i have 2 fields, one we will pick a date, i would like the other to automatically compute -5 weeks from the selected date. i have played with the compute field in studio but have had no luck getting anything to work.

so far i have:


for record in self:

  record[("x_studio_field_CgBpj")] = record.x_studio_field_47ZJc - datetime.timedelta(weeks=+5)

Odoo 11, Python 3.5

from datetime import datetime, timedelta
from odoo.tools.misc import DEFAULT_SERVER_DATETIME_FORMAT

class Test(models.Model):
    _name = "dhac.rad.project"

    test1 = fields.Datetime(string="Date Time A")
    test2 = fields.Datetime(string="Date Time B", compute="dp_test1")

    @api.depends('test1')
    def dp_test1(self):
        if self.test1:
            raw = datetime.strptime(self.test1, DEFAULT_SERVER_DATETIME_FORMAT)  - timedelta(weeks=5)
            self.test2 = str(raw)

from datetime import datetime, timedelta

from odoo.tools.misc import DEFAULT_SERVER_DATETIME_FORMAT

for record in self:

record[("x_studio_field_CgBpj")] = datetime.strptime(record.x_studio_field_47ZJc, DEFAULT_SERVER_DATETIME_FORMAT) - timedelta(weeks=5)

Try it bro, i don't test it

[tab]record[("x_studio_field_CgBpj")] = datetime.strptime(record.x_studio_field_47ZJc, DEFAULT_SERVER_DATETIME_FORMAT) - timedelta(weeks=5)

raise ValueError("forbidden opcode(s) in %r: %s" % (expr, ', '.join(opname[x] for x in codes)))

Are both fields of the same type? (Datetime or Date). If not, you need to convert it. I tried something similar and this was the problem I had.
