Since I stole everything else, I figured I’d duplicate the donation link as well.

Tag Cloud

module ApplicationHelper
  include TagsHelper
end

Here is an example that generates a tag cloud.

class PostController < ApplicationController
  def tag_cloud
    @tags = Post.tag_counts
  end
end

<% tag_cloud @tags, %w(css1 css2 css3 css4) do |tag, css_class| %>
  <%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %>
<% end %>

Caching

It is useful to cache the list of tags to reduce the number of queries executed. To do this, add a column named cached_tag_list to the model which is being tagged. The column should be long enough to hold the full tag list and must have a default value of null, not an empty string.

Call save_cached_tag_list manually to update the cache!

  TagList.delimiter = " "    # use spaces instead of commas
  Tag.destroy_unused = true  # automatically remove dead tags
