will_paginate

will_paginate v2.3 is a pagination plugin for Rails and Active Record.

Installation:

## environment.rb
Rails::Initializer.run do |config|
  config.gem 'will_paginate', :version => '~> 2.3.16'
end

See installation instructions on the wiki for more info.

Basic will_paginate use

## perform a paginated query:
@posts = Post.paginate(:page => params[:page])

# or, use an explicit "per page" limit:
Post.paginate(:page => params[:page], :per_page => 30)

## render page links in the view:
<%= will_paginate @posts %>

And that's it! You're done. You just need to add some CSS styles to make those pagination links prettier.

You can customize the default "per_page" value:

# for the Post model
class Post
  self.per_page = 10
end

# set per_page globally
WillPaginate.per_page = 10

See the wiki for more documentation. Ask on the group if you have usage questions. Report bugs on GitHub.

Happy paginating.
