I'm wondering if anyone knows a fairly simple way to implement the
following in Trac 0.12. Our software development plan requires that
*only* Ticket Review Board members have the ability to assign tickets
to a milestone. There are two groups, trb and developers. The
developers need to be able to see which ticket a milestone is assigned
to, but shouldn't be able to change the milestone that a ticket is
assigned to. Developers also need to be able to view milestones and
currently have the MILESTONE_VIEW permission.
With the MILESTONE_VIEW permission, a user can assign tickets to a
milestone (1). So I need to revoke the ability for users with
MILESTONE_VIEW to assign tickets to a milestone, and add a permission
for assigning tickets to a milestone (e.g. TICKET_CHGMILESTONE).
Actually, the latter is probably not necessary since members of trb
have MILESTONE_CREATE and MILETONE_MODIFY permission.
So, basically it looks like I just need to figure out how to revoke
"assign tickets to a milestone" for users with MILESTONE_VIEW
permission, but retain the ability to review the milestone.
