I'm using ArcMap 10.2.1 and Python 2.7.5.
I would like my updateParameters to enable and disable fields based on if a feature is a point or a polygon. If the point is selected then I need the measure. If the line is selected then I need the begin measure and the end measure. I am getting a similar error as coolDude when I open my tool in ArcMap.
There is an excellent discussion that almost answers my question posted here: How do updateParameters and updateMessages Interact in a Python Toolbox?
The questioner (coolDude) had two related questions that also got very close to answering my question. However, the tool I am writing is comparing either two point features, a point and a line feature, or two line features.
The error suggest that my describe method is incorrect. Python developers, am I using the syntax incorrectly? I checked out my code in the console and I got the desired effect.
Here is my getParameterInfo method:
input_base_feature = arcpy.Parameter(displayName="Base Feature", name="input_base_feature", datatype="GPFeatureLayer", parameterType="Required", direction="Input") params.append(input_base_feature) input_base_id_field = arcpy.Parameter(displayName="Base Feature ID Field", name="input_base_id_field", datatype="Field", parameterType="Required", direction="Input") input_base_id_field.parameterDependencies = [input_base_feature.name] params.append(input_base_id_field) input_base_measure_field = arcpy.Parameter(displayName="Base Feature Measure Field", name="input_base_measure_field", datatype="Field", parameterType="Required", direction="Input") input_base_measure_field.parameterDependencies = [input_base_feature.name] input_base_measure_field.filter.list = ['Float', 'Double'] params.append(input_base_measure_field) input_base_begin_measure_field = arcpy.Parameter(displayName="Base Feature Begin Measure Field", name="input_base_begin_measure_field", datatype="Field", parameterType="Required", direction="Input") input_base_begin_measure_field.parameterDependencies = [input_base_feature.name] input_base_begin_measure_field.filter.list = ['Float', 'Double'] params.append(input_base_begin_measure_field) input_base_end_measure_field = arcpy.Parameter(displayName="Base Feature End Measure Field", name="input_base_end_measure_field", datatype="Field", parameterType="Required", direction="Input") input_base_end_measure_field.parameterDependencies = [input_base_feature.name] input_base_end_measure_field.filter.list = ['Float', 'Double'] params.append(input_base_end_measure_field) Further down in the code, I use the updateParameter method:
desc_base = arcpy.Describe(parameters[4].value) if desc_base.shapeType == 'Point': parameters[6].enabled = True, parameters[6].parameterType = 'Required', parameters[7].enabled = False, parameters[7].parameterType = 'Optional', parameters[8].enabled = False, parameters[8].parameterType = 'Optional' elif desc_base.shapeType == 'Polyline': parameters[6].enabled = False, parameters[6].parameterType = 'Optional', parameters[7].enabled = True, parameters[7].parameterType = 'Required', parameters[8].enabled = True, parameters[8].parameterType = 'Required' else: arcpy.AddMessage("Incorrect type for input_base_feature. Point or polyline features only.") My guess is
desc_base = arcpy.Describe(parameters[4].value) Is incorrect. The other error I get has to do with the line:
parameters[6].parameterType = 'Required', I tried it without comments and I tried replacing the .value with .valueAsText and I got the same errors. Speaking of, here are the errors:
When I select a Centerline:
Traceback (most recent call last): File "C:\Workspace\qcerator\src\eaglepyqc\toolboxes\check_for_overlaps.py", line 147, in updateParameters desc_base = arcpy.Describe(parameters[4].value) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\__init__.py", line 1234, in Describe return gp.describe(value) File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\geoprocessing\_base.py", line 374, in describe self._gp.Describe(*gp_fixargs(args, True))) AttributeError: Object: Error in parsing arguments for Describe When I select a Base Feature (line):
Traceback (most recent call last): File "C:\Workspace\qcerator\src\eaglepyqc\toolboxes\check_for_overlaps.py", line 153, in updateParameters parameters[8].enabled = False TypeError: list indices must be integers, not tuple When I select a Base feature (point):
Traceback (most recent call last): File "C:\Workspace\qcerator\src\eaglepyqc\toolboxes\check_for_overlaps.py", line 150, in updateParameters parameters[6].enabled = False TypeError: list indices must be integers, not tuple And finally, a screenshot of the toolbox so you can see the whole thing. I left out lines of code that sets up the Centerline and cross feature inputs for the sake of brevity.
The reason I put in the lines with "required" or "optional" is I still get the green dots next to the grayed-out fields. Furthermore, the fields only get grayed-out if a polyline is selected. The if statement doesn't work if a point feature class is selected from the drop-down menu.
This is a complicated problem. Thank you for reading to the end!
