Problems with Rails 3 tags, actions_as_taggable_on

Question

I use act_as_taggable_on to add tags to posts, other plugins / gems with tags do not work with rails. 3. I can edit / display tags in the message model, and the tag controller displays messages marked with the name ie / tags / tag name-post /. I want to use tags on message pages in links to display other posts with the same tag. I followed a tutorial on "just rails 2" sites that uses act_as_taggable_on_steroids, but I was stuck with the following error:

ActionView::MissingTemplate in Posts#show Missing partial acts_as_taggable_on/tags/tag with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths "../app/views" Extracted source (around line #28): 25: <div id="tags"> 26: <% unless @post.tag_list.empty? %> 27: <p class="tags"> 28: <%= render :partial => @post.tags %></p> 29: <% end %> 

...

 class Post < ActiveRecord::Base ... acts_as_taggable_on :tags end class TagsController < ApplicationController def show @post = Post.tagged_with(params[:id]) end end 

_tag.html.erb

 <%= link_to, tag_path(:id => tag.name) %> 

posts / show.html.erb

 <div id="tags"> <% unless @post.tag_list.empty? %> <p class="tags"> <%= render :partial => @post.tags %></p> <% end %> </div> 

Also trying to add a tag cloud in the /index.html tags, as described here http://github.com/mbleigh/acts-as-taggable-on gives me a routing error;

 No route matches {:action=>"tag", :id=>"news", :controller=>"tags"} 

Answer 1

It looks like you want to use: collection, which will display the entire list using a template:

 <div id="tags"> <% unless @post.tag_list.empty? %> <p class="tags"> <%= render :partial => 'tag', :collection => @post.tags %> </p> <% end %> </div>
