Unable to make correct migrations in Django
I cannot make correct migrations with one specific fields image_two in my Django Project. I have also configured Django-Rest and all this is connected to AWS. Endpoint is looking alright and I am getting correct url from image_one and image_two. But I don't know how to create a column in database for storage this image URL.

This is handy for a lot of reasons, but it means that the path to the image file needs to be programmatically constructed based on the source image and the spec.
