How to define a hash object in GraphQL

If your model has a json field or a serialized hash that you want to expose as a ObjectType, just specify the hash_key for each field: 

UserPreferenceType = GraphQL::ObjectType.define do
  field :name, types.String, hash_key: 'name'
  field :value, types.String, hash_key: 'value'
end
