From this:
<a href="{% url 'Update' pk=User.id %}">Update</a>

Change to this:
<a href="{% url 'Update' pk={{User.id}} %}">Update</a>

That will not work and isn't recommended. Everything within {% %} is python code already, so you don't need to interpolate again. I don't even think that will work.

Unfortunately I don't have any suggestions to get it working either...

The problem is that, it works perfectly when i put the number on the template like this

<a href="{% url 'Update' 34 %}">Update</a>

But when i do 

<a href="{% url 'Update' pk=User.id %}">Update</a>

It gives the No Reverse Error. I dont seem to understand why

I am using the django generic UpdateView

class UserUpdate(UpdateView):

    model = User

    fields = ['first_name', 'last_name', 'email', 'username']

    template_name = 'Core\MyUpdate.htm'

And my url pattern is this:

url(r'^UpdateMe/(?P<pk>\d+)/$', UserUpdate.as_view(), name='Update')

However, this url  Core/UpdateMe/34/ doesnt seem to match and it gives this error

NoReverseMatch at /Core/UpdateMe/34/

Reverse for 'Update' with arguments '('',)' not found. 1 pattern(s) tried: ['Core/UpdateMe/(?P<pk>\\d+)/$']
