I understand what you are asking. Something like the ability of web2py to
define stuff in a models file and it would be available to the views.
Problem with that design is the overhead. With py4web we are trying to be
more efficient.
There are many ways to do this:
1) create a function that returns the info you need and pass this function
to the layout. For example:
def get_info(auth):
return {... whatever you need ...}
@action('index')
@action.uses(auth)
def index():
return dict(info=get_info(auth))
2) create a new fixture that injects data in the template
from py4web.core import Fixture
class InfoInjector(Fixture)
def transform(self, output):
if isinstance(output, dict) and 'info' not in output:
output['info'] = get_info(auth)
return output
@action('index')
@action.uses(auth, InfoInjector())
def index():
return dict() # info is automatically injected
3) add logic directly to the template as in:
[[from app.thisapp.common import get_info, auth]][[info =
get_info(auth)]] ... [[=info]]
I like solution 2 best
