Laravel: override eloquent function for get results? - laravel

Question

I can override function before save :
public function save(array $options = [])
{
if(isset($this->datesConvert)){
foreach($this->datesConvert as $date){
$this->attributes[$date] = Carbon::createFromFormat('d/m/Y', $this->attributes[$date])->format('Y-m-d');
}
}
parent::save($options);
}
But which method I can use for get result ? and where is documentation for this. I am looking for something like :
public function get()
{
parent::get();
if(isset($this->datesConvert)){
foreach($this->datesConvert as $date){
$this->attributes[$date] = Carbon::createFromFormat('Y-m-d', $this->attributes[$date])->format('d/m/Y');
}
}
}
With that I can convert 10 date rows without need of 20 mutators..

Answer 1

It seems that Attribute casting fits your needs or use Date mutators
You may customize which fields are automatically mutated, and even completely disable this mutation, by overriding the $dates property of your model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* The attributes that should be mutated to dates.
*
* #var array
*/
protected $dates = [
'created_at',
'updated_at',
'deleted_at',
// more dates
];
}
EDIT
Another way, you can override getAttribute method in Model
<?php
namespace App;
use Carbon\Carbon;
trait DateFormatting
{
protected function dateFields()
{
return [];
}
public function getAttribute($key)
{
if ( array_key_exists( $key, $this->dateFields() ) ) {
return Carbon::createFromFormat('d/m/Y', $this->attributes[$key])->format('Y-m-d');
}
return parent::getAttribute($key);
}
}
then you can use this trait in any your model, just don't forget override dateFields in it
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use App\DateFormatting;
class User extends Model
{
use DateFormatting;
protected function dateFields()
{
return [
'finished_at',
// other field names that you need to format
];
}
after all you can access to this fields as usual(using magic __get())
$model->finished_at;

I find a solution, My solution is :
public function save(array $options = [])
{
if(isset($this->datesConvert)){
foreach($this->datesConvert as $date){
$this->attributes[$date] = \Carbon\Carbon::createFromFormat('d/m/Y', $this->attributes[$date])->format('Y-m-d');
}
}
parent::save($options);
}
public function getAttribute($key)
{
$value = parent::getAttribute($key);
if(isset($this->attributes[$key])){
if(isset($this->datesConvert) && in_array($key, $this->datesConvert)){
$value = \Carbon\Carbon::createFromFormat('Y-m-d', $value)->format('d/m/Y');
}
}
return $value;
}

Laravel comes with something very useful for this problem. I'm not sure what it's called, but you can modify attributes or even add new attributes like this:
class YourModel extends Model
{
...
public function getDateAttribute()
{
return Carbon::createFromFormat('Y-m-d', $this->attributes[$date])->format('d/m/Y');
}
...
}
You can retrieve this attribute like:
$yourModel->date;
Edit after comment #fico7489
You can't ignore the fact you always have to modify things. However there are still some solutions to make it easier.
For example you can change your date column to a string and just store your date with the desired date format.
Other solution should be modifying the date through sql. FORMAT(Now(),'YYYY-MM-DD').
Example in laravel would look like (not tested):
YourModel::select([
'*',
DB::raw('
FORMAT(yourDateColumn,'YYYY-MM-DD')
')
])->get();
