Geoprocessing Service from Python Toolbox to create a web map?

ionarawilson1 — Fri, 30 Aug 2013 14:47:42 GMT

Hi guys, I have created a python toolbox for 8 tools. One of the tools calculates a plan id based on the county where the polygon is drawn and the year from a date entered by the user.

I would like to create a web app with all these tools. My web app already has editing capabilities and the feature service created for these tools can be already be edited in the web app.

But I need to calculate that PlanID field (the field is already in the database), so I am guessing I need to convert my toolbox script to a geoprocessing service.

If so, how can I do that, since I already have the editor part working in the web app, so I don't need that part of the script to enter the data, just the part that after getting the data, it calculates the planid based on the county where the polygon created is. Here is the python tool script ( I deleted some parts like some of the parameters and messages so it would fit here)
What would I need to change in my code for it to work? Can you please take a look at the python code and give me some advice on what to do? Any idea, or general idea on where to go from here would be awesome! The javascript code is in the following post.
Thank you!!!
