Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
class A(models.Model):
b_ids = fields.One2many('a', a_id);
@api.onchange('b_ids')
def set_all_other_value_to_false(self):
for b_id in self:
b_id.boolean_flag = False
#how can I set all other value to false, except the last one which I selected to True?
class B(models.Model):
boolean_flag = fields.Boolean(default=False)
a_id = fields.Many2One('a')
I don't know how I can set all boolean_flag to False except the last one which I selected. How can I solve that problem?
"self.b_ids.ids" to get list
use sql to select this list
compare "boolean_flag" in db and in self.b_ids.boolean_flag
Try:
update value via self.env

Or
Override write method
it does not work with sql, because it can be that it is not saved in the database (create modus).
In onchange Odoo creates a new object and replaces self with it. The origin object can be found under self._origin
Check if this is useful?
how does this solve this problem? can you give a example?
the view should be updated immediately.
Does the b_ids.ids change? Only change b_ids.boolean_flag? Do you want to check the last click?
yes, I want to know to last click. and I want to set the last boolean_flag to True and the rest records of False.
This is impossible in the general case, when all records b_ids are not stored in database. Only solutions is to modify javascript.
Thanks. I hope there will be a solution.
