I keep losing a day when labeling with Arcade. I have a date field (not text) with manually entered dates, e.g., "5/1/2003". I did not enter any times. If I label it with Python by simply calling the date field, [Date], it returns exactly that date and formatting. If I call the field with Arcade, $feature.Date, it labels as: "2003-04-30T20:00:00-04:00". I figured out how to format the date: Text($feature.Date,'M/D/Y')‍, and though it's kind of annoying that that's necessary when using Arcade, I at least get it. But the head-scratcher is why I've lost a day. Note that the labeled date is 2003-04-30 (or 4/30/2003), not 5/1/2003 as it should be. I'm sure it has something to do with the time shift. But the question is, how do I prevent this from happening? Do I have to reformat my data? Seems silly that I should have to do that, but at least I'd know what to do. Or is there a way to leave the data as it is and use Arcade to re-format properly? Thanks! ... View more

I'm trying to split a string and label only a particular part of it. (I'm using Python because Arcade doesn't seem to have sufficient capability to specify which part of the string I want to label, but that's a separate gripe.) This expression cannot be verified if any nulls are present in the field: def FindLabel ( [ValMap] ): return [ValMap].split("_")[1]‍‍‍‍‍‍‍‍ You'll get this error: But you can get around that by putting an if statement in the expression: def FindLabel ( [ValMap] ): if [ValMap] != None: return [ValMap].split("_")[1]‍‍‍‍‍‍ But then I thought, "Wait, I shouldn't have to filter nulls in the expression; that's what the SQL query on the label class is for!" I had already applied this filter to the label class: SELECT * FROM FeatureClass WHERE ValMap IS NOT NULL‍‍ For testing, I applied the same SQL query to the definition query of the layer. Either way, it doesn't prevent the error on the expression. I thought maybe this is a bug in Pro but the same thing happens in ArcMap, which makes it less likely to be a bug(?). So now I just want to understand the mechanics of SQL queries on label classes and layer definitions, and their apparent (non-)effect on label expressions. ... View more

I have created a model that is intended to run on features I've selected interactively (manually) from the map. That is, feature selection is not part of the model - it is the expected input. The problem is, if there is no selection on a particular layer the model runs on every feature in that layer. I want to prevent this inevitable accident by putting a check into the model that stops it from running unless at least one feature in the layer is selected. (It's not obvious if features from the correct layer are selected due to multiple similar layers in the map. I am often toggling selectability and visibility of the layers.) The Get Count documentation has an example diagram using it as a precondition, which seems to be exactly what I need. But it doesn't work in my model, I assume due to my manual selection workflow. If I test my model with no selection, Get Count simply returns the number of (unselected) features in my layer. Thus, the count is always more than zero and fails to guard against proceeding without features having been selected. Here's a screenshot of the first part of my model with the attempted precondition: Is there a way to do what I'm envisioning? Perhaps this must be done with Python? I'm open to that, but I usually try ModelBuilder first since I'm more familiar with it. Thanks! ... View more

If I'm designing a new map or app to replace an old one, I don't want to simply delete the old one that many people have bookmarked. I also don't want them to continue using the old one, intentionally or not. As determined here, you cannot swap out one item for another using the same URL. Alternatively, I'd like to repurpose the old app's URL into a redirection notice. What is the best way to that? I could put a link to the new app in a splash widget (if it's possible to edit the app - see below), but that still allows the user to dismiss the notice and continue using the old app. (This is the best hack I could come up with: http://bit.ly/AGOLRedirectHack.) I could delete or disrupt the functionality of the map the app points to, but that isn't particularly elegant. (And there are probably some bookmarks pointing directly to the map rather than the app, which is another whole issue.) It would be nice if AGOL had some sort of built-in redirection method that notifies the user of the new app and makes the old app inaccessible. Marking the old app as deprecated could trigger this capability. Currently, deprecating an item does absolutely nothing to inform someone who arrives directly at the app (never having seen the item details page) about its status. For that matter, this functionality should exist for any kind of item in AGOL. Why would you need to create a whole new map or app rather than simply updating the old one? I can think of at least 2 scenarios: 1. The old app is so old or was originally made in whatever manner that there's no option to edit it through AGOL. (that is the problem I'm currently facing) 2. You want to develop and test a new app over a long period of time before making it live. Once it's ready, you'll swap out the old for the new. The second scenario especially seems like something that would be commonly desired, yet AGOL doesn't provide an easy way to accomplish. Unless I'm missing something, which is what I'm trying to figure out. Else, this post probably ought to be changed into a feature request. Thank you for any insight! ... View more
