|

# The corresponding column is of type json, so there's no need for an explicit serializer
|
|
# But there's a subtle difference here from having a text field and defining `serialize :ips JSON`
|
|
# If a string is assigned to `ips` it is interpreted and parsed and JSON, and the result is nil
|
|
# if not valid JSON. With the serializer version, the string would be preserved as string.
