Block to Partial Rails Helper

err (Chris Wanstrath) — Mon, 28 Aug 2006 05:49:13 GMT

From http://errtheblog.com/post/13.
Create a helper which takes a block and renders that block within the context of a partial.

Create this helper:



def block_to_partial(partial_name, options = {}, &block)

  options.merge!(:body => capture(&block))

  concat(render(:partial => partial_name, :locals => options), block.binding)

end

Create this helper, too:



def sidebar_module(title, options = {}, &block)

  block_to_partial('shared/sidebar_module', options.merge(:title => title), &block)

end

Create this partial (app/views/shared/_sidebar_module.rhtml):



 class="sidebar_module">

  <%= title %>

  <%= body %>

Use it in your views:



<% sidebar_module 'Recent Stories' do %>

  <%= render :partial => 'recent_stories', :collection => @recent_stories %>

<% end %>
