Re: django form data not saving to database

models.OneToOneField(Category,default='category')

This is not set in form and not set in view and is not null so when you do post.save() error was raised and post is not saved.

I don't sure that you can pass str as default for OnetoOne and I am not sure that you need a OnetoOne field I think foreignkey us better for you, because have not sense have one category for every post, I think you want several post in one category.
