关于Route::resource
app/Http/routes.phpRoute::group(['middleware' => ['web']], function () { Route::get('/articles','ArticlesController@index'); Route::get('/articles/create','ArticlesController@create'); Route::get('/articles/{id}','ArticlesController@show'); Route::post('/articles','ArticlesController@store'); Route::get('/articles/{id}/edit','ArticlesController@edit');}); 一般我们的一个普通网站的文章有这些url，这些url分别是文章编辑，创建，查看列表，查看文章内容等，laravel框架对于这些有规律的url做了一个叫RESTful Resource Controllers的可重用的资源控制器
php artisan route:list //用这个命令可以查看当前laravel项目的路由情况+--------+----------+--------------------+------+------------------------------------------------+------------+| Domain | Method | URI | Name | Action | Middleware |+--------+----------+--------------------+------+------------------------------------------------+------------+| | POST | articles | | App\Http\Controllers\ArticlesController@store | web || | GET|HEAD | articles | | App\Http\Controllers\ArticlesController@index | web || | GET|HEAD | articles/create | | App\Http\Controllers\ArticlesController@create | web || | GET|HEAD | articles/{id} | | App\Http\Controllers\ArticlesController@show | web || | GET|HEAD | articles/{id}/edit | | App\Http\Controllers\ArticlesController@edit | web |+--------+----------+--------------------+------+------------------------------------------------+------------+ 改为使用resource
app/Http/routes.phpRoute::group(['middleware' => ['web']], function () { Route::resource('/articles','ArticlesController'); //将之前的一批路由改为这个。}); php artisan route:list+--------+-----------+--------------------------+------------------+-------------------------------------------------+------------+| Domain | Method | URI | Name | Action | Middleware |+--------+-----------+--------------------------+------------------+-------------------------------------------------+------------+| | GET|HEAD | articles | articles.index | App\Http\Controllers\ArticlesController@index | web || | POST | articles | articles.store | App\Http\Controllers\ArticlesController@store | web || | GET|HEAD | articles/create | articles.create | App\Http\Controllers\ArticlesController@create | web || | DELETE | articles/{articles} | articles.destroy | App\Http\Controllers\ArticlesController@destroy | web || | PUT|PATCH | articles/{articles} | articles.update | App\Http\Controllers\ArticlesController@update | web || | GET|HEAD | articles/{articles} | articles.show | App\Http\Controllers\ArticlesController@show | web || | GET|HEAD | articles/{articles}/edit | articles.edit | App\Http\Controllers\ArticlesController@edit | web |+--------+-----------+--------------------------+------------------+-------------------------------------------------+------------+//再次查看路由，依旧会生成这些有规律的常用的路由list，不过需要注意一些路由，有些是用了PATCH方法，这个是因为浏览器本身只支持get和post，对于其他的方法是无法处理的，所以laravel会在表单的里面提供支持这些其他的方法的语法，当然，在这里我们只需要知道有这些路由，这些路由有这些方法 详情参考：https://laravel测试数据/docs/5.2/controllers#restful-resource-controllers
在controller里面编写edit方法，
app/Http/Controllers/ArticlesController.php public function edit($id){ $article = Articles::findOrFail($id); //findOrFail方法是laravel的model的提供的可以处理model数据的方法，而model是直接关联数据库的，所以可以理解为直接操作数据库的方法 //这里是查找主键为$id的项，然后返回一个model return view('articles.edit',compact('article')); }
以下是findOrFail的介绍
Model|Collection findOrFail(mixed $id, array $columns = array('*'))Find a model by its primary key or throw an exception.Parametersmixed $id array $columns Return ValueModel|Collection 创建edit的blade模板
resources/views/articles/edit.blade.php@extends('layout.app')@section('content') {{$article->title}}
//用这里来验证是否能够查找到$article的title信息 @if($errors->any()) @foreach($errors->all() as $error) {{$error}} @endforeach @endif@stop 查看数据库
id title content publish_at created_at updated_at5 我是一篇新文章 你好 2016-05-21 0 2016-05-21 07:32:48 2016-05-21 07:32:48
在浏览器访问http://localhost:8000/articles/5/edit出来的是正确的title
编辑PATCH method
确认edit模板和edit方法是正常之后，再次修改edit模板
resources/views/articles/edit.blade.php@extends('layout.app')@section('content') {{$article->title}}
{!! Form::open(['method'=>'PATCH','url'=>'/articles'.$article->id]) !!} //因为之前的提到的用resource路由，其中有一个路由是用PATCH方法的，所以在这里写 {!! Form::label('title', 'Title:') !!} {!! Form::text('title', null, ['class' => 'form-control']) !!}
