Go to the migrations folder and delete manually files that have 000*_lastAction_blah-blah type of name, you can delete, probably all, but 0001_initial.py file. After that run ./manage.py make migrations app_you_are_updateing, it should update your database.
need just delete your base and make migrations your app
Have you ran makemigrations appname yet?
NOT NULL constraint failed
This error usually means that a field that is required was not provided, but I can see that you have set the blank=True and null=True attributes in your image field.
