Laravel 4: Using flexible layouts within routes
提问by quantme
I have an application without controllers and read about controller layoutsin laravel 4 documentationand this other article too, but I don't know where to start for implement it within routes (version 4), how can I do that?
我有一个没有控制器的应用程序，并在laravel 4 文档和另一篇文章中阅读了有关控制器布局的信息，但我不知道从哪里开始在路由（版本 4）中实现它，我该怎么做？
Error received: InvalidArgumentException, View [master] not found.
收到错误：InvalidArgumentException，未找到视图 [master]。

应用程序/routes.php
<?php
View::name('layouts.master', 'layout');
$layout = View::of('layout');
Route::get('users/create', array('as' => 'users.create', function() use($layout) {
//@TODO: load view using 'layouts.master',
// desirable: append 'users.create' and 'users.menu' views to sidebar and content sections.
//return View::make('users.create');
return $layout->nest('content', 'master');
}));
?>

<html>
<body>
@section('sidebar')
This is the master sidebar.
@show

{{ Form::open() }}
{{ Form::text('name') }}
{{ Form::submit('submit') }}
{{ Form::close() }}
app/views/users/menu.blade.php
应用程序/视图/用户/menu.blade.php
<!-- This is appended to the master sidebar -->
<p><a href="users/create">Create user</a></p>
Update: I modified example code to clarify what I want to do. Check app/routes.phpand its comments
更新：我修改了示例代码以阐明我想要做什么。检查app/routes.php及其评论

The code in your routes file is trying to nest the master layout within itself, which isn't really what you want. You're getting the error because 'master'would look for app/views/master.blade.php. That's easily fixed by changing it to 'layouts.master', but I wouldn't like to think what might happen...
路由文件中的代码试图将主布局嵌套在其自身中，这并不是您真正想要的。您收到错误是因为'master'会查找app/views/master.blade.php. 这很容易通过将其更改为 来解决'layouts.master'，但我不想考虑可能会发生什么......
The root cause of the issue you're having is the difference between "yielding" views from a Blade template, and nesting them from a route. When you nest a route, you need to echoit rather than using the @yieldtag.
您遇到的问题的根本原因是从 Blade 模板“生成”视图与从路由嵌套它们之间的差异。当你嵌套一个路由时，你需要echo它而不是使用@yield标签。
// File: app/routes.php
View::name('layouts.master', 'layout');
$layout = View::of('layout');
Route::get('users/create', array('as' => 'users.create', function() use ($layout)
{
return $layout
->nest('content', 'users.create')
->nest('sidebar', 'users.menu');
}));
/*

| View Composer
|--------------------------------------------------------------------------

| Code in this method will be applied to all views that use the master
| layout. We use that to our advantage by injecting an "empty" sidebar
| when none is set when returning the view. It will error otherwise.
|
*/
View::composer('layouts.master', function($view)
{
if (!array_key_exists('sidebar', $view->getData()))
{
$view->with('sidebar', '');
}
});
// File: app/views/layouts/master.blade.php
<html>
<body>
@section('sidebar')
This is the master sidebar
{{ $sidebar }}
@show
<div class="container">
{{ $content }}
</div>
</body>
</html>
Laravel's View composersare a powerful tool. If you have any data (eg logged-in user info) used by all views that share the same template(s), you can use the composers to save injecting the data every time you load the view.
Laravel 的View composers是一个强大的工具。如果您有共享相同模板的所有视图使用的任何数据（例如登录用户信息），您可以使用作曲家来保存每次加载视图时注入数据。

You could also use the @parent tag to append content, assuming you;re using blade for templating. E.g. (in the view)
您还可以使用 @parent 标签来附加内容，假设您正在使用刀片进行模板化。例如（在视图中）
@section('sidebar')
@parent
<p>This is appended to the master sidebar.</p>
@stop
回答by Can Geli?
You don't need to use nesting views if you're using blade.
如果您使用刀片，则不需要使用嵌套视图。
app/views/users/create.blade.php
应用程序/视图/用户/create.blade.php
You need to extend the master.blade
你需要扩展 master.blade
@extends('layouts.master')
@section('content')
// form stuff here
@stop
Now, all you need to do is call create.blade
现在，您需要做的就是致电 create.blade
return View::make('users.create')
return View::make('users.create')

Just throwing this out there as a possible solution using controller routing (whereas you can set the template from within the controller).
只需将其作为使用控制器路由的可能解决方案（而您可以从控制器内设置模板）就可以了。
app/routes.php
应用程序/routes.php
Route::controller('something', 'SomethingController');
app/controllers/SomethingController.php
应用程序/控制器/SomethingController.php
class SomethingController extends BaseController {
protected $layout = "templates.main"; // denotes views/templates/main.blade.php
public function getIndex() { // the "landing" page for "/something" or "/something/index"
$this->layout->content = View::make('something.index')->with("myVar", "Hello, world!"); // load in views/something/index.blade.php INTO main.blade.php
}
public function getTest() { // for "/something/test"
$this->layout->content = View::make('something.index')->nest("widget", "something.widget", array("myVar" => "Hello, World!"));
}
}
app/views/templates/main.blade.php
应用程序/视图/模板/main.blade.php
@include('templates.partials.header')
@yield('something')
@yield('content')
@include('templates.partials.footer')
app/views/something/widget.blade.php
应用程序/视图/东西/widget.blade.php
I'm a widget. {{ $myVar }}
app/views/something/index.blade.php
应用程序/视图/东西/index.blade.php
@section('something')
I will go in the 'something' yield in main.blade.php
@stop
@section('content')
I will go in the 'content' yield in main.blade.php.
{{ $myVar }}
{{ $widget }}
@stop
?>
Now you can test http://myserver/somethingand http://myserver/something/testto see the differences. Note: not tested but as a rough example.
现在您可以测试http://myserver/something并http://myserver/something/test查看差异。注意：未经测试，只是一个粗略的例子。
