django - Detecting a response redirect in middleware -

-

i have custom middleware creates stack of previous urls can navigated subsequent pages.

in 1 of views adds url stack, there logic can redirect response different page, so:

@middleware_decorator # tells middleware add views url stack when called def some_view(request):     ... stuff ...      if some_condition:         return httpresponseredirect(url, kwargs)

the issue have is, if hit response redirect condition, don't want add current url stack, because when go next page, hit same condition again , redirected page left. have "remove" function in middleware can't call so:

if some_condition:     middleware.remove("this views url")     return httpresponseredirect(url, kwargs)

because view url added in process_response stage of middleware logic reasons occurs after redirect has taken place. hoping there way detecting in middleware after first view has been redirected from- "a redirect has happened" , in middleware can decide whether add or not.

you can set flag in request if should added stack , handle actual adding functioanality in process_response 

process_response(self, request, response):     if request.addtostack , not instanceof(response, httpresponseredirect):         #add url request stack

i expect reference counting should work on outer aggregating object in interface implementation. if can refer example: clarity in classes implementing multiple interfaces (alternative delegation): here minimal reproduction of behaviour: program so16210993; {$apptype console} type ifoo = interface procedure foo; end; tfooimpl = class(tinterfacedobject, ifoo) procedure foo; end; tcontainer = class(tinterfacedobject, ifoo) private ffoo: ifoo; public constructor create; destructor destroy; override; property foo: ifoo read ffoo implements ifoo; end; procedure tfooimpl.foo; begin writeln('tfooimpl.foo called'); end; constructor tcontainer.create; begin inherited; ffoo := tfooimpl.create; end; destructor tcontainer.destroy; begin writeln('tcontainer.destroy called');//this line never runs inherited; end; procedure main; var foo : ifoo; begin foo := tcontainer.create; foo.foo; end; begin main; readln...
