在查找了几分钟以了解为什么我的数据库没有播种后,我在 we.config 文件中发现了以下消息。
完整的消息列表如下:
消息 1 找不到元素“entityFramework”的架构信息。
消息 2 找不到元素“defaultConnectionFactory”的架构信息。
消息 3 找不到 at'type' 的架构信息。
现在我对 MVC 非常陌生,这是我构建的第一个应用程序。我想利用可用的 Code First 技术从我构建的模型中创建数据库。
这是我创建的模型的示例:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations.Schema;
using System.ComponentModel;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations;
namespace TNTMVC.Models.UECDECZA.BaseTables
{
public class Actions
{
[Key]
public int ActionID { get; set; }
[Timestamp]
public DateTime ActionDateCreated { get; set; }
[Required]
[DefaultValue(true)]
public bool ActionActive { get; set; }
[Required]
public string ActionName { get; set; }
[Required]
[DefaultValue(true)]
public bool ActionRequiresComponents { get; set; }
[Required]
[DefaultValue(1000)]
public int ActionListOrder { get; set; }
}
}
然后我创建了我的数据库上下文类,看起来像这样。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;
using TNTMVC.Models.UECDECZA.BaseTables;
using TNTMVC.Models.UECDECZA.DataTables;
namespace TNTMVC.Models.UECDECZA
{
public class UecdeczaContext : DbContext
{
public DbSet<Actions> Actions { get; set; }
public DbSet<Application> Application { get; set; }
public DbSet<Area> Area { get; set; }
}
}
这是我的 Web.Config 文件:
<?xml version="1.0" encoding="utf-8"?>

这应该是一个成功的模型实现吧?但它似乎根本不起作用。它没有播种我的数据库,也没有工作:(
我也在 ASP 论坛上问过同样的问题:我的 ASP 论坛问题
