Automatically Set "request.current_app" for all Request

[Luoxzhg]

Django should provide a standrad middleware to add current_app attribute to request objects.

from django.utils.deprecation import MiddlewareMixin

class CurrentAppMiddleware(MiddlewareMixin):
    def process_view(self, request, *args, **kwargs):
        namespace = request.resolver_match.namespace
        request.current_app = namespace if namespace elsel None

Hi Luoxzhg,

Given you can already rely on request.resolver_match.namespace as you've demonstrated in your report I don't see the benefit of providing an alias that hides the fact this app name is actually bound to the URL reversal mechanism. IMHO request.resolver_match.namespace does a good job at exposing this attribute while making its origin clear.

Feel free to bring the discussion to developer mailing list if your disagree with my resolution.

Some functions needs request.current_app to replace current_app argument 。
Add the attribute in every view function is repeatly.
