no_cycle checks that the graph is acyclic like you say, preventing a single link type forming a loop e.g. A depends on B depends on C depends on A. parent_child in addition checks that a single link type forms a tree - namely that a ticket may have many children, but at most one parent. -- Alex Willmer <[email protected]> http://moreati.org.uk/blog http://twitter.com/moreati -- You received this message because you are subscribed to the Google Groups "Trac Development" group.
