how can i link to a tag using tag_counts from acts_as_taggable?

I am using acts_as_taggable to add tags to a post in order to be able to show all posts with the specific tag. This worked fine for me with:

  #in posts_controller.rb
def index
if params[:tag].present?
  @posts = Post.tagged_with(params[:tag]).paginate(:page => params[:page])
else
  @posts = Post.all.order("created_at DESC")
end
end

and displaying them in my index.html.erb with

<p> tags: <%= raw post.tags.map{ |t| link_to t.name, posts_path(tag: t.name)}.join(', ')  %><p>

Now i want to display all tags in another view with <%=raw Post.tag_counts_on(:tags).map{|t| link_to t.name, posts_path(tag: t.name)}%>

and faced the problem that t.name is no longer just the tag name but "/t.name\" which is linking me to the wrong site.

Is there a way to solve this problem or maybe even a better solution to link all tags that i got?
