main entity and lines

[Cato Nano]

Some time ago I asked how to have on my Bolletta lines fields defined on the main entity, the Bolletta

I did this with some date fields and it worked like a charm.

Now I need to read the value of a selection field, defined on Bolletta

In fact, I have to assign the "invisible" state to a field on the base of a selection on a selection field on Bolletta

It doesn' t work

How do I read the content of a selection field from a line ?

Thanks

What does not work? Could you provide more information please?

If you are going to evaluate it on pyson, you should create a functional
field. Here is an example:

I made this field. the thing runs, but the field doesn't appear
https://gitlab.com/humanitiesNerd/tributi/blob/master/affissione.py#L97

I' d like to be able to debug this not appearance myself

How would you do, if you were in my shoes ?
Would you use Proteus on a SQLite db for debugging this ?

The problem is that self.bolletta.tipo is not a field of the model. You
can not use the dot notation to navigate on pyson statements, so you
should create a functional field that returns the value of the
referenced field.

Ah, I will try this.
Thanks !

I tried

Not only the field had to belong to the model but also I had to move from this

states={'invisible': Eval('bollettaTipo') != 'commerciale'}

to this

states={'invisible': (Eval('bollettaTipo') != 'commerciale')}

in order for it to work :-)
