I\'m trying to pass some variables from the child page to the template. This is my python code:
if self.request.url.find(\"&try\") == 1:
isTr
I do not understand your problem. When you pass variables to the context (as you do with trying) these variables will be available in the child and the parent. To pass title to the parent, you have to use inheritance, sometimes in combination with super : http://jinja.pocoo.org/docs/templates/#super-blocks
