Question

I have a rails app set up with Nginx + Passenger. When i have rails_env development; on my nginx.conf everything works fine, but when I remove it so the app get server on production env it just doesnt work, seems like its not loading gems or something. Feel free to take a look at the errors here http://www.luisurraca.co.cc

error message:
undefined method `has_attached_file' for #<Class:0x00000003b0be10>
Exception class:
NoMethodError

Right now its referring to the paperclip gem, but if i start removing gems from the gemfile it will display error from some other gem and so on.

Any ideas what the issue might be?

Answer 1

You probably defined paperclip/whatever in development group and it is not installed with bundle install --deployment. To see installed gems do bundle show not gem list.

did you specify ruby path for nginx? it should look like this:

    http {
        passenger_root /home/rlisowski/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.13;
        passenger_ruby /home/rlisowski/.rvm/wrappers/ruby-1.9.3-p194/ruby; 
        # ....
