Django - The 'image' attribute has no file associated with it

User can register without a profile image. Now I get error that no file was associated with the login.

Why does it validate the form and then try to save the image?

It should not check for the image.

Traceback:

accounts/models.py

class UserProfile(models.Model):
        image = models.ImageField(upload_to=upload_image_path,null=True,blank=True)

    def save(self, *args, **kwargs):
    super(UserProfile,self).save(*args, **kwargs)
    if self.image != None:
        img = Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.image.path)


def post_save_user_receiver(sender, instance, created, *args, **kwargs):
    if created:
        new_profile = UserProfile.objects.get_or_create(user=instance)

The registration works without the user having a image, but the login does not.

Thank you for any help

According to traceback, there is a signal receiver in accounts/views.py#115, that listens for user_logged_in signal and tries to save user profile:

File "/usr/local/lib/python2.7/dist-packages/django/contrib/auth/__init__.py" in login
  161.     user_logged_in.send(sender=user.__class__, request=request, user=user)
...
File "/home/django/django_project/accounts/views.py" in got_online
  115.     user.profile.save()

And in user profile save and tries to open the profile image to thumbnail it.

I solved it by adding a default image to the file field:

image               = models.ImageField(upload_to=upload_image_path,default='default.jpeg')

and by changing the if statement in the save method

from:

  if self.image != None:

to:

  if not self.image:
