Rails.cache and problem with model id?

Rails
1

I have the following:
MODEL:

def self.get_tag_cloud
Rails.cache.fetch(‘fetish_tag_cloud’, :expires_in => 1.hour) do
find(:all, :conditions => [ “approved_for_tag_cloud = true”],
:order
=> “LTRIM(name)”)
end
end

CONTROLLER:

def index
@fetishes = Fetish.get_tag_cloud
end

VIEW:

…
<% @fetishes.each do |fetish| -%>

  • <%= link_to fetish.name, "/fetishes/#{fetish.id}", :class => "size#{fetish.tag_size}"%>
    • <% end -%> ....

    I get the following error:

    stack level too deep

    /Library/Ruby/Gems/1.8/gems/activerecord-2.1.2/lib/active_record/attribute_methods.rb:244:in
    method_missing' /Library/Ruby/Gems/1.8/gems/activerecord-2.1.2/lib/active_record/attribute_methods.rb:245:in method_missing’
    /Library/Ruby/Gems/1.8/gems/activerecord-2.1.2/lib/active_record/base.rb:2163:in
    to_param' (eval):2:in fetish_path’
    app/views/fetishes/index.html.erb:22:in
    _run_erb_47app47views47fetishes47index46html46erb' app/views/fetishes/index.html.erb:21:in each’
    app/views/fetishes/index.html.erb:21:in
    `_run_erb_47app47views47fetishes47index46html46erb’

    If I do not cache the query it works beautifully… basically when I
    cache
    that query anytime I try to view fetish.id I get a stack level to deep
    error… anyone ever get this problem?

    More info… the first time when I write to the cache it works
    perfectly fine… the second time around when I am reading from the
    cache the errors start popping up. hmmm…
