Question

我几天前开始做一个新项目，并希望在我的项目中添加一个静态表来做到这一点我尝试使用Asp.net mvc上的种子，我已经为我添加了一个静态表已经存在的角色表，但是当我尝试为我创建的表种子时，它无法找到我的类的属性，在此示例中，描述会显示下划线，因为它无法找到它。

internal sealed class Configuration : DbMigrationsConfiguration<CrowdTouring2.Models.ApplicationDbContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = false;
        ContextKey = "CrowdTouring2.Models.ApplicationDbContext";
    }

    // Cria as tabelas estaticas no sistema
    protected override void Seed(CrowdTouring2.Models.ApplicationDbContext context)
    {
        if(!context.Roles.Any(r => r.Name == "Admin"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store);
            var role = new IdentityRole { Name = "Admin" };
            manager.Create(role);
        }

        if (!context.Roles.Any(r => r.Name == "Cliente"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store);
            var role = new IdentityRole { Name = "Cliente" };
            manager.Create(role);
        }

        if (!context.Roles.Any(r => r.Name == "Resolvedor"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store);
            var role = new IdentityRole { Name = "Resolvedor" };
            manager.Create(role);
        }

        if (!context.Roles.Any(r => r.Name == "Avaliador"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store);
            var role = new IdentityRole { Name = "Avaliador" };
            manager.Create(role);
        }

        var conta = new List<EstadoConta>
        {
            new EstadoConta { descricao = "Admin"}
        };


    }
}

我在身份模型上有我的dbSet，如下所示：

    using System.Data.Entity;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;

namespace CrowdTouring2.Models
{
    // You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/?LinkID=317594 to learn more.
    public class ApplicationUser : IdentityUser
    {
        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }
    }

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    public DbSet<EstadoConta> EstadosConta { get; set; }
}

}

我的班级

    namespace CrowdTouring2.Models
{
    public class EstadoConta
    {
        public int EstadoContaId { get; set; }
        public string descricao { get; set; }
    }
}

Answer 1

var conta = new List<EstadoConta>
    {
        new EstadoConta { descricao = "Admin"}  
 }; 
   conta.ForEach(s => context.contas.AddOrUpdate(p => p.descricao, s));
        context.SaveChanges();

无法为我的数据库播种
