Hello,
I've just found a QR-Code reader that adds a variable to the encoded URL
before passing it to the navigator and this variable is
"mobiletag-title=http%3A%2F%2Fwww...etc....".
The problem is that TG tries to decode that variable through
formencode/variabledecode/variable_decode which is not pleased by the "-"
...
What can I do to solve this issue ? Any suggestion ?
(changing the QR-Code reader is not an option as the TG application is
supposed to be used by anybody)
I think your best option is to install a filter that alters the request so that
the attribute name "mobiletag-title" gets re-mapped to e.g. mobiletag_title.
Yes, but the issue is that I cannot predict what parameter name a new
tool can invent... :-(
I found another way to get it right :
patch turbogears.filters.base.py to add a exeption handler to the filter.
class NestedVariablesFilter(object):
"""Request filter that turns request params with names in special
dotted
notation into nested dictionaries via FormEncode's NestedVariables
validator.
"""
def before_main(self):
if hasattr(request, 'params'):
try:
request.params =
NestedVariables.to_python(request.params or {})
except ValueError, e:
log.warning(u'ValueError: %s' % e)
So : if it can't decode nested variables, it lets the parameter as-is...
What do you think about that ?
