Hi all, I have been recently learning python but cant seem to figure out why this code wont work, i found this code for adding the “HasParameter” Filter onto my schedules which works if you feed the script a direct view but if its a list of views, it throws this error

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):
File “”, line 22, in
AttributeError: ‘List[object]’ object has no attribute ‘ViewType’

Thank you for any help, and a explaination would also be helpful! :smiley:

Code Below:

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument

def fieldId(schDefinition, fieldName):
	OrderedFields = schDefinition.GetFieldOrder()
	for x,id in enumerate(OrderedFields):
		field = schDefinition.GetField(id)
		if field.GetName() == fieldName:
			return schDefinition.GetFieldId(x)
	return None       

schedule = UnwrapElement(IN[0])

OUT = []

if schedule.ViewType == ViewType.Schedule:
	try:
		definition = schedule.Definition
		field = fieldId(definition,IN[1])		
		TransactionManager.Instance.EnsureInTransaction(doc)		
		filter = ScheduleFilter(field, ScheduleFilterType.HasParameter)
		definition.AddFilter(filter)		
		TransactionManager.Instance.TransactionTaskDone()		
		OUT.append(schedule)
	except:
		OUT.append("Check Field Name")
else:
	OUT.append("Input View is not a Schedule")

@Bladen when dealing with more than one item, in your case a list of items, you need a for loop to make it work, check in the forum for it, there are plenty of examples
