Python module - create/delete nodes inside locked asset

[papsphilip]

how can i delete/create nodes in a locked hda from the python module?

i am using a button with a callback script that runs a delete() function

for n in node.children(): n.destroy(True)

i get an error message that i don't have permissions because the asset is locked. Is there a way around this?

you will need to unlock it first. https://www.sidefx.com/docs/houdini/hom/hou/Node.html#allowEditingOfContents

If it is your own hda you can also predefine it as editable using the node tab in the type properties.

what do you mean predefine it as editable? in the node tab there is the "Editable Nodes" field, but that concerns a specific nodes inside the hda.

i wanted a locked asset i can pass around to other creators where they would press a button and create a bunch of nodes, press another and delete them. without having access to the network inside.

This editable option is inherited to all children. So create a subnet in the hda and do the procedural creation inside the subnet.
