graphql_controller.rb

class GraphqlController < ActionController::Base
  include Knock::Authenticable

  before_action :authenticate

  def execute
    # snip...
    context = {
      # Query context - +current_user+ is available when authenticated:
      current_user: current_user,
    }
    # snip...
    render json: result
  end
end
