Computed field to get the row number

Question

Hello!
I have a table like this:
row_number some_data_1 some_data_2
1

2

And I want the row_number to be automatically set to values ​​starting from 1

How can I do it?
What code can I write in "Advanced Properties - Compute" on the row_number field?

I tried to do like this:
increment = 1
for record in self:
record['row_number'] = increment
increment = increment + 1 But when trying to add new lines - new lines start at 1 again

Help, please!

Using Odoo Sequence you can implement your idea
firs create the sequence using xml code
then in py file call you sequence like following cod:
@api.model
def create(self, vals):
vals['row_number'] = self.env['model.model'].next_by_code('cod.cod')
return super(ClassName, self).create(vals)

Hi!
Why don't you just retrieve the id of the record :)? When a new record is created, Odoo will automatically give it as an ID the next number in the list (so that it's always unique). You can retrieve it with record.id.
You may also have a look at the Getting Started tutorial in Odoo Docs if you haven't already ;) : https://www.odoo.com/documentation/15.0/developer/howtos/rdtraining/04_basicmodel.html [1]
Hope this helps!
Best,
Fabio
