和完成一樣：

1. 創(chuàng)建 MVC
2. 選擇Individual User
3. 建立 base model

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Craglist.Models
{
    public class Category : Hideable
    {
        public virtual ICollection<Subcategory> Subcategories { get; set; }
    }

    public class Subcategory : Hideable
    {
        public virtual Category Category { get; set; }
        public virtual ICollection<Post> Posts { get; set; }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Craglist.Models
{
    public class Post
    {
        public int Id { get; set; }
        public DateTime Timestamp { get; set; }
        public DateTime Expiration { get; set; }
        public virtual User Owner { get; set; }
        public String Title { get; set; }
        public String Body { get; set; }
        public virtual Locale Locale { get; set; }
        public virtual Subcategory Subcategory { get; set; }
    }
}

• PK id
• 發(fā)帖 時間
• 過期 時間
• 用戶 用戶類型
• 發(fā)帖 標(biāo)題
• Body 發(fā)帖內(nèi)容
• 發(fā)帖 地點 地點屬性
• 發(fā)帖 分類 子類型屬性

namespace Craglist.Models
{
    public class User
    {
        public String Id { get; set; }
        public String Email { get; set; }
        public Boolean IsAdmin { get; set; }
    }
}

• 用戶 ID String
• 用戶 郵箱 String
• 用戶 管理員屬性 Boolean

namespace Craglist.Models
{
    public class Category : Hideable
    {
        public virtual ICollection<Subcategory> Subcategories { get; set; }
    }

    public class Subcategory : Hideable
    {
        public virtual Category Category { get; set; }
        public virtual ICollection<Post> Posts { get; set; }
    }
}
