Allows you to set default values when setting attributes using attr_accessor or attr_reader. Saves having to define attributes then instantly override them to set a default method.
Turns this:
class Foo
attr_accessor :things
def things
@things ||= []
end
end
into this:
class Foo
attr_accessor :things, default: []
end
Also works with attr_accessor or attr_reader in modules, and with passing multiple attributes to define at once.
Add this line to your application's Gemfile:
gem 'defaultinator'
And then execute:
$ bundle
Or install it yourself as:
$ gem install defaultinator
If you're not setting default values for the attribute, then just use attr_accessor (or attr_reader) as normal including setting multiple attributes at once.
attr_accessor :foo
attr_accessor :sed, :fred
attr_reader :bar
attr_reader :george, :paul
If you want default values, it's much the same but just pass a hash as the last argument stating what the default value is.
attr_accessor :foo, default: true
attr_accessor :sed, :fred, default: []
attr_reader :bar, default: {}
attr_reader :george, :paul, default: false
