---------------------------------------+------------------------
On my Form's clean(), I'm getting the values of some fields from their
cleaned_data and check if they are empty and throw a ValidationError when
they are. When certain conditions are met, all the fields would be
readonly when editing. Initial saving works fine. But when I try to resave
a Form which the fields I needed to check are readonly, somehow it creates
a ValueError: 'Form' has no field named 'field_name', making me think that
when a field is readonly, it's value isn't being set on it's cleaned_data
or the Form "forgets" it's model's fields.
{{{
def clean(self):
start_date = self.cleaned_data.get('start_date')
end_date = self.cleaned_data.get('end_date')
if start_date is None:
raise forms.ValidationError({'start_date': ["Start date is
empty",]})
elif end_date is None:
raise forms.ValidationError({'end_date': ["End date is
empty",]})
}}}
The ValueError is thrown by the if start_date is None: line
