Odoo record.write() 到 One2Many

Question

Hope you are well today wherever you are:)

I have one function that makes it possible to retrieve a certain fields from other models, which is using self.env[].search . I also successfully rewriting the list of result , but I stumbled upon a confusion where i would like to update that record into other fields using record.write() .

    @api.multi
    def _my_button(self):
        for record in self.env['created.model'].search([]):
            record_a = record.mapped('certain_fields') # saving result from certain_fields inside record_a variable
            record_b = self.number # A number defined by user in current Odoo <form>
            my_new_list = [number * record_b for number in record_a] # rewriting record_a values
            record.write({'destination_field': my_new_list}) #trying to put my_new_list to other fields

It's practically working when i change my_new_list to integer for testing purpose, but i couldn't get it work because dictionary doesn't seems to accept my_new_list .

Is there any way or alternative to write my_new_list within record.write() ?

Answer 1

The value of the destination_field field should be a list of triplet

For example:

(0, 0, values)
adds a new record created from the provided value dict.

Try the following:

my_new_list = [(0, 0, {'final_qty': number * record_b}) for number in record_a]
record.write({'product_lines': my_new_list})

field_name is the field inside the One2Many field used to store number * record_b value
