on_change function in a Treeview

on 2/6/13, 10:18 PM 2,672 views

I have a function on_change in a Treeview (editable="bottom"):


Product Name | Qty.(onchange) | Unit Cost(onchange) | Total (readonly)

Product1 | 3.00 | 512.00 | 1536.00

*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?

You can inherit create and write methods to save the value on Total

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),
