Yeah I think for me I solved this by moving the project and data to a different drive. I believe my shared network drive was experiencing some connectivity issues.

I was wondering if someone can point me in the direction of the simplest method of creating a mobile routing application form a point feature layer in arcgis online map. Just wishing to use users current location from mobile device and route to selected point from published feature layer. Anyway there are alot of options and getting a bit overwhelmed. Suggestions are appreciated.

Thank you all!! You all seem very knowledgeable and have provided much useful info. Josh your query statement is precisely what I am looking for with this thread. Below is the complete code for this operation I am posting for the archives. # get unique list of values values = [row[0] for row in arcpy.da.SearchCursor(fc, (field))] query = "Value IN ({})".format(str(values).strip('[]')) # Extract Features where Value is in values attExtract = ExtractByAttributes(name, query) attExtract.save("Extract_landuseRaster") landuseRasterWeighted = "Extract_landuseRaster"

Hi Dan. Thanks for chiming in. I am just trying to return a list of unique values. This revised portion of the script may have been less confusing. This one was also successful in printing the list in the desired format. How can I use this now in my sql expression? # Use SearchCursor with list comprehension to return a # unique set of values in the specified field # values = [row[0] for row in arcpy.da.SearchCursor(fc, (field))] uniqueValues = (values) print(uniqueValues) Thank you for your help with this!

I am getting an incorrect SQL statement while trying to extractby attributes where item is in list. Can somebody help me form the correct SQL statement? Line 30 below... import arcpy import os arcpy.env.overwriteOutput = 1 # Check out any necessary licenses arcpy.CheckOutExtension("Spatial") base = r'C:\Users\Noah\Desktop\LCP Example\Scratch.gdb' name = "landuse_Clip" fc= os.path.join(base,name) field = "Value" arcpy.env.workspace = base # Use SearchCursor with list comprehension to return a # unique set of values in the specified field # for row in arcpy.da.SearchCursor(fc, "Value"): values = [row[0]] query = "Value" in values # Extract Features where Value is in values attExtract = ExtractByAttributes(name, query) attExtract.save("Extract_landuseRaster") landuseRasterWeighted = "Extract_landuseRaster"

Thanks for the response Tobias. I have rolled this over into a new discussion while trying a different approach maybe you can help? XSL Hide field name for image url

I am attempting to configure html popup. I would like for field to display text 'WAFWA', but provide link to url. Similar to basic html structure:<a href="http://www.wafwa.org">WAFWA</a> Can this be done? Thanks in advance, Noah

I am receiving the error that variable row is not defined (second line of codeblock). I am attempting to check "constraints_Merge_fl" against code value in "lepc_clip_fl". What does the correct usage of this variable in the codeblock look like? fc = "lepc_clip" code = "CODE" field = "OBJECTID" # Make fl's for select tools arcpy.MakeFeatureLayer_management(fc,fc + "_fl") arcpy.MakeFeatureLayer_management("constraints_Merge","constraints_Merge_fl") cursor = arcpy.SearchCursor(fc + "_fl") row = cursor.next() arcpy.AddField_management("constraints_Merge_fl","HEX_ID","Long") chat_List = [] while row: code_Value = row.getValue(code) hex_ID = row.getValue("Hex_ID") chat_List.append(hex_ID) for feature in chat_List: arcpy.SelectLayerByAttribute_management (fc + "_fl","NEW_SELECTION",'"Hex_ID" = {}' .format(feature)) arcpy.SelectLayerByLocation_management("constraints_Merge_fl",'intersect', fc + "_fl") expression = "getClass(int(!CODE!))" # Check syntax for row.getValue(code) in codeblock codeblock = """def getClass(code): if code < row.getValue(code): return row.getValue(code) else: return code""" arcpy.CalculateField_management("constraints_Merge_fl", "CODE", expression, "PYTHON_9.3", codeblock) row = cursor.next() Thanks in advance.

I am probably overlooking something, however I have not been able to find any way to round relative scale. Has anyone done this via interface or programmatically? Any suggestions? Sp. instead of 1inch -= 59 feet. Display 1 in = 60 feet. Thanks in advance, Noah

‎08-08-2014

Thanks all for the input! Duncan your reply provided exactly what was needed. Here is what worked for me... whereClause = """"{}" = '{}'""".format(field, filename) cursor = arcpy.UpdateCursor(fc, whereClause) Thanks again, Noah

Thanks for the reply Duncan. Could you provide an example of this?

I am attempting to search directories and sub directories for file in 'name' and return full file path of found file in a new field. When I print the value of variable 'string' it prints the desired results However after the script runs the field is populated with a single value instead of unique values for each subsequent row. Can anyone tell me why this is? # Set local variable source = 'R:\\' fc = "I14__ATTACH_TEST" field = "ATT_NAME" addfieldName = "fullPath" fieldLength = 200 # Add field arcpy.AddField_management(fc, addfieldName, "TEXT", "", "", fieldLength) ### Attempting to search directories and sub directories for file in 'name' ### and return full file path of found file (name) sc = arcpy.SearchCursor(fc) names = [] for scrow in sc: names.append(scrow.getValue(field)) for root, dirnames, filenames in os.walk(source): for filename in filenames: if filename in names: string = os.path.join(root, filename) cursor = arcpy.UpdateCursor(fc) row = cursor.next() while row: # field2 will be equal to field1 multiplied by 3.0 row.setValue(addfieldName, string) cursor.updateRow(row) row = cursor.next()

Thanks Don! Was still getting familiar with new design. Better now!

This was completely my fault these were all great responses and correct answers for what I have provided here! It turns out I was confusing the script name for script label. Thus... pythonaddins.GPToolDialog(toolPath,"GetIRCount") instead of... pythonaddins.GPToolDialog(toolPath,"Get IR Count") Which is what is displayed in arc catalog. Thank you both for your time and valuable input!!
