alredy 기존 데이터베이스에서 내 seed 메소드를 실행할 수 없습니다. 이 데이터베이스는 다중 마이그레이션의 결과로, 우리가 만든 데이터베이스 "Whitelabel"을 ASP.NET MVC5 Identity 데이터베이스 ("IdentityDb"라고 함)와 함께 마이그레이션했습니다. 여기 update-database fires : "이미 데이터베이스에 'Adresses'라는 개체가 있습니다."
데이터베이스 테이블의 개요입니다 :PM> update-database -ConfigurationTypeName DAL.DataContexts.WhitelabelMigrations.Configuration
:
이 코드 첫째되어 있기 때문에,이 명령을 사용하여 데이터베이스를 업데이트하기 위해 패키지 관리자 콘솔을 사용 그리고 그것은 "데이터베이스에 이미 'Adresses'라는 개체가 있습니다."라는 오류가 발생합니다.
여기 WhitelabelDb 컨텍스트가 있습니다.
using ClassLibrary.Entities;
using Microsoft.AspNet.Identity.EntityFramework;
namespace DAL.DataContexts
{
public class IdentityDb : IdentityDbContext<ApplicationUser>
{
public IdentityDb()
: base("WhitelabelDb")
{
}
}
}
여기 WhitelabelMigrations에 대한 configuration.cs 파일입니다 :
using System.Data.Entity.Migrations;
using System;
using System.Collections.ObjectModel;
using System.Data.Entity.Migrations;
using System.Linq;
using ClassLibrary.Entities;
namespace DAL.DataContexts.WhitelabelMigrations
{
internal sealed class Configuration : DbMigrationsConfiguration<WhitelabelDb>
{
public Configuration()
{
AutomaticMigrationsEnabled = true;
MigrationsDirectory = @"DataContexts\WhitelabelMigrations";
}
protected override void Seed(WhitelabelDb context)
{
**//This is the seed method I want to run when I update the database:**
if(!context.CategorySet.Any(c => c.Name == "Root"))
{
Category mainCategory = new Category { Id = Guid.NewGuid(), Name = "Root", Parent = null };
context.CategorySet.Add(mainCategory);
context.SaveChanges();
}
}
}
}
가 그리고 InitialCreate.cs 시스템을 사용하여 WhitelabelMigrations 신청을
using System.Data.Entity;
using ClassLibrary.Entities;
namespace DAL.DataContexts
{
public class WhitelabelDb : DbContext
{
public WhitelabelDb()
: base("WhitelabelDb")

public virtual DbSet<Category> CategorySet { get; set; }
public virtual DbSet<Product> ProductSet { get; set; }

public virtual DbSet<Invoice> InvoiceSet { get; set; }
public virtual DbSet<Customer> CustomerSet { get; set; }
public virtual DbSet<Adress> AdressSet { get; set; }

, 나는에만 허용 목록 라벨 configuration.cs 파일에서 Category 클래스에 액세스 할 수 있기 때문에 실행 씨앗 방법을 얻을 수있는 방법 ?
설명, 생각 및 건설적인 도움을 주시면 감사하겠습니다.
public virtual DbSet<Category> CategorySet { get; set; }
의 I는 IdentityMigrations의 configuration.cs의 범주 클래스에 액세스 할 수 있습니다 그리고 그 길을 나는 작업 내 종자 방법을 만듭니다
