Subject: newforms: [] not in EMPTY_VALUES
Print | Individual message | Show original | Report this message | Find messages by this author
hi,

i noticed that [] is not in the EMPTY_VALUES against which data is
validated in newforms fields' default clean() function; this makes
fields which usually return lists raise the ValidationError 'This field
is required.' themselves instead of relying on super(). an example of
this behavior is the MultipleChoiceField (newforms/fields.py:376).

is this intended behavior or just a leftover from some earlier stage?
why isn't the boolen representation used instead? (`if self.required and
not value:` instead of `if self.required and value in EMPTY_VALUES:`)?

regards
webograph

I cannot say whether it's right or wrong since I haven't done anything with
newforms (yet). From what you write, it looks like a but. Would you mind
opening a ticket on the ticket system, so that this doesn't get lost
accidentally?

So long,

Michael
