Get current scope in scripting

[hunterdg]

@paul-griffith

PageModel is the class. The PAGE attribute will always be present because it's a ThreadLocal field:

So if pageModel.PAGE.get() is not None: would be the equivalent operation and should work.

asynchronous thread

The asynchronous thread will not have the thread local for the page.

i think that results in if pageModel and pageModel.PAGE.get() is None if i remember correctly (notice the absence of not)

edit for clarity:

from com.inductiveautomation.ignition.common.model import ApplicationScope

def isPerspectiveAsync():

	# https://forum.inductiveautomation.com/t/get-current-scope-in-scripting/55686/11
	try:
		from com.inductiveautomation.ignition.gateway import IgnitionGateway
		pageModel = IgnitionGateway.get().moduleManager.resolveClass("com.inductiveautomation.perspective.gateway.model.PageModel")
		return ApplicationScope.isGateway(scope) and hasattr(system,'perspective') and pageModel.PAGE.get() is None
	except: return False
