本篇是接着 laravel中使用WangEditor及多图上传(下篇)
因此咱们这里不演示怎么新建项目了。
下载以前的项目,完成安装。
php
为了不后面踩到vue版本的坑,请务必阅读此部分
package.json
{ "private": true, "scripts": { "prod": "gulp --production", "dev": "gulp watch" }, "devDependencies": { "bootstrap-sass": "^3.3.7", "gulp": "^3.9.1", "jquery": "^3.1.0", "laravel-elixir": "^6.0.0-14", "laravel-elixir-vue-2": "^0.2.0", "laravel-elixir-webpack-official": "^1.0.2", "lodash": "^4.16.2", "vue": "^2.0.1", "vue-resource": "^1.0.3" } }
gulpfile.js
将原来的require('laravel-elixir-vue');
修改成require('laravel-elixir-vue-2');
css
const elixir = require('laravel-elixir'); require('laravel-elixir-vue-2'); /* |-------------------------------------------------------------------------- | Elixir Asset Management |-------------------------------------------------------------------------- | | Elixir provides a clean, fluent API for defining some basic Gulp tasks | for your Laravel application. By default, we are compiling the Sass | file for our application, as well as publishing vendor resources. | */ elixir(mix => { mix.sass('app.scss') .webpack('app.js'); });
resource/assets/js/app.js
将原来的el: 'body'
改成el: '#app'
vue
const app = new Vue({ el: '#app' });
(若是以前没有执行此操做)
jquery
npm install
咱们须要一个User模型(laravel附带),一个Post模型和一个Favorite模型以及它们各自的迁移文件。
由于咱们以前建立过了Post
的模型,因此咱们只须要建立一个Favorite
模型便可。
webpack
php artisan make:model App\Models\Favorite -m
这会建立一个Favorite
模型以及迁移文件。
ios
posts
迁移表及favorites
的up
方法给posts
表在id
字段后面新增一个user_id
字段
laravel
php artisan make:migration add_userId_to_posts_table --table=posts
修改database/migrations/2018_01_18_145843_add_userId_to_posts_table.php
git
public function up() { Schema::table('posts', function (Blueprint $table) { $table->integer('user_id')->unsigned()->after('id'); }); }
database/migrations/2018_01_18_142146_create_favorites_table.php
github
public function up() { Schema::create('favorites', function (Blueprint $table) { $table->increments('id'); $table->integer('user_id')->unsigned(); $table->integer('post_id')->unsigned(); $table->timestamps(); }); }
该favorites
表包含两列:
web
user_id 被收藏文章的用户ID。 post_id 被收藏的帖子的ID。
而后进行表迁移
php artisan migrate
由于咱们以前就已经建立过了,因此这里就不须要重复建立了。
若是你没有建立过用户认证模块,则须要执行php artisan make:auth
修改routes/web.php
Auth::routes(); Route::post('favorite/{post}', 'ArticleController@favoritePost'); Route::post('unfavorite/{post}', 'ArticleController@unFavoritePost'); Route::get('my_favorites', 'UsersController@myFavorites')->middleware('auth');
因为用户能够将许多文章标记为收藏夹,而且一片文章能够被许多用户标记为收藏夹,因此用户与最收藏的文章之间的关系将是多对多的关系。要定义这种关系,请打开User
模型并添加一个favorites()
app/User.php
注意post
模型的命名空间是App\Models\Post
因此注意要头部引入use App\Models\Post;
public function favorites() { return $this->belongsToMany(Post::class, 'favorites', 'user_id', 'post_id')->withTimeStamps(); }
第二个参数是数据透视表(收藏夹)的名称。第三个参数是要定义关系(User)的模型的外键名称(user_id),而第四个参数是要加入的模型(Post)的外键名称(post_id)。
注意到咱们连接withTimeStamps()到belongsToMany()。这将容许插入或更新行时,数据透视表上的时间戳(create_at和updated_at)列将受到影响。
由于咱们以前建立过了,这里也不须要建立了。
若是你没有建立过,请执行php artisan make:controller ArticleController
favoritePost
和unFavoritePost
两个方法注意要头部要引入use Illuminate\Support\Facades\Auth;
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Models\Post; use Illuminate\Support\Facades\Auth; class ArticleController extends Controller { public function index() { $data = Post::paginate(5); return view('home.article.index', compact('data')); } public function show($id) { $data = Post::find($id); return view('home.article.list', compact('data')); } public function favoritePost(Post $post) { Auth::user()->favorites()->attach($post->id); return back(); } public function unFavoritePost(Post $post) { Auth::user()->favorites()->detach($post->id); return back(); } }
axios
模块
npm install axios --save
resource/assets/js/bootstrap.js
在最后加入
import axios from 'axios'; window.axios = axios;
// resources/assets/js/components/Favorite.vue <template> <span> <a href="#" v-if="isFavorited" @click.prevent="unFavorite(post)"> <i class="fa fa-heart"></i> </a> <a href="#" v-else @click.prevent="favorite(post)"> <i class="fa fa-heart-o"></i> </a> </span> </template> <script> export default { props: ['post', 'favorited'], data: function() { return { isFavorited: '', } }, mounted() { this.isFavorited = this.isFavorite ? true : false; }, computed: { isFavorite() { return this.favorited; }, }, methods: { favorite(post) { axios.post('/favorite/'+post) .then(response => this.isFavorited = true) .catch(response => console.log(response.data)); }, unFavorite(post) { axios.post('/unfavorite/'+post) .then(response => this.isFavorited = false) .catch(response => console.log(response.data)); } } } </script>
在视图组件使用以前,咱们先引入字体文件resource/views/layouts/app.blade.php
头部引入字体文件
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" />
并在app.blade.php
添加个人收藏夹
连接
// 加在logout-form以后 <form id="logout-form" action="{{ url('/logout') }}" method="POST" style="display: none;"> {{ csrf_field() }} </form> <a href="{{ url('my_favorites') }}">个人收藏夹</a>
使用组件
// resources/views/home/article/index.blade.php if (Auth::check()) <div class="panel-footer"> <favorite :post={{ $list->id }} :favorited={{ $list->favorited() ? 'true' : 'false' }} ></favorite> </div> endif
而后咱们要建立favorited()
打开app/Models/Post.php
增长favorited()
方法
注意要在头部引用命名空间
use App\Models\Favorite;
use Illuminate\Support\Facades\Auth;
public function favorited() { return (bool) Favorite::where('user_id', Auth::id()) ->where('post_id', $this->id) ->first(); }
引入Favorite.vue
组件resources/assets/js/app.js
Vue.component('favorite', require('./components/Favorite.vue'));
编译
npm run dev
效果图
![]()
个人收藏夹
php artisan make:controller UsersController
修改app/Http/Controllers/UsersController.php
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use Illuminate\Support\Facades\Auth; class UsersController extends Controller { public function myFavorites() { $myFavorites = Auth::user()->favorites; return view('users.my_favorites', compact('myFavorites')); } }
添加视图文件
// resources/views/users/my_favorites.blade.php extends('layouts.app') @section('content') <div class="container"> <div class="row"> <div class="col-md-8 col-md-offset-2"> <div class="page-header"> <h3>My Favorites</h3> </div> @forelse ($myFavorites as $myFavorite) <div class="panel panel-default"> <div class="panel-heading"> <a href="/article/{{ $myFavorite->id }}"> {{ $myFavorite->title }} </a> </div> <div class="panel-body" style="max-height:300px;overflow:hidden;"> <img src="/uploads/{!! ($myFavorite->cover)[0] !!}" style="max-width:100%;overflow:hidden;" alt=""> </div> @if (Auth::check()) <div class="panel-footer"> <favorite :post={{ $myFavorite->id }} :favorited={{ $myFavorite->favorited() ? 'true' : 'false' }} ></favorite> </div> @endif </div> @empty <p>You have no favorite posts.</p> @endforelse </div> </div> </div> @endsection
而后从新向一下根目录routes/web.php
添加一条路由
Route::get('/', 'ArticleController@index');
最后效果图
