I'm implementing a new middleware using a standard implementation:
def my_middleware(get_response):
def middleware(request):
return get_response(request)
return middleware
I want to get the view_args. I can change to a class-based middleware and implement the method
process_view(request, view_func, view_args, view_kwargs)
Is there any other way to get these view_args, view_kwargs in my middleware without changing to class-based middleware?
set process_view(...) as an attribute of middleware(...) function as
def process_view(request, view_func, view_args, view_kwargs):
"""
do something
"""
def simple_middleware(get_response):
# One-time configuration and initialization.
def middleware(request):
# Code to be executed for each request before
# the view (and later middleware) are called.
response = get_response(request)
# Code to be executed for each request/response after
# the view is called.
return response
middleware.process_view = process_view
return middleware
*process_view() should return None or a HttpResponse object otherwise there is error.
The function with process_view():
def process_view(request, view_func, view_args, view_kwargs):
# Do something
def simple_middleware(get_response):
# One-time configuration and initialization.
def middleware(request):
# Code to be executed for each request before
# the view (and later middleware) are called.
response = get_response(request)
# Code to be executed for each request/response after
# the view is called.
return response
middleware.process_view = process_view # Here
return middleware
The class with process_view():
class SimpleMiddleware:
def __init__(self, get_response):
self.get_response = get_response
# One-time configuration and initialization.
def __call__(self, request):
# Code to be executed for each request before
# the view (and later middleware) are called.
response = self.get_response(request)
# Code to be executed for each request/response after
# the view is called.
return response
def process_view(self, request, view_func, view_args, view_kwargs):
# Do something
