will_paginate i18n keys

readme.md

Variations of output:

1. No users found
2. Displaying 1 user
3. Displaying all 27 users
4. Displaying users 12 - 18 of 27 in total

The problem is, "user/users" is a variable name since this view helpers accepts collections of any kind of objects. So I've really got 2 dimensions for i18n:

1. translation for the name of the object ("User" in this case) and its plural form
2. translation of view helper output outlined above.

Below are translations that handle scenario 2), but I have no inspiration about 1).

translate

module SomeGoodPlaceInWillPaginate
  def translate(key, options = {})
    # I've just copied these :cascade options from http://svenfuchs.com/2011/2/11/organizing-translations-with-i18n-cascade-and-i18n-missingtranslations
    # I don't think they actually work exactly like this, but i'm too tired right now :) Would need to look up in I18n::Backend::Cascade.
    #
    # super would call the ActionView#translate helper here
    super(key, options.merge(:cascade => { :offset => 2, :skip_root => false }))
  end
  alias t translate
end

# somewhere else ...

scope = :'views.will_paginate'
key = resource.class.name.underscore
default = ... # not sure. there's now Model.human_name. not sure it accepts a :count in Rails 2.3.x already.
model = t(key, :count => count, :default => default, :scope => [scope, :models])
t(:page_entries_info, :count => count, :model => model, :scope => scope)

# any controller/action, with resource == User, count == 0
"No users found"

# on very_special_things/index, count == 0
"No thingongs found"
