I am looking to use ActionView::Helpers::NumberHelper from a Ruby script. What all do I need to require etc.?
~> irb
ruby-1.9.2-p180 :001 > require 'action_view'
=> true
ruby-1.9.2-p180 :002 > ActionView::Base.new.number_to_currency 43
=> "$43.00"
As of Rails 3.2.13, you can do the following:
class MyClass
include ActionView::Helpers::NumberHelper
def my_method
...
number_with_precision(number, precision: 2)
...
end
end
You might need to require 'action_view'
too.
Edit: This answer is still valid in Rails 4.2.3.
