Question

这是我的问题：

$batchDetails=BatchModel::join('class', 'batch.Class', '=', 'class.AutoID')
    ->get()
    ->toArray();

BatchModel：

<?php
class BatchModel extends Eloquent
{
    protected $primaryKey = 'AutoID';
    protected $table = 'batch';  
    protected $fillable = array('Class','batch','Statedate','Enddate');

    public $timestamps = false;

    public function batch(){
        return $this->hasMany('BatchModel', 'Class');
    }

    public static $rules = array(     
        'Class' => 'required',         
        'batch' => 'required', 
        'Statedate' => 'required', 
        'Enddate' => 'required', 
        );

}

ClassModel：

<?php
class ClassModel extends Eloquent
{

    protected $primaryKey = 'AutoID';
    protected $created_at = 'CreatedAt';
    protected $updated_at = 'UpdatedAt';
    protected $table = 'class';
    protected $guarded = array('ClassName');
    protected $fillable = array('ClassName', 'ClassSection', 'ClassCode');

     public function classModel(){ 
        return $this->belongsTo('ClassModel', 'Class');
    }

    public $timestamps = true;


    public static $rules = array(
        'ClassName' =>  array('required', 'unique:class','regex:/^./'),
        'ClassSection' => 'required',
        'ClassCode' => array('required', 'unique:class')
                             );


}

我不想使用像“class and batch”这样的表名。我只想使用模型名称而不是表和表属性。

所以我的问题是如何才能使用模型名称进行上述连接查询？

您可以使用Eloquent relations。

class BatchModel extends Eloquent {
    public function classModel(){ // normally I'd use only "class" but that's a reserved word so..
        return $this->belongsTo('ClassModel', 'Class');
    }
}


class ClassModel extends Eloquent {
    protected $primaryKey = 'AutoID';
    public function batch(){
        return $this->hasMany('BatchModel', 'Class');
    }
}

不确定我是否把一切都搞定了，但它应该是这样的。现在您可以像这样查询：

$batchDetails = BatchModel::with('classModel')->get();

使用Eloquent ORM laravel加入多个表模型
