My custom widget can read data from features but cannot edit them

[MedMZOURI]

Hey guys..My custom widget can read data from features but cannot edit them (writing in a field, inserting a row) which means the widget can read but not modify the features fields..How can I make my widget write in fields and insert rows???   (in arcgis desktop the script runs correctly so it can modify features and insert row..but in arcgis online no)

Is your code using a featuresever url or a mapserver? Editing is only supported when using a featureserver url.

Yes I am using a feature service layer..but in my code I'm using the local path of the layer  "C\ArcGIS\....." , should I use the url location "REST"?

OK. Let me check this. Do you know the difference between a FeatureLayer and a FeatureServer URL? Services in esri can come from a FeatureServer and a MapServer type url. You can use a FeatureServer or a MapServer endpoint in the url when you construct a FeatureLayer i code but the FeatureServer url will be the only one that allows editing. There is no using a local path...

I am using a hosted feature layer (a shared it as a map service in my local server) and in my script I used the local path , and this works correctly in arcgis desktop (I can read and edit data) but in web appbuilder I can only read..In what stage in my script should I use the REST URL of the layer? because I tried using the Rest url instead of the local path but it turns an error (in arcgis desktop) I used it in  "arcpy.da.editor("https:// REST URL") 
I heard about using Arcgis API for python..Do i need it?

Med,

   Your use of terms is really confusing. A Hosted feature layer means AGOL or on premise Portal and that would be a Feature Server Service (not a Map Service).

Next you are using python with I have no experience using so I need to let someone with Python experience answer.
