Laravel5 Eloquent: 如何从特殊条件下获取几篇文章？

Question

首先，对不起我糟糕的英语。
我想通过 5 篇文章获得最高浏览量。我试过了，但是 Eloquent 查询有问题。

laravel 来源

<?php
    $up = "SELECT id FROM articles WHERE id IN (SELECT id from (SELECT id FROM articles ORDER BY view_count DESC LIMIT 0,5) x)";
    $builder = new \App\Article;
    $query = $builder->selectRaw("articles.*, $up");
?>
    @forelse($query->latest() as $article)
        <img src="{{ $article->thumbnail }}" alt="{{ $article->title }}" title="{{ $article->title }}">
    @empty
        <p class="text-center text-danger">
        empty...
        </p>
    @endforelse

数据库查询结果

MariaDB [test]> SELECT id FROM articles WHERE id IN (SELECT id from (SELECT id FROM articles ORDER BY view_count DESC LIMIT 0,5) x);
+------+
| id   |
+------+
| 4018 |
| 4045 |
| 3800 |
| 4011 |
| 4005 |
+------+
5 rows in set (0.00 sec)

我看过关于这个主题的其他帖子，但我没有得到解决方案。
感谢您的帮助。

Answer 1

5 篇按视图排序的文章，您只需在控制器中编写即可：

$articles = Article::orderBy('views', DESC)->take(5)->get();
return view('article', ['articles' => $articles
]);

在你的 article.blade.php 中：

@forelse($articles() as $article)
    <img src="{{ $article->thumbnail }}" alt="{{ $article->title }}" title="{{ $article->title }}">
@forelse
    <p class="text-center text-danger">
    empty...
    </p>
@endforelese

Answer 2

首先，您必须在控制器中使用您的服务 sttuf 来清理视图并遵守 MVC 模式。

所以在控制器中你可以使用 Eloquent 来做到这一点 :

$articles = App\Article::orderBy('view_count', 'desc')
               ->take(5)
               ->get();

return view('SomeView')->withArticles($articles);

并且在 SomeView.blade.php 中：

@forelse($articles as $article)
    <img src="{{ $article->thumbnail }}" alt="{{ $article->title }}" title="{{ $article->title }}">
@empty
    <p class="text-center text-danger">
    empty...
    </p>
@endforelse
