8. 小例子，实现一个简单的blog之select

1. 注册路由

Route::get('articles', 'ArticlesController@index');
Route::get('articles/{id}', 'ArticlesController@show');

2. 创建ArticlesController类

  php artisan make:controller ArticlesController

App\Http\Controllers\ArticlesController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Article;

class ArticlesController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $articles = Article::all();
        return view('articles.index', compact('articles'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $article = Article::findOrFail($id);
        return view('articles.show', compact('article'));
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

3. 视图层view

resources/views

resources/views/articles/index.blade.php

@extends('app')

@section('content')
    <h1>Articles</h1>
    <hr>
    @foreach($articles as $article)
        <h3><a href="{{ url('articles', $article->id) }}">{{ $article->title }}</a></h3>
        <div class="body">
            {{ $article->body }}
        </div>
    @endforeach
@stop

resources/views/articles/show.blade.php

@extends('app')

@section('content')
    <h1>{{ $article->title }}</h1>
    <hr>
    <div class="body">
        {{ $article->body }}
    </div>
@stop
