Nova 2.0 Laravel 5.8
我有一个新星资源Document
(包含文件url,相关外键和标题),为此我定义了policy
,其中create
和update
为false以及所有其他设置为true时,PDF是从其他资源生成的,因此我不需要允许创建或编辑它,现在一切正常,但是我尝试下载此文档资源上的另一个action
这些文件,给我错误“ Sorry you are not authorized to take this action
”,因此如何在action
上使用此Policy
。
DocumentPolicy类
<?php
namespace App\Policies;
use App\User;
use App\Models\Document;
use Illuminate\Auth\Access\HandlesAuthorization;
class DocumentPolicy
{
use HandlesAuthorization;
/**
* Determine whether the user can view any documents.
*
* @param \App\User $user
* @return mixed
*/
public function viewAny(User $user)
{
return true;
}
/**
* Determine whether the user can view the document.
*
* @param \App\User $user
* @param \App\Document $document
* @return mixed
*/
public function view(User $user, Document $document)
{
return true;
}
/**
* Determine whether the user can create documents.
*
* @param \App\User $user
* @return mixed
*/
public function create(User $user)
{
return false;
}
/**
* Determine whether the user can update the document.
*
* @param \App\User $user
* @param \App\Document $document
* @return mixed
*/
public function update(User $user, Document $document)
{
return false;
}
/**
* Determine whether the user can delete the document.
*
* @param \App\User $user
* @param \App\Document $document
* @return mixed
*/
public function delete(User $user, Document $document)
{
return true;
}
/**
* Determine whether the user can restore the document.
*
* @param \App\User $user
* @param \App\Document $document
* @return mixed
*/
public function restore(User $user, Document $document)
{
return true;
}
/**
* Determine whether the user can permanently delete the document.
*
* @param \App\User $user
* @param \App\Document $document
* @return mixed
*/
public function forceDelete(User $user, Document $document)
{
return true;
}
public function download(User $user, Document $document)
{
return true;
}
}
答案 0 :(得分:1)
出现错误的原因是因为您的update
方法在策略中返回false。
默认情况下,如果更新为false,Nova将不允许该操作。要对此进行测试,您可以尝试将其设置为true
,然后再次进行测试。
要解决此问题,您必须更改注册操作的方式,以添加自定义回调以处理用户是否可以运行该操作的情况:
public function actions(Request $request)
{
return [
(new DownloadDocument)->canRun(function ($request, $document) {
return $request->user()->can('download', $document);
}),
];
}
这样,它将检查文档策略中的download
方法,而不是操作的update
方法。
