I am being asked to come up with a solution that allows a user to set queries on a feature class and related tables from an app or widget and then export the results to an excel sheet. They want the records to be joined so they appear as one line item based on their common ID instead of separate tables. I can come up with the python to join and filter the tables, as well as export the results. The issue is, the users want to run this themselves and aren't familiar with python. My question is, does anyone have a suggestion for the user interface? Is it possible to pass their selections to the python script from an html page?
