How to stop rails from parsing json postgresql field to hash

Question

I am in search of a way to tell rails to parse json and jsonb data from postgresql column to a different Class or simply stop it from parsing it to an Hash as I won't use the hash.

I useread_attribute_before_type_cast, but the type cast is wasteful for my application.

Thank you

This is my finding, it is not complete but solve my problem. I wrotte/found a serializer to deal with the json column.

In the model:

serialize :profile, HashSerializer

And the serializer is defined like this:

class HashSerializer
  def self.dump(hash)
    hash.to_json
  end

  def self.load(hash)
    (hash || {}).with_indifferent_access
  end
end
