Adding a principal to 2 projects with member inheritance leads to an error
|Assignee:||Jean-Philippe Lang||% Done:|
When batch adding a user or a group to a project through the projects tab of the user/group page, adding the a user or group to 2 projects where one project inherits its members from the other might lead to an error (depending on the order of the projects, the parent project must come before the child project for this to happen, which it should as in the batch add view projects are arranged in trees). If more than those 2 projects are involved in the batch addition to a project, the user or group won't be added to all projects that come after the child project as the processing stops on the error.
This happens in source:/trunk/app/models/member.rb@16379#L175: First all
Member s are created, then they are saved in the
principal.members << members line. Saving the
Member object for a parent project with a child project inheriting its members will create a
Member object for the child project too, which then leads to an error when the
Member error created for that child project is saved and recognised as a duplicate.
Adding a principal to 2 projects with member inheritance leads to an error (#25289).

The attached patch solves this problem. No test though as this method is currently untested, we can provide tests too if required.
The patch saves each new
Member directly in the loop instead of saving all in one go at the end of the loop. Please note that this does not significantly affect performance as
principal.members << members still saves each
Member one at a time. This allows the loop to recognise if a previous iteration already created a
Member we are trying to instantiate and avoids the clash described above.
Please note that roles are added to the
Member instead of destructively replacing already present roles. This would also allow changing the "Add project" modal of groups/users from being able to only add the group/user to projects it is not already a member of to adding the user/group with the selected role to any project in addition to already existing role/project combinations for that user/group.
