Question

我想在laravel 5.2 app中实现基于用户的侧边栏，其中包含大多数帖子和评论，我想向前5位用户展示最多帖子和评论。例如：用户名：“Mohcin”，帖子：30，回答：20 提前致谢

Answer 1

步骤：

打开app/Providers/AppServiceProvider.php
在此文件中，您有一个空的（可能）boot方法。
在此方法中，您可以创建视图编辑器以传递特定视图的数据。

像这样：

//Assuming you want to pass the var to the view: sidebar.blade.php inside resources/views/layout
view()->composer('layout.sidebar', function($view){
    $topUsers = User::topUsers(); //Create a query or scope to do this...
    //After populate topUsers, you have to pass it to the view using:
    $view->with('topUsers', $topUsers);
});

在您的视图中：`resources / views / layout / sidebar.blade.php，您可以使用这样的简单$ topUsers访问用户：

foreach($topUsers as $user) {
    var_dump($user);
}

用户模型：

use Authenticatable, CanResetPassword;

/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'users';

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = ['name', 'email', 'password'];

/**
 * The attributes excluded from the model's JSON form.
 *
 * @var array
 */
protected $hidden = ['password', 'remember_token'];


    public function questions(){

        return $this->hasMany('\App\Question');
    }


    public function answers(){

        return $this->hasMany('\App\Answer');
    }

问题模型:(发布模型）

 public function User(){

  return $this->belongsTo('\App\User');

}


public function answers(){

        return $this->hasMany('\App\Answer');

}

public static function your_questions(){


    return static::where ('user_id','=',Auth::user()->id)->paginate(50);
}
public static function unsolved(){


    return static::where ('solved','=',0)->orderby('id','DESC')->latest()->paginate(50);
}
public static function unsolvedbar(){


    return static::where ('solved','=',0)->orderby('id','DESC')->latest()->take(3)->get();;
}


public function category()
{
    return $this->belongsTo('App\Category');
}

public function tags()
{
    return $this->belongsToMany('App\Tag');
}

实现了基于用户的侧边栏，其中包含大多数帖子和评论
