AttributeError: 'thread._local' object has no attribute 'request'
So no, it doesn't work :) Keep in mind that the form is being
built at compile time, not request time.
I found a google hit about allowing default to be a callable in
ToscaWidgets. Guess there's been no similar fix to TG widgets, at least
not in 1.0.1. I subclassed HiddenField and overrode adjust_values to
allow it:
class FixedHiddenField(HiddenField):
def adjust_value(self, value, **kw):
value = super(FixedHiddenField,self).adjust_value(value, **kw)
if callable(value): value = value()
return value
form = TableForm(
fields=fields+[FixedHiddenField(name='referer',
default=lambda: request.headers['Referer'])])
Now my forms are happy :)
