我正在尝试创建代码,首先创建数据库。我有2个连接字符串:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=DESKTOP-1111\SERVER_2014; database=the_userdb;user=sa; password=myPassword" providerName="System.Data.SqlClient" />
<add name="PmisDatabaseContext" connectionString="Data Source=DESKTOP-1111\SERVER_2014; database=the_database;user=sa; password=myPassword" providerName="System.Data.SqlClient" />
</connectionStrings>
起初,我可以使用此功能添加迁移:
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public bool IsActivated { get; set; }
public DateTime EnrollDate { get; set; }
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{ }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
//AspNetUsers -> User
modelBuilder.Entity<ApplicationUser>()
.ToTable("User");
//AspNetRoles -> Role
modelBuilder.Entity<IdentityRole>()
.ToTable("Role");
//AspNetUserRoles -> UserRole
modelBuilder.Entity<IdentityUserRole>()
.ToTable("UserRole");
//AspNetUserClaims -> UserClaim
modelBuilder.Entity<IdentityUserClaim>()
.ToTable("UserClaim");
//AspNetUserLogins -> UserLogin
modelBuilder.Entity<IdentityUserLogin>()
.ToTable("UserLogin");
}
}
然后我'启用了迁移'然后'添加迁移InitialDatabase'然后'update-database'并且能够成功创建一个包含登录表的新数据库。
现在我想用一个名为ImageLibraries的表创建一个新数据库,所以我在我的模型中这样做了:
[Table("ImageLibrary")]
public class ImageLibrary
{
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Key]
public int Id { get; set; }
[Required]
public string UserId { get; set; }
}
然后补充说:
public class PmisDatabaseContext : DbContext
{
public PmisDatabaseContext()
: base("name=PmisDatabaseContext")
{
Database.SetInitializer<PmisDatabaseContext>(new CreateDatabaseIfNotExists<PmisDatabaseContext>());
}
public virtual DbSet<ImageLibrary> ImageLibraries { get; set; }
}
当我尝试'添加迁移AddedImageLibrary'时,在我的迁移文件夹中,我得到'up()'和'down()',但没有任何内容。它不是创建新的数据库和表。你能告诉我如何做到这一点。谢谢。
