|
|
|
|
Need action feature can be used by models that have to be able to
|
|
signal that an action is required on a particular record. If in
|
|
the business logic an action must be performed by somebody, for
|
|
instance validation by a manager, this mechanism allows to set a
|
|
list of users asked to perform an action.
|
|
|
|
Models using the 'need_action' feature should override the
|
|
``_needaction_domain_get`` method. This method returns a
|
|
domain to filter records requiring an action for a specific user.
|
|
|
|
This class also offers several global services:
|
|
- ``_needaction_count``: returns the number of actions uid has to perform
