Python Toolbox as Geoprocessing Service in Web App?

WilsonIonara

Is it possible to publish a geoprocessing service generated from a python toolbox? This will be used in a web app, so is it possible that all the custom messages that were created in the python toolbox will appear in the web app when the geoprocessing service is used (the user will click a button to run the geoprocessing service)? Or do I have to write special code in javascript to create alerts that will be created from results of the geoprocessing service? The python toolbox works wonders in ArcMap so I am trying to figure out how to create a web app with a geoprocessing service resulting from that.

Thank you!

I usually script my stuff into a python.py file.
Then I add my python script to a toolbox.
And finally I publish the gp result as a geoprocessing service as shown on the tutorial I recommended above.

After a quick look at python toolboxes, it seems to me that it is almost the same thing except that my two first steps are merged in one.

Then to publish it a geoprocessing service, it works the same way.

You can define inputs but you don't have to if you don't need any inputs from the webapp.

input = arcpy.GetParameterAsText(0) #It should be working the same in a python toolbox or it should be something similar

You can define an output too if you want (that could be the "message" you are talking about) :

if the script works :
       output = "job done"
else :
       output = "job not completed"

arcpy.SetParameterAsText(1, output)

- > in GetParameterAsText(0) and SetParameterAsText(1), 0 and 1 refer to the row number of the parameters list.

What I don't know is how to define the inputs, output data-type (String, File), direction (Input, Output) and type (Optional, Derived) from a python toolbox (parameters don't appear in the toolbox properties). It might be filling out automatically with python toolbox.

Then,  when you call your geoprocessing service from you webapp, it will return an output if you defined one.
