You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base_object.rb
    path of file: ./repos/consuldemocracy/app/graphql/types
    
    the code of the file until where you have to start completion: module Types
  class BaseObject < GraphQL::Schema::Object
    def self.field(*args, **kwargs, &)
      super(*args, **kwargs, &)

      # The old api contained non-camelized fields
      # We want to support these for now, but throw a deprecation warning
      #
      # Example:
      
    
    def self.field(*args, **kwargs, &)
      super(*args, **kwargs, &)

      # The old api contained non-camelized fields
      # We want to support these for now, but throw a deprecation warning
      #
      # Example:
      # proposal_notifications => Deprecation warning (Old api)
      # proposalNotifications => No deprecation warning (New api)
      field_name = args[0]

      if field_name.to_s.include?("_")
        reason = "Snake case fields are deprecated. Please use #{field_name.to_s.camelize(:lower)}."
        kwargs = kwargs.merge({ camelize: false, deprecation_reason: reason })
        super(*args, **kwargs, &)
      end
