推荐答案

尝试一下:

class MemberOwner extends Eloquent {

public function members()
{
    return $this->belongsToMany('Member','MemberOwner_Member','foreign key','localkey');
  }
}

在这里，我们在MemberOwner模型中指定此名称，对于MemberOwner_Member表，外键将是ownerid，如果要指定本地ID，则它将是那里的主键id. 使用这个:

Here we are specifying this in MemberOwner model and for MemberOwner_Member table foreign key would be ownerid and if you want to specify local id then it would be id which is primary key there. Use this:

 class MemberOwner extends Eloquent {

   public function members()
   {
    return $this->belongsToMany('Member','MemberOwner_Member','ownerid');
  }
}

如果您要指定本地密钥，这也将起作用.

And this will work also if you want to specify local key.

 class MemberOwner extends Eloquent {

    public function members()
   {
      return $this->belongsToMany('Member','MemberOwner_Member','ownerid','id');
   }
}
