# When included, it adds the ability to rebuild nested sets, thus fixing
|
|
# corrupted trees.
|
|
#
|
|
# AwesomeNestedSet has this functionality as well but it fixes the sets with
|
|
# running the callbacks defined in the model. This has two drawbacks:
|
|
#
|
|
# * It is prone to fail when a validation fails that has nothing to do with
|
|
# nested sets.
|
|
# * It is slow.
|
|
#
|
|
# The methods included are purely sql based. The code in here is partly copied
|
|
# over from awesome_nested_set's non sql methods.
