Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I have a list and form views, I can select one element in the list to access the form.
The form has fields A and B (both many2one), when A has one value B must filter by these value.
When I change the value in A, I can use function on_change to set the domain in B.
The problem comes when I access this form view from the list and A already has a value, I don't know how to set the domain then, I have tried with default_get and read functions, but I'm not successful.
I was making it too complicated, I found the solution on https://www.odoo.com/forum/help-1/question/problem-with-a-domain-many2one-22314
It was enough adding the domain to the field, the problem is that I was writing it as:
domain=[('B1.B2', '=', A)]
And it raised an error because A wasn't recognized. I changed to
domain="[('B1.B2', '=', A)]"
Now it works very smooth.
Pau, you need to developed an on_change method on the field which change will trigger the domain change. This page provides an overview of how on_change can be developed.
Thanks John, I don't have any problem with the on_change. If the user changes a field, then there's no problem. The problem is if the user doesn't change the field. The field has content already, but nobody changed the content.
