Still struggling a bit with the FeatureLayerManager class and when to use add_to_defintion, updateDefinition or delete_from_definition. This time, I am trying to enable editing and editor tracking on a hosted feature service. I started by opening up the Chrome developer tools Network monitor, then on the Feature Layer settings page I manually checked the options 'Enable editing', 'Keep track of created and updated features' and 'Keep track of who created and last updated features', then hit Save. I then saw the console send an update_definition request.   I copied the form data and popped that into my update_definition method in my python notebook @ line 13     # Convert to a Spatially Enabled Dataframe sdf = pd.DataFrame.spatial.from_xy(df, "lon_y", "lat_x", sr=4326) print('Publishing layer...') item = sdf.spatial.to_featurelayer('myFeatureLayer', tags=["test"], folder="My Folder") print("Deleting interim fGDB...") interimGDB = gis.content.get(gis.content.search(query="title:myFeatureLayer", item_type="File Geodatabase")[0].id).delete() featureLayer = gis.content.get(item.id).layers[0] print("Enabling Change Tracking...") resp = featureLayer.manager.update_definition({ "hasStaticData":False, "capabilities": "Query, Editing, Create, Update, Delete, ChangeTracking", "editorTrackingInfo":{ "enableEditorTracking":True, "enableOwnershipAccessControl":False, "allowOthersToUpdate":True, "allowOthersToDelete":True, "allowOthersToQuery":True, "allowAnonymousToUpdate":True, "allowAnonymousToDelete":True} }) print(resp) print(featureLayer.properties)             Reviewing the properties/definition however, I noticed that under nothing in the definition actually was updated, other than 'hasStaticData' which was changed from False to True. 'ChangeTracking' is not listed as a capability and the editorTrackingInfo array is not present in the updated definition.   ... View more

Have been tinkering with this for the better part of a day and can't figure it out.  I'm calling an API to get a json response containing store locations, which contain the coordinates, then pushing that into a Feature Layer. Esri's implementation of the Spatially Enabled Dataframe's .to_featurelayer has the unfortunate behavior of sanitizing column names, even if the column names are valid to begin with. The result is that its changing my column names from their original case to snake_case. For example 'storeName' gets changed to 'store_name' when I utilize the .to_featurelayer method to publish the data frame as a feature layer, even though there is absolutely nothing invalid at all about a feature layer with a field named 'storeName'. Unlike the .to_featureclass method, where sanitize_columns is exposed as a parameter in the method and defaulted to True, meaning you can set it to False to avoid this behavior, sanitize_columns is defaulted to to True in the .to_featurelayer method and is not exposed as a parameter so there is no way to avoid it. As a result, I'm trying to go back and update the column names using the update_definition method on the feature layer manager but I keep getting one of two errors.  The first approach I took:   from arcgis.features import FeatureLayer featureLayer =gis.content.get("c952e9e257bd4fc887be2934291548cb") lyr = featureLayer.layers[0] lyr.properties originalDefinition = lyr.properties # Get the fields array originalFields = originalDefinition["fields"] newFields = originalFields.copy() for f in newFields: if "_" in f["name"]: newFieldName = f["name"].split("_")[0].lower()+f["name"].split("_")[1].title() f["name"] = newFieldName #newFields print('"fields": ' + json.dumps(newFields)) lyr.manager.update_definition('"fields": ' + json.dumps(newFields))   Fails with:   --------------------------------------------------------------------------- Exception Traceback (most recent call last) <ipython-input-28-34cef8ca738c> in <module> 13 #newFields 14 print('"fields": ' + json.dumps(newFields)) ---> 15 lyr.manager.update_definition('"fields": ' + json.dumps(newFields)) /opt/conda/lib/python3.7/site-packages/arcgis/features/managers.py in update_definition(self, json_dict) 2002 u_url = self._url + "/updateDefinition" 2003 -> 2004 res = self._con.post(u_url, params) 2005 self.refresh() 2006 return res /opt/conda/lib/python3.7/site-packages/arcgis/gis/_impl/_con/_connection.py in post(self, path, params, files, **kwargs) 718 file_name=file_name, 719 try_json=try_json, --> 720 force_bytes=kwargs.pop('force_bytes', False)) 721 #---------------------------------------------------------------------- 722 def put(self, url, params=None, files=None, **kwargs): /opt/conda/lib/python3.7/site-packages/arcgis/gis/_impl/_con/_connection.py in _handle_response(self, resp, file_name, out_path, try_json, force_bytes) 512 return data 513 errorcode = data['error']['code'] if 'code' in data['error'] else 0 --> 514 self._handle_json_error(data['error'], errorcode) 515 return data 516 else: /opt/conda/lib/python3.7/site-packages/arcgis/gis/_impl/_con/_connection.py in _handle_json_error(self, error, errorcode) 534 535 errormessage = errormessage + "\n(Error Code: " + str(errorcode) +")" --> 536 raise Exception(errormessage) 537 #---------------------------------------------------------------------- 538 def post(self, Exception: Unable to update feature service layer definition.

Looking for a widget in  JSAPI 4.x that would allow me to pass a layer object and have a list view model displayed as a sidebar in my app. Kind of ArcGIS Workforce style, like the below I came across LayerList-LayerListViewModel in my search, but that seems to display a ListViewModel of all of the layers in the map, allowing the user to reorder those layers and toggle visibility and such. Similar to what I am looking for, but I just want to be able to pass a layer object and list the features within the given layer in a ListViewModel ... View more

We have an ArcGIS Pro Addin that we deploy to all end user systems via the AddinFolder registery key. As explained by @Wolf in this post, the process that a ProAddin follows when using this mechanism for Addin deployment is: Each time Pro starts up, Pro checks the well-known addinFolders locations for esriAddinX files, and unzips the add-in content (in the 'esriaddinx' file) under the log-in user profile folder: ...\AppData\Local\ESRI\ArcGISPro\AssemblyCache.   When the add-in is instantiated by Pro that folder location (…\AppData\Local…) is used to load the Dlls required to run the add-in. If you delete the AssemblyCache folder completely step 1. above will repeat. What's not stated is that this also works for distributing updates. Somewhere behind the scenes, there is probably some checksum wizardry going on to see if the files in the assembly cache match the files in well-known addinFolder to determine if it needs to unzip the remote addin again. Also, if you delete an addin file from the remote folder, it gets removed from the local assembly cache. All of this is great and it works pretty smoothly, but we'd like to not be required to use a publicly accessible shared drive. We already keep all of the source for our addins in a Git repo wth releases for each new update of the addin. Is there any way to set up a Pro Addin to download the esriAddin file from a Git repo, and always check for new releases from that repo?  ... View more
