add new attribute to laravel eloquent collection

Question

I would like to push in my eloquent model an extra attribute on calculation and I would like to use it in my blade as $user->avatarImg my model method look like

 public function avatarImg()
 {

     if($this->hasMedia('avatar')) {
         $image = $this->getMedia('avatar');
         $img = \Intervention\Image\ImageManagerStatic::make($image[0]->getPath())->encode('data-url');
     }
     elseif ($this->blob->file) {
         $img = 'data:image/jpeg;base64,'. base64_encode($this->blob->file);
     } else {
         $img = '';
     }


     $this->user->put('avatarImg', $img);

     dd($this->user);

     return $img;

 }

but what I try does not working I get:

Call to a member function put() on null

how would I do this properly?

Looks like property user does not exists in your model. If this is User model try just

$this->put('avatarImg', $img);

Thanks for feedback. Tried previously does not work either ``Call to undefined method Illuminate\Database\Query\Builder::put()`` – deroccha Sep 16 '17 at 10:24
Try maybe $this->avatarImg = $img; – Leonid Serdiuk Sep 16 '17 at 10:26
$collection = new Collection(array($this)); $collection->put('avatarImg', $img); – Leonid Serdiuk Sep 16 '17 at 10:30
doing like that would not modify the models attributes, I do after dd(Auth::user()) but I do not see the new attribute – deroccha Sep 16 '17 at 10:37
try this https://stackoverflow.com/questions/39898954/define-custom-attributes-in-eloquent – Leonid Serdiuk Sep 16 '17 at 10:43
I know this workaround but in case of api calls where I need as json the attribute value would not work – deroccha Sep 16 '17 at 10:45
