It's true that will_paginate in datamapper will fire off the request to the database as soon as you send it the paginate command. So it doesn't play nice with datamapper's lazy loading techniques.
However, Datamapper is pretty flexible, so it's very easy to workaround in your view. For example, instead of running the paginate in your controller, you can just run the paginate command in the view in place of your kicker (each). It may get a little messy, since you need to assign the result to a variable, but with the right view helper wrapper, it can get much cleaner. # in controller (no queries will be run yet) @posts = @category.posts.active.latest # in view - posts = @posts.paginate(:page => params[:page]) - for post in posts = render_post(post) = will_paginate(posts) # with helper: http://gist.github.com/64912 = paginate(@posts) do |post| = render_post(post) On Feb 14, 9:55 am, Jon Hancock <[email protected]> wrote: > I am still using paginator although I have heard several > recommendations to go with the leading will_paginate agnostic. > The reason I did not switch is all the examples I see indicate it does > not work well with datamapper "style". datamapper exposes a chained > style of querying such as "this_user.posts.draft_status".
