[html-formfu] defaults_from_model doesn't call deflators

[Moritz Onken]

Hi.

it's HTML::FormFu::Deflator::Strftime not  
HTML::FormFu::Deflator::DateTime which allows me to stringify the  
DateTime object to a string which fits to the locale of the user.
I can't do this with DBIC because I have no access to the $c->user  
object there (using catalyst)

As a diagram (thanks to Brian ;-) )


+------+ <---- (FormFu Strftime deflator) +------------+ <---- ( DBIC  
DateTime inflator ) ---- +-------+
| FORM |                                  | Controller  
|                                       | MODEL |
+------+ ----> (FormFu DateTime inflator) +------------+ ----- ( DBIC  
DateTime deflator ) ---> +-------+

I do not call $form->render because I use FormFu to create a JSON file  
to load a form using ExtJS. FormFu does all the validation etc. but  
doesn't render the form itself.

What do you think about adding a method like $element->deflated_value  
or $element->deflated_default?
