Re: model form validation

Shawn,

thanks for hint, I'll give that a try. Also I have some questions, for my own clarification of things: 

1) using your method - would is_valid() retur true then?
2) in my form display I should hide the "takeoff" field then, correct?
3) I alredy tried to override clean_takeoff() - it didn't get called. Any ideas, why?


Axel.

Axel,

In your example, you're wanting to populate a DateTime field in a model, but you want to allow the user to enter a string which would be invalid for the field.

One way to do this is to add an additional field to your form.

Example, given your 'takeoff' field:

   1. Add a charfield named takeoff_str in your form definition.

   2. Add a method named clean_takeoff_str to your form definition.

       In this function, check to ensure that the string entered is a valid
       HHMM value, if not raise a forms.ValidationError.

       Then, create a valid datetime from the input, and set
       self.cleaned_data['takeoff'] equal to this value.
