I'm using Python 3.7, Django 3.1.7, social-auth-app-django 3.1.0.
I've just started playing with async views. I can't get them to play nice with LoginRequiredMixin. I've got this trivial view:
class TestView(LoginRequiredMixin, View):
#classonlymethod
def as_view(cls, **initkwargs):
view = super().as_view(**initkwargs)
view._is_coroutine = asyncio.coroutines._is_coroutine
return view
async def get(self, request):
return render(request, 'spi/test.jinja', {})
When I run this test:
class TestViewTest(ViewTestCase):
def test_get(self):
client = Client()
response = client.get('/spi/test')
self.assertEqual(response.status_code, 200)
It fails with an awe-inspiring stack dump (below), the gist of which is:
TypeError: object HttpResponseRedirect can't be used in 'await' expression
which I assume is due to the OAuth flow being run. If I leave out the LoginRequiredMixin, the test passes.

Well, it turns out the problem is simply that LoginRequiredMixin isn't async-capable yet. The work around is to implement the gist of LoginRequiredMixin in my view code. The supplied implementation of LoginRequiredMixin is complicated, but most of it is dealing with the general case. Stripping it down to the essential part that fits my use case, I ended up with:
from asgiref.sync import sync_to_async
from django.contrib.auth.views import redirect_to_login
class TestView(View):
#classonlymethod
def as_view(cls, **initkwargs):
view = super().as_view(**initkwargs)
view._is_coroutine = asyncio.coroutines._is_coroutine
return view
async def get(self, request):
if not await sync_to_async(lambda: request.user.is_authenticated)():
return redirect_to_login(self.request.get_full_path())
return render(request, 'spi/test.jinja', {})

I'm trying to catch a ValueError that occurs due to the skip parameter equal to a negative number. For example,
try:
MyModel.objects.skip(-1)
except ValueError as error:
print(error)
does not do anything. It doesn't error out with ANY message nor does it do anything else. What I want is just to catch the ValueError and handle it appropriately.
If I except TypeError (that is not raised) instead of ValueError it displays the same behaviour.

I have strange problems
I have next code Using TesCase and APIClient to get request with token
class Profile(TestCase):

self.token = Token.objects.create(user=self.user)

response = self.client.get('/api/some-username/profile/')
print(response.status_code)

Authorization goes well,but the I received error. If i use requests.get with headers (token) to development django server all pass well i receive a correct json response

How know what is the problem?
I just updated my code from django 1.8 to 1.11 and so i also had to update tasty pie. Before update everything worked fine but now I am getting this error on one of my tests.
Here is the test case
def test_does_not_return_restricted_fields_when_insufficient_permissions(self):
self.user.user_permissions.all().delete()
response = self.api_client.get(url,
format='json',
authentication=self.create_apikey(username=self.username, api_key=self.api_key),
data=data)
Here is the full Trace,

TypeError: build_filters() got an unexpected keyword argument 'ignore_bad_filters'
Could your please paste your tastypie resource code?
Without related code, I can only guess that it is because you override
def build_filters(): in your modelresource class, but the newer version of tastypie added a ignore_bad_filter parameter in the function definition which you do not have in your modelresource code.
The build_filters function declaration in the latest tastypie:
def build_filters(self, filters=None, ignore_bad_filters=False):
The old version probably does not have the ignore_bad_filter parameter. To fix this, just add ignore_bad_filters=Falsekey word parameter to the build_filters function in your modelresource class.
Here's the scenario. I have a Django app being served by Gunicorn on Linux. On certain requests it makes an https call to an external API via httplib2.request(). Sometimes that call fails in such a way that hoses OpenSSL (not sure how, but it's not my fault and doesn't really matter). OpenSSL sends a SIGABRT signal to gunicorn in this case. Gunicorn handles the SIGABRT and promptly system exits (as it should).
The root issue as I see it is that OpenSSL asynchronously signals the parent process to abort, rather than returning an error code. Don't tell me to abort because of YOUR personal problems, OpenSSL! Legacy code in action.
Is anyone else thoroughly annoyed by this problem? How would you prevent this from killing your Gunicorn process? It completely bypasses Django exception handling.
Relevant code points:
OpenSSL sends SIGABRT whenever OpenSSLDie() is called: https://github.com/openssl/openssl/blob/e0fc7961c4fbd27577fb519d9aea2dc788742715/crypto/cryptlib.c#L391
which comments claim happens whenever there is a fatal error in any cryptographic operation: https://github.com/openssl/openssl/blob/e0fc7961c4fbd27577fb519d9aea2dc788742715/fips/fips.c#L136
The SIGABRT is handled by gunicorn: https://github.com/benoitc/gunicorn/blob/6eb01409da42a81b7020cd78c52613d8ec868e94/gunicorn/workers/base.py#L173
which causes gunicorn to sys.exit(1): https://github.com/benoitc/gunicorn/blob/6eb01409da42a81b7020cd78c52613d8ec868e94/gunicorn/workers/base.py#L200
I don't think the signal gets created by OpenSSL. The signal comes from gunicorn which sends this signal if the request takes too long.
worker_abort(worker): Called when a worker received the SIGABRT signal.
This call generally happens on timeout.
The callable needs to accept one instance variable for the initialized
Worker.
