Undefined method `groups' error when running generate scaffold command - ruby-on-rails

I am absolutely new to Ruby and Rails and I am getting an error when running this command:
rails generate scaffold User name:string email:string
Here is the full error I am getting:
/Users/ad7863/rails_project/demo_app/config/application.rb:7: undefined method `groups' for Rails:Module (NoMethodError)
from /Library/Ruby/Gems/1.8/gems/railties-3.0.11/lib/rails/commands.rb:15:in `require'
from /Library/Ruby/Gems/1.8/gems/railties-3.0.11/lib/rails/commands.rb:15
from script/rails:6:in `require'
from script/rails:6
I am following the Ruby on Rails tutorial which can be found here.
I am using Rails version 3.0.11.
Anyone have any idea what I'm doing wrong?
Thanks.
Edit: the contents of my application.rb file:
require File.expand_path('../boot', __FILE__)
require 'rails/all'

# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))

On line 7 of your application.rb file, change:

to:
# Bundler.require(*Rails.groups(:assets => %w(development test)))

I18n deprecation warning when using ActiveModel without Rails

When I run Rspec on my models, I get this warning:
[deprecated] I18n.enforce_available_locales will default to true in
the future. If you really want to skip validation of your locale you
can set I18n.enforce_available_locales = false to avoid this message.
I saw a similar question where the solution was to set config.i18n.enforce_available_locales or
I18n.config.enforce_available_locales in my config/application.rb file. I tried both, but I still get the warning.
The test that gives me the deprecation warning does not use any Rails except for ActiveModel. Instead of requiring the default spec_helper, I created my own spec_helper that does not involve any Rails at all. I also tried setting enforce_available_locales in my custom spec_helper, but I got an uninitialized constant error.
How do I get rid of the deprecation warning?
Edit:
Here's the exact code in my config/application.rb from one of my attempts with enforce_available_locales
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)
module Microblog
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de
I18n.config.enforce_available_locales = true
end
end
There's also a bug reported on i18n in Github regarding this (svenfuchs/i18n#223) and it was said to be fixed in i18n gem version 0.6.9.
So the solution I think is to require '>= 0.6.9' in our Gemfile.
gem 'i18n', '>= 0.6.9'
and do a bundle update.
Then do as below:
config/application.rb
I18n.enforce_available_locales = true
# If you set the default_locale option you should do it after the previous line
# config.i18n.default_locale = :de
Ref: https://github.com/rails/rails/issues/13159
Hope it helps :)
What seems to work is adding these lines to my spec_helper:
require 'i18n'
I18n.config.enforce_available_locales = true
Because my tests don't use Rails, the Application class goes untouched, so enforce_available_locales must go in the spec_helper itself. The first line gets rid of the uninitialized constant error.

Set language in Devise

I am a noob in Ruby/Rails and I am creating my first project now.
I am using Devise gem for authentication system. I have installed it and I am on fight to change the default messages from "en" (default language) to "pt-BR".
I have a file called devise.pt-BR.yml inside /config/locales/ with all translations for this language and I have followed a few tips but when I restart the server, I still get "en" as the default language.
I don't want to have two or more languages, I just need to work with "pt-BR" instead "en".
My environment:
Fedora 16
Ruby 1.9.2p320
Rails 3.2.6
Devise 2.1.2
/config/application.rb content (look at bottom):
require File.expand_path('../boot', __FILE__)

config.i18n.default_locale = :"pt-BR"
I18n.locale = :"pt-BR"
end
end
Change the line
config.i18n.default_locale = :"pt-BR"
to
config.i18n.default_locale = "pt-BR"
I was wrong, it's working!
I had to drop it inside application.rb:
config.i18n.load_path += Dir[Rails.root.join('locales', '*.{rb,yml}').to_s]
config.i18n.default_locale = :'pt-BR'
And put "devise.pt-BR.yml" inside /config/locales/
I was looking for "Sign in" and label from fields at "Log in" view but I think these strings are not translatable, I will generate these views and manually revise them.
Thank you.
Try renaming your locale file to pt-BR.yml, or else change your reference in application.rb to devise.pt-BR.yml.

application.rb paths.app.views undefined method `app' for Rails::Paths::Root

using devise 2.1.0
I had to override the devise registration controller. In the process I had to move my devise views directory to correspond with the new controller. I have this code in my config/applications.rb file
paths.app.views << "app/views/devise"
And it is throwing an error when I try and start my server with rails s:
...config/application.rb:65:in `<class:Application>': undefined method `app' for #<Rails::Paths::Root:0x00000103537740> (NoMethodError)
I am relatively new at rails. But I get that there is a root class somewhere that didn't define app. I got this advice to use this paths.app.views here at stack.

By reading the last comment of yours, it sound that you want either view_paths= or prepend_view_path.
Those can be set at class level in your controller.
If that isn't what you are looking for, consider reading Override devise registrations controller for information.

can't modify frozen array (TypeError) - config/application.rb:42:in `<<':

I have a rails 3 app, and am trying to do testing. I do the following command rspec spec/controllers/ and get the following error:

end
end
has anyone else experienced this exact kind of problem. If so how do you fix it because I have deleted my project and did a git clone all over and still get the same error.
Try the method the comments suggest:
config.autoload_paths += %W{#{config.root}/lib}
This doesn't modify the initial array, but adds the given array to config.autoload_paths and saves it into a new array in config.autoload_paths.

Rake task on rails 3 - config not found

Releated to this: Rake on Rails 3 problem
I'm trying to copy a rake task working under rails 2, into a rails 3 app.
The rake task is the following:
namespace :cached_assets do
desc "Regenerate aggregate/cached files"
task :regenerate => :environment do
include ActionView::Helpers::TagHelper
include ActionView::Helpers::UrlHelper
include ActionView::Helpers::AssetTagHelper
stylesheet_link_tag :all, :cache => CACHE_CSS_JS
javascript_include_tag "a.js", "b.js",
"c.js", :defaults, :cache => CACHE_CSS_JS
javascript_include_tag "q.js", "w.js",
"e.js", :cache => 'abc'
end
end
On Rails 2 it cache the assets correctly, on rails 3 I have the following error:
rake cached_assets:regenerate --trace
(in /var/www/apps/****)
** Invoke cached_assets:regenerate (first_time)
** Invoke environment (first_time)

I had the same problem and found a solution here: http://railsforum.com/viewtopic.php?id=42282
Just prefix
stylesheet_link_tag
and
javascript_include_tag
with
ApplicationController.helpers.
then you shouldn't even have to include the ActionView helpers.
