+  #
+  # If you're using Rails 2, then this error will automatically get handled like

+  #
+  # If you don't like this, use your preffered method of rescuing exceptions in
+  # public from your controllers to handle this differently. The +rescue_from+
+  # method is a nice addition to Rails 2.
+  #
+  # This error is *not* raised when a page further than the last page is
+  # requested. Use <tt>WillPaginate::Collection#out_of_bounds?</tt> method to
+  # check for those cases and manually deal with them as you see fit.
+  class InvalidPage < ArgumentError

+  # = The key to pagination
+  # Arrays returned from paginating finds are, in fact, instances of this little
+  # class. You may think of WillPaginate::Collection as an ordinary array with
+  # some extra properties. Those properties are used by view helpers to generate
+  # correct page links.
+  #
+  # WillPaginate::Collection also assists in rolling out your own pagination
+  # solutions: see +create+.
+  # 
+  # If you are writing a library that provides a collection which you would like
+  # to conform to this API, you don't have to copy these methods over; simply
+  # make your plugin/gem dependant on the "mislav-will_paginate" gem:
+  #
+  #   gem 'mislav-will_paginate'
+  #   require 'will_paginate/collection'
+  #   
+  #   # WillPaginate::Collection is now available for use
+  class Collection < Array
+    attr_reader :current_page, :per_page, :total_entries, :total_pages
+
+    # Arguments to the constructor are the current page number, per-page limit
+    # and the total number of entries. The last argument is optional because it
+    # is best to do lazy counting; in other words, count *conditionally* after
+    # populating the collection using the +replace+ method.
+    def initialize(page, per_page, total = nil)
+      @current_page = page.to_i
+      raise InvalidPage.new(page, @current_page) if @current_page < 1
+      @per_page = per_page.to_i
+      raise ArgumentError, "`per_page` setting cannot be less than 1 (#{@per_page} given)" if @per_page < 1
+      
+      self.total_entries = total if total
+    end
+
+    # Just like +new+, but yields the object after instantiation and returns it
+    # afterwards. This is very useful for manual pagination:
+    #
+    #   @entries = WillPaginate::Collection.create(1, 10) do |pager|
+    #     result = Post.find(:all, :limit => pager.per_page, :offset => pager.offset)
+    #     # inject the result array into the paginated collection:
+    #     pager.replace(result)
+    #
+    #     unless pager.total_entries
+    #       # the pager didn't manage to guess the total count, do it manually
+    #       pager.total_entries = Post.count
+    #     end
+    #   end
+    #
+    # The possibilities with this are endless. For another example, here is how
+    # WillPaginate used to define pagination for Array instances:
+    #
+    #   Array.class_eval do
+    #     def paginate(page = 1, per_page = 15)
+    #       WillPaginate::Collection.create(page, per_page, size) do |pager|
+    #         pager.replace self[pager.offset, pager.per_page].to_a
+    #       end
+    #     end
+    #   end
+    #
+    # The Array#paginate API has since then changed, but this still serves as a
+    # fine example of WillPaginate::Collection usage.
+    def self.create(page, per_page, total = nil)
+      pager = new(page, per_page, total)
+      yield pager
+      pager
+    end
+
+    # Helper method that is true when someone tries to fetch a page with a
+    # larger number than the last page. Can be used in combination with flashes
+    # and redirecting.
+    def out_of_bounds?
+      current_page > total_pages
+    end
+
+    # Current offset of the paginated collection. If we're on the first page,
+    # it is always 0. If we're on the 2nd page and there are 30 entries per page,
+    # the offset is 30. This property is useful if you want to render ordinals
+    # side by side with records in the view: simply start with offset + 1.
+    def offset
+      (current_page - 1) * per_page
+    end
+
+    # current_page - 1 or nil if there is no previous page
+    def previous_page
+      current_page > 1 ? (current_page - 1) : nil
+    end
+
+    # current_page + 1 or nil if there is no next page
+    def next_page
+      current_page < total_pages ? (current_page + 1) : nil
+    end
+    
+    # sets the <tt>total_entries</tt> property and calculates <tt>total_pages</tt>
+    def total_entries=(number)
+      @total_entries = number.to_i
+      @total_pages   = (@total_entries / per_page.to_f).ceil
+    end
+
+    # This is a magic wrapper for the original Array#replace method. It serves
+    # for populating the paginated collection after initialization.
+    #
+    # Why magic? Because it tries to guess the total number of entries judging
+    # by the size of given array. If it is shorter than +per_page+ limit, then we
+    # know we're on the last page. This trick is very useful for avoiding
+    # unnecessary hits to the database to do the counting after we fetched the
+    # data for the current page.
+    #
+    # However, after using +replace+ you should always test the value of
+    # +total_entries+ and set it to a proper value if it's +nil+. See the example
+    # in +create+.
+    def replace(array)
+      result = super
+      
+      # The collection is shorter then page limit? Rejoice, because
+      # then we know that we are on the last page!
+      if total_entries.nil? and length < per_page and (current_page == 1 or length > 0)
+        self.total_entries = offset + length
+      end

