In the end I came up with a solution which seems a bit hacky but does
exactly what I want.
It looks like this:
def clean(self):
cleaned_data = super(Form, self).clean()
check = cleaned_data.get("check", None)
# ignore 'len' when 'check' is False
if not checkand "len" in self._errors:
del self._errors["len"]
return cleaned_data
one thing to note: "len" won't be available in cleaned_data but that's
just cool since it's not valid :)

You could remove "required=True" from 'len' and override clean() to
perform a multiple-field validation. (pretty much what Thomas mentioned)
len() will execute -- it will check to see if it's an integer. If you
just want to completely ignore it, then do exactly as Thomas said,
override. But you'll have to make sure you do the "Integer Validation"
check in your clean() method if you ignore that validation in clean_len().
clean__len():
return self.cleaned_data['len']

What I want is to validate the 'len' field only when
'check' is True.
I could define the clean method of the form and validate
the required,
min_value and max_value stuff only when 'check' is True
but the case when
someone types a non integer value into the input is still
there. How could I
skip that? That check is done by the IntegerField.
well, you could override clean_len() and not do anything in
it, and
then override clean() and do your check there.
I don't think that would help. The clean method of the Field
(IntegerField in this case) would still run.
