I want to add a parameter somevar to my listview:

{% url 'products' somevar %}?"

in the urls:

path("products/<int:somevar>", ProductListView.as_view(), name = 'products'),

in the views:

class ProductListView(ListView):
    def get_template_names(self):
        print(self.kwargs) # {"somevar": xxxxx}
        return f"{TEMPLATE_ROOT}/products.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        self.get_products().order_by("number")
        print(kwargs) # kwargs is {} here
        return context
    
    def get_queryset(self):
        return super().get_queryset().order_by("number")

How can I pass the variable to the get_context_data method? I tried defining a get method and call self.get_context_data(**kwargs) within, but this leads to an object has no attribute 'object_list' error.

CodePudding user response：

The View class has different kwargs than the get_context_data method

The kwargs of a View contain the URL Parameters

The kwargs passed to the get_context_data method are passed to the template for rendering

Since you want to access a URL Parameter in get_context_data you would use self.kwargs (self is referring to your View class)
