Rails Devise生成错误

Question

I'm fairly new to rails and I'm trying to set up devise and omniauth to allow users to login to my website with the Facebook API. I'm using this tutorial http://www.ruby-on-rails-outsourcing.com/articles/2012/01/20/adding-facebook-auth-to-rails-3-1-app/ to do this. However, when I try to run rails generate devise User , I get this error: undefined local variable or method config for main:Object (NameError) . How do I fix this?

devise.rb file :

Devise.setup do |config|
  config.mailer_sender = "please-change-me-at-config-initializers-devise@example.com" 
  require 'devise/orm/active_record'
  config.case_insensitive_keys = [ :email ]
  config.strip_whitespace_keys = [ :email ]
  config.skip_session_storage = [:http_auth]
  config.stretches = Rails.env.test? ? 1 : 10
  config.reconfirmable = true
  config.reset_password_within = 6.hours
  config.sign_out_via = :delete

development.rb:

*******::Application.configure do
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.cache_classes = false
  config.whiny_nils = true
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.action_dispatch.best_standards_support = :builtin
  config.active_record.mass_assignment_sanitizer = :strict
  config.active_record.auto_explain_threshold_in_seconds = 0.5
  config.assets.compress = false
  config.assets.debug = true
end

I had the exact same problem. abhas in the comments helped me get on the right track!

I had put config.assets.initialize_on_precompile = false in outside the Module ApplicationName block in the config/Application.rb folder. I put that config line in the Module block, and everything started working great!

module VitogoWeb2
  class Application < Rails::Application

    # A devise setting to prevent Heroku from accessing the DB or load models when precompiling the assets.
    config.assets.initialize_on_precompile = false

  end
end
