If you get this from your error log, there might be two things you might look into:
1. assets pipeline precompile
2. cache_store is not properly set up for the environment (like staging and production)
To precompile the asset pipeline, you need a Javascript runtime like node.js
Or you will see the error message when you run
rake assets:precompile Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
Write the code in /lib/global.rb
def hello; “world”; end
Autoload in /config/application.rb
config.autoload_paths += Dir["#{config.root}/lib/**.rb/"]

I found myself wanting to set an attr_accessor to handle passing a date to my model in a form_for tag with the f.datetime_select helper. So this is what I had:
Model:
attr_accessor :my_time
View:
<%= f.datetime_select :my_time %>
Unfortunately when I submit my form I get this:
1 error(s) on assignment of [...]
Add the following to your application.rb
class Application < Rails::Application config.sass.load_paths << “#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/compass/stylesheets” config.sass.load_paths << “#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/blueprint/stylesheets” end
When I try to move the Devise stuff into a module User::Devise and include it in class User, I got this warning ‘warning: toplevel constant Devise referenced by User::Devise’
Please see the code before and after for a solution.
Solution is to make User::Devise before you do the include for class User

So apparently the newest version of Rake (0.9+) breaks rails. You will get the error: WARNING: Global access to Rake DSL methods is deprecated. Please Include … Rake::DSL into classes and modules which use the Rake DSL methods. The quick fix is to downgrade to Rake 0.8.7, but you can also add this little [...]
