As already explained, if the checkbox is not set, then there will be no
field with that name. So you need to check whether the field exists at
all. If it is set, then there will be a field with that name and the
value as defined in the input tag. If you have several check boxes with
the same name, and more than one of them are checked, it will be a list
with all these values. So you may need to check the type as well.

Instead of the first line, you can also write,
if self.request().hasField('Donit'):
Or, as Michel suggested, you can replace all 4 lines with:
f1 = self.request().field('Donit', None)

The complete HTML documentation is installed together with Webware.
The starting page is Docs/index.html; it is the same as the online Docu
at http://www.w4py.org/Docs/
Click on "Component Index", then "WebKit". There you have the manuals
and tutorials for WebKit, the main Webware component. There is also a
class and file list for the Python modules belonging to WebKit. For a
first orientation, the summaries are helpful. For instance, you will
find the methods for accessing fields listed under ## Fields ## here:
http://www.w4py.org/WebKit/Docs/Source/Summaries/HTTPRequest.html
Hope that helps.
