在laravel 5.3中需要帮助以从多个数据库表中获取单个视图中的表中的数据

Question

As I am developing a project in larawel 5.3. and I am using two tables in database first users ans second points you can see my points table structure in this link. I want to get user id in laravel 5.3 controller with Auth::user()->id but it creates error their So when a transection occurs. it is saved in points table getting assousiated with user_id so net points of a user can can be taken as using folloing query

$points = Points::select(DB::raw("sum(p_add)-sum(p_less) as Total"))->where('user_id', Auth::user()->id)->first();

now I am goin to gett all data of users in a single admin page. so I am using following code in controller

public function users_list()
{
    $ptitle = "Website Users";
    $pdesc = "";

    $total_users = User::count();


    $users = User::select('*')->orderby('created_at', 'desc')->get();

        return view('admin.all-users-list',
                        ['ptitle' => $ptitle,
                        'pdesc' => $pdesc,
                            'users' => $users,
                            'total_users' => $total_users,
                        ]);
}

And folloing foreach loop to fetch users data in view page

<table class="table table-hover">
                            <tbody><tr>
                                <th>ID</th>
                                <th>User Name</th>
                                <th>Email</th>
                                <th>Country</th>
                                <th>Date</th>
                                <th>Points</th>
                            </tr>

                            <?php foreach ( $users as $u ){ ?>

                            <tr>
                                <td>{{ $u->id }}</td>
                                <td>{{ $u->user_name }}</td>
                                <td>{{ $u->email }}</td>
                                <td>{{ $u->country }}</td>
                                <td>{{ $u->created_at }}</td>
                                <td>????</td>
                            </tr>



                            <?php }?>

                            </tbody></table>

and result on view is as in this image

now I dont now that how can I fetch net points from points table for every user. please provide me some help to solve this issue.

Answer 1

you can make public function and call it every loop in foreach loop. Or create static function on the Points model class to get points for every user by using user_id as argument. Put getUserPoints on Points model class

public static function getUserPoints($userId){
    $points = self::select(DB::raw("sum(p_add)-sum(p_less) as Total"))
                      ->where('user_id', $userId)->first();
    if( $points != null ){
       return $points->Total;
    }
       return 0;

    }
}

And you can call it every loop as {{ \\App\\Points::getUserPoints($u->id) }}
