You need to iterate through all the posts tagged with params[:name] so do the following
in the controller method, use @posts = Post.tagged_with(params[:name]) #note that it's plural and in tag.html.erb, instead of using @post, use @posts but iterate through each post <% @posts.each do |post| %> <%= post.title %> <% end %> > but Rails insists in fetching the id as parameter. > > Any idea? > Thanks guys! > > -- > Posted via http://www.ruby-forum.com/. > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk@googlegroups.com. > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > > -- ------------------------------------------------------------- visit my blog at http://jimlabs.heroku.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
