NoReverseMatch at /add/

I keep getting error on my url tag. The syntax is right and i tried different solution that is asked on SO but no luck yet.

my urls.py 

urlpatterns = [
    url(r'^$', LandingView.as_view(), name="landing_page"),
    url(r'^add/$', AddView.as_view(), name="add"),
    url(r'^rent/(?P<slug>\w+)/$', rent_detail, name="rent_detail"),
    url(r'^add/space/$', AddSpaceView.as_view(), name="addSpace"),
    url(r'^lang/$', Language.as_view(), name="lang"),
    url(r'^upload/image/(?P<pk>\d+)/$', ImageUpload, name="ImageUpload"),
    url(r'^filter/space/$', FilterSpace.as_view(), name="filterSpace"),
    url(r'^api/', include(v1_api.urls)),
]

views.py

def ImageUpload(self, request, *args, **kwargs):
    try:
        rental = Rental.objects.get(pk = kwargs.get('pk'))
    except Rental.DoesNotExist:
        error_dict = {'message': 'Rental spae not found'}
        return self.render(request,'rentals/add.html',error_dict)
    for file in request.FILES.getlist('image'):
        image = GalleryImage.objects.create(image=file,rental=rental)
    response_dict = {
        'message': 'File Uploaded Successfully'
    }
    context = {
        'rental':rental
    }
    return self.render(request,'rentals/add.html',context)

class AddView(TemplateView):
    template_name = 'rentals/add.html'

add.html

<div id="listing">
</div>
<script type="text/javascript">
  // want to passs url for uploading image in ajax url parameter
    var data = {
        urltag: "{% url 'ImageUpload' rental.id %}"
    }

    console.log('url is', data); 
    $(function() {
      app.showListingSpaceForm("listing",data);
    });

</script>

ajax for uploading image

 $.ajax({
        url:"/upload/image/", // upload form is in add.html which is developed using frontend library reactjs and i need to pass id here so that the image will be saved to its associated rent.
        data:image,
        contentType:false,
        processData:false,
        type:'POST',
        mimeType: "multipart/form-data",
        success: function(data) {
          console.log('success');
        }
       });
    }

Update: Ajax code where i want id in url for uploading image to its associated rent

When you go to /add/, Django will run AddView because you have a url pattern.

url(r'^add/$', AddView.as_view(), name="add"),

That view will render rentals/add.html, because you have:

class AddView(TemplateView):
    template_name = 'rentals/add.html'

Rendering the template will fail, because you are using rental in the url tag, but you have not defined rental anywhere.

{% url 'ImageUpload' rental.id %}

Unless your AddView can set rental in the template context, then using the url tag like this will not work.

You need to explicitly pass down the kwarg argument since you defined it in your urls.py : 

var data = {
    urltag: "{% url 'ImageUpload' pk=rental.id %}"
}
