Laravel Blade @foreach not working
提问by Omar Gonzalez
I'm learning Laravel 4, so far so good. But for some weird reason blade's @foreach doesn't seem to work for a simple query. My code is:
我正在学习 Laravel 4，到目前为止一切顺利。但是由于某些奇怪的原因，blade 的 @foreach 似乎不适用于简单的查询。我的代码是：
Route:
路线：
Route::get('/users', function(){
$users = User::all();
return View::make('users/index')->with('users',$users);
});
Now in index.blade.php my code is:
现在在 index.blade.php 我的代码是：
@foreach ($users as $user)
<p>User: {{ $user->username }}</p>
@endforeach
The weird thing is that when I dump the object in the view, it does work:
奇怪的是，当我在视图中转储对象时，它确实有效：
{{ dd($users->toArray())}}
The DB data is displayed raw as an array.
DB 数据以数组的形式原始显示。
I'm not really sure what am I doing wrong here, this is pretty much code from the beginners tutorial.
我不太确定我在这里做错了什么，这几乎是初学者教程中的代码。

You should use a template/layout(but you didn't use according to your view on Github) and child views should extend it, for example, your index.blade.phpview should be look something like this:
你应该使用一个template/layout（但你没有根据你在 Github上的观点使用）并且子视图应该扩展它，例如，你的index.blade.php视图应该是这样的：
// index.blade.php
@extends('layouts.master')
@section('content')
@foreach ($users as $user)
<p>User: {{ $user->username }}</p>
@endforeach
@stop
Now make sure that, in your app/views/layoutsfolder you have a master.blade.phplayout and it contains something like this:
现在确保在您的app/views/layouts文件夹中有一个master.blade.php布局，它包含如下内容：
// master.blade.php
<!doctype html>
<html class="no-js" lang="">
<head>
<style></style>
</head>
<body>
<div class='content'>
@yield('content') {{-- This will show the rendered view data --}}
</div>
</body>
</html>
Also dd($users->toArray())works because it dumps the $user->toArray()using var_dumpand exits the script using diefunction, the ddmeans dump and die.
也dd($users->toArray())有效，因为它转储$user->toArray()usingvar_dump并退出脚本 usingdie函数，dd即dump and die.
