Sorry but I'm a little confused now on what's happening in your app. Please
answer the following questions:
1. is your view for the index and tag actions the same?
2. since you are now using params[:id] instead of params[:name], are you
getting the right posts?
3. please post the corresponding routes line that matches
/posts/tag/tag_name
