I cannot retrieve the value of the variable "g_place" in the following
python script back from "add_place.html". "g_place" is effectively
sent to "add_place.html" in the "def get(self)" section of class
AddPlace, but "g_place" is not returned to the python script in the
"def post(self)" section of class AddPlace. "g_place" is sent to
"add_place.html" and placed in the var "iwform" with the phrase
{{place|escape}}.
(I hope I have provided enough information. I am reluctant to upload
this buggy version to GAE, so I cannot just provide a link. Please
advise if there is another protocol/procedure I should be using to
provide the code as a link.)
Thanks,
Brian in Atlanta
