Please help me. I am new to Django, cannot undertsand the following. I have
subclass of CreateView for creating a post. I'm creating a rental site
project where people can post their apart and attach files (images) to it.
One should have possibility to attach as many images as he wants to ONE
form. I have found in Internet a decision that I need to use 2 models - 1
model for post + 1 separate model for images. Is it so?
Post form is created and handled in my views.py by sublass of CreateView.
Now how to connect new separate model for images with my CreateView ? And
save all images to the current Post Form?
Thanks in advance
