Question

I just switched to Devise/Omniauth combo and everything is working properly on my localhost server. However when I uploaded to heroku the app crashes when the user clicks sign up on the traditional sign up form (not omniauth login). I am using rails 3. My logs say

LoadError (no such file to load –bcrypt):
app/controllers/registrations_controller.rb:11 in ‘build_resource’
app/controllers/registrations_controller.rb:4 in create’

The referenced controller:

class RegistrationsController < Devise::RegistrationsController

  def create
    super
    session[:omniauth] = nil unless @user.new_record?
  end

  private

  def build_resource(*args)
    super
    if session[:omniauth]
      @user.apply_omniauth(session[:omniauth])
      @user.valid?
    end
  end 
end

Line 4 and 11 are the super since the registration controller is overriding Devise. What’s going wrong? Thanks.

Make sure you have:

gem 'bcrypt-ruby'

in your Gemfile. If not, add it and run

bundle install

Also, you may have to delete your Gemfile.lock and try to push to Heroku again.
