Hello Daniela,

You can write as following :

@api.multi
def create_contact_tag(self):
	order_lines = self.env['sale.order.line'].browse(self._context.get('active_ids', []))
	for line in order_lines:
		vals = {}
		if self.name_market :
			vals.update({'market_tag_ids':[(4,self.name_market.id)]})
		if self.name_application : 
			vals.update({'application_tag_ids':[(4,self.name_application.id)]})
		if vals : 
			line.order_partner_id.write(vals)

Thanks,

In the first step I want to create one rcord for each order_partner_id. For example I selected five sale_order_lines and these belong to three orders to three different customers then I want to create three records with the selected tag id's (either market tag and/or application tag) and the partner_id's.

In the next step I want to create records in my relation tables (partner_tags_market_tag_rel and partner_tags_application_tag_rel). But this is the second step. I would be really glad when I can manage the first step and konw how to manage the second step (as far as I understand I have to create records by sql injection because relation tables are not in the ORM model).
