Question

Models.py:

class ItemImage(Model):
    image = ImageField(upload_to=get_user_upload_path)

Forms.py:

class ItemImageForm(ModelForm):
    class Meta:
        model = ItemImage

Say, I initialized an ItemImageForm with an instance of ItemImage and added the form as img_form to the context used for rendering the template with. I know that I can access the corresponding ItemImage instance with img_form.instance. But I am curious if there’s a more direct way to access ItemImage.image from its corresponding img_form.image?

Answer 1

It shouldn’t be accessed at all. The form consists of initial data and cleaned data. If you refer to initial data, use instance. If you need value after user’s action, call is_valid or full_clean and later look for value in cleaned_data. Everything in between is hacking.

If you want to perform any special cleaning on img_form.image, create clean_image method, but you’re probably aware of that already.
