WorkflowExecutionError

概要

The WorkflowExecutionError exception is raised when a workflow encounters an execution error.

ディスカッション

The WorkflowExecutionError exception is raised if the workflow cannot be executed. For example, if the job is not assigned to the current user or the job is closed, it is not possible to execute a job's workflow.

コードのサンプル

The WorkflowExecutionError exception is used below to handle any errors that result from trying to execute the workflow.

import arcpy, sys, traceback

#Define the callback response function. In this case it will prompt the user using the console to respond.
def callback(question, responses):

    # Print out the expected responses
    for resp in responses:
        print("[%i] %s" % (resp[1], resp[0]))
		
    # Prompt the user to respond
    val = int(input("%s - %s: " % (question[1], question[0])))
	
    # Return their response. Currently only returning the value, but could also return a note (for questions) and the name of the response
    return (val, "", "")

#Establish a connection to a Workflow database
conn = arcpy.wmx.Connect(r'c:\test\Workflow.jtc')

#Get a Job for Execution
job = conn.getJob(77601)

try:
	#Execute the current Step in the workflow
	result = job.executeStep(callback=callback)
    
	print ("Executing the first step returned %i" % result.returnCode)
	
	#Run the next Step in the workflow
        result = job.executeStep(callback=callback) 
    
	#Mark the step as complete
	job.markStepAsComplete(callback=callback)
