Invoice lines and sale order lines relation

Question

Hi,
probably a novice question but here it is.
I need to create a relation on each invoice line to its corresponding sale order line creating a new field on the invoice line form. (Just the same way that delivery out lines are related to sale orders lines). Is it possible to do this easily?.
Thanks in advance.
Regards.

hello,

You already have this:

Look on the *sale.order.line* model.

invoice_lines : list of invoice lines linked to this sale.order.line
invoiced : if this sale.order.line has been invoiced
You need the reversed one from *account.invoice.line* ? Add this to your account.invoice.line model (not tested but should works):

'sale_order_lines': fields.many2many('sale.order.line', 'sale_order_line_invoice_rel', 'invoice_id', 'order_line_id', 'Sale Order Lines', readonly=True)

Hi Nicolas,
thank you very much for your kind response but this is not exactly what i needed.
I meant one to one relation for each object (invoice_line_id --> sale_order_line_id).
Regards.
EDITED:
This is what i did (works for me but it's not very neat):
On account_invoice.py (account)
Add column in account_invoice_line:
'sale_order_line_id': fields.many2one('sale.order.line', 'Sales Order Line', help='Sale Order Line'),
On sale.py (sale)
Add column on _prepare_order_line_invoice_line function:
