Feature Set parameter in a tool destined to be a gp service

KevinGooss — Thu, 25 Oct 2012 20:36:14 GMT

I'm converting some 10.0 python code into a 10.1 python toolbox.
One of my parameters is a Feature Set.
in my 10.0 code if i run this in arcmap i get the interactive buttons to digitize a shape
in 10.1 i don't get this option. i just get the layers in the map or a folder icon to load other layers.

I think this has something to do with the schema. this is an input parameter.
in 10.0 world i would have used catalog to point this tool at a dummy schema just to get it stubbed out.

At 10.1 i think it is supposed to work differently but i can't figure it out and i don't see enough in the docs to help me.
there is alot of stuff in the docs about schema for output fs params, mine is input.
i want to serve this script as a gp tool in ags. the app would upload features in a format that the fs param can understand.

i saw something in the doc about needing geometryType and fieldRule params but i could use a working code sample.
here is what i have thus far (this is in a python toolbox):

class TestTool(object):
    def __init__(self):
        self.label = "TestTool"
        self.description = "TestTool"
        self.canRunInBackground = False

    def getParameterInfo(self):
        #Feature Set you pick a layer or load a layer
        param0 = arcpy.Parameter(
        displayName="aFeatureSet",
        name="aFeatureSet",
        datatype="Feature Set",
        parameterType="Required",
        direction="Input")
        #param0.value = ""

        param1 = arcpy.Parameter(
        displayName="aString",
        name="aString",
        datatype="String",
        parameterType="Required",
        direction="Input")
        param1.value = ""


        params = [param0, param1]
        return params

    def isLicensed(self):
        return True

    def updateParameters(self, parameters):
        return

    def updateMessages(self, parameters):
        return

    def execute(self, parameters, messages):
        #do stuff

Almost there....just need to assign the template to the value.

    #Feature Set you pick a layer or load a layer
        param0 = arcpy.Parameter(
        displayName="aFeatureSet",
        name="aFeatureSet",
        datatype="Feature Set",
        parameterType="Required",
        direction="Input")
        param0.value = "c:\\mytemplates\\line.shp"
        #or
        #param0.value =  os.path.join(os.path.dirname(__file__), "f.gdb\\line")

I just noticed that in the docs after i posted. I used a lyr file and now in arcmap i do see the new feature template so i am able to digitize in arcmap, so that's cool.
but when i publish the tool and send it a feature via the rest interface i get an error:

Unable to complete operation.
The workspace is not connected.

I really don't need any of the schema i'm simply sending in coordinate sets for a polygon. I'm using that in the tool to do an intersection and then return a specific string out of the tool. Is the feature set overkill for what i need?

I'm publishing from my ags web manager machine over to my ArcServer machine by creating a disconnected sd file. Maybe something isn't being copied during the publish process properly?

Well a featureset takes a certain input. So I'd use whatever you have your coordinates in. If thats something which featureset can read, then go with that. If its a "string", like [[2,2], [5,5]] then use the string control.

I sort of understand what you're doing, but without the complete picture I can't offer a "best suggestion". My guess though is you probably have formatted json that you're passing in so you should be using the featureset control?

yeah, its json that the js api creates when a user digitizes within my app.
now that the rest endpoint has the schema (via the value in python) it fills in all of that for me when i go to the execute method.
it leaves the features as a [] so that i can drop my geometry representation in there.
I don't put in any attributes because this is just a sketch the user makes and the script is to validate that the geometry is acceptable before dumping it in.
I suppose i could trim my schema down to have the bare attributes rather than those of the target feature class that the feature is destined for.
I'll give that a try and see how it shakes out. I'm not interested in attributes for this gp tool, just want the geometry.
