Find old official rails trunk plugins that didn't make the cut here:

http://dev.rubyonrails.org/svn/rails/plugins/legacy/

This nightmare has required the following:

Tests
- Add

ENV[‘DB’] = ‘mysql’

to /config/environment.rb
- Add:

rescue Technoweenie::AttachmentFu::Backends::S3Backend::RequiredLibraryNotFoundError

to /vendor/plugins/attachment_fu/test/fixtures
- Go into ../test and run: ruby test_helper.rb
- if all goes well you should finish the test_helper load without error.
- delete the file backends/remote/s3_test.rb (useless tests of S3 system)

Attached is a generators directory that should go under the base directory of attachment_fu/
This can be used as a model generator for models using a_fu. Use scaffold_resource generator after attachment_model to generate a skeleton site upon which to build.

Uses h_a_b_t_m relationship to Tier table (via tiers_users join table) to return an array of access groups this user is a member of.

def is_admin? #TODO: make into an accessor?
        return false unless self.tiers
        tier_names = self.tiers.collect {|t| t.name}
        return tier_names.include? "admin"
end

// description of your code here
controller layout (base) stylesheet update

  <%= stylesheet_link_tag 'scaffold', 'tag_cloud' %>

create stylesheet, put it in ./public/, name it tag_cloud.css or similar

/* tag_cloud styles*/
.nube1 {font-size: 1.0em;}
.nube2 {font-size: 1.2em;}
.nube3 {font-size: 1.4em;}
.nube4 {font-size: 1.6em;}
.nube5 {font-size: 1.8em;}
.nube6 {font-size: 2.0em;}

partial template call

        TAG CLOUD<br/>
        <%= render(:partial => "shared/article_tag_cloud", :locals => {:tags => @tags}) %>

view template code, as a partial or within index/show action template

        <% # For our purposes, have this filter the list of articles to those with the chosen tag
                tag_cloud true, tags, %w(nube1 nube2 nube3 nube4 nube5) do |name, css_class| %>
                <%= link_to name, tag_path(name), class => css_class # links to Tag resource, with tag name as 'id'
                %>
        <% end %>

helper code

        def tag_cloud(active, tags, classes)
                if !active then return end
                max, min = 0, 0
                unless tags.empty?
                        tags.sort! {|x,y| y.count <=> x.count}
                        max = tags.first.count
                        min = tags.last.count                      
                end
        
                divisor = ((max - min) / classes.size) + 1
        
                tags.each { |t|
                        yield t.name, classes[(t.count.to_i - min) / divisor]
                }
        end
