activesupport

I couldn't really find this in Rails documentation but it seems like 'mattr_accessor' is the Module corollary for 'attr_accessor' (getter & setter) in a normal Ruby class . Eg. in a class class User attr_accessor :name def set_fullname @name = "#{self.first_name} #{self.last_name}" end end Eg. in a module module Authentication mattr_accessor :current_user def login @current_user = session[:user_id] || nil end end This helper method is provided by ActiveSupport . Avdi Rails extends Ruby with both mattr_accessor (Module accessor) and cattr_accessor (as well as _ reader / _writer versions). As

I'm in the process of upgrading a Rails 3.2 app to Rails 4.1. Whenever I try to start the console or server though, I come across this error: C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/active_support /core_ext/time/zones.rb:70:in `rescue in find_zone!': uninitialized constant TZI nfo::InvalidTimezoneIdentifier (NameError) from C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/a ctive_support/core_ext/time/zones.rb:55:in `find_zone!' from C:/Ruby200/lib/ruby/gems/2.0.0/gems/activesupport-4.1.0.beta1/lib/a ctive_support/railtie.rb:20:in `block in <class

How do I avoid the circular argument reference warning in activesupport. Happens on ruby 2.2.0 /home/ec2-user/apps/foo_prod/shared/bundle/ruby/2.2.0/gems/activesupport-3.2.21/lib/active_support/values/time_zone.rb:270: warning: circular argument reference - now /home/ec2-user/apps/foo_prod/shared/bundle/ruby/2.2.0/gems/ruby-ole-1.2.11.7/lib/ole/types/base.rb:265: warning: duplicated key at line 266 ignored: 4095 This is compass issue here . They haven't release new version yet so you may need to wait for it. Use Rails 3.2.22 gem 'rails', '3.2.22' OR warning fixes in version 1.2.11.8: bundle

I am wanting to test a function on one of my models that throws specific errors. The function looks something like this: def merge(release_to_delete) raise "Can't merge a release with itself!" if( self.id == release_to_delete.id ) raise "Can only merge releases by the same artist" if( self.artist != release_to_delete.artist ) #actual merge code here end Now I want to do an assert that when I call this function with a parameter that causes each of those exceptions, that the exceptions actually get thrown. I was looking at ActiveSupport documentation, but I wasn't finding anything promising. Any

Rails' ActiveSupport module extends the builtin ruby Time class with a number of methods. Notably, there is the to_formatted_s method, which lets you write Time.now.to_formatted_s(:db) to get a string in Database format, rather than having to write ugly strftime format-strings everywhere. My question is, is there a way to go backwards? Something like Time.parse_formatted_s(:db) which would parse a string in Database format, returning a new Time object. This seems like something that rails should be providing, but if it is, I can't find it. Am I just not able to find it, or do I need to write
