根據(jù) Laravel 的文檔在我創(chuàng)建的模型中創(chuàng)建關(guān)系時(shí)出現(xiàn)了我的問(wèn)題。我有我的區(qū)號(hào)表和我的電話表，一個(gè)區(qū)號(hào)可以屬于多部電話，但一部電話只有一個(gè)區(qū)號(hào)，這使我成為一對(duì)多的關(guān)系我將向您展示我的模型和它們之間的關(guān)系。電話.php/** * The table associated with the model. *  * @var string * @author Luis Morales */protected $table = 'PHONES';/** * The primary key associated with the table. * * @var string * @author Luis Morales */protected $primaryKey = 'PHONES_ID';/** * The attributes that are mass assignable. * * @var array * @author Luis Morales */protected $fillable = [    'AREACODES_ID', 'PHONE', 'DATE', 'USERS_ID',];/** * Indicates if the model should be timestamped. * * @var bool * @author Luis Morales */public $timestamps = false;/** * Get the user for the phone *  * @author Luis Morales */public function users(){    return $this->belongsTo('App\User');}/** * Get the area code for the phone *  * @author Luis Morales */public function areacodes(){    return $this->belongsTo('App\AreaCode');}   區(qū)號(hào).php/** * The table associated with the model. *  * @var string * @author Luis Morales */protected $table = 'AREACODES';/** * The primary key associated with the table. * * @var string * @author Luis Morales */protected $primaryKey = 'AREACODES_ID';/** * The attributes that are mass assignable. * * @var array * @author Luis Morales */protected $fillable = [    'CODE', 'CITY', 'STATESZONE_ID',];/** * Indicates if the model should be timestamped. * * @var bool * @author Luis Morales */public $timestamps = false;/** * Get the phone for the area codes * * @author Luis Morales */public function phones(){    return $this->hasMany('App\Phone');}在我的控制器中，調(diào)用如下GenerateNumbersController.php$phones = Phone::where('DATE',$searchOrCreate)                ->chunk(500,function($phone){                        foreach ($phone as $p) {                        dd($p->areacodes);                    }        });searchOrCreate 變量有一個(gè)日期格式的值，我對(duì) $ phone 做了一個(gè) dd 并且它顯示的所有關(guān)系都是空的
