Ahoy, having a bit of difficulty w/ the acts as taggable GEM.  
I was able to create a tagcloud, but now i want to filter items by tags.

in my controller i have

def show\_tagged\_with  
\<-- snip snip --\>  
@items = Item.find\_tagged\_with( :any =\> params[:tag\_name])  
@categories = Category.find\_all  
@tag\_name = params[:tag\_name]  
@tagged\_items = Item.tags\_count(:limit =\> 100)  
end

IN the VIEW  
\<% @items.each do |item| %\>  
\<%= render :partial =\> ‘list\_stripes’, :locals =\> { :item =\> item } %\>  
\<% end %\>

Where the partial \_list\_stripes.rthml is a list of items

```
<td><%=h item.tag_names.join(" ") %></td>
<td><%=h item.created_on %></td>
<td><%=h item.category.name %></td>

```

But i get an error

“undefined method `tag\_names’ for #Array:0x3673b08”

any ideas?

Example of what works. Convert for your needs.

in tags\_controller.rb

def info  
@name = params[:name]  
@tag = Tag.find(:first, :conditions =\> “name = ‘#{@name}’”)  
end

in info.rhtml  
\<% for @item in @tag.tagged %\>  
\<%= render :partial =\> “render\_item” %\>  
\<% end %\>

in the partial \_render\_item.rhtml  
  
\<%= @ item.name -%\>  
  
\<%= @ item.description -%\>
