QUESTION

How to invalidate a view cache using django-cacheops

Asked 2022-Mar-19 at 15:05

I have a view and I cached it in views.py using django-cacheops (https://github.com/Suor/django-cacheops):

@cached_view(timeout=60*15)
@csrf_exempt
def order(request, usr):
    ...

The regex for order view in urls.py:

url(r'^order/(?P<usr>\D+)$', views.order, name='ord')
# Example Url: http://127.0.0.1:8000/order/demo (demo is the user name)

And I want to invalidate the cached view order inside the below view:

@login_required 
def available(request, pk, avail):
    pk = int(pk)
    avail = strtobool(avail)
    if avail:
        Product.objects.filter(id = pk).update(available = True)
    else:
        Product.objects.filter(id = pk).update(available = False)
    return HttpResponseRedirect(reverse_lazy('yc')) 

According to the docs, we can achieve this by doing:

@login_required 
def available(request, pk, avail):
    pk = int(pk)
    avail = strtobool(avail)
    if avail:
        Product.objects.filter(id = pk).update(available = True)
        order.invalidate("http://127.0.0.1:8000/order/demo", "demo")
        #it's a dummy url I've handled it dynamically in my code
    else:
        Product.objects.filter(id = pk).update(available = False)
        order.invalidate("http://127.0.0.1:8000/order/demo", "demo")
        #it's a dummy url I've handled it dynamically in my code
    return HttpResponseRedirect(reverse_lazy('yc')) 

But it's not working. Here are my logs using redis-cli monitor:

It looks like it's deleting some other cache.

I've also raised the issue in the repo of django-cache, you can check it for more information: https://github.com/Suor/django-cacheops/issues/425

ANSWER

Answered 2022-Mar-19 at 14:37

Since you used a named group usr in your regex, Django passes it as a keyword argument:

url(r'^order/(?P<usr>\D+)$', views.order, name='ord')

But you are trying to invalidate the cache with a positional argument:

order.invalidate("http://127.0.0.1:8000/order/demo", "demo")

Instead, invalidate it with the corresponding keyword argument:

order.invalidate("http://127.0.0.1:8000/order/demo", usr="demo")
