我有两个模型:用户和消息。它们以一对多关系绑定在一起(一个用户可以发送许多消息)。表用户具有“电子邮件”列,表消息具有“ r_email”列(这是同一字段)。因此,我需要进行如下查询:“ SELECT * FROM Users,消息WHERE Users.email = Message.r_email。我该怎么做?
我尝试过这样的事情:
$messages = App\Message::with('users')->where('users.email', '=', 'messages.r_email')->get();
但是它给了我错误。有什么问题吗?
以这种方式绑定模型:
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
public function messages()
{
return $this->hasMany(Message::class);
}
}
以及消息模型的代码:
class Message extends Model
{
protected $fillable = ['message', 'r_email'];
public function user()
{
return $this->belongsTo(User::class);
}
}

.then(res=>res.json())
.then(data=>{
if(data){
this.setState.({editorHtml : data});
}
}).catch(ex){
//handle error here
}
希望获得帮助。
