Laravel 08 文章列表页实现

• 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)
                

                    
{{$post->title}}
                    
{{$post->created_at->toFormattedDateString()}} by Kassandra Ankunding2

                    
{{$post['content']}}

• 时间格式

• 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
    ];
});

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)
   

                    
{{str_limit($post->title,30,'...')}}
                    
{{$post->created_at->toFormattedDateString()}} by Kassandra Ankunding2

      
{{str_limit($post['content'],100,'..more..')}}

 @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()}}
