Delete Field from Feature Layer

Question

Hi

I have been trying to delete a field from a feature layer. I have tried "delete_from_definition" and I get a success response, and yet the field (column) is still there afterwards:

1. I have a layer object, named updater_layer (it is definitely a feature layer object, I have checked its properties).

2. I create the JSON that defines the column:

status_remove = {
 "name" : "STATUS", 
 "type" : "esriFieldTypeString", 
 "alias" : "Status", 
 "sqlType" : "sqlTypeOther", 
 "length" : 35, 
 "nullable" : 'true', 
 "editable" : 'true', 
 "domain" : 'null', 
 "defaultValue" : 'null'
 }

3. I use:

updater_layer.manager.delete_from_definition(status_remove)

{'success': True}

but when I look at the properties i.e.

updater_layer.manager.properties

The STATUS field is still there.

How do I remove a field from a feature layer in ArcGIS Online using the arcgis.gis API?

Thanks

Hugo

Hello Hugo, Here is how you would delete a field from a feature layer hosted in AGOL. import arcgis from arcgis.gis import GIS # Provide credentials to the GIS object. gis = GIS(username="your username", password= "your password") #Get the id of the hosted feature layer item = gis.content.get("id to the feature layer") #Get the actual feature layer fl = item.layers[0] #This is the JSON structure you need to pass in so that it knows what field to delete. # https://developers.arcgis.com/rest/services-reference/delete-from-definition-feature-layer-.htm json = { "fields" : [ { "name" : "POP90_SQMI" } ] } result = fl.manager.delete_from_definition(json) print(result)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
