[英]ASP.net core 2.0 MVC every new database migrations includes data from previous migrations
[英]ASP.NET Core MVC - User Tables not being created when applying database migrations
我有一個 Asp.net Core MVC 項目,執行以下命令時沒有在數據庫中創建用戶表:
Add-Migration migrationName
Update-Database
它將更新我的模型鏈接到的表,但不會添加用戶表。 這是一個問題,因為我想使用 ASP.NET Core MVC 框架提供的登錄功能,我認為這些表應該在應用遷移時自動填充數據庫。
有誰知道為什么在通過 nugget 包管理器控制台更新我的數據庫時這不會自動發生? 這是我從 github 獲得的一個朋友的項目,我需要處理它,我不確定要檢查什么以確保他們正確配置了這個項目,以便自動創建用戶表。
如何配置我的項目以自動添加用戶表?
任何幫助將不勝感激 - 我已經看過以前的堆棧溢出答案,但大多數已經過時了。
編輯:數據庫中的遷移表確實包括我應用於數據庫的 userTest 遷移。 這里也是在 MVC 項目中創建的遷移文件,如果有幫助的話。:
using Microsoft.EntityFrameworkCore.Migrations;
namespace SEWebPage03.Migrations
{
public partial class userTest : Migration
{
protected override void Up(MigrationBuilder migrationBuilder)
{
}
protected override void Down(MigrationBuilder migrationBuilder)
{
}
}
}
如果您在創建項目時選擇了No Authentication
...您將需要手動搭建身份框架。
這是可以做到的……它需要幾個步驟。
首先是修改ApplicationDbContext.cs
改變這一行
public class ApplicationDbContext: DbContext {}
對此
public class ApplicationDbContext: IdentityDbContext {}
您將需要安裝這些 Nuget 包。
Microsoft.AspNetCore.Identity.EntityFrameworkCore
Microsoft.AspNetCore.Identity.UI
Next Change StartUp.cs
在ConfigureServices
添加:
services.AddDefaultIdentity<IdentityUser>()
.AddEntityFrameworkStores<ApplicationDbContext>();
使用它來添加角色
services.AddIdentity<IdentityUser,IdentityRole>()
.AddDefaultTokenProviders().AddDefaultUI()
.AddEntityFrameworkStores<ApplicationDbContext>();
現在在 StartUp.cs 中進一步向下滾動到 Configure 方法。
在app.UseAuthorization()
之前添加app.UseAuthentication();
重要..它需要按照這個順序。
app.UseAuthentication();
app.UseAuthorization();
現在你添加一個新的遷移
PM->add-migration scaffoldIdentity
PM->更新數據庫
身份遷移
