I have a service that chooses whether to give a field one value or another depending on what's present in the data already. When I run the python script outside of the server, it runs fine. When I run it on the server, it fails because it doesn't recognize the uuid module in the code block. I think it's treating uuid as a string, but to use code blocks you pass in the whole code block as a string. Has anybody successfully used code blocks in their GP services? def getTractID ( isDuplicate ) : import uuid if isDuplicate == 'dupe' : tractID = '{' + str ( uuid . uuid4 ( ) ) + '}' tractID = tractID . upper ( ) arcpy . RemoveJoin_management ( mgmtTractFL ) with arcpy . da . UpdateCursor ( mgmtTractFL , 'MgmtTractID' ) as uCursor : for row in uCursor : row [ 0 ] = tractID uCursor . updateRow ( row ) del uCursor arcpy . AddJoin_management ( mgmtTractFL , 'OBJECTID' , duplicatePolys , 'IN_FID' ) else : codeblock = """def ID(): return '{' + str(uuid.uuid4()) + '}'""" expression = 'ID().upper()' arcpy . CalculateField_management ( mgmtTractFL , 'MgmtTractID' , expression , 'PYTHON' , codeblock ) On my server it converts 'ID().upper()' into a g_ESRI_variable. I still don't get why it would affect it's efficacy though. The 'expression' variable would still be a string. g_ESRI_variable_3 = u 'ID().upper()' g_ESRI_variable_4 = u 'MgmtTractID' def getTractID ( isDuplicate ) : import uuid if isDuplicate == 'dupe' : #stuff else : codeblock = """def ID(): return '{' + str(uuid.uuid4()) + '}'""" expression = g_ESRI_variable_3 arcpy . CalculateField_management ( mgmtTractFL , g_ESRI_variable_4 , expression , 'PYTHON' , codeblock ) If this can't be figured out, I can always use a cursor but I figure CalculateField would be faster when there's 1000+ records.

Geoprocessing services not agree with code blocks?

On my server it converts 'ID().upper()' into a g_ESRI_variable. I still don't get why it would affect it's efficacy though. The 'expression' variable would still be a string.

Just for fun, can you try importing uuid inside the codeblock?

That did the trick, thanks.

codeblock <SPAN class="operator token">=</SPAN> <SPAN class="string token">"""def ID():
                import uuid
                return '{' + str(uuid.uuid4()) + '}'"""</SPAN>
expression <SPAN class="operator token">=</SPAN> <SPAN class="string token">'ID().upper()'</SPAN>

You may have to put the import uuid inside your quoted code block as well
