Description
It would be helpful to show an example of how to implement your own clean_fieldname() and clean() methods for subclassed forms. (N.B. An example of how to clean a subclassed field IS shown - ie field.clean(self, value))
Presumably cleaning should be done by using the .data attribute of forms, although .data doesn't appear to be documented.

All you need to know is here:
http://www.djangoproject.com/documentation/newforms/#custom-form-and-field-validation
But, you are right an example of Form.clean() would be good. I took this one
from tests/regressiontests/forms/forms.py.
The patch is attached.

Note:
See TracTickets
for help on using tickets.
Cleaning should not be done using .data, as custom functions run after the default.
As such,
cleaned_datawill already be populated for the field(s) in question, and should be used instead :)
