根据 Laravel 的文档在我创建的模型中创建关系时出现了我的问题。我有我的区号表和我的电话表,一个区号可以属于多部电话,但一部电话只有一个区号,这使我成为一对多的关系我将向您展示我的模型和它们之间的关系。电话.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');} 区号.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 $this->hasMany('App\Phone');}在我的控制器中,调用如下GenerateNumbersController.php$phones = Phone::where('DATE',$searchOrCreate) ->chunk(500,function($phone){ foreach ($phone as $p) { dd($p->areacodes); } });searchOrCreate 变量有一个日期格式的值,我对 $ phone 做了一个 dd 并且它显示的所有关系都是空的
