Modify all attributes of a Laravel model - laravel

Question

Accessors will do their job on a single attribute perfectly, but I need a way to have a method to do an Accessor/Getter job on all attributes and automatically.
The purpose is that I want to replace some characters/numbers on getting attributes and then printing them out. I can do it from within controller and manually but I think it would be great to have it from model side and automatically.
Like overriding getAttributes() method:
public function getAttributes()
{
foreach ($this->attributes as $key => $value) {
$this->attributes[$key] = str_replace([...], [...], $value);
}
return $this->attributes;
}
But I have to call it every time on model $model->getAttributes();
Any way to do it automatically and DRY?

Answer 1

Try something like:
public function getAttribute($key)
{
if (array_key_exists($key, $this->attributes) || $this->hasGetMutator($key)) {
if($key === 'name') return 'modify this value';
return $this->getAttributeValue($key);
}
return $this->getRelationValue($key);
}
It's fully overriding the default method so be a bit careful.

I would go with following approach and override the models __get method:
public function __get($key)
{
$excluded = [
// here you should add primary or foreign keys and other values,
// that should not be touched.
// $alternatively define an $included array to whitelist values
'foreignkey',
];
// if mutator is defined for an attribute it has precedence.
if(array_key_exists($key, $this->attributes)
&& ! $this->hasGetMutator($key) && ! in_array($key, $excluded)) {
return "modified string";
}
// let everything else handle the Model class itself
return parent::__get($key);
}
}

How about running it with each Creating and Updating events. So you can do something like that:
public function boot()
{
Model::creating(function ($model)
return $model->getAttributes(); //or $this->getAttributes()
});
Model::updating(function ($model)
return $model->getAttributes(); //or $this->getAttributes()
});
}
