One important thing we forgot to mention.
TG 0.9a5 ships with FE 0.5.1 that fixes some long standing issue with
how not_empty works inside validators, basically this means that now
*every* validator has not_empty=False by default, this was the case
even before but now this is respected hence if you were using a
validator like Int() and not providing not_empty to mark it as required
you should now take care of doing this.
Example:
>>> from turbogears import validators
>>> int = validators.Int()
>>> int.not_empty
False
>>> int.to_python('')
>>> int.not_empty = True
>>> int.not_empty
True
>>> int.to_python('')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"/home/michele/Progetti/TurboGears/svn/1.0/thirdparty/formencode/formencode/api.py",
line 305, in to_python
raise Invalid(self.message('empty', state), value, state)
formencode.api.Invalid: Please enter a value
>>>
While before 0.9a5 using Int() and to_python('') will have raised a
"Please enter an integer value" exception.
Another handy feature related to this is that now it's pretty easy to
tweak some defaults parameter for such form fields that are already
providing a validator, for example if you use any SelectionField
(SingleSelectField, MultipleSelectField, CheckBoxList, RadioButtonList)
the validator is automatically guessed and not required by default, if
you want to mark the field as required without passing a whole new
validator you can pass a dict as validator in this way:
widgets.MultipleSelectField(..., validator=dict(not_empty=True))
