I was working through the simply rails book, i have completed up to  
chapter 10,  
now i want to add tag clouds to the welcome page ? how to do it ?

I have installed acts\_as\_taggable\_on\_steroids plugin from here  
[http://svn.viney.net.nz/things/rails/plugins/acts\_as\_taggable\_on\_steroids](http://svn.viney.net.nz/things/rails/plugins/acts_as_taggable_on_steroids)

I was going through their readme file as per the readme file i did the  
following changes

1. in app/helpers/application\_helper.rb file

module ApplicationHelper

```
include TagsHelper

```

end

1. class StoriesController \< ApplicationController

2. in app/views/stories/index.html.erb file i have added

\<% 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 %\>

1. in /public/stylesheets/style.css

i have added

.css1 { font-size: 1.0em; }

.css2 { font-size: 1.2em; }

.css3 { font-size: 1.4em; }

.css4 { font-size: 1.6em; }

after doing all these when i access [http://0.0.0.0:3000/stories/](http://0.0.0.0:3000/stories/)

i am getting the error message as

undefined method `tag\_cloud’ for #ActionView::Base:0xb5879a78

You are trying to use a controller method like a helped method. Try  
moving the method to applicationhelper and seeing if that works

you mean moving

def tag\_cloud

@tags = Story.tag\_counts

end

to app/helpers/application\_helper.rb

Your method accepts no argument. Try something like:

def tag\_cloud(args\*)

I don’t remember if this is the correct syntax. Search for  
it. 🙂
