[英]How i can create custom user and role with ASP.NET Core identity v preview 3.0?
创建迁移文件时,出现错误,如下所示:
System.InvalidOperationException: Cannot create a DbSet for 'IdentityRole' because this type is not included in the model for the context.
System.InvalidOperationException: Cannot create a DbSet for 'UserApp' because this type is not included in the model for the context.
是的,我的上下文中没有此列,但是在以前的版本中,没有这些列就可以工作。 我的代码是:
public class UserApp: IdentityUser
{
[PersonalData]
public int Year { get; set; }
[PersonalData]
public string Country { get; set; }
public List<Product> products { get; set; }
}
和上下文类:
public class ApplicationContext:DbContext
{
public ApplicationContext()
{
}
//public ApplicationContext(DbContextOptions options) : base(options) { }
public ApplicationContext(DbContextOptions<ApplicationContext> dbContext) : base(dbContext)
{
}
与一些dbset。 在启动课程中,我有:
services.AddIdentity<UserApp, IdentityRole>(o =>
{
o.Password.RequireDigit = false;
o.Password.RequireLowercase = false;
o.Password.RequireUppercase = false;
o.Password.RequireNonAlphanumeric = false;
o.Password.RequiredLength = 6;
})
.AddEntityFrameworkStores<ApplicationContext>()
.AddDefaultTokenProviders();
怎么了? 真的在这个版本中,我必须在上下文中添加用户和角色的属性吗?
问题是您的ApplicationContext
继承了DbContext
而不是IdentityDbContext
。 因此,您的ApplicationContext
应该如下所示:
public class ApplicationContext : IdentityDbContext<UserApp, IdentityRole, string>
{
public ApplicationContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
}
}
