One2many or Many2many

 Agregar [(4,] 


For Many2many For a many2many field, a list of tuples is expected. Here is the list of tuple that are accepted, with the corresponding semantics (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) Example: [(6, 0, [8, 5, 6, 4])] sets the many2many to ids [8, 5, 6, 4] And One2many : (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) Example: [(0, 0, {‘field_name’:field_value_record1, …}), (0, 0, {‘field_name’:field_value_record2, …})]

CASCADE: Delete the Course record with matching student_id when Student is deleted

RESTRICT: Cannot delete the Student as long as it is related to a Course.

NO ACTION: similar, but is a deferred check: You can delete the Student but you have to make sure that the integrity is OK when the transaction is committed.

SET DEFAULT: uses openerp default definition (see _defaults dict in the python model definition)

SET NULL: when a Student gets deleted, the student_id becomes NULL in the DB.
