I've made 3 models

class Budget(models.Model):

          _name = 'budget.model'

          value = fields.Integer()

          description = fields.Text()

          name = fields.Char()


class Ot(models.model):

          _name = 'ot.model'

            budget = fields.Many2one('budget.model')

            description = fields.One2Many('ot.model.desciption', 'ot_description')


class OtDescription(models.model):

        _name = "ot.model.description"

        ot_description = fields.Many2one('ot.model')

        quantity = fields.Integer()

        value    = fields.Integer()

        description= fields.Text()

    

I would like to show description, value, and quantity = 0 from budget.model inside the description field of ot.model when someone click the budget field of ot.model

I've tryed something inside ot.model

@api.onchange('budget')

def _onchange(self)

    if self.budget:

        self.desciption = self.env['ot.model.description'].search([])

but It's wrong

Dear wildhen,

what is the relation betweet ot.model.description and budget.model. ?

You do one thing, create a budget field in ot.model.description.

Then you can search the description in on-change function.

Hello Wildhen,

This query will return an empty object of the model "ot.model.description".

You need to fetch the data to assign to this field.

You can try this.

def _onchange(self):
    if self.budget:
        objs = self.env["ot.model.description"].search([])
        if objs:
            self.description = [(6, 0, objs.ids)]
I hope this will resolve your query.
