Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I have a function on_change in a Treeview (editable="bottom"):
Example:
*The problem is when i try to save after on_change, the field [Total] which is a readonly gets cleared/disappear. Just found out that when you set it to readonly=False the value of [Total] remains.
*Is there any method to lock the field rather than setting it to readonly=True? *Or it's still a bug from OpenERP 6.1?
As far as I know readonly fields are not sent to server. You may set an invisible field with the correct value and a related field to display readonly value.
Thanks nbessi, now I know somehow its a bug from 6.1
I also want to know using related field how to use in same table ? Example: fields.related(?, 'total', type='float', relation='current.table', string='Total', store=True),
