How to filter Python Toolbox parameter for Tables

JohnDye — Sat, 11 Dec 2021 21:50:45 GMT

Trying to set a filter on a Python toolbox parameter to only allow tables to be input.

Currently doing this:

        param0 = arcpy.Parameter(
            displayName="Table",
            name="in_Table",
            datatype="GPTableView",
            parameterType="Required",
            direction="Input")
        param0.filter.list = ["Table"]‍‍‍‍‍‍‍

However, the filter doesn't seem to work.

the parameter list looks like the correct form (ie a list of entries)

which begs the question, about 'Table' being the appropriate entry

I don't believe filters are valid on GPTableView parameters. Your best bet might be to use Describe in the UpdateMessages method to check whether it's actually a table or table view, then raise an error if it isn't.

Thanks guys. I figured this was probably something that was implemented but wanted to check with the SMEs to make sure I wasn't missing something. Boo, Esri. Fix it. https://community.esri.com/ideas/14090
