Odoo use id of just created record - odoo

Question

I need to create company and right away create contact that bound to that company:
vals = {...}
company = self.env['res.partner'].create(vals)
vals = {'company_id': company.id, ...}
contact = self.env['res.partner'].create(vals)
But odoo says: DETAIL: Key (company_id)=(49) is not present in table "res_company".
Transaction is not commited yet (as i suppose).
So how can i use field of just created records?

<record model="ir.cron" id="ir_cron_load_data">

Answer 1

vals = {...}
company = self.env['res.partner'].create(vals)
vals = {'company_id': company.id, ...}
contact = self.env['res.partner'].create(vals)
The company_id field is a relational field between the res_partner and res_company tables. You try to create a record on the res_partner using the vals, the vals has a company_id key that has a company.id as its value. The company.id that you have there is the id of the new record you created on the res.partner table.
You have to create the company in the res.company table:
company = self.env['res.company'].create(some_vals)
and then get the id of that company company.id
