How to display all row in database - Laravel 5.2?

Question

I have simple issue with my Laravel application.But i can not find any solution of it.Please see my code here:

controller:

public function index(){
    $members = Member::paginate(15);

    $meal_entry = Member::all();
    $breakfast = DB::SELECT("SELECT self_meal_breakfast + guest_meal_breakfast AS breakfast FROM meal_entry");
    $lunch = DB::SELECT("SELECT self_meal_lunch + guest_meal_lunch AS lunch FROM meal_entry");        
    $dinner = DB::SELECT("SELECT self_meal_dinner + guest_meal_dinner AS dinner FROM meal_entry");
    $total_meal = DB::SELECT("SELECT self_meal_breakfast + self_meal_lunch + self_meal_dinner + guest_meal_breakfast + guest_meal_lunch + guest_meal_dinner AS total FROM meal_entry");

    return view('member.mealView', compact('members','data','breakfast','lunch','dinner','meal_entry','total_meal'));
}

blade view:

<tbody>
    <tr>
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach                                        
        @foreach($breakfast as $value)
        <td>{{ $value->breakfast }}</td>
        @endforeach                                        
        @foreach($lunch as $value)
        <td>{{ $value->lunch }}</td>
        @endforeach                                        
        @foreach($dinner as $value)
        <td>{{ $value->dinner }}</td>
        @endforeach                                        
        @foreach($total_meal as $value)
        <td>{{ $value->total }}</td>
        @endforeach                                        
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach
    </tr>
</tbody>

And the table: meal_entry .

If there is a one row in the database then its ok ( see ) to view.But when there is row more than one then its show in one row with all data( see ).How can i handle this things? I think it should be run another loop but how can i do that? Thanks in advance.

Answer 1

So, if you're using Laravel, one of the best features that has is the accessors:

https://laravel.com/docs/5.2/eloquent-mutators#accessors-and-mutators

You can create new attributes and use them as model attributes.

For some stuff are very useful.

class Meal extends Model
{
    public function getTotalBreakfastAttribute()
    {
        return $this->self_meal_breakfast + $this->guest_meal_breakfast;
    }
}

And then, use this accessor as attribute:

<tbody>
   @foreach($foods as $value)
    <tr>
       <td> {{$value->total_breakfast}} </td> 
       <td> {{$value->created_at}} </td>
    </tr>
  @endforeach
</tbody>

Or if you don't want to do that, instead of use multiple queries to get the data, just use one because all the fields are in the same table, and then, you could use the above example.

Enjoy! :)

A quick patch would be to do only one query and then do the calculations on the view (I know that is not a good practice to do the calculations in the view, but is the easiest way that i can see).

It would be like this:

Controller:

public function index(){
    $members = Member::paginate(15);

    return view('member.mealView', compact('members'));
}

blade view

<tbody>
    @foreach($members as $meal_entry)
    <tr>
        <td>{{ $meal_entry->created_at }}</td>

        <td>{{ $breakfast = $meal_entry->self_meal_breakfast + $meal_entry->guest_meal_breakfast }}</td>

        <td>{{ $lunch = $meal_entry->self_meal_lunch+ $meal_entry->guest_meal_lunch}}</td>

        <td>{{ $dinner = $meal_entry->self_meal_dinner + $meal_entry->guest_meal_dinner }}</td>

        <td>{{ $breakfast + $lunch + $dinner }}</td>

        <td>{{ $meal_entry->created_at }}</td>
    </tr>
    @endforeach 
</tbody>

And remember to add

{{ $members->links() }}

Where you want the pagination links.
