SuperCurrent

SuperCurrent takes away the need to define a Current class and instead makes it available from anywhere in your app without having to define it.

This means that your test coverage will not suffer from ActiveSupport::CurrentAttributes!

You can define the class name of the Current class, so if you're already using Current for something else, you can use a different name.

# config/initializers/super_current.rb
SuperCurrent.config.current_class_name = 'SuperCurrent'

Then you can have your existing Current class be a subclass of SuperCurrent and it will still work with all the exciting features of SuperCurrent.

class Current < SuperCurrent
  # ...
end

Usage

Just think up a name for your attribute and assign it! It will be created on the Current class automatically.

Current.foo = 'bar'
Current.foo # => 'bar'

SuperCurrent also adds the ability to use [] and []= to access the attributes.

Current[:foo] = 'bar'
Current[:foo] # => 'bar'

Even something like Current[:foo][:bar] will work!

# No need to define Current[:hoge] beforehand!
Current[:hoge][:bar] = "hello"
Current[:hoge][:bar] # => 'bar'

This means that you no longer need to define the attributes on the Current class beforehand.

So if you have a class like this:

class Current < ActiveSupport::CurrentAttributes
  attribute :foo
  attribute :bar
  attribute :baz
  attribute :hoge
end

You can just delete it and enjoy the benefits of SuperCurrent! Test coverage might go up, too!
