I am developing a rails application which should send push notifications to iOS devices.

  • 0

I am developing a rails application which should send push notifications to iOS devices. I am using apn_on_rails gem. Everything works fine in the rails console. However when I run the server, I get undefined method errors for all the basic view methods such as content_for or form_tag etc:

When I take require 'apn_on_rails' from my development.rb out, the views work again, but of course without push notifications.

Here is an example trace:

Thanks for any help…

    It is not evident whether you call config.gem 'apn_on_rails' – it sounds more like you are require:ing the library, which probably is something you should not do at this point: the point of environment setup.

    Have the config.gem things in your environment setup (i.e. development.rb), but make eventual requires happen later (->in the controller / model / helper in question).
