Question

我按照tutorial编写了种子方法。我认为我的web.config文件连接有问题，但我无法弄明白。如果有人可以帮助我，我会很高兴。

FilmNetworkContext.cs

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

namespace FilmNetwork.Models
{
public class FilmNetworkContext : DbContext
{
    public FilmNetworkContext() : base("FilmNetworkContext")
        {
        Database.SetInitializer<FilmNetworkContext>(new CreateDatabaseIfNotExists<FilmNetworkContext>());

    }



    public DbSet<Director> Directors { get; set; }

    public DbSet<Film> Films { get; set; }

    public DbSet<Producer> Producers { get; set; }

    public DbSet<Genre> Genres { get; set; }
}
}

FilmNetworkInitializer.cs

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

namespace FilmNetwork.Models
{
public class FilmNetworkInitializer :     System.Data.Entity.DropCreateDatabaseIfModelChanges<FilmNetworkContext>
{
    protected override void Seed(FilmNetworkContext context)
    {
        var directors = new List<Director>
        {
            new Director {fName="Christopher",lName="Nolan",Age=46},
            new Director {fName="David", lName="Fincher",Age=54 },
            new Director {fName="Jason", lName="Reitman",Age=39 },
            new Director {fName="Danny", lName="Boyle",Age=60 },
            new Director {fName="Martin", lName="Scorsese",Age=74 },
            new Director {fName="Peter", lName="Jackson",Age=55 },
            new Director {fName="Steven", lName="Spielberg",Age=70},
            new Director {fName="J.J", lName="Abrams",Age=50 },
            new Director {fName="Joel", lName="Coen",Age=62 },
            new Director {fName="James", lName="Cameron",Age=62 }
        };

        directors.ForEach(s => context.Directors.Add(s));
        context.SaveChanges();
    }
    }
    }

我有多套数据，我只是在这里展示一个。*

Answer 1

对于您设置标准初始值设定项的FilmNetworkContext：

Database.SetInitializer< FilmNetworkContext>(new CreateDatabaseIfNotExists< FilmNetworkContext>());

但您需要使用自定义初始值设定项：

Database.SetInitializer<FilmNetworkContext>(new FilmNetworkInitializer());
