Question 1

Which base class should be used to create a simple Django form (not tied to a model)?

Accepted Answer

The forms.Form class is the base class for creating Django forms independent of any model. It allows manually defining each field with its type and validators. ModelForm is only used when binding the form directly to an existing Django model.

Question 2

How to access validated data from a Django form after calling is_valid()?

Accepted Answer

The cleaned_data attribute is a dictionary containing form data after validation and cleaning. It is only available after a successful call to is_valid(). Values are converted to appropriate Python types (for example, a date string becomes a datetime.date object).

Question 3

In a ModelForm, which Meta class attribute specifies the model to use?

Accepted Answer

The model attribute in a ModelForm's Meta class defines the Django model the form will be based on. Django automatically generates form fields corresponding to the specified model's fields. The fields or exclude attributes then control which fields to include.
