MVC5+EF6+AutoMapper+Bootstrap打造在线博客（1.1）

DAL层的三个Model类：

字典表：CFDict

用户表：CFUser

用户爱好表：CFUserHobby(关联cfuser表和cfdict表)

CFUser表和CFUserHobby表是一对多关系，一个用户有多个爱好，CFDict表和CFUserHobby表是一对多关系，某一个爱好可能很多人都有

public class CFDict
{
//标识列
public int Id { get; set; }

//名称
public string Name { get; set; }

//父ID
public int ParentId { get; set; }

//所在层，从0开始
public int Level { get; set; }

//所属分类
public string Category { get; set; }

//排序号
public int? OrderNum { get; set; }

public virtual ICollection<CFUserHobby> CFUserHobbys { get; set; }
}

public class CFUser
{
public int Id { get; set; }

//用户名
[StringLength(50)]
public string UserName { get; set; }

//密码

public virtual ICollection<CFUserHobby> CFUserHobbys { get; set; }
}

public class CFUserHobby
{
//标识列
public int Id { get; set; }

//用户ID
public int CFUserId { get; set; }

//爱好ID
public int CFDictId { get; set; }

public virtual CFUser CFUser { get; set; }

public virtual CFDict CFDict { get; set; }
}

public class CFContext : DbContext
{
public CFContext()
: base("CFContext")
{
}

public DbSet<CFUser> CFUsers { get; set; }

public DbSet<CFDict> CFDicts { get; set; }

public DbSet<CFUserHobby> CFUserHobbys { get; set; }

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

base.OnModelCreating(modelBuilder);
}
}
