Just wanted to add this for future generations who are still working with ArcGIS Server-based Feature Services and want to use arcpy/Python to authenticate via token to do stuff. I could not get any of the above to work in my environments (10.8, 10.6.1), but found an outstanding Python toolset called 'restapi' that is great if you still need to run things on Python 2.7.x and more traditional ArcGIS Servers (that are not Portal). Authenticating is easy (token) Editing is easy (including adding/editing attachments for feature services) Highly recommend this repository!

I found this thread because I was experiencing the same issue as Clare.  After some fiddling around, I believe I have figured out what the issue is.  When using a Single Choice control on a field, the label/description of the choices cannot be too long.  For example: I add a single choice control to my survey (using the Web designer). One of my choices was - Commercial Delivery Truck (Fedex, UPS, etc) After adding the remaining choices and pressing the Save button, the following error shows:  "Error when parse form". When pressing the details dropdown, it reveals the name of your question > Choices[11]:   I deduced that the 10th or 11th option down was my really long choice (see #2) above.  After shortening it to Commercial Delivery Truck, saving the form was successful with no errors. Hope this helps someone out there, James ... View more

Hi Brad -  I'm picking up this conversation and wanted to know if you had any luck fine-tuning your network?  I'm having a similar issue with unexpected route results. Thanks! ... View more

DC DOT is currently sharing crash data to the public. We have redacted PII and have attempted to provide a decent summary of relevant attributes. It’s not perfect, but very useful to the general public. Currently, the update frequency is twice a year or so; in the next week we plan to change this to nightly updates. http://opendata.dc.gov/datasets/crashes-in-the-district-of-columbia Thanks, James K.

The responses here identify the problem, but the resolution is actually present in the ArcGIS/ArcMap documentation here: Calculate Field examples—Help | ArcGIS for Desktop A slight tweak the examples gives the resolution, using the Field Calculator: arcpy.time.ParseDateTimeString(!field1!) + datetime.timedelta(hours=12) ...

    with arcpy.da.UpdateCursor(FClassOrTable, fields) as cursor:          for row in cursor:              row[1] = GetMmax(row[0]) Instead of using a function to breakdown that Mmax value, you could also just use the extent object, which comes as part of the Shape@.  Like this:     with arcpy.da.UpdateCursor(FClassOrTable, fields) as cursor:          for row in cursor:              row[1] = row[0].extent.MMax ...

Peter, I have yet to find a workaround, but Richard's suggestion seems promising.  I hacked an ugly workaround (even more ugly than what's above :D), but will give Richard's suggestion a try to see if this works. Seems to me that the info stored in my dict() is just fine.  I can enter a set of keys, and return the data just fine if I'm at a break.  I'm a little baffled as to why it won't store on the row even though the data seems perfectly legit.  :confused: Thanks for both your and Richard's comments.                           try:                                         ID_check = entry[0]                                         print entry[0]                                         intable = "in_memory\ID_Check"                                         counter = 0                                         with da.SearchCursor(intable,["ID"]) as cursor:                                             for row in cursor:                                                 if row[0] == ID_check:                                                     counter += 1                                                                                             if counter >= 1:                                             pythonaddins.MessageBox("This Feature's ID is a duplicate.  Solve thi                                                                                s error before continuing!","Error",0)                                             raise Exception()                                                                                 elif counter == 0:                                             print "All is good, this ID is not a duplicate."                                             cursor = arcpy.da.InsertCursor(intable,["ID"])                                             cursor.insertRow([ID_check])                                             del cursor                                             edit = da.Editor(workspace)                                             edit.startEditing(False,True)                                             edit.startOperation()                                                                                         with da.UpdateCursor(targetlayer,fields) as cursor:                                                 for row in cursor:                                                     row = entry                                                     print "row: {}".format(row)                                                     cursor.updateRow(row)                                                                                                 del cursor                                             del row                                             edit.stopOperation()                                             #edit.stopEditing(True)                                                                                                                             except Exception as e:                                         print e.message                                         print arcpy.GetMessages()                                                                             arcpy.RefreshActiveView()                                     print "Complete"                                 When using "print edit.isEditing" after each edit method they are all true.  When I uncomment the line edit.stopEditing(True) an exception is thrown before the print statement saying Start Edit Session.  This happens in a versioned sde environment.  When using the same code in a personal geodatabase the exception message states something like "unable to perform within an edit session." So my solution for sde is to comment out the stop editing method.  This works however if I create a feature then save edits.  If I later change the attributes or geometry of that feature the state of the geodatabase changes and the edits cannot be saved.  "Attempting to perform action on a closed state.  Unable to save edits." ...

Hi Wayne, thanks for your comment. Actually when populating the key in the first code block (4th or 5th) line, I am converting the OID to string when storing the key value.  If I didn't have the key (as text), then I would be getting some sort of python key error because it wouldn't exist in the dict.  It's finding it, but something else is going on, I believe. Your code looks sound except you forgot your populated 'myinfo' dictionary OID keys are integers...your 'lookup' update cursor code is attempting to use string keys.  That creates an exception which isn't really handled - I won't go into that, but you have enough to know how to modify your code. BTW, I may not know what the whole enchilada is on your OID handling -maybe you've got that adequately covered- but don't know how advisable it is to use the OID from one table to use in updating another table? So, bottom line, your code should at least run with "myinfo[row[3]]['...']" statements. Wayne ... View more

Rats.  I'm having a completely different issue (I think), but I truly appreciate your speedy reply, Dan.  I'll post a new (but related) question to the forums shortly.
