Подскажите, как вывести данные на страницу?
Пишу погодное приложение и вроде все работало, а потом перестало выводить в самом приложении . В базу данных все добавляет, но выводит только сломанный шаблон.

Does property decorator method run whenever an object is accessed?
Suppose this is a class: class A(models.Model): user_id = models.UUIDField() date = models.DateField() def __str__(self): return f"({self.pk})-({self.user_id})-{self.date}" @property def related_day(self): return RelatedDay.objects.filter(user_id=self.user_id, date=self.date).first() My question is, if I access an object of class A, will the related_day() method be called everytime? Or it will be called only when I access A.related_day? I don't want to take any performance hit for using property decorator when I don't need related day. I've read these answers but I'm not sure yet about this. -

Creating a form that updates only 1 field of an entry
I am currently trying to create a checklist that would print a customer database. this checklist would print all the customers for a specific service - in this case, its IT14's- and it would let the user update the checklist field (isdone_IT14) However, the error I am running into at the moment, is that the form is not valid due to the fact that the rest of the fields are required. It looks like when the checklist is ticked, the form is trying to create a new entry. How would I fix that issue so that it only updates the field for that one entry?

signal for custom user registration in django
