Ok, so, parts of this I can kind of help with. Sadly all this is is
more directions, rather than the map you're after, but perhaps it can
help.
class ReCaptcha(FormField):
template = """
<div xmlns:py="http://purl.org/kid/ns#";>
<script type="text/javascript" src="${api_server}/challenge?k=$
{public_key}"></script>
<noscript>
<iframe src="${api_server}/noscript?k=${public_key}"
height="300" width="500" frameborder="0"></iframe><br />
<textarea name="recaptcha_challenge_field" rows="3"
cols="40"></textarea>
<input type='hidden' name='recaptcha_response_field'
value='manual_challenge' />
</noscript>
</div>
"""
def update_params(self, d):
super(ReCaptcha, self).update_params(d)
d['api_server'] = config.get('recaptcha.api_server')
d['public_key'] = config.get('recaptcha.public_key')
This is a custom formfield, you can see the use of a variety of
related bits and pieces, it works in conjunction with a custom
validator.
The main trick, from your perspective, is the template. You can see
it's a full kid template and I could have changed the formatting
depending on a custom or standard variable. You'll notice the use of
update_params to add the api_server and public_key pieces to the
parameters, but you can also access any parameters passed in at widget
creation at the same time.
I *think* this answers what you're asking about, but perhaps not.
Please feel free to ask for more details or whatever, I have a growing
pile of custom stuff like that as part of my regular base setup so I
can probably find other examples if needed.
