Using sfPropelActAsNestedSetBehaviorPlugin, if I delete a leaf node I still need to update the tree to make sure there are no gaps left in the left/right values, right?
First of all, I am assuming that I need to update the whole tree (not just the nodes that come after the deleted leaf node) because the deletion of any node anywhere in the tree should reduce the right value of the root node by 2. Assuming this is true. This is the way I expect I have to do it: 1) load the entire tree into an array (using the ScopeId), sorted by left value. 2) iterate over the entire array of tree nodes. Re-attach each node to its parent so that left & right values are updated properly, using the ParentId to insertAsLastChildOf() and reload() the parent after each insertion. Tristan (or any other experienced NestedSet users) could you confirm that (a) a complete tree update is necessary after a node deletion (b) that the method I suggest here is the way to go, or is there a better way? Thanks in advance for any feedback. --peterVG P.S. if this is necessary, would it be possible to add a deleteLeaf() method to the API since there are already a deleteChildren() and deleteDescendants() method? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "symfony users" group.
