Pluralize Without Count

Helper method that returns the word without the count.

application_helper.rb

def pluralize_without_count(count, noun, text = nil)
  if count != 0
    count == 1 ? "#{noun}#{text}" : "#{noun.pluralize}#{text}"
  end
end

Example usage:

_form.html.erb

<%= pluralize_without_count(item.categories.count, 'Category', ':') %>

Hour with/without preceding zero

One gotcha is the difference between the hour in 12 hour time with and without a preceding zero. In some fonts they look the same.

With preceding zero (capital I)

Time.now.strftime("%I:%M") # => 05:21

Without preceding zero (lowercase L)

Time.now.strftime("%l:%M") # => 5:21
