EmType hierarchy is handled by 3 functions :
- EmType.superiors()
- EmType.subordinates()
- EmType.add_superior(em_type, nature)
- EmType.del_superior(em_type, nature)
Hierarchy implementation is not tested (because their is no tests...)
Added a function to get authorized relation nature from an EmClassType
Added the nature of a relation to the primary key of em_type_hierarchy table (triple pk : sup_id, sub_id, nature)
The dates are set in EmComponent::create() for date_create and in EmComponent::save() for date_update
The values are sets to datetime.datetime.utcnow() so we now that EVERY date in the db are in UTC, no matter django, database or even server configurations.
We will have to take care to convert dates from database to django timezone in dates fieldtypes.