+    # = Paginating finders for ActiveRecord models
+    # 
+    # WillPaginate adds +paginate+, +per_page+ and other methods to
+    # ActiveRecord::Base class methods and associations. It also hooks into
+    # +method_missing+ to intercept pagination calls to dynamic finders such as
+    # +paginate_by_user_id+ and translate them to ordinary finders
+    # (+find_all_by_user_id+ in this case).
+    # 
+    # In short, paginating finders are equivalent to ActiveRecord finders; the
+    # only difference is that we start with "paginate" instead of "find" and
+    # that <tt>:page</tt> is required parameter:
+    #
+    #   @posts = Post.paginate :all, :page => params[:page], :order => 'created_at DESC'
+    # 
+    # In paginating finders, "all" is implicit. There is no sense in paginating
+    # a single record, right? So, you can drop the <tt>:all</tt> argument:
+    # 
+    #   Post.paginate(...)              =>  Post.find :all
+    #   Post.paginate_all_by_something  =>  Post.find_all_by_something
+    #   Post.paginate_by_something      =>  Post.find_all_by_something
+    #
+    # == The importance of the <tt>:order</tt> parameter
+    #
+    # In ActiveRecord finders, <tt>:order</tt> parameter specifies columns for
+    # the <tt>ORDER BY</tt> clause in SQL. It is important to have it, since
+    # pagination only makes sense with ordered sets. Without the <tt>ORDER
+    # BY</tt> clause, databases aren't required to do consistent ordering when
+    # performing <tt>SELECT</tt> queries; this is especially true for
+    # PostgreSQL.
+    #
+    # Therefore, make sure you are doing ordering on a column that makes the
+    # most sense in the current context. Make that obvious to the user, also.
+    # For perfomance reasons you will also want to add an index to that column.
+    module ClassMethods
+      # This is the main paginating finder.
+      #
+      # == Special parameters for paginating finders
+      # * <tt>:page</tt> -- REQUIRED, but defaults to 1 if false or nil
+      # * <tt>:per_page</tt> -- defaults to <tt>CurrentModel.per_page</tt> (which is 30 if not overridden)
+      # * <tt>:total_entries</tt> -- use only if you manually count total entries
+      # * <tt>:count</tt> -- additional options that are passed on to +count+
+      # * <tt>:finder</tt> -- name of the ActiveRecord finder used (default: "find")

+  module NamedScope
+    # All subclasses of ActiveRecord::Base have two named_scopes:
+    # * <tt>all</tt>, which is similar to a <tt>find(:all)</tt> query, and
+    # * <tt>scoped</tt>, which allows for the creation of anonymous scopes, on the fly: <tt>Shirt.scoped(:conditions => {:color => 'red'}).scoped(:include => :washing_instructions)</tt>
+    #
+    # These anonymous scopes tend to be useful when procedurally generating complex queries, where passing
+    # intermediate values (scopes) around as first-class objects is convenient.
+    def self.included(base)
+      base.class_eval do
+        extend ClassMethods
+        named_scope :scoped, lambda { |scope| scope }

