Event_sender 'Application' object has no attribute 'GetElement'

Revit API
1

Trying to make a hook that looks at the current view’s filters to see if it is a site plan and check a parameter automatically. First thing I’m running into is that the event_sender doesn’t seem to have GetElement.

I saw this used here: Using Hooks to get the Family Name being loaded - #2 by sanzoghenzo

I know this is supper messy. I plan to clean it up later:

# Checks if placed element is in a view that has a NeedsSite filter and checks that parameter automatically.

# Import libraries
from pyrevit import DB, revit, script, forms, EXEC_PARAMS

from Autodesk.Revit.DB.Events import DocumentChangedEventArgs
from Autodesk.Revit.DB import ElementFilter, ElementId, BuiltInCategory, ElementMulticategoryFilter

# import clr
#
# clr.AddReference('System')
# from System.Collection.Generic import List

from System.Collections.Generic import List

# NOTE TO CODY : This section may not work in hooks at all. Try using sender.GetElement(Id) instead of using doc.
# https://discourse.pyrevitlabs.io/t/using-hooks-to-get-the-family-name-being-loaded/1938/2
# doc = __revit__.ActiveUIDocument.Document
# cView = doc.ActiveView
# NOTE TO CODY

else:

When you don’t know what methods and props an object has try print(dir(object))

I wrote a little function to help understand objects. Might be useful here…

def print_attributes(object, include_dunders=False, include_callables=False):
    # BUG: failes if any getattr fails
    if include_dunders:
        if include_callables:
            return '\n'.join('{}={}'.format(x, getattr(object, x)) for x in dir(object) if hasattr(object, x))
        else:
            return '\n'.join('{}={}'.format(x, getattr(object, x)) for x in dir(object) if hasattr(object, x) and not callable(getattr(object, x)))
    else:
        if include_callables:
            return '\n'.join('{}={}'.format(x, getattr(object, x)) for x in dir(object) if '__' not in x and hasattr(object, x))
        else:
            return '\n'.join('{}={}'.format(x, getattr(object, x)) for x in dir(object) if '__' not in x and hasattr(object, x) and not callable(getattr(object, x)))

I use RevitPythonShell to explore this kind of thing, but probably rpw.forms.Console() could do the same thing in a pyRevit script. I also highly recommend RevitDBExplorer.
