hello everyone am stack with some error in django am working on an ecommerce application here is the error code.

i have aswell attached my template and the views.py file

NoReverseMatch at /products/beef/

' cart' is not a registered namespace

Hi Lutalo,

' cart' is not the same as 'cart'. Notice the leading space.

That is mostly likely the cause of your error. Notice how you are
writing the "action" attribute in "form-product-ajax" in your
update-cart.html file.

Kind regards,

Kasper Laudrup

in cart app urls.py did you write 

app_name = 'cart'

[Exactly musty]

The way you wrote your django url is not correct,the " should be like the "cart" not " cart " python count empty space
