php - Laravel Blade 模板@extends

Question

在我看来，我正在扩展一个默认 Blade 模板，它充当我的主模板。我有一个 ViewComposer 设置，它为该模板提供许多变量。

我遇到了一种情况，我需要访问 index.blade.php 中的这些变量之一，这是启动 @extends 函数的页面。

通过 ViewComposer 传递的变量是否达到初始 View 的范围？或者我需要创建另一个 ViewComposer 来传递相同的变量。

ViewComposer

<?php

namespace App\Http\ViewComposers;

use Illuminate\View\View;
use Illuminate\Http\Request;
use App\Repositories\UserRepository;
use Sentinel;
use App\ProjectUsers;

class MasterComposer
{
    /**
     * The user repository implementation.
     *
     * @var UserRepository
     */
    protected $users;
    private $request;

    /**
     * Create a new profile composer.
     *
     * @param  UserRepository  $users
     * @return void
     */
    public function __construct(Request $request)
    {

        $this->request = $request;
        // Dependencies automatically resolved by service container...
        $uid = Sentinel::getUser()->id;
        $this->users = ProjectUsers::where("user_id", '=', $uid)->get();
    }

    /**
     * Bind data to the view.
     *
     * @param  View  $view
     * @return void
     */
    public function compose(View $view)
    {
        $view->with('projects', $this->users);
        $view->with('activeProject', $this->request->session()->get("activeProject"));
    }
}

ComposerServiceProvider

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ComposerServiceProvider extends ServiceProvider {
    /**
     * Register bindings in the container.
     *
     * @return void
     */
    public function boot() {
        // Using class based composers...
        view ()->composer ( 'admin/layouts/default', 'App\Http\ViewComposers\MasterComposer' );
    }

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register() {
        //
    }
}

index.blade.php

@extends('admin/layouts/default')
{{ $activeProject }}

这最终给了我一个 undefined variable 错误。

Undefined variable: activeProject (View: /home/laravel/public_html/base/resources/views/admin/index.blade.php)

是的，主布局中可用的所有变量都将传递给其任何子布局。
