WorkflowExecutionResult

Zusammenfassung

The WorkflowExecutionResult object provides the result of executing a step in the workflow.

Diskussion

The WorkflowExecutionResult object provides the return code, which indicates the status of the step's execution. Each step has its own valid return codes and they can be used to guide the path of the workflow.

Codebeispiel

WorkflowExecutionResult example

The following script shows how a return code can be obtained from a step's execution.

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) 

#Raised when a step in the workflow encounters an execution error	
except wmx.WorkflowExecutionStepError as e:
    print ("Step failed to execute:")
    print("-"*60)
    traceback.print_exc()
	
#Raised when a workflow encounters an execution error
except wmx.WorkflowExecutionError as f:
    print ("Workflow failed to execute:")
    print("-"*60)
    traceback.print_exc()
