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

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?

Tác giả

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.

Tác giả

Thanks. I hope there will be a solution.
