Converting all ERb views to Haml

divoxx (Rodrigo Kochenburger) — Thu, 01 May 2008 23:27:09 GMT

A little script to convert all your .erb views to .haml using html2haml, which is included with Haml installation.
Just drop this in your rails root folder and run it.



class ToHaml

  def initialize(path)

    @path = path

  end

  

  def convert!

    Dir["#{@path}/**/*.erb"].each do |file|

      `html2haml -rx #{file} #{file.gsub(/\.erb$/, '.haml')}`

    end

  end

end



path = File.join(File.dirname(__FILE__), 'app', 'views')

ToHaml.new(path).convert!

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 %>

My default layout in Rails projects

peter (Peter Cooperx) — Wed, 15 Feb 2006 01:40:24 GMT

Writing a new layout from scratch gets boring, so I have a generic / default layout to use and extend from.









	

	<%= @page_title %>

	<%= stylesheet_link_tag "main" %>

	<%= javascript_include_tag "prototype" %>

	<%= javascript_include_tag "scriptaculous" %>

	<%= javascript_include_tag "general" %>

	







	

			

	<%= @content_for_layout %>
