【问题描述】:
我目前在与 Laravel 4 的 n:n 关系方面遇到问题,我遇到了一个数据透视表错误,该数据透视表正在查询一个表,其中两个组件都是单数名称。我创建了一个数据透视表lands_objs 并填充它:
型号为:
<?php
class Obj extends Eloquent
{
protected $guarded = array();
public static $rules = array();
public $timestamps = false;
public function land()
{
return $this->belongsToMany('Land');
}
<?php
class Land extends Eloquent
{
protected $guarded = array();
public static $rules = array();
public $timestamps = false;
public function objs()
{
return $this->belongsToMany('Obj');
}
}
这是我按照标准填充数据透视表的方式。 lands、objs 和 lands_objs 表当然存在:
<?php
use Illuminate\Database\Migrations\Migration;
class CreateLandsObjsTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('lands_objs', function($table) {
$table->integer('land_id');
$table->integer('obj_id');
});
}
}
感谢 Eloquent,有了这个结构,我应该可以做到:
$land = Land::find(1); //checked loads land fine
$objs = $land->objs; //--> HERE I TAKE THE ERROR
但我认为错误:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'taylor.land_obj' doesn't exist
(SQL: select `objs`.*, `land_obj`.`land_id` as `pivot_land_id`, `land_obj`.`obj_id`
as `pivot_obj_id` from `objs` inner join `land_obj` on `objs`.`id` = `land_obj`.`obj_id`
where `land_obj`.`land_id` = ?) (Bindings: array ( 0 => 1, ))
Laravel 不应该创建表lands_objs 尽管查询land_obj 吗?我错过了什么吗?
非常感谢。
