How to declare all fields optional

[mekanix]

We used to be able to create model with metaclass which made all fields optional. How can we do that with ormar>=0.20.0? To give more context, I'd like to implement PATCH method and I'm looking for a way to make all fields optional.

What do you mean how? You can still provide custom metadata as you did before?

But the fields are not optional. Ormar screams at me that fields are missing. What I would like to do is something like UserOptional = make_copy_and_make_fields_optional(User) and use UserOptional as argument to FastAPI endpoint. Am I missing something in the docs?

I solved it like this. It's good enough I just don't know what are the cons of this approach.
