Question

Trying to create an IMGKit instance in one of my Rails controllers:

def wkhtmltoimage
  ...
  kit = IMGKit.new("http://#{request.host_with_port}/?auth_token=" + token)
  img = kit.to_img(:jpg)
  file = kit.to_file(Rails.root + "public/uploads/testimage.jpg")
  ...
end

When I load the page, I get this:

NameError in PagesController#wkhtmltoimage

uninitialized constant PagesController::IMGKit

In my Gemfile I’m including the proper gem:

gem 'imgkit'

Bundler installs it fine. When I run the Rails console it is there and works:

1.9.3p194 :005 > IMGKit.new("http://google.com")
 => #<IMGKit:0x007fb08d16a658 @source=http://google.com, @stylesheets=[], @options={}> 
1.9.3p194 :006 > 

Why would the class IMGKit work in the Rails console but not in the app? Any suggestions? Using RVM, Pow, Rails 3.2.6 (and all other gems work fine with that setup).

EDIT WITH ANSWER

Rebooting the pow server appears to have fixed the problem. Just put in terminal:

touch tmp/restart.txt

That should do it.
