How to paginate blog posts in a Rails application

Question

I tried the following code but it doesn't work

class BlogsController < ApplicationController
  def index
    #@entry_pages = Paginator.new(self, Entry.count, 10, params[:page])
    @entries = Entry.find(:all,
    #:limit => @entry_pages.items_per_page,
    #:offset => @entry_pages.current.offset,
    :order => 'entries.created_at DESC',
    :include => :user)
  end
end

This is the blog view

<h1>Recently updated blogs</h1>
<% @entries.each do |entry| %>
<p>
<%= link_to entry.user.username, entries_url(:user_id => entry.user) %><br />
'<%= entry.title %>' was posted <%= time_ago_in_words(entry.created_at) %> ago
</p>
<% end %>

I want the items to be paginated like this:

<<  [1][2][3]  >>

Answer 1

Give the will_paginate GEM a try. It provides all the features you need to paginate your blog entries.

Answer 2

I can recommend the paginating_find plugin. Here's a tutorial:

Looks like it's now hosted on github.com:
