Issues with acts_as_taggable plugin

Rails
1

Not the gem.

I’ve got something working in console, but not in controller. Any idea
why?

This is the plugin not the gem of acts_as_taggable

View

Listing elements

<% if @elements.blank? %>

There are currently no elements in the system tagged <%=
“"#{params[:tag_name]}"” %>.


<% else %>

Currently tracking <%= @elements.size %> elements in the system
tagged <%= “"#{params[:tag_name]}"” %>.

	<%= render :partial => 'element', :collection => @elements %>

<% end %>

<%= link_to ‘New element’, new_element_path %>

This returns that the array is empty and there’s nothing in the tag in
http://localhost:3000/elements/tagged/:tag_name

SO teh view is seeing it, but the controller is not getting it. Because
in the console, using a string in place of params(:tag_name) returns an
actual entry.

Controller

def tagged # This should take the :tag_name in the url string and pull elements that match # It does not. I suck as a programmer. @elements = Element.find_tagged_with(params[:tag_name]) 
respond_to do |format|
  format.html # index.rhtml
  format.xml  { render :xml => @elements.to_xml }
end

end

Models

class Element < ActiveRecord::Base

acts_as_taggable
[…]
end

CONSOLE

This does work:

Loading development environment.

@elements = Element.find_tagged_with(“spam”)

But this does not (because there is no value in params[:tag_list]:
