- 模型查找
//引入模型
user \App\Post;
//查找所有的数据，按时间排序，返回是对象形式;
$posts = Post::orderBy('created_at','desc')->get();
- 页面渲染
phpstorm快速查找 文件
ctrl + shift + n
@foreach($posts as $post)
<div class="blog-post">
<h2 class="blog-post-title"><a href="/posts/{{$post->id}}">{{$post->title}}</a></h2>
<p class="blog-post-meta">{{$post->created_at->toFormattedDateString()}} by <a href="/user/5">Kassandra Ankunding2</a></p>
<p>{{$post['content']}}</p>
<p class="blog-post-meta">赞 0 | 评论 0</p>
</div>
@endforeach

https://carbon.nesbot.com/docs/ - 数据填充
工厂代码
//Post模型的数据填充函数
$factory->define(App\Post::class, function (Faker $faker) {
return [
'title' => $faker->sentence(6),//6个字母
'content' => $faker->paragraph(10),//10个句子
];
});
https://github.com/fzaninotto/Faker
php artisan tinker
// 创建预览
factory(App\Post::class,10)->make()
//插入数据库
factory(App\Post::class,10)->create()
- 字符截断
用
str_limit(字符串，长度，超出部分代替字符)函数
@foreach($posts as $post)
<div class="blog-post">
<h2 class="blog-post-title"><a href="/posts/{{$post->id}}">{{str_limit($post->title,30,'...')}}</a></h2>
<p class="blog-post-meta">{{$post->created_at->toFormattedDateString()}} by <a href="/user/5">Kassandra Ankunding2</a></p>
<p>{{str_limit($post['content'],100,'..more..')}}</p>
<p class="blog-post-meta">赞 0 | 评论 0</p>
</div>
@endforeach
- 分页
在
post控制器中的index方法，调用分页函数paginate(单页的显示条数)
$posts = Post::orderBy('created_at','desc')->paginate(6);
在模板中
{{ $posts -> links() }}
{{$posts->links()}}
