamigawa"), Rarity = "Rare", Color = "Blue", Cost = 2, Type = "Instant",  Wording = "Copy target instant or sorcery spell. You may choose new targets for that spell." }

        }.ForEach(a => context.Cards.Add(a));
    }
}
}

I'm really lost because it seems like this has worked on other projects I've seen and done. Any help will be much appreciated. Thank you.

Edit 1: There are no errors. The database simply isn't populating the data. I did a select * from Card; and it was empty. The SampleData.cs should add data to the database... right?

Answer 1

Sorry can't comment,

1. Are you sure you are checking the correct DB for the changes? You have 2 connection strings.

2. Put a SaveChanges at the end of Seed and see if you get anything useful.

3. Debug Seed

   if (System.Diagnostics.Debugger.IsAttached == false) System.Diagnostics.Debugger.Launch();
