@liyanhui1228 we really appreciated the trace context feature to group logs by request.
Unfortunately, it looks broken with Django 2.

Django 1.10 introduced a new middleware style ( https://docs.djangoproject.com/en/1.10/releases/1.10/#new-style-middleware )

The old style, used by google.cloud.logging.handlers.middleware.request.RequestMiddleware, support was removed with Django 2.
