I have an on_change method that assigns a list of tuples to a Selection field


But I get the error message in the subject

Why is that ?

The tuples are like (int, string)


I tried casting the 2 elements in the tuples to 2 strings, int for the id and string for the value, string for the id and int for the value...


I just want to create a list of choices for a dropdown menu field that depends on the value in another field


How am I supposed to do that ?

Hi Adriano,

Try this code 

@api.onchange('selection_field')
def _onchange_domain(self):
    if self.selection_field == 'value':
        domain = [('id', '=', self.id)]
    else:
        domain = []
    return {'domain': {'another_field': domain}}

Also, Check this reference to apply dynamic domain for relational fields 

Dynamic domain
