Re: Fellows .. does “django-mptt” fit this Course Structure system?
Nicolas CANIART
Regarding the theiry, what you are describing is not teresa but a DAG (Directed Acyclic Graph) which is not a teresa anymore.
Yet lots of CES built on top of mort solve this problem that way (tanks django-mptt ability to deal with a forest not just a single tree):
- they would put the shared node(s), the tests in your case, in seperate trees.
- where the shared node would be in the tree, add some kind of virtual node which is only here to point to another tree.
This very much like a symbolic link on a file system.
Home this help. Regards, Nicolas.
