That follows the stated behavior for "process_view" middleware: https://docs.djangoproject.com/en/1.6/topics/http/middleware/#process_view
process_view is called before the request is passed on to the view function/class. The view is expected to return a response, so the only reason that the middleware should return a response is to circumvent the normal process and return an immediate response without ever calling the view. It's possible you want to use the "process_response" middleware instead if what you're really wanting to do is modify a response object. https://docs.djangoproject.com/en/1.6/topics/http/middleware/#process_response _Nik On 1/3/2014 3:53 PM, jeremiahsav...@gmail.com wrote: > Hello, > > I was wondering why there is a break in this code? > > for middleware_method in self._view_middleware: > response = middleware_method(request, callback, > callback_args, callback_kwargs) > if response: > break > > The reason I ask is I was not able to use > https://github.com/omarish/django-cprofile-middleware unless I > commented out the last two lines. > > My objects look like the following: > > self=<django.core.handlers.wsgi.WSGIHandler object at > 0x7ff3c1320a90> > > self._view_middleware=[<bound method > DebugToolbarMiddleware.process_view of > <debug_toolbar.middleware.DebugToolbarMiddleware object at > 0x7ff3ab62d750>>, <bound method ProfilerMiddleware.process_view of > <django_cprofile_middleware.middleware.ProfilerMiddleware object at > 0x7ff3ab62dad0>>, <bound method CsrfViewMiddleware.process_view of > <django.middleware.csrf.CsrfViewMiddleware object at 0x7ff3ab62db90>>] > > > > With the 'break' included as-is, the 'for' loop was exiting after the > first iteration, as there is a 'response'. > > response=<django.template.response.TemplateResponse object at > 0x7f8d978e1d50> > > and the web page displays the following error: > ------------------------------ > > > AttributeError at /data/taxonomy/1/ > > 'ProfilerMiddleware' object has no attribute 'profiler' > Request Method: GET > Request URL: http://152.16.15.249:8091/data/taxonomy/1/?prof > Django Version: 1.6.1 > Exception Type: AttributeError > Exception Value: > 'ProfilerMiddleware' object has no attribute 'profiler' > Exception Location: > /home/jeremiah/.virtualenvs/auto_p3_d16/lib/python3.3/site-packages/django_cprofile_middleware/middleware.py > in process_response, line 49 > > > ------------------------------------ > > > Without the last two lines, I am able to use the profiler without errors. > > > Is the 'break' needed? > > Thanks, > > Jeremiah > -- > You received this message because you are subscribed to the Google > Groups "Django users" group. > To unsubscribe from this group and stop receiving emails from it, send > an email to django-users+unsubscr...@googlegroups.com. > To post to this group, send email to django-users@googlegroups.com. > Visit this group at http://groups.google.com/group/django-users. > To view this discussion on the web visit > https://groups.google.com/d/msgid/django-users/f3b6731c-d134-4af4-a7f3-092d92350fcd%40googlegroups.com. > For more options, visit https://groups.google.com/groups/opt_out. -- You received this message because you are subscribed to the Google Groups "Django users" group.
