nicer appengine generates

>>> File: templates/functions.py:
import logging

from google.appengine.api import users

from tipfy import RequestHandler, request, response, redirect
from tipfy.ext.user import create_login_url, create_logout_url, create_signup_url, get_current_user

from tipfy.ext.blobstore import BlobstoreUploadMixin, BlobstoreDownloadMixin

class BaseRequestHandler(RequestHandler):
  def generate(self, path, template_values={}):
    from tipfy.ext.mako import render_response
    context = {
      'current_url': request.url,
      'login_url': create_login_url(request.url),
      'logout_url': create_logout_url(request.url),
      'signup_url': create_signup_url(request.url),
      'user': get_current_user()
    }
    context.update(template_values)
    return render_response(path, **context)
  def redirect(self, url, code):
    return redirect(url, code)

>>> Usage from a handler:
from templates.functions import BaseRequestHandler
from tipfy import request, response, redirect

class HomeHandler(BaseRequestHandler):
  def get(self, **kwargs):
    return self.generate(path='root/home.html', template_values={'message': 'Welcome!'})
