Why are @valid_attrs @update_attrs and @invalid_attrs using atom/declared-types keys while controllers will pass along stringified params?

Imo params should never be touched before they’ve gone through a changeset. It doesn’t need to be a schemas changeset and it doesn’t need persistance, but it should go through a changeset. Personally I even feel this can belong in the controller as opposed to in a context.

Hi @LostKobrakai! I don’t mean to highjack the thread, but now you got me curious…
I have to be honest and say that is quite “natural” given the way that the project is scaffolded to just patch the params since they are the common denominator in both controllers, contexts, and schemas. So I wonder what are you doing in cases where you want to use part of the data from the params and compute the rest of the fields in the program before they get cast.

I have another thread dedicated to this subject, would you mind sharing your experience there?
