I am having the same problem with a gae-boilerplate site.
ur_for is defined in basehandler.py as so...
def jinja2_factory(app):
j = jinja2.Jinja2(app)
j.environment.filters.update({
# Set filters.
# ...
})
j.environment.globals.update({
# Set global variables.
'csrf_token': generate_csrf_token,
'uri_for': webapp2.uri_for,
'getattr': getattr,
})
j.environment.tests.update({
# Set test.
# ...
})
return j
The error occurs randomly, but once it occurs the site is down for good.
Re-uploading to GAE fixes the problem temporarily.
