DjangoIntegration conflict with MiddlewareMixin & TemplateView #661
Description
django version: 3.0
sentry-sdk version: 0.14.3
My project has a middleware using Django's django.utils.deprecation.MiddlewareMixin. Visiting a view which subclasses django.views.generic.TemplateView while Sentry is active results in the following exception:
AttributeError: 'function' object has no attribute '__self__'
File "django/core/handlers/exception.py", line 47, in inner
response = get_response(request)
File "django/core/handlers/base.py", line 196, in _get_response
middleware_method.__self__.__class__.__name__,
The following classes & url config should be sufficient to demonstrate the problem:
from django.utils.deprecation import MiddlewareMixin
from django.views.generic import TemplateView
# ...in myapp.middleware.py
class DemonstratesConflictMiddleware(MiddlewareMixin):
def process_template_response(self, request, response):
return response
# ...in myapp.views.py
class DemonstratesConflictView(TemplateView):
template_name = "index.html"
# ...in urls.py
import myapp.views
urlpatterns += [
path('/', myapp.views.DemonstratesConflictView.as_view(), name='throws-exception'),
]
# ... in settings.py
MIDDLEWARE += ['myapp.middleware.DemonstratesConflictMiddleware']
sentry_sdk.init(
dsn="OMITTED",
