计算 blade 视图中用户的帖子总数
Counting total posts by a user in the blade view
我已将我博客中所有帖子的 collection 发送到我的索引视图,然后使用以下代码计算每个用户发布的帖子总数。
<p class="joined-text">Posts: {{count(App\Posts::where('user_id', $post->user->id)->get())}}</p>
从 blade 视图中执行此操作是一种不好的做法吗?如果是,我将如何实现?
型号
class Posts extends Model
{
public function user()
{
return $this->belongsTo(User::class);
}
public function comments()
{
return $this->hasMany(Comments::class, 'post_id');
}
}
class User extends Authenticatable
{
public function posts()
{
return $this->hasMany('\App\Posts::class');
}
public function comments()
{
return $this->hasMany(Comments::class);
}
}
是的,这很糟糕。
如果 posts
中有 user_id
字段,您可以使用 relationships table
class User extends Model
{
public function posts()
{
return $this->hasMany('App\Post');
}
}
在控制器中
return view('sth')->with(['posts'=>$user->posts]);
然后在视图中
$posts->count();
或者,如果您不需要帖子,则只获取计数
$postCount = $user->posts()->count();
简单的解决方案:
<p class="joined-text">Posts: {{ App\Posts::where('user_id', $post->user_id)->count() }}</p>
已更新
完整且更好的解决方案:
Post.php
:
public function user(){
return $this->belongsTo(App\User::class);
}
User.php
:
public function posts(){
return $this->hasMany(App\Post::class);
}
public function getPostsCountAttribute(){
return $this->posts()->count();
}
blade:
<p class="joined-text">Posts: {{ $post->user->posts_count }}</p>
