I'm trying to create a product and its variant. Afterwards I want to add some quantity to stock (including price_unit), but it doesn't work like that. Seems like "env['stock.move'].create" doesn't take any effect.

What am I doing wrong?

Thanks!

Code example:

product_template = self.env["product.template"].create({'name': title,
    "default_code": permalink,
    "price": price,
    "type": "product",
    "weight": weight})

product_template.write({
    'attribute_line_ids': [(0, 0, {
        'attribute_id': 2,
        'value_ids': [(6, 0, [156])],
    })]
})

product_product = product_template.product_variant_id
product_product.write({
     'name': title,
     "default_code": sku,
     "price": price,
     "type": "product",
     "weight": weight
})
move = self.env['stock.move'].create({
    'name': 'test_move',
    'product_id': product_product.id,
    'product_uom': 1,
    'product_uom_qty': quantity,
    'price_unit': cost_price,
    'location_id': 14,
    'location_dest_id': 8,
})

move._action_confirm()
move._action_assign()
move.move_line_ids.write({'qty_done': quantity, 'product_uom_qty': 0})
move._action_done()
