如何在Laravel 4中实现用户权限? [英] How to implement user permissions in Laravel 4?

问题描述

我基本上想要的是用户权限.

What I basically want is user permissions.

我的数据库中有一个名为"accounts"的表.有一个名为"group_id"的列. 我想在'group_id'= 3时设置它，那么用户是admin.然后，他可以查看特殊站点，按钮以及类似内容.我试图实现类似的东西:

I've got an table called 'accounts' in my database. There is a column called 'group_id'. I want to set it when the 'group_id' = 3, then the user is admin. Then he can view special sites, buttons, and things like that. I've tried to implement something like that:

public function ($roleName) {
    $role = $this->roles;

    if ($role->name == $roleName) {
        return true;
    }

    return false;
}

此外，我不知道该模型需要什么以及如何使用，我是否需要一个新模型以及类似的东西.

Also, I don't know what and how the model is needed, do I need an new one and things like that.

向您的用户模型添加一个方法，如果用户是管理员，则该方法返回true.在我们这里的例子中，只是我们的group_id等于3吗?"

Add a method to your User model that returns true if the user is an admin. In our case here, it's simply "is our group_id equal to 3?"

// models/User.php
class User extends Eloquent 
{
    ... 
    public function isAdmin()
    {
        return $this->group_id == 3;
    }

}

接下来添加一个可用于保护路线的过滤器

Next add a filter that can be used to protect routes

// filters.php
Route::filter('admin', function($route, $request)
{
    if ( ! Auth::user()->isAdmin())
    {
        return App::abort(401, 'You are not authorized.');
    }
});

最后使用过滤器保护一组路由.在这种简化的情况下，只有管理员用户可以访问/admin

Finally use the filter to protect a group of routes. I this simplified case, only an admin user could access /admin

// routes.php
Route::group(array('before' => array('auth|admin')), function()
{
    Route::get('/admin', function()
    {
        return Response::make("You're an admin!");
    }
});