+
+    module ClassMethods
+      def scopes
+        read_inheritable_attribute(:scopes) || write_inheritable_attribute(:scopes, {})
+      end
+
+      # Adds a class method for retrieving and querying objects. A scope represents a narrowing of a database query,
+      # such as <tt>:conditions => {:color => :red}, :select => 'shirts.*', :include => :washing_instructions</tt>.
+      #
+      #   class Shirt < ActiveRecord::Base
+      #     named_scope :red, :conditions => {:color => 'red'}
+      #     named_scope :dry_clean_only, :joins => :washing_instructions, :conditions => ['washing_instructions.dry_clean_only = ?', true]
+      #   end
+      # 
+      # The above calls to <tt>named_scope</tt> define class methods <tt>Shirt.red</tt> and <tt>Shirt.dry_clean_only</tt>. <tt>Shirt.red</tt>, 
+      # in effect, represents the query <tt>Shirt.find(:all, :conditions => {:color => 'red'})</tt>.
+      #
+      # Unlike Shirt.find(...), however, the object returned by <tt>Shirt.red</tt> is not an Array; it resembles the association object
+      # constructed by a <tt>has_many</tt> declaration. For instance, you can invoke <tt>Shirt.red.find(:first)</tt>, <tt>Shirt.red.count</tt>,
+      # <tt>Shirt.red.find(:all, :conditions => {:size => 'small'})</tt>. Also, just
+      # as with the association objects, name scopes acts like an Array, implementing Enumerable; <tt>Shirt.red.each(&block)</tt>,
+      # <tt>Shirt.red.first</tt>, and <tt>Shirt.red.inject(memo, &block)</tt> all behave as if Shirt.red really were an Array.
+      #
+      # These named scopes are composable. For instance, <tt>Shirt.red.dry_clean_only</tt> will produce all shirts that are both red and dry clean only.
+      # Nested finds and calculations also work with these compositions: <tt>Shirt.red.dry_clean_only.count</tt> returns the number of garments
+      # for which these criteria obtain. Similarly with <tt>Shirt.red.dry_clean_only.average(:thread_count)</tt>.
+      #
+      # All scopes are available as class methods on the ActiveRecord::Base descendent upon which the scopes were defined. But they are also available to
+      # <tt>has_many</tt> associations. If,
+      #
+      #   class Person < ActiveRecord::Base
+      #     has_many :shirts
+      #   end
+      #
+      # then <tt>elton.shirts.red.dry_clean_only</tt> will return all of Elton's red, dry clean
+      # only shirts.
+      #
+      # Named scopes can also be procedural.
+      #
+      #   class Shirt < ActiveRecord::Base
+      #     named_scope :colored, lambda { |color|
+      #       { :conditions => { :color => color } }
+      #     }
+      #   end
+      #
+      # In this example, <tt>Shirt.colored('puce')</tt> finds all puce shirts.
+      #
+      # Named scopes can also have extensions, just as with <tt>has_many</tt> declarations:
+      #
+      #   class Shirt < ActiveRecord::Base
+      #     named_scope :red, :conditions => {:color => 'red'} do

+      #       end
+      #     end
+      #   end
+      #

+    # * <tt>:page_links</tt> -- when false, only previous/next links are rendered (default: true)
+    # * <tt>:inner_window</tt> -- how many links are shown around the current page (default: 4)
+    # * <tt>:outer_window</tt> -- how many links are around the first and the last page (default: 1)
+    # * <tt>:separator</tt> -- string separator for page HTML elements (default: single space)
+    # 
+    # HTML options:
+    # * <tt>:class</tt> -- CSS class name for the generated DIV (default: "pagination")
+    # * <tt>:container</tt> -- toggles rendering of the DIV container for pagination links, set to
+    #   false only when you are rendering your own pagination markup (default: true)
+    # * <tt>:id</tt> -- HTML ID for the container (default: nil). Pass +true+ to have the ID
+    #   automatically generated from the class name of objects in collection: for example, paginating
+    #   ArticleComment models would yield an ID of "article_comments_pagination".
+    #
+    # Advanced options:
+    # * <tt>:param_name</tt> -- parameter name for page number in URLs (default: <tt>:page</tt>)
+    # * <tt>:params</tt> -- additional parameters when generating pagination links
+    #   (eg. <tt>:controller => "foo", :action => nil</tt>)
+    # * <tt>:renderer</tt> -- class name, class or instance of a link renderer (default:
+    #   <tt>WillPaginate::LinkRenderer</tt>)
+    #
+    # All options not recognized by will_paginate will become HTML attributes on the container

+    # ==== Using the helper without arguments
+    # If the helper is called without passing in the collection object, it will
+    # try to read from the instance variable inferred by the controller name.
+    # For example, calling +will_paginate+ while the current controller is
+    # PostsController will result in trying to read from the <tt>@posts</tt>
+    # variable. Example:
+    #
+    #   <%= will_paginate :id => true %>
