Rails Theme Support Plugin v 1.4

I've just checked in version 1.4 of the theme_support plugin. It contains quite a few bugfixes and updates. This version also integrates a couple of patches from akg and D.J. Vogel. Thanks guys!

Version 1.4 adds:

  • Bugfixes, of course
  • Better Rails 1.1 support
  • ActionMailer theme support (experimental)
  • Updates to the themeitem liquid tag
  • Support for theme sub-directories
  • Fleshed out the Theme object to make is easy to list all of the installed Themes

As a little background, the plugin is based on the theme system developed by the Typo guys and adds support for:

  • Multiple concurrent themes
  • A rails generator for creating a theme folder structure
  • Rake tasks for pre-caching all of the themes for increased security and performance
  • Overriding views with theme-specific rhtml or liquid templates (based on early Typo code)
  • Forcing theme views to only allow liquid templates
  • Made supporting themes as easy as using layouts

To install the plugin, go to your rails application root folder and run:

  ./script/plugin install

or, for you Windows folks:

  ruby script\\plugin install

Look at the README in $/vendor/plugins/theme_support for more on implementing themes in your application.

More Zebras

Update: OK, you got me. You should really use the built-in Rails helper, cycle.

<table class="Grid">
 <% for user in @users %>
  <tr class="<%= cycle('Even', 'Odd') %>">
      ... Stuff Here
 <% end %>
Here's the helper I've been using lately for zebra striping table rows:
def zebra_stripe( index, even_class="Even", odd_class="Odd" )
  index % 2 == 0 ? even_class : odd_class
In the view, you use the rubyesque .each_with_index like this:
<table class="Grid">
<% @users.each_with_index do |user, i| %>
  <tr class="<%= zebra_stripe(i) %>">
      ... Stuff Here
<% end %>
Simple as that!
