How can I create a helper that will take tags and put into links in Rails 3?

I am using acts_as_taggable_on, and everytime I want to display tags, I use the following:

  7     #tags
  8       %label Tags:
  9       - @vendor.tags.each do |tag|
 10         = link_to tag.name, tag_path(tag.name)

I have different models that all have tags, so ideally it would be a single helper that I pass the resource to...thinking something to do with using content_tag and a block....?

You can create a helper to display tags.

#tag_helper.rb
def display_tags(tags)
  tag_string = ""
  tags.each do |tag|
    tag_string << link_to tag.name, tag_path(tag.name)
  end
  tag_string.html_safe
end

#view.html.erb
=display_tags(@vendor.tags)
