Ok, here is the question. Imagine I have a ModelForm which have only two fields. like this one:
class ColorForm(forms.Form):
color_by_name = forms.CharField()
color = forms.IntegerField(widget = forms.Select(choices=COLOR_CHOICES))
So a user can either input a color name, a choose it from a list. Color is required, but that doesn't mean, that user should enter it manually. There do I put validation, so that my code checks if user selected color in dropdownlist and if not then he should write it manually?
