Is there a pluralize function in Ruby NOT Rails?
I am开发者_JAVA百科 writing some Ruby code, not Rails, and I need to handle something like this:
found 1 match
found 2 matches
I have Rails installed so maybe I might be able to add a require
clause at the top of the script, but does anyone know of a RUBY method that pluralizes strings? Is there a class I can require that can deal with this if the script isn't Rails but I have Rails installed?
Edit: All of these answers were close but I checked off the one that got it working for me. Try this method as a helper when writing Ruby, not Rails, code:
def pluralize(number, text)
return text.pluralize if number != 1
text
end
Actually all you need to do is
require 'active_support/inflector'
and that will extend the String type.
you can then do
"MyString".pluralize
which will return
"MyStrings"
for 2.3.5 try:
require 'rubygems'
require 'active_support/inflector'
should get it, if not try
sudo gem install activesupport
and then the requires.
Inflector is overkill for most situations.
def x(n, singular, plural=nil)
if n == 1
"1 #{singular}"
elsif plural
"#{n} #{plural}"
else
"#{n} #{singular}s"
end
end
Put this in common.rb, or wherever you like your general utility functions and...
require "common"
puts x(0, 'result') # 0 results
puts x(1, 'result') # 1 result
puts x(2, 'result') # 2 results
puts x(0, 'match', 'matches') # 0 matches
puts x(1, 'match', 'matches') # 1 match
puts x(2, 'match', 'matches') # 2 matches
I personally like the linguistics gem that is definitely not rails related.
# from it's frontpage
require 'linguistics'
Linguistics.use :en
"box".en.plural #=> "boxes"
"mouse".en.plural #=> "mice"
# etc
This works for me (using ruby 2.1.1 and actionpack 3.2.17):
~$ irb
>> require 'action_view'
=> true
>> include ActionView::Helpers::TextHelper
=> Object
>> pluralize(1, 'cat')
=> "1 cat"
>> pluralize(2, 'cat')
=> "2 cats"
require 'active_support'
require 'active_support/inflector'
inf = ActiveSupport::Inflector::Inflections.new
to get the inflector, not sure how you use it
my solution:
# Custom pluralize - will return text without the number as the default pluralize.
def cpluralize(number, text)
return text.pluralize if number != 1
return text.singularize if number == 1
end
So you can have 'review' returned if you call cpluralize(1, 'reviews')
Hope that helps.
I've defined a helper function for that, I use it for every user editable model's index view :
def ovyka_counter(array, name=nil, plural=nil)
name ||= array.first.class.human_name.downcase
pluralize(array.count, name, plural)
end
then you can call it from the view :
<% ovyka_counter @posts %>
for internationalization (i18n), you may then add this to your locale YAML files :
activerecord:
models:
post: "Conversation"
