我正在使用EF 6.1.1 当我在我的数据库上使用代码优先迁移时,它会向AspNetUserRoles表添加两个不需要的列:IdentityRole_Id,IdentityUser_Id 我见过这个RemoveFromRole cannot work as expected,但没有帮助我。
我该如何摆脱它们?
这是我的OnModelCreating
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
if (modelBuilder == null)
{
throw new ArgumentNullException("modelBuilder");
}
// Keep this:
modelBuilder.Entity<IdentityUser>().ToTable("AspNetUsers");
// Change TUser to ApplicationUser everywhere else -
// IdentityUser and ApplicationUser essentially 'share' the AspNetUsers Table in the database:
EntityTypeConfiguration<ApplicationUser> table =
modelBuilder.Entity<ApplicationUser>().ToTable("AspNetUsers");
table.Property((ApplicationUser u) => u.UserName).IsRequired();
// EF won't let us swap out IdentityUserRole for ApplicationUserRole here:
modelBuilder.Entity<ApplicationUser>().HasMany<IdentityUserRole>((ApplicationUser u) => u.Roles);
modelBuilder.Entity<IdentityUserRole>().HasKey((IdentityUserRole r) =>
new { UserId = r.UserId, RoleId = r.RoleId }).ToTable("AspNetUserRoles");
// Leave this alone:
EntityTypeConfiguration<IdentityUserLogin> entityTypeConfiguration =
modelBuilder.Entity<IdentityUserLogin>().HasKey((IdentityUserLogin l) =>
new
{
UserId = l.UserId,
LoginProvider = l.LoginProvider,
ProviderKey
= l.ProviderKey
}).ToTable("AspNetUserLogins");
//entityTypeConfiguration.HasRequired<IdentityUser>((IdentityUserLogin u) => u.User);
EntityTypeConfiguration<IdentityUserClaim> table1 = modelBuilder.Entity<IdentityUserClaim>().ToTable("AspNetUserClaims");
//table1.HasRequired<IdentityUser>((IdentityUserClaim u) => u.User);
// Add this, so that IdentityRole can share a table with ApplicationRole:
modelBuilder.Entity<IdentityRole>().ToTable("AspNetRoles");
// Change these from IdentityRole to ApplicationRole:
EntityTypeConfiguration<ApplicationRole> entityTypeConfiguration1 =
modelBuilder.Entity<ApplicationRole>().ToTable("AspNetRoles");
entityTypeConfiguration1.Property((ApplicationRole r) => r.Name).IsRequired();
}
它产生了这个:
CreateTable(
"dbo.AspNetUserRoles",
c => new
{
UserId = c.String(nullable: false, maxLength: 128),
RoleId = c.String(nullable: false, maxLength: 128),
IdentityRole_Id = c.String(maxLength: 128),
IdentityUser_Id = c.String(maxLength: 128),
})
.PrimaryKey(t => new { t.UserId, t.RoleId })
.ForeignKey("dbo.AspNetRoles", t => t.IdentityRole_Id)
.ForeignKey("dbo.AspNetUsers", t => t.IdentityUser_Id)
.Index(t => t.IdentityRole_Id)
.Index(t => t.IdentityUser_Id);
答案 0 :(得分:2)
假设您正在使用Identity EntityFramework(您的DbcontextClass:IdentityDbContext),那么我认为这一行是原因
modelBuilder.Entity<IdentityUserRole>().HasKey((IdentityUserRole r) =>
new { UserId = r.UserId, RoleId = r.RoleId }).ToTable("AspNetUserRoles");
OnModelCreating中的所有代码都将创建与默认相同的身份表(只要您的应用程序上下文类派生自IdentityDbContext<ApplicationUser>
如果您出于某种原因想要使用覆盖OnModelCreating,例如
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
然后你必须打电话给基地
base.OnModelCreating(modelBuilder);
