Create Nuke WriteNode using python

Hi,

I'm trying to create a Shotgun WriteNode with python code, instead of using the shotgun menu in the toolbar.

However, I cant figure out what python code to use.

I know the gizmo itself is called "WriteTank", but when I execute "nuke.createNode('WriteTank')" (like you would do with a normal gizmo) it gives me the error :

"The render path is currently frozen because Toolkit could not determine a valid path! This was due to the following problem: Unable to determine the render template to use!"

When I create a WriteNode using the menu and I check the scripteditor afterwards it gives me this massive code:

import nuke
if hasattr(nuke, "_shotgun_write_node_handler"):
nuke._shotgun_write_node_handler.on_node_created_gizmo_callback()
import nuke
if hasattr(nuke, "_shotgun_write_node_handler"):
nuke._shotgun_write_node_handler.on_knob_changed_gizmo_callback()
import nuke
if hasattr(nuke, "_shotgun_write_node_handler"):
nuke._shotgun_write_node_handler.on_knob_changed_gizmo_callback()

    This was answered via support, but just to make sure that the answer is available for everybody, here is the code snippet that can be used to create a writenode directly from python:

    import sgtk
engine = sgtk.platform.current_engine()
app = engine.apps["tk-nuke-writenode"]
app_module = app.import_module("tk_nuke_writenode")
handler = app_module.TankWriteNodeHandler(app)
node = handler.create_new_node("Shotgun Quick Dailies")

    You need to update the profile name with the correct profile for the type of node that you want.
