Eloquent: get data for every day of the month - laravel

Question

I have some troubles with my Eloquent query result formatting.
I have the table Clubs and it stores football clubs. Every record in database has 'brand' value and now I want to return count of column brand values for every day. For example: I added today 9 times "Real" and 40 times "Barcelona" to my table, so I expect return value for every day in the last month like:
[
{
"date": "2019-01-12",
"clubs": {
"Barcelona": 40,
"Real": 9
}
}
]
Instead of that I get:
[
{
"date": "2019-01-12",
"count": 9,
"brand": "Real"
},
{
"date": "2019-01-12",
"count": 40,
"brand": "Barcelona"
}
]
There's my controller query:
$brandsMonthlyInfo = array();
$dates = collect();
foreach( range( -30, 0 ) AS $i ) {
$date = Carbon::now()->addDays( $i )->format( 'Y-m-d' );
$dates->put( $date, 0);
}
$countAddedBrands = DB::table('Clubs')->where([['created_at', '>=', $dates->keys()->first()]])
->groupBy( 'date' )
->groupBy( 'brand' )
->orderBy( 'date' )
->get( [
DB::raw( 'DATE( created_at ) as date' ),
DB::raw( 'COUNT(brand) AS "count"' ),
'brand'
] );
return $countAddedBrands;
Do you have any idea how to fix that? I really appreciate any help.

Answer 1

you can transform the data like this
$brandsMonthlyInfo = array();
$dates = collect();
foreach( range( -30, 0 ) AS $i ) {
$date = Carbon::now()->addDays( $i )->format( 'Y-m-d' );
$dates->put( $date, 0);
}
$countAddedBrands = DB::table('Clubs')->where([['created_at', '>=', $dates->keys()->first()]])
->groupBy( 'date' )
->groupBy( 'brand' )
->orderBy( 'date' )
->get( [
DB::raw( 'DATE( created_at ) as date' ),
DB::raw( 'COUNT(brand) AS "count"' ),
'brand'
] );
// create the array to contain the objects
$arrayOfAddedBrands = [];
foreach($countAddedBrands as $brand){
$found = 0;
// looping over the array to search for the date if it exists
foreach($arrayOfAddedBrands as $key => $brandFromArray ){
// if the date exists
if($brand->date == $brandFromArray->date){
// add the brand to the clubs object
$brandFromArray->clubs->{$brand->brand} = $brand->count;
$found = 1;
// assign the array element to the new modified object
$arrayOfAddedBrands[$key] = $brandFromArray;
break;
}
}
// if the date not found
if(!$found){
// create new object and assign the date to it
$brandObject = new \stdClass;
$brandObject->date = $brand->date;
// creating the clubs object
$brandObject->clubs = new \stdClass;
$brandObject->clubs->{$brand->brand} = $brand->count;
// adding the final object to the array
$arrayOfAddedBrands[] = $brandObject;
}
}
return $arrayOfAddedBrands;
