laravel/eloquent mutators/accessors in a pivot table - php

Question

Well, I think the title explains most of it. Lets get right into it!
Blank Model:
class Blank extends Eloquent
{
protected $table = 'blanks';
protected $softDelete = true;
protected $hidden = array();
/**
* Get associated jobs.
*
* #return mixed
*/
public function jobs()
{
return $this->belongsToMany('Job')->withPivot('status', 'inventory', 'sizes', 'mill', 'po', 'location', 'ordered_at', 'expected_at', 'note')->withTimestamps();
}
/**
* Blanks sizes accessor
*
* #return object
*/
public function getSizesAttribute($value)
{
return json_decode($this->pivot->sizes);
}
/**
* Blanks sizes mutator
*
* #return void
*/
public function setSizesAttribute($value)
{
$this->pivot->attributes['sizes'] = json_encode($this->pivot->sizes);
}
}
Job Model:
class Job extends Eloquent
{
protected $table = 'jobs';
protected $softDelete = true;
protected $hidden = array();
/**
* Get associated blank.
*
* #return mixed
*/
public function blanks()
{
return $this->belongsToMany('Blank')->withPivot('status', 'inventory', 'sizes', 'mill', 'po', 'location', 'ordered_at', 'expected_at', 'note')->withTimestamps();
}
/**
* Blanks sizes accessor
*
* #return object
*/
public function getSizesAttribute($value)
{
return json_decode($this->pivot->sizes);
}
/**
* Blanks sizes mutator
*
* #return void
*/
public function setSizesAttribute($value)
{
$this->pivot->attributes['sizes'] = json_encode($this->pivot->sizes);
}
}
Attaching Code:
$job->blanks()->attach($blank->id,[
'status' => Input::get('status'),
'inventory' => Input::get('inventory'),
//'sizes' => $sizes,
'mill' => Input::get('mill'),
'po' => Input::get('po'),
'location' => Input::get('location'),
'ordered_at' => Carbon::parse(Input::get('ordered_at'))->format('Y-m-d H:i:s'),
'expected_at' => Carbon::parse(Input::get('expected_at'))->format('Y-m-d H:i:s'),
'note' => Input::get('note'),
]);
The mutator is not being called at all.. Any ideas?

Seems like that not possible to do this through ::attach() method.
But maybe you would like to use 'Defining A Custom Pivot Model'
public function newPivot(Model $parent, array $attributes, $table, $exists)
{
return new YourCustomPivot($parent, $attributes, $table, $exists);
}
So, you can define your own pivot class with mutators:
class BlankJobPivot extends Eloquent
{
// ...
/**
* Blanks sizes accessor
*
* #return object
*/
public function getSizesAttribute($value)
{
return json_decode($value);
}
/**
* Blanks sizes mutator
*
* #return void
*/
public function setSizesAttribute($value)
{
$this->attributes['sizes'] = json_encode($value);
return $value; // return for multiple assignment statement: $arr = $pivot->sizes = array(12, 23, 34);
}
}
And than you can use getters:
$blank->jobs[$i]->pivot->sizes; // - ::getSizesAttribute() will called ( I hope :) )
And maybe you will find a way to save / attach through the setSizesAttribute mutator.
Good luck.
