Thank you for the mptt class firstly.
As the documentation of MPTtree says:
* When someone deletes a node which has subnodes, those connections must be re-established to another node.
* It takes many querys to get all descendants or parents for a given node, in Nested Sets it takes only one.
* You have two columns with the same data (id and parent_id).
According to this disadvantages of mptt, I wonder how can I write the implementation of hierarchical(threaded or nested) comment system. As comments may have children comments and children have the parent comment.
Because adding, deleting and editing the comment are available for user, I think mptt would be not a right choice. So any ideas for a situation like mine?
