The new paginate squirrel method takes a hash with :page (1-indexed) and :per_page (which default to 1 and 20, respectively). When you use it, your results array is automatically extended with a helpful pages method that gives you all you need to know to paginate your views. It also puts a total_results method on there, so you know how big the whole search is.

And before you ask, yes, I know some of you asked for this to work with paginating_find, and it does. But we found that paginating_find was conflicting with other plugins, leading to some really weird errors. Plus, it’d always been my intention to add pagination (among other things) anyway.

Please Note: The repo has changed. It’s now at https://svn.thoughtbot.com/plugins/squirrel/trunk for the trunk and https://svn.thoughtbot.com/plugins/squirrel/tags/rel-1.0.0 for this release.
