我正在尝试通过连接获取数据集,并且我想使用 eloquent 自动完成,无需手动查询。我也做了关系,但是当我尝试列出加入的数据时,它以某种方式做到了。
Laravel 5.7 版 MySQL 数据库
错误:
“SQLSTATE [42S22]:未找到列:1054 'where 子句'中的未知列'myTab1.my_tab3_id'(SQL:select * from
myTab1
wheremyTab1
.my_tab3_id
in (1, 2))”
myTab3.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class myTab3 extends Model
{
//
protected $table = 'my_tab3s';
public $timestamps = true;
protected $fillable = [
'coolField',
'muhCurrentDate',
'rast',
'myTab1_id'
];
public function myTab1(){
return $this->hasOne('App\myTab1');
}
}
myTab1.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class myTab1 extends Model
{
//
public function scopeBigger($query){
return $query->where('id','>','1');
}
public function scopeHasLetterZ($query){
return $query->where('someField','like','%z%');
}
public function gimmeAll(){
return myTab1::All();
}
protected $table = 'myTab1';
public $timestamps = true;
protected $fillable = [
'someField'
];
public function myTab3(){
return $this->belongsTo('App\myTab3');
}
}
myTab3Controller.php 索引方法
public function index()
{
/*$dataSet = myTab3::All();*/
//$dataSet->myTab1()->get();
$dataSet = myTab3::with('myTab1')->get();
return view('myTab3.index',compact('dataSet'));
}
查看零件
@foreach($dataSet as $data)
<tr>
<td>{{$data->id}}</td>
<td>{{$data->coolField}}</td>
<td>{{$data->muhCurrentDate}}</td>
<td>{{$data->created_at}}</td>
<td>{{$data->updated_at}}</td>
<td>{{$data->rast}}</td>
<td>{{$data->myTab1->someField}}</td>
</tr>
@endforeach
