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 azeyn...@gmail.com: 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.

I have the hidden field in the form in Directory like this: input type=hidden name=dir_type value=merchandise_type but how do I get that the value of the merchandise_type in the DirectorySubmitHandler? self.request.get(dir_type) is merchandise_type not the url parameter?

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.

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) } )

'type' is between quotes == a string. Has nothing to do with a variable or a function object. -- 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?
So, if you are getting 'type=' twice, did you think about trying:
self.redirect(/dir?%s % urllib.urlencode({ type :
self.request.get(dir_type) } ))

I understand this. If I use this solution the url is always
/dir?type=type=
type is not replaced with the merchandise_type. Maybe I am not using
it correctly?

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
-
html
head
titleMako Demo/title
/head
body
divLast message was: ${ message }/div
form action=/makodemo method=post
input type=text name=message value=${ message }/input
input type=submit name=doit value=update/input
/form
/body
/html
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.

Yes, actually I thought about that but I did not try it because I did
not get
/dir?type=type=tshirt
but just /dir?type=type=
without the url parameter. But I may be wrong so I will try. But now I
am working on trying to make this work with templates as explained
here:
http://stackoverflow.com/questions/4769063/how-do-i-pass-url-parameter-to-form-value
Unfortunately, I have an irrational hatred for Django templates so I
am trying to do this with Mako templates. Researching this I found an
old answer of yours:
http://stackoverflow.com/questions/3938963/mako-templates-with-google-app-engine/3939208#3939208.
Thanks again for that answer. At this point my template page is
printing as text like this
�html �body �pRender template�/p ${greeting} �/body �/html
so I am going to try to fix that first and then try the urllib option.
