Re: [google-appengine] Re: How to use the same variable in two handlers?
With what you want to do there IS NO difference in doing it in Django templates then in Mako templates. That will result in a hatred awards Mako too. 2011/1/23 Zeynel : > Unfortunately, I have an irrational hatred for Django templates so I > am trying to do this with Mako templates. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] Re: How to use the same variable in two handlers?
If you're trying to do this using Mako templates, here is a fully
functional 'demo' that you should be able to easily adapt to do
exactly what you're asking about.
app.yaml
handlers:
- url: /makodemo.*
script: makodemo.py
login: admin
makodemo.py
---
#!/usr/bin/env python
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from mako.lookup import TemplateLookup
from mako import exceptions
class DemoMakoTemplateHandler(webapp.RequestHandler):
"""Simple demo using mako templates."""
def __init__(self, **kwargs):
webapp.RequestHandler.__init__(self, **kwargs)
self.template_values = {'message': ''}
def render(self, template_name, values=None):
"""Setup search paths, and render the template.
Any values passed in will be combined with
self.template_values, and passed to the template.
"""
directories = ['templates']
lookup = TemplateLookup(directories=directories)
template = lookup.get_template(template_name)
if values:
self.template_values.update(values)
try:
self.response.out.write(template.render(**self.template_values))
except:
self.response.out.write(exceptions.html_error_template().render())
def get(self):
"""Render the template."""
self.render("demo.mako")
def post(self):
"""Get the user's message then render the template again."""
message = self.request.get('message')
self.render("demo.mako", {'message': message})
def main():
application = webapp.WSGIApplication([('/makodemo', DemoMakoTemplateHandler)],
debug=True)
run_wsgi_app(application)
if __name__ == '__main__':
main()
demo.mako
-
Mako Demo
Last message was: ${ message }
Make sure you've went through the app engine getting started and
really looked at how things work carefully. No matter which template
language you chose, be sure to review their docs too.

So, if you are getting 'type=' twice, did you think about trying:
self.redirect("/dir?%s" % urllib.urlencode({ "type" :
self.request.get("dir_type") } ))

Re: [google-appengine] Re: How to use the same variable in two handlers?
urllib.urlencode() should be used to quote the parameter
If Directory() is processed after DirectorySubmitHandler() you can
NEVER get the merchandise_type variable.
And it is possibly handled in another app instance.
dir_type = merchandise_type # remove this line
dir_type is never used in DirectorySubmitHandler()
import urllib
self.redirect("/dir?%s" % urllib.urlencode({ 'type' :
self.request.get("dir_type") } )

Re: [google-appengine] Re: How to use the same variable in two handlers?
Hi Zeynel,
You'll have to show us how you are rendering the form. If you're
using template, just pass the value you get for type to your template
and print the value, like djidjadji said.
