在 Laravel v5.3 中加入多个表

Question

I'm having trouble to join with multiple table. At first, I just join 'profil_pengguna' table with 'users' table. (There is no problem) But then, it getting error when I want to join with another table which is 'activity_log' table because I want to use 'created_at' field (from activity_log table) in my index.blade

user_id and subject_id are fk for id (in users table).

In fact I'm still new to using Laravel. So my task is to add some requirements to the existing code. Hoping that someone can help/guide me:) thanks in advance.

Here's my code in UserController

public function index()
    {
        $users = $this->userRepository->createModel()->with('roles')
            ->leftjoin('profil_pengguna', 'users.id', '=', 'profil_pengguna.user_id')
            ->leftjoin('activity_log', 'users.id', '=', 'activity_log.subject_id');

        if(Input::has('nama')) {
            $users->where('profil_pengguna.nama','like','%'.Input::get('nama').'%')->orWhere('email','like','%'.Input::get('nama').'%')->orWhere('no_mykad','like','%'.Input::get('nama').'%');
        }

        if(Input::has('status')) {
            $users->where('users.status','=','%'.Input::get('status').'%');
        } else {
            $users->where('users.status','=','1');
        }
            $users = $users->orderBy('users.id', 'desc')->paginate(10);

               Session::put('users_url',request()->fullUrl());
            //    echo session::get('users_url');

        return view('Centaur::users.index', ['users' => $users]);
    }

code for index.blade

<div class="panel-body">
                <div class="option pull-right" id="option" style="padding:5px; margin-bottom:5px;display:none;" >
                {!! Form::open(['route' => 'users.index', 'class' => 'form-inline', 'method' => 'GET']) !!}
                <div class="form-group">
                {!! Form::text('nama', null, ['class' => 'form-control', 'placeholder' => 'Nama / Email Pengguna / Kad Pengenalan']) !!}
                @if ($errors->has('nama')) <span class="help-block"> {{ $errors->first('nama') }} </span> @endif
                </div>
                <div class="form-group">
                {!! Form::select('status', ['0' => 'Dipadam', '1' =>'Aktif'], null, ['class' => 'form-control', 'placeholder' => 'Sila pilih...']) !!}
                @if ($errors->has('status')) <span class="help-block"> {{ $errors->first('status') }} </span> @endif
                </div>
                <button type="submit" class="btn btn-primary">
                Cari
                </button>
                {!! Form::close() !!}
                </div>
                <div class="clearfix"></div>

Hi By Carefully looking at your code and the table structure which you havent shared, so supposing it this way that table name is users and it contains id as primary key, the updated code is this

$users = $this->userRepository->createModel()->with('roles')
            ->leftjoin('users', 'users.id', '=', 'profil_pengguna.user_id')
            ->leftjoin('users', 'users.id', '=', 'activity_log.user_id');

Might be another possibility where you are saving subject_id in activity log table so you need to add one more join with subject masters table

$users = $this->userRepository->createModel()->with('roles')
            ->leftjoin('users', 'users.id', '=', 'profil_pengguna.user_id')
            ->leftjoin('users', 'users.id', '=', 'activity_log.user_id')
->leftjoin('subject', 'subject.id', '=', 'activity_log.subject_id');
