在整数上调用成员函数 toArray()

Question

User.php

public function role()
{

    return $this->belongsToMany('App\Models\Role','user_role','user_id','role_id');

}

//проверка принадлежит ли пользователь к какой либо роли
public function  isEmloyee(){
    $role=$this->role->toArray();
    return !empty($role);
}
//проверка имеетли пользователь определению роли
public function hasRole($check){

    return in_array($check,array_pluck($this->role->toArray(),'name'));
}
//получение идентификатора роли
private function getIdinArray($array,$term){
    foreach ($array as $key => $value){
        if ($value == $term){
            return $key +1;
        }
        return false;
    }
}
//добавление роли пользователя
public function makeEmployee($title){
    $assiqned_role = array();
    $role = array_pluck(Role::all()->toArray(),'name');
    switch ($title){
        case 'admin':
            $assiqned_role[] = $this->getIdinArray($role,'admin');
        case 'client':
            $assiqned_role[] = $this->getIdinArray($role,'client');
            break;
        default:
            $assiqned_roles[] = false;
    }
    $this->role()->attach($assiqned_role);
}

Role.php

class Role extends Model
{

   public function users()
   {

       return $this->belongsToMany('App\Models\User','user_role','role_id');
   }

}

OwnerMiddleware.php

<?php

namespace App\Http\Middleware;

use Closure;


class OwnerMiddleware
{
    public function handle($request, Closure $next,$role)
    {

        if(!$request->user()->hasRole($role)) {
            return redirect('/');
        }

        return $next($request);
    }
}

Answer 1

您在数据库中有role 列。它保留对您的role 关系集合的访问。您应该删除它或将role() 关系重命名为roles()。此外，belongsToMany 意味着用户可以拥有多个角色。

另外，我要注意的是集合有自己的方法in_array => contains，array_pluck => pluck。你可以这样优化你的代码：

public function roles()
{
    return $this->belongsToMany(Role::class, 'user_role');
}

public function isEmloyee(){
    return $this->roles->isNotEmpty();
}

public function hasRole($name){
    return $this->roles->pluck('name')->contains($name);
}

public function makeEmployee($name){
    $role = Role::where('name', $name)->first();
    if($role){
        $this->role()->attach($role->id);
    }
}
