Add extra key in laravel eloquent result - php

Question

I have a laravel query builder result that looks like this
{
"data": [
{
"id": "",
"awardID": 2,
"title": "Dummy title",
"status": "active",
"raceStart":"",
"raceEnd:":""
}
]
}
What i want to output is something like this
{
"data": [
{
"id": "",
"awardID": 2,
"title": "Dummy title",
"status": "active",
"period": {
"raceStart":"",
"raceEnd:":""
}
}
]
}
This would have been much easier if the period was a table with a 1 to 1 relationship with parent table but this is not the case here.
How can this be achieved?

Answer 1

Check if this will work. I haven't tried though but according to documentation we can add accessor and mutators. But it will change every response you are doing with the model.
Using Eloquent
// Your Model
class Race extends Model
{
{...}
protected $appends = ['period'];
// accessor
public function getPeriodAttribute($value)
{
$this->attributes['period'] = (object)[];
$this->attributes['period']['raceStart'] = $this->attributes['raceStart'];
$this->attributes['period']['raceEnd'] = $this->attributes['raceEnd'];
unset($this->attributes['raceStart']); = $value;
unset($this->attributes['raceEnd']);
return $this->attributes['period'];
}
}
Now when you will access $race->period will give the raceStart and raceEnd value.
Ref: https://laravel.com/docs/5.4/eloquent-mutators#accessors-and-mutators
else another option is after query, do a map
{...}
->map(function($data) {
$data->period = (object)[];
$data->period['raceStart'] = $data->raceStart;
$data->period['raceEnd'] = $data->raceEnd;
unset($data->raceStart);
unset($data->raceEnd);
return $data;
});
Ref: https://laravel.com/docs/5.4/eloquent-collections#introduction
Using QueryBuilder
$races = DB::table('races')->get();
$races = array_map(function ($data) {
$data->period = (object)[
"raceStart" => $data->raceStart,
"raceEnd" => $data->raceEnd
];
unset($data->raceStart);
unset($data->raceEnd);
return $data;
}, $races->data);
