Description
i was reading about the "new" enums feature here:
https://docs.djangoproject.com/en/3.0/ref/models/fields/#enumeration-types
And wanted to utilize it. However i tried to use is to check for equality rather than in. That made it impossible to utilize before i realized that the returned type from the CharField is, naturally, a char, and that i could check for equality with in: self.year_in_school in self.YearInSchool.JUNIOR
This probably isn't the most beautiful thing though, and it wasn't really stated that this is the defacto way to check for equality (lest i use self.year_in_school in self.YearInSchool.JUNIOR.value.
It would be quite nice if the self.year_in_school type actually was of type ENUM, or atleast had documented how you could check for equality with them.
The current solution seems, sadly, hacky at best.
