# This monkey patch intends to solve cache errors on development environment when config.cache_classes = false.
# In order to use it you need to put it into you lib/ folder and
# insert "require File.join(RAILS_ROOT, 'lib', 'no_store_cache_monkey_patch')"
# after the "require File.join(File.dirname(__FILE__), 'boot')" line in config/environment.rb:


module ActiveSupport
  module Cache
    class NoStore < Store
      def read(name, options = nil)
        super
        nil
      end
    end
  end
end

module Rails
  class Configuration
    class << self
      alias :old_initialize :initialize
    end

    def initialize
      raise 'deu pau'
      self.old_initialize
      self.cache_store = default_cache_store
