[英]PHP Fatal error: Call to undefined function Laravel tinker
I'm trying to establish a relation between two tables (Roles and Abilities) but when I run the function allowTo()
it says is undefined .我正在尝试在两个表(角色和能力)之间建立关系,但是当我运行 function allowTo()
时,它说是undefined 。 I tried to clear the cache and config but didn't do anything.我试图清除缓存和配置,但没有做任何事情。 If anyone could help that'd be great, thanks!如果有人能帮忙就太好了,谢谢!
Model : Model :
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Role extends Model
{
protected $guarded = [];
public function abilities(){
return $this->belongsToMany(Ability::class)->withTimestamps();
}
public function allowTo($ability){
$this->abilities()->save($ability);
}
