set a field as unique using arcgis api for python

Question

Can you set a field as unique using the arcgis rest api for python?

You can, enabling unique values means adding an index with a unique constraint to the field.  To do this in the API you'll want to call the FeatureLayerManager's add_to_definition() function, passing in something like this:

{"indexes":[
  {"fields":"MyField",
   "isUnique":True,
   "description":"For uniqueness"}
