The issue is that some time ago I did a odoo test, in which I was asked to have a field in a table
I know that with sql it would be something like that
_sql_constraints = [('def_identification_unique', 'unique(blablabla)',
'blablabla must be unique!')]
I would like to know how to make the field unique but using a python function.
Thanks
To make a single field, we add the constraint in the definition of the model with Python, when we are going to create the table or when we create the field (we could not add it to a field with previous data.
_sql_constraints = [
('nombre_constraint', 'unique(nombre_campo)', "Mensaje a mostra en caso de violación"),
]
