No Reverse Match Exception

[yingi keme]

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+)/$']

[Любопытный Енот]

try fix your pattern to

r'^/Core/UpdateMe/(?P<pk>\\d+)/$'

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

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...

Instead of User.id, try user.id, capitalization matters.

{% url 'Update' pk=user.id %}

The default context variable provided by django.contrib.auth is 'user' in the template context, not 'User', which I'm assuming you are using.

Since the 'User' variable does not exist in your template context, it resolves to '' (empty string), meaning that you are passing a PK of '' to your view, which it is unhappy with. This is evidenced in the error message you originally posted with an empty string showing as the argument to the URL resolver:

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

HTH,

Trying not to confuse things, but in this instance you may instead want to use object.id, since you may be referring to a different User object than the one that is logged in. I made an assumption that the view will be only modifying the logged in user.

[yingi keme]

You nailed it james. It worked for me. The capitalization matters.

Thanks James..!!!
