not callable

[Cato Nano]

I am creating some new calculated fields, running tests along the way

The last one of such fields is giving me troubles

This is the result of running the tests

why is it not callable ?

It's no different than many other methods and they are all callable

It' s here

Thanks in advance

even from within Proteus I can' t find the attribute.

I don't understand, it's no different than at least other 3 fields;

Those work. This one doesn't

For now I gave up in making it depend on another calculated field and I' m doing the same calculations again

But the fact that I don' t understand the issue makes me uncomfortable

[Cato Nano]

I found the problem

Here is an example
https://gitlab.com/humanitiesNerd/tributi/blob/master/affissione.py#L176

if you don' t mind click on the link, here's the code

if self.formato:
if int(self.formato) >= 16:
somma = somma * 2
if 8 <= int(self.formato) <= 12:
somma = somma * 1.5

In this example, the introductory

if self.formato:
...

is necessary

in fact, WITHOUT that introductory if, like this

if int(self.formato) >= 16:
somma = somma * 2
if 8 <= int(self.formato) <= 12:
somma = somma * 1.5

self. formato would turn out to be NoneType


This discovery allowed me to continue and finish this stage of the project

Admittedly I had to do some research about python decorators, in order to understand this

Probably more research will be necessary, anyway

I know I bothered you, I apologize
