recognize json and json attribute type defaults

[catmando]

Currently json and jsonb rails record attribute types will work, except that the dummy value will not be initialized if the schema specifies a default type. In other words lets say your migration specifies that a json column should have a default value of {abc: 12}. The HyperModel behavior should load the dummy value while waiting for the server to return with {abc: 12} instead it loads nil (which is an acceptable value for json and jsonb fields, so its nothing breaks.

To work around this include the following in some client-side file (at the beginning of hyperstack/models/application_record.rb works fine)

module ReactiveRecord
  class Base
    class DummyValue < BasicObject
      alias build_default_value_for_jsonb build_default_value_for_nil
      alias build_default_value_for_json build_default_value_for_nil
    end
  end
end if RUBY_ENGINE == 'opal'  # the guard is important if its a file that is compiled server side!
