How to recompute stored functional field values in Odoo?

问题

Sometimes stored fields must be recomputed, but triggers can not be launched (e.g. in case of SQL injection).

How to recompute them an easy way?

回答1:

(Because I came here via google:)

You can also do this from the Odoo Shell:

# python odoo.py shell -c openerp-server.conf  -d <database>

>>> model = env['account.invoice']
>>> env.add_todo(model._fields['amount_total'], model.search([]))
>>> model.recompute()
>>> env.cr.commit()

Odoo shell is available in 9, 10 and via an OCA module in 8.

回答2:

In v8.0 (should work in 9.0 too) you can do it like that:

# Recompute amount_total for account.invoice

env.add_todo(model._fields['amount_total'], object)
model.recompute()

# where
# object - recordset of instances to recompute field for
# model - recordset instances model

Above code can be used in server action directly.

回答3:

in the odoo11

env.add_todo(model._fields['loading_time'], env['product.product'].search([]))
model.recompute()
