How can i route request to specific views according to parameters in Django?-CodePudding

I created an API with Django and i am trying to route requests to different views for optimization purposes.

Here is what i'm trying to do: if the GET request is 127.0.0.1:8000/api/sales/?key=<KEY>&some_query=<some_value>&... that query should be handled by a view called sales. If the GET request contains a specific parameter called sale_value the request should be routed to another view called large_sales, for example 127.0.0.1:8000/api/sales/?key=<KEY>&sale_value=<INT>... should be handled from the large_sales view.

Here is what i tried:

urlpatterns = [
    path('sales/', views.sales, name="sales"),
    path('sales/sale_value<int:num>', views.large_sales, name="large_sales"),
]

This will route all the requests to sales. How can i do this? Maybe with regex?

Edit: i can't handle this logic directly in the view because i want to cache these two queries with different TTL. Example:

@cache_page(1.5)
def sales(request):
...


@cache_page(10)
def large_sales(request):
...

CodePudding user response：

def sales(request):
    try:
        sale_value = request.GET['sale_value']
    except:
        return redirect(large_sales, num=11) # replace 11 with your number.

or try to use if condition (if sale_value != None:)

CodePudding user response：

You can write a view which accesses request.GET and redirects accordingly.

You may also need to put defensive code in the view that you redirect to, to make sure that a user (or attacer) is not getting creative with completely insecure GET parameters!

With a class-based view you can subclass get ...

class SalesView( some_CBV_class):
    ...

    def get( self, request, *args, **kwargs):
         if request.GET.get( 'sale_value', None):
             target = reverse('app:large_sales', kwargs={...} 
                  )   '?'   request.GET.urlencode()
             return HttpResponseRedirect( target)
         return super().get( request, *args, **kwargs)

and for safety, maybe

class LargeSalesView( ...)

    def get( self, request, *args, **kwargs):
         if request.GET.get( 'sale_value', None) is None
             target = reverse('app:sales', kwargs={...} 
                  )   '?'   request.GET.urlencode()
             return HttpResponseRedirect( target)
         return super().get( request, *args, **kwargs)
