one2many Beziehungen sind genial, vor allem wenn folgendes bekannt ist:
(0, 0, { values })
link to a new record that needs to be created with the given values dictionary
(1, ID, { values })
update the linked record with id = ID (write *values* on it)
(2, ID)
remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID)
cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID)
link to existing record with id = ID (adds a relationship)
(5)
unlink all (like using (3,ID) for all linked records)
(6, 0, [IDs])
replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)
Beispiele:
'tax_ids': [(6, 0, tax_ids)]
'sale_line_ids': [(4, self.id)]
