I am developing a django application in which I am trying to send a value of the variable to the backend on click of a button through javascript.

javascript code:

$(document).on("click", "#filter", function (e) {
      IUPredscorethreshold = 0.4
      $("#ksNetwork").empty();
      ksInteractionNetwork('{% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id IUPredscorethreshold %}');
 });

urls.py

path(
        "dataJson/newinteractors_intnet/<str:geneId>/<str:IUPredscorethreshold>",
        views.newinteractors_intnet,
        name="newinteractors_intnet",
    ),

views.py

@csrf_exempt
def newinteractors_intnet(request, geneId, IUPredscorethreshold):

    print("IUPredscorethreshold:" + IUPredscorethreshold)

.
.
.
.
.
some computation


    graphData = {"nodes": uniquenodesdata, "links": linksdata}

    response = JsonResponse(graphData)

    return response

when I execute this code i am getting following error:

NoReverseMatch at /v2/search/SARS_CoV_2/GID1716
Reverse for 'newinteractors_intnet' with arguments '('GID1716', '')' not found. 1 pattern(s) tried: ['v2/dataJson/newinteractors_intnet/(?P<geneId>[^/]+)/(?P<IUPredscorethreshold>[^/]+)$']
Exception Value:

what am I doing wrong? how can I solve this issue. I am still at learning stage of django and I am not able to figure out how to solve this error.

Answer

The error message says it couldn’t find a url that matches {% url "camkinetv2:newinteractors_intnet" tab1.caMKipedia_Id IUPredscorethreshold %}. Your urls.py declares IUPredscorethreshold to be a string by putting str: in front of it. In your javascript you assign 0.4 to that variable which is an integer. Therefore, the url you doesn’t resolve.

Change your path in urls.py to: path( "dataJson/newinteractors_intnet/<str:geneId>/<int:IUPredscorethreshold>", views.newinteractors_intnet, name="newinteractors_intnet", ),
