ViewFu Misc Helpers

paging(@array) #=> display a will_paginate paging links (only if the array is a valid paging collection) paging(@array, :sabros) #=> wrap the paging links with a class “sabros”

Haml Specific Helpers

Haml allows you to pash a hash of attributes. ViewFu assists this by providing a simple “hidden” helper that allows you to conditionally hide page elements.

%divhidden #=> <div style=“display:none”> %div.postshidden_if(@postshidden_if(@posts.empty?) #=> hide the .posts div if the array is empty %p.emptyhidden_unless(@postshidden_unless(@posts.empty?) #=> hide the empty posts message if the array has elements
