selection field

[Cato Nano]

Now that a list of entities represented by my model get correctly shown, I want to add a selection field to my model. Like this

tipo = fields.Selection('tipo', [
('M', 'Male')
('F', 'Female')
],
)

I copied this from the manual, here
http://doc.tryton.org/4.6/trytond/doc/ref/models/fields.html#ref-models-fields

when updating the module like this

:~/tributi$ sudo python3 setup.py develop
:~/tributi$ sudo trytond-admin -c /etc/tryton/trytond.conf -d tryton -u tributi

i get this error

Thanks in advance !

First param is the options, second the label i think ...

You need to separate your tuples with commas in the selection list like this:

    ('M', 'Male),

    ('F', 'Female')

without the comma it looks to the Python interpreter like the second tuple is parameters and the first tuple is a function hence the error.

thank you people

I managed to make it work

I found a selection field in the "sales" module and copied that code and adapted it

Thats how I discovered that the options list ought to be the first argument

For now I have no "form" view for my bolletta so I can t test the drop down menu

But the field shows up in a tree view, so I guess it s ok

Thanks !

ok, now I also have a form view and the selction field works like a charm !!
