[google-appengine] Re: Need Python example of Template System

[Gillwill]

Oops!

Of course the code under "def get(self):"  should be indented
accordingly.




= = = = = = = = = =

How about this (assumes you have the "helloworld.html" stored in the
"templates" subfolder of where your code is)

for main.py:

from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from google.appengine.ext.webapp import template

class MainHandler(webapp.RequestHandler):
def get(self):
template_values = { 'textMessage': 'Hello World', }
path = os.path.join(os.path.dirname(__file__), 'templates/
helloworld.html')
self.response.out.write(template.render(path, template_values))

def main():
application = webapp.WSGIApplication([('/', MainHandler)],
 debug=True)
util.run_wsgi_app(application)

if __name__ == '__main__':
main()



for helloworld.html:



  
My Template
  

  
 {{textMessage}}

[google-appengine] Re: about error django 1.2 was requested, but 0.96.4.None is already in use

[Gillwill]

Another alternative that worked for me, that did not require the
"import django", is by putting the following line:

   os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

right above these lines

   from google.appengine.dist import use_library
   use_library('django', '1.2')

I think it's also important for these lines to be put before any other
import that uses django. For example, if you put them after the "from
google.appengine.ext.webapp import template", it will probably draw
the error because the template import will have already imported the .
96 version.
