Django ModelForm with extra fields that are not in

Question

I have done a ModelForm adding some extra fields that are not in the model. I use these fields for some calcualtions when saving the form.

The extra fields appear on the form and they are sent in the POST request when uploading the form. The problem is they are not added to the cleaned_data dictionary when I validate the form. How can I access them?

In Django 2 you can just add the fields as it was a normal form

class CreateCompanyForm(forms.ModelForm):

    password_confirmation = forms.CharField(
        label=translate('Password confirmation'),
        max_length=70,
        widget=forms.PasswordInput(),
        required=True,
    )
    company_name = forms.CharField(
        label="Nombre de la Compañía",
        max_length=90,
        widget=forms.TextInput(),
        required=True,
    )

    class Meta:
        model = AppUser
        fields = (
            "email",
            "first_name",
            "last_name",
            "password",
        )
