Dynamic hashed link in Flask

OK, so I have this code in the server side:

@app.route('/physical_graph') 
@login_required 
def physical_graph():
    # Some code
    return generate_graph_view()

If we click on the circular icon, we will get the link /physical_graph#physical.circular:

<a class="icon" href="/physical_graph#physical.circular">
    <img src="{{url_for('static',filename='images/circular64x64.png')}}" 
         id="circular_icon" width="32" height="32" title="Circular layout"/>
</a>

My question is: how can I tell Flask what string is after the hash? I need this because the code in the comment depends on this string. I tried with stating the app.route as:

@app.route('/physical_graph#<some_string>')

but without success - it gives me Error 404.

Any ideas how to do this?

When you ajaxify it you need to pass physical.circle to the server. First is just a comment on the use of icon:

<!-- notice i change from icon -> graphIcon icon is too general  -->
<!--a stylist would be angry at you for using icon -->
<a class="graphIcon" href="/physical_graph#physical.circular"> .. </a>

You have some options first would be to pass it in the data attribute, this would be placed somewhere in javascript (that only gets executed once).

jQuery("#circular_icon").click(function() {
   $.ajax({
         url:'/physical_graph', 
         data:{
               'graph_type': 'physical_graph.circular'
         },
         'success':function(data){
             //your function goes here. 
         }
   })
} );

@app.route('/physical_graph') 
@login_required 
def physical_graph():
  _type = request.args.get('graph_type')
