我试图将多个模型绑定到一个窗体。目前,我有4种型号:通过另一个模型Laravel 4模型关系
<?php
class DemDataSet extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'DEMDataSet';
protected $primaryKey = 'pk_DEMDataSet';
public function DemographicReport(){
return $this->hasOne('DemographicReport','fk_DemDataSet','pk_DemDataSet');
}
}
class DemographicReport extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'DemographicReport';
protected $primaryKey = 'pk_DemographicReport';
public function DemDataSet(){
return $this->belongsTo('DemDataSet','fk_DemDataSet','pk_DemDataSet');
}
public function dAgency(){
return $this->hasOne('dAgency','fk_DemographicReport','pk_DemographicReport');
}
}
class dAgency extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'dAgency';
protected $primaryKey = 'pk_dAgency';
public function DemographicReport(){
return $this->belongsTo('DemographicReport','fk_DemographicReport','pk_DemographicReport');
}
public function dAgency_10(){
return $this->hasMany('dAgency_10','fk_dAgency','pk_dAgency');
}
}
class dAgency_10 extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'dAgency_10';
protected $primaryKey = 'pk_dAgency_10';
public function dAgency(){
return $this->belongsTo('dAgency','fk_dAgency','pk_dAgency');
}
}
?>
而且我将它传递给我的看法通过我的控制器,就像这样:
public function index()
{
//THIS is the line I need help with (I think):
$agency = dAgency::with('dAgency_10','DemographicReport')->find(1);
//for troubleshooting:
echo "<pre>",print_r(dAgency::with('dAgency_10','DemographicReport')->find(1)->toArray()),"</pre>";
return View::make('test')
->with('agency', $agency);
}
我能够绑定一切除了从DemDataSet模型数据,我甚至无法弄清楚如何建立它与我的模型之间的关系。所以基本上,我只想让DemviewSet模型中的字段可用于我的视图,然后显然我希望能够最终执行所有CRUD操作。
还不行。当我在我的控制器中调用'echo'
“;'时,我得到'[relations:protected] => Array([DemDataSet] =>)'表示DemDataSet为空。但是当我查看该模型的结果时('echo“ ”;'),它显然有数据。我仔细检查了我的hasOne()和belongsTo()他们看起来是否正确。 – jreed121'$ agency-> DemographicReport'是否具有'fk_DemDataSet'的值? – duellsy
是的,它的确如此。我的模特关系显然存在问题。我有一个类似的问题,这可能是同样的问题在这里:http://stackoverflow.com/questions/22165781/laravel-4-deleting-multiple-models-related-by-foreign-keys。在我真正考虑过这个问题的可能性之前,我做了这件事。谢谢你看看男人,我一直在殴打自己,我知道这可能很简单。 – jreed121
