Purpose
=======
During the development of the task #2169100, it appeared that the synchronisation
of a task's partner_id according to its project's partner_id and its parent's
partner_id was not very clear.
A first idea was to simplify the partner_id management: as it could be annoying
for the customer to see all the task's partner_id overriden after project's
partner_id modification, the idea was to just use the parent's parnter_id or the
project's partner_id as default value of the task's partner_id. Then, if the
partner_id of the project or of the parent is changed, there is no more impact
on the task partner_id itself.
The main problem of this solution is that the management of the task's partner_id
is also extended in several others modules like sale_project and sale_timesheet.
You can find below what seems to happen with all these task partners.
Start following rules according to which module is installed.
(for the record: sale_timesheet depends on sale_project which depends on project).
Rules are applied in the order they are written.
Rules labelled "O" only apply when changing the project through the task form view.
Rules labelled "C" apply everywhere.
technical: C=compute, O=onchange
project
C.1 If parent's partner changes and the partner is not set, then set the parent's
partner
C.2 Else if project's partner changes ant the partner is not set, then set the
project's partner
sale_project [+ project]
C.1 If the project's sale order line's partner changes and the partner is not set,
then set the project's sale order line's partner
C.2 Else apply (project.C) rules
sale_timesheet + [sale_project + project]
C.1 Apply (sale_project.C) rules
O.1 If the project is billed "At Project rate" or "At Employee Rate" and the
partner is not set, then set the project's sale order's partner
the sale order line's partner
Specification
=============
- If the partner changes, we ignore all current tasks and let them be. We set the
new partner as default value on all new tasks. In detail, we have done
this:
- When the user creates a task give the customer of the default project or the
task parent as default customer for the task.
- When the user changes the project and no partner in the task, we take the
partner of the new project (if this project has a customer).
- When the user changes the customer of the project, the linked tasks are not
impacted by this changes, even if some tasks have not a customer yet.
- When the user changes the customerf of the parent task, the child tasks are
not impacted by this changes, event if these tasks have not a customer yet.
- remove the onchange rule to remain consistent.
