Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
Some user opens an edit form on a object, as long as this user doesn´t close this form I want other users to be denied to editing.
Pessimistic locking is not an option with Odoo, being quite impractical in a stateless web-based environment.
Odoo implements Optimistic Concurrency Control:
For every object, there is a virtual
__last_update field that clients can requests explicitly as part of regular
read() calls, on any model. The value is automatically inferred from the
create_date fields that the framework maintains on any record by default. When the client later makes a
write() call on the same record, it can pass an extra context structure containing the original
__last_update value, and the system will automatically raise an error if the record has been updated in the meantime. See the
_check_concurrency() method for more details.
