In case you don't know, you can also put functions inside model, so
that they are globally available. I think this make your controller
and view have less coupling.
in your model:
def helperFunction(a):
return a*a
in your controller:
def index():
return {}
# much cleaner than return dict(func1=helperFunction,
func2=someOtherFunc, ...)
in your view:
{{=helperFunction(5)}}
