How do I add user data to url in Django?

Question

I've got a function based view in Django called userView

@login_required(login_url='/login/')
def userView(request):
    user = None
    if request.user.is_authenticated():
        user = request.user
        user_id = user.pk


    return render(request, "user_view.html", {'user': user})

and here's my URL for it

urlpatterns = [
     url(r'^user/', userView, name='user'),
]

After my user has logged in, I'd like him to see his pk number in the URL. I.e., if the user's PK is 3 and the user directs their browser to www.myapp.com/user, the URL in the address bar should change to www.myapp.com/user/3/. How do I make that happen? I'm aware I need to edit the RegEx for the URL into

url(r'^user/(?P<user_id>[0-9]+)/$', userView, name='user')

but how do I pass the PK number to the URL?

Not quite clear what you're asking. That URL already requires a user_id, so you can't get to that view without having it in the first place. — Daniel Roseman

I edited the post to make it clearer. How do I pass the pk number to the url from the view — P4nd4b0b3r1n0

I still don't really understand. You're presumably redirecting from login to this view, why can't you put the number into that redirect URL? — Daniel Roseman

So when the user directs their browser to www.myapp.com/user/ you want the URL to change to www.myapp.com/user/3/ (if the user's PK is 3)? — das-g

I am not a Django expert but my guess is you want to redirect the user to his 'home page' after he is logged in. That can be done using the redirect() method

@login_required(login_url='/login/')
def userLoginView(request):
    if request.user.is_authenticated():
        return redirect("/user/{0}".format(request.user.pk), user=request.user)

And then define a second view that will render the home page

def userView(request, user_id=None, user=None):
    return render(request, "user_view.html", {'user': user})

Also your url patterns should be as follows

urlpatterns = [
     url(r'^user/', userLoginView, name='userlogin'),
     url(r'^user/(?P<user_id>[0-9]+)/$', userView, name='user')
]

Even better to use Django's reverse lookup. With your urlpatterns it would look something like: return redirect(reverse('user', kwargs={'user_id': request.user.pk})). That way, if you would ever change your urlconf from user/<id> to, say, profile/<id>, all your redirects still work. See here for details: docs.djangoproject.com/en/1.10/ref/urlresolvers/…
