Laravel Nova indexQuery 范围重用

Question

我的应用程序确实有基于策略的权限管理，我正在使用 Nova 作为应用程序的后端。

现在 nova 内一切正常，我想为我的外部应用程序设置一个额外的 API。

我确实必须为我的大部分资源覆盖 indexQuery，因为用户只能访问有限的范围，例如对于 Customer 资源：

public static function indexQuery(NovaRequest $request, $query)
{
    $user = Auth::user();

    // Admins and office users can see all customers
    if($user->authorizeRoles(['admin', 'office'])) {
        return $query;
    }

    // A user can only see customers associated with a job they work on
    $query
        ->select('customers.*')
        ->join('jobs', 'jobs.customer_id', '=', 'customers.id')
        ->join('teams', 'jobs.team_id', '=','teams.id')
        ->join('team_user', 'teams.id', '=', 'team_user.team_id')
        ->where('team_user.user_id', '=', $user->id);

    return $query;
}

现在，对于 API，我基本上需要相同的范围，我想知道将这段代码放在哪里。我的第一个想法是向 Customer 模型添加一个范围，因此我将添加一个带有参数的范围：

/**
 * Limit the results to the customers the user is able to see
 * @param  \Illuminate\Database\Eloquent\Builder  $query
 * @param \App\User $user
 * @return \Illuminate\Database\Eloquent\Builder
 */
public function scopeVisibleToUser($query, $user) {
    if($user->authorizeRoles(['admin', 'office'])) {
        return $query;
    }

    // A user can only see customers associated with a job they work on
    $query
        ->select('customers.*')
        ->join('jobs', 'jobs.customer_id', '=', 'customers.id')
        ->join('teams', 'jobs.team_id', '=','teams.id')
        ->join('team_user', 'teams.id', '=', 'team_user.team_id')
        ->where('team_user.user_id', '=', $user->id);

    return $query;
}

有没有什么方法可以在 indexQuery 方法中应用范围而不创建虚拟客户对象？

use App\Customer as AppCustomer;

/**
 * Build an "index" query for the given resource.
 *
 * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
 * @param  \Illuminate\Database\Eloquent\Builder  $query
 * @return \Illuminate\Database\Eloquent\Builder
 */
public static function indexQuery(NovaRequest $request, $query)
{
    $user = Auth::user();
    return (new AppCustomer())->scopeVisibleToUser($query, $user);
}

Using real-time facades, you may treat any class in your application as if it were a facade.

use Facades\App\Customer as AppCustomer;

/**
 * Build an "index" query for the given resource.
 *
 * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
 * @param  \Illuminate\Database\Eloquent\Builder  $query
 * @return \Illuminate\Database\Eloquent\Builder
 */
public static function indexQuery(NovaRequest $request, $query)
{
    $user = Auth::user();
    return AppCustomer::visibleToUser($query, $user);
}
