"uninitialized constant Users (NameError)" w/ Heroku deploy

Go To StackoverFlow.com

I've built a basic Rails app with Mongoid, Devise and Omniauth for Facebook login. I've got no problem running it locally, but when I try to push to Heroku, I'm getting this error:

"/app/app/controllers/Users/omniauth_callbacks_controller.rb:1:in `': uninitialized     constant Users (NameError)"

I've Googled the hell out of this with little luck. I've committed the User model, I've ran "heroku run rake db:migrate", etc. No luck. Here's my stack.

Controller:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
  # You need to implement the method below in your model
@user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)

if @user.persisted?
  flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook"
  sign_in_and_redirect @user, :event => :authentication
else
  session["devise.facebook_data"] = request.env["omniauth.auth"]
  redirect_to new_user_registration_url
end
end
end

Any thoughts ?

I had this issue; I know it's a late answer but I wanted to add this for whoever needed it.

Make sure that your OmniauthCallbacksController IS IN A users FOLDER. "app/controllers/users/omniauth_callbacks_controller.rb"

Unlikely, but if you used "rails generate scaffold", or "rails generate controller" to create the controller, you need to "git add -A" to add all the newly created files to your repository. (1) git add -A (2) git commit -m "new files added" (3) git push [assuming you're also using a remote repo] (4) git push heroku master (5) heroku run rake db:migrate

This would be a "Rookie Mistake", but would explain the error above. Don't ask how I know!

Just thought I'd add that I had this issue and that the above solutions didn't work for me. It turns out the cause in my case was that Devise had capitalized the Users subfolder's name (/app/app/controllers/Users). Deleting the folder from git and then readding it with the proper lowercase name of "users" (/app/app/controllers/users) solved my issue.
