[ahmadproper]

I want to ask how to insert/create master detail on odoo model with larado library, for example
i want to insert stock.picking as header and stock.move as detail at once.
fyi, i try to insert once by once and it succesfully,
first i create / insert data stock.picking after i got picking_id, i insert ht stock.move.line model.

now how to create / insert both of models relation at once...
