Rails请求引荐来源网址不包含#xxx

Question

I have a Rails 3 form where I'm using Bootstrap tabs. Each tab renders a different form (but to the same controller).

When I submit the form on tab2, the URL at the top of the page is:

http://localhost:3000/costprojects/1#tab2

In the costprojects controller, I want to go to the next tab when the user submits a form.

I thought this would work:

  def update
    @costproject = Costproject.find(params[:id])
    nextpath =  costproject_path(@costproject) + '#tab2'
    nextpath =  costproject_path(@costproject) + '#tab3' if request.referer.include?("#tab2")
    nextpath =  costproject_path(@costproject) + '#tab4' if request.referer.include?("#tab3")


    respond_to do |format|
      if @costproject.update_attributes(params[:costproject])
        format.html { redirect_to nextpath, notice: 'Capital Project was successfully updated.' } 

But, the request.referer doesn't include the 'tab2'.

How come?

Thanks for the help!

The anchor is only available client side. It's never sent as part of any request header. See Is the anchor part of a URL being sent to a web server?
