Question
So I get a uninitialized constant Dalli (NameError) when I push my ruby on rails app to my staging on heroku, but it works fine in production. my production.rb and staging.rb files are the exact same except for a mailer host value. Could someone help? Thanks!

Solution
Have a look at your Gemfile:
group :production do
gem 'dalli'
end
Bundler does not load Dalli in your staging environment.
Either move it out of the :production group, so it's available in all environments, or add it to the :staging environment too.
