How to pass dynamic fields to save()?

Question

Django

There are 4 fields that are not in the database and not in the model, I need them when a certain status is selected.
That is, the required fields when choosing a status.

forms.py
  delivery= forms.CharField(required = False, label = u"Доставка", widget=forms.TextInput(attrs={'size':40}))

model.py
   def save()
     как сюда вывести request.POST
???

Answer 1

Offhand - your form has a save method. This is where you accept your fields in cleaned_data, and pass the required field to the save() method of the model.
This is better than trying to push request directly into the model.
