arcpy.ListSubtypes is not working

MoizIshfaq — Sun, 12 May 2013 12:22:20 GMT

Hello,
I am following ESRI Documentation link 'http://resources.arcgis.com/en/help/main/10.1/index.html#//018w00000021000000' to print the details of subtype associated with a feature class but for some reason am always getting an error message complaining arcpy doesn't contain a definition for ListSubtypes(table_name) method.

Here is the code snippet,

          subtypes = arcpy.ListSubtypes(table_name)           for stcode, stdict in subtypes.iteritems():             print('Code: {0}'.format(stcode))             for stkey in stdict.iterkeys():                 if stkey == 'FieldValues':                     print('Fields:')                     fields = stdict[stkey]                     for field, fieldvals in fields.iteritems():                                         print(' --Field name: {0}'.format(field))                         print(' --Field default value: {0}'.format(fieldvals[0]))                         if not fieldvals[1] is None:                             print(' --Domain name: {0}'.format(fieldvals[1].name))                 else:                                         print('{0}: {1}'.format(stkey, stdict[stkey]))

Here is the error message,

[HTML]PYTHON ERRORS:
Error Info:
'module' object has no attribute 'ListSubtypes'
Exception Type is: <type 'exceptions.AttributeError'>
Traceback info:
File "\\machine_name\published_folder\GPT\listAllDataObjFieldsNamesTypes.py", line 72, in <module>
subtypes = arcpy.ListSubtypes(schemaObject)
[/HTML]

Secondly, I was wondering if there is anyway we can get a subtype values instead of codes. I know I can use a search cursor to get the distinct values from a featureclass for the subtype field but that won't give me the actual values associated with these codes. Kindly share your thought on it.

I am using ArcGIS Desktop 10.1 with ArcSDE 10 (64bit Oracle 11g).

In advance I thank you all for your time and support.

subtypes = arcpy.ListSubtypes(table_name)

Britt, this method is within the arcpy.da module. The code example is a bit weak in the help; I complained in the feedback - and I suggest you do too!

Have you tried:

subtypes = arcpy.da.ListSubtypes(table_name)

Secondly, I was wondering if there is anyway we can get a subtype values instead of codes.

I'm pretty sure the most direct approach would be to examine the associated domain with arcpy.da.ListDomains.

Thanks Curtis for your quick reply and help. It indeed answered both of my questions like a charm.
