[Rails] Re: paginate issues

This is a great idea.
I always make mini projects to learn new functionality and then move it to my main project when I've got it working right.

I would suggest that you start a new app just to learn how to use
pagination.  RailsSpace is a good tutorial but there are several
"version of..." issues embedded in the code.  Pagination is one.

1)       "gem install mislav-will_paginate"
   (or "sudo gem install mislav-will_paginate" if you must)

NOTE: this is not the same gem as will_paginate.

2)       Go to "http://github.com/mislav/will_paginate/blob/master/
README.rdoc" and keep this page up in your browser as you follow the
instructions.

3)       run "rails pagin" and create a throw-away app that will just
do pagination.  I would suggest that you just have one model - Word -
and create a word index that paginates 10 words per page, then get
fancy and sort the words.

The simplest way to go is to have your words_controller.rb include:

require 'will_paginate'

def index
  #@words = Word.all
  @words = Word.paginate :page => :params[:page], :per_page => 10
.
.
.

And to have your index.html.erb include:

<h1>Listing words</h1>
<%= will_paginate @words %>
.
.
.

NOTE: there appears to be a bug related to the view pagination
controls under Ruby 1.9 - all's good with 1.8 however.
