Node delete fails

[marcoacierno]

I am using django cms (3.2.5 and Django 1.9.5) with treebeard (4.1.2). Even time I try to delete a CMS plugin it fails with an error 500 and MultipleObjectsReturned: get() returned more than one CMSPlugin -- it returned 36 as error.

The issue happens at MP_NodeQuerySet#delete after finding all the nodes to remove (in my case just one)

# ok, got the minimal list of nodes to remove...
# we must also remove their children
# and update every parent node's numchild attribute
# LOTS OF FUN HERE!
for path, node in removed.items():
    parentpath = node._get_basepath(node.path, node.depth - 1)
    if parentpath:
        if parentpath not in parents:
            parents[parentpath] = node.get_parent(True)
        parent = parents[parentpath]
        if parent and parent.numchild > 0:
            parent.numchild -= 1
            parent.save()
    if node.is_leaf():
        toremove.append(Q(path=node.path))
    else:
        toremove.append(Q(path__startswith=node.path))

at the parents[parentpath] = node.get_parent(True) line. The database seems to returns multiple parents. Might it be caused by the fact that in the database I have multiple cms plugins with the same path? (https://marcoacierno.space/xQzR3Qogo4.png)

(EDIT: I just found that when you delete a root node it also deletes content from other pages because the path starts the same way, (the node.is_leaf() == false if))

If it helps, I also have an issue where, sometimes (at random), when changing/adding/deleting (even if it never works) most content of my website gets mixed up (images/text etc gets moved to the current blogpost)

Any suggestion to how to fix this issue? Or it's a known issue?

Thank you!

Hi, I know it's been years and your png isn't there any more, but it surely was a problem with the queryset. There are a lot of warnings on how to properly subclass querysets. Cheers!
