Question

我创建了我的第一个Laravel政策。我有一个基本上新鲜的laravel 5.4项目，它有一个Project模型。我创建了一个名为ProjectPolicy的策略，但是我无法使所有方法都能正常工作。

如果我致电$user->can('create', Project::class)，我会在这里打电话给＆＃39; dump并返回true。但是，视图，创建和删除操作永远不会到达ProjectPolicy。＆＃34;此处＆＃34;永远不会被转储，总是返回false。我无法想到或找到任何理由，为什么一种政策方法可行，而其他政策方法则不然。我错过了什么？

应用\策略\ ProjectPolicy.php

namespace App\Policies;

use App\User;
use App\Project;
use Illuminate\Auth\Access\HandlesAuthorization;

class ProjectPolicy
{
    use HandlesAuthorization;


    /**
     * Determine whether the user has a specific ability for projects.
     *
     * @param  \App\User  $user
     * @param  \App\Project  $project
     * @return mixed
     */
    public function before($user, $ability)
    {
        var_dump('here');
    }

    /**
     * Determine whether the user can view the project.
     *
     * @param  \App\User  $user
     * @param  \App\Project  $project
     * @return mixed
     */
    public function view(User $user, Project $project)
    {
        return true;
    }

    /**
     * Determine whether the user can create projects.
     *
     * @param  \App\User  $user
     * @return mixed
     */
    public function create(User $user)
    {
        return true;
    }

    /**
     * Determine whether the user can update the project.
     *
     * @param  \App\User  $user
     * @param  \App\Project  $project
     * @return mixed
     */
    public function update(User $user, Project $project)
    {
        return true;
    }

    /**
     * Determine whether the user can delete the project.
     *
     * @param  \App\User  $user
     * @param  \App\Project  $project
     * @return mixed
     */
    public function delete(User $user, Project $project)
    {
        return true;
    }
}

AuthServiceProvider.php

namespace App\Providers;

use App\Project;
use App\Policies\ProjectPolicy;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        Project::class => ProjectPolicy::class,
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //
    }
}

问题可能是您在没有传递项目实例的情况下调用$user->can('view', Project::class)。尝试调用$user->can('view', $project)，其中$ project是项目类的一个实例，用于在函数定义中需要项目的所有方法。

Laravel策略忽略查看，更新和删除但创建工作正常
