This allows declaring an enum on a String column as easily (and clearly) as with an Integer column.

For example:

string_enum :upload_status, [:pending, :complete, :error], _prefix: :upload

(As opposed to:)

enum :upload_status, {
  pending: "pending", 
  complete: "complete", 
  error: "error",
}, _prefix: :upload
