You are right, this is only true of Django queries :) On Jan 23, 6:33 pm, djidjadji djidja...@gmail.com wrote: This is not true. They are equivalent. They modify the query IN-PLACE.

At any point, if you want to know the value of the type variable you need to pass it to your handler You have at least 3 ways of doing so: 1. having a dedicated handler with a dedicated URL 2. passing the variable as a GET parameter (/directorysubmithandler? dir_type=...) 3. passing the variable as a POST parameter (adding input type=hidden name=dir_type value=... inside your form) to do 2 and 3 you just need to change the output of the handle that returns the form's page On Jan 23, 11:02 pm, Zeynel azeyn...@gmail.com wrote: On Jan 23, 3:12 am, ClaudeVedovinicla...@vedovini.net wrote: to do that you need to have your form action posted to /dir?type=xxx I have action=/directorysubmithandler I don't understand why form handler needs to be the final url.

Also, this is the mapping I use:
('/dir', DirectoryHandler),
Thanks.

I am still trying to resolve the question that I asked
here:http://groups.google.com/group/google-appengine/browse_thread/thread/...
I tried to use only one handler instead of two.
The new DirectoryHandler is here:http://pastebin.com/7RX32R6D
On line 40 I test if title of the form is empty
if empty form is not submitted and I get the merchandise_type from the
database and display by points.
This part works but else part does not work. On line 57 I try to write
form info to database:
else:
def post(self):
merchandise_type = self.request.get(type, )
item = Item()
item.title = self.request.get(title)
item.url = self.request.get(url)
item.type = merchandise_type
item.user_who_liked_this_item = user
item.put()
If the form is submitted the /dir is displayed without the url
parameters.
else part is never executed. I would appreciate help with this. Or the
best way to solve this problem. Thanks!
