Laravel weekly group by eloquent collection error - laravel

Question

I have orders table, and for each user weekly payments table.
I want to show user that he wil take total payment count on depending week.
I have created the query but on blade side, when i try to access other tables via eloquent it gives does not exits in this collection.
If i dont use group by function it works. But with group by function it doent
$earnings = user()->orders()->where('payment_status',0)-
>where('status',1)->get()->groupBy(function($date) {
return Carbon::parse($date->created_at)->format('W');
});
In blade side my codes like following;
#foreach($earnings as $earning)
<tr>
<td>{{$earning->user->name}}</td>
<td>{{$earning->order->commission}}</td>
<td>{{$earning->user->bank}}</td>
<td>{{$earning->user->iban}}</td>
<td>{{$earning->user->phone}}</td>
#endforeach

Answer 1

get() should be last:
$earnings = user()->orders()
->where('payment_status',0)
->where('status',1)
->groupBy('created_at')
->get();
How about using DATE_FORMAT function:
$earnings = user()->orders()
->where('payment_status',0)
->where('status',1)
->groupBy(DB::raw("DATE_FORMAT(created_at, '%W')"))
->get();

Answer 2

Assuming your table is orders, you can do like this:
$earnings = user()->orders()->select('orders.*', DB::raw("DATE_FORMAT(created_at, '%W') as week"))
->where('payment_status',0)
->where('status',1)
->get()->groupBy('week');

Answer 3

Laravel Collection groupBy() function returns a collection of grouped collections.
$earningGroups = user()->orders()
->where('payment_status',0)
->where('status',1)
->get()
->groupBy(function($earning) {
return Carbon::parse($earning->created_at)->format('W');
});
Now this is a collection of earning groups, not earnings.
#foreach($earningGroups as $earcningGroupName => $earcningGroup)
// So here you have a group or earnings
// I don't know why did you want to group.
// For an example I will print the group name as a table row here.
// But do whatever you want.
<tr>
<td>{{ $earningGroupName }}</td>
</tr>
// So if you want to loop through earnings, you have to loop again.
#foreach($earningGroup as $earning)
<tr>
<td>{{$earning->user->name}}</td>
<td>{{$earning->order->commission}}</td>
<td>{{$earning->user->bank}}</td>
<td>{{$earning->user->iban}}</td>
<td>{{$earning->user->phone}}</td>
</tr>
#endforeach
#endforeach
