is that really not possible in the Django ORM?
In my 10 years playing with Django i found a few bugs, but i never had to fall back to a raw SQL query. Fiddling with Django for almost a full day now im out of ideas except of asking for help here: I have an organizer app with days containing shifts and people working those shifts (M2M). There also are supervisors for each day that are directly stored on the day (M2M). For the user stats i want to see who has how many shifts. For speed reasons i WANT to handle this with only one query. Here is the query i ended up with: assigned_to = self.shifts.filter(day_id=OuterRef('id')).order_by() days = Day.data.filter(date__range=(start, end)).distinct().annotate( assigned_shifts=Count( Subquery(assigned_to.values('id')) )).annotate( assigned_pl=Max(Case( When(production_managers=self, then=1), default=0, output_field=models.IntegerField(), distinct=True ))).annotate( assigned_tl=Max(Case( When(day_managers=self, then=1), default=0, output_field=models.IntegerField(), distinct=True ))).annotate( assigned_al=Max(Case( When(managers=self, then=1), default=0, output_field=models.IntegerField(), distinct=True ))).annotate( assigned_cash=Max(Case( When(cash_managers=self, then=1), default=0, output_field=models.IntegerField(), distinct=True ))).order_by() This is giving me an SQL error "more than one row returned by a subquery used as an expression", tho. Without the subquery i was getting false values - probably because the grouping didnt work out as its supposed to. Turns out there is a warning in the docs and a very old ticket (https://code.djangoproject.com/ticket/10060) warning … -

Map custom defined url path to included url path
I would like to map a url path /register to an included url path, rest-auth/registration. For example, if I type in localhost:3000/register, it would map to localhost:3000/rest-auth/registration. Currently I am simply using: url(r'^rest-auth/registration/', include('rest_auth.registration.urls')) where rest_auth.registration.urls is from the rest_auth framework I am using. Woulda anyone know how I could achieve this? Thank you. -

How should I configure Redis for Django Channels 2.0?
I'm getting an error sometimes when I run a Worker of Django Channels as Background Task. The task consumes an open third-party WebSocket with a library called Pysher, processes that data and then sends the resulting data through the Channel Layer to a group of Websockets listening to our application using Redis (the Message Broker). I know that the problem does not have to do with the Pysher library, since if I comment the code to send the message through the Channel Layer runs whitout problems. The problem occurs due to the sending of the message in the Channel Layer and only happens sometimes, many times the sending occurs successfully and other times it throws the error, the last behaviour makes me think that it may have to do with Redis or the Channel Layer and its configuration or something like that, maybe Redis is getting some limit.

Pandas create month end holding from activity
I am trying to find the month-end balance amounts based on the "issues" held from the df_td list of activity. Actually I am just looking to find the count of "issues" with a positive balance at the end of each month. To do this I need to create the month-end balance based on each "issues" "action" and "shares" on activity less than the month-end date. So the total count of issues with a balance > 0 for each period. The "action" is used to know if it is a buy or a sell, "+" or "-". So the balance is "+ shares" less "- shares" per each "issue." Previously I used sql to do this but that seems like a serious waste. What is best way to do this with Pandas? df_td action code comm credit date \ 0 + P 0.00 0.00 2013-03-27 1 + P 0.00 0.00 2013-03-27 2 - S 19.00 86751.01 2013-04-08 3 + Z 2000.00 0.00 2013-04-09 4 - S 18.71 730.49 2013-04-10 issue \ FIDELITY REAL ESTATE INVESTMENT PORTFOLIO FUND FIDELITY NJ MUNICIPAL INCOME FUND FIDELITY REAL ESTATE INVESTMENT PORTFOLIO FUND AMERICAN RLTY CAP HEALTHCARE TR INC FIDELITY NJ MUNICIPAL INCOME FUND price shares … -
My template breaks when i turn off debug mode in python django
When I turn off debug mode in settings.py, one of my templates breaks. The template references a header.html and a footer.html. The header.html renders to the page, but the footer.html does not. Is there something with the staticfiles settings that I'm not taking care of? Since the templates don't reside with the other staticfiles, I didn't think it would be related to this issue but perhaps it is. I am using the django-heroku package to auto-configure the staticfiles. -

Django sending wrong filename with UUID based download
Folks, I'm having an issue that I can work around, but I'd prefer not to. I just rewrote my gallery application, to use a UUID based database index for the download. Eg. url(r'^(?i)download/(?P<d_uuid>.+)/', frontend.views.new_download, name="downloads"), So download/ will lookup the file by searching for the UUID, and then serve it out. def new_download(request, d_uuid=None): download = index_data.objects.filter(uuid=d_uuid, ignore=False, delete_pending=False)[0] print ("\tDownloading - %s, %s" % (download.fqpndirectory.lower(), download.name)) return serve(request, download.name, download.fqpndirectory.lower()) This was working properly before I switched to using the UUID search. It appears that the browsers (firefox, Safari, etc), are grabbing the filename from the GET. Now, I've tried using, this instead of serve: respond_as_attachment(request, download.fqpndirectory, download.name) def respond_as_attachment(request, file_path, original_filename): # https://www.djangosnippets.org/snippets/1710/ # print ("original filename: ", original_filename) fp = open(file_path + os.sep + original_filename, 'rb') response = HttpResponse(fp.read()) fp.close() type, encoding = mimetypes.guess_type(original_filename) if type is None: type = 'application/octet-stream' response['Content-Type'] = type print (response['Content-Type']) response['Content-Length'] = str(os.stat(file_path).st_size) if encoding is not None: response['Content-Encoding'] = encoding filename_header='filename="%s"' % original_filename response['Content-Disposition'] = 'attachment; ' + filename_header return response Without any change in behavior.

How to send request body for DELETE in Django Rest Framework
So I am trying to send a request body for DELETE in DRF. I know by default,DRF doesn't support bulk operations so I am using django-rest-framework-bulk. Now as per the tutorial, I am making sure the bulk deletes are allowed only when the query is filtered.I am using BulkModelViewset. Consider this json array: [{ "id": "1", "first_name": "bruce", "second_name": "banner", "team": "avengers" }, { "id": "2", "first_name": "clark", "second_name": "kent", "team": "Justice League" } { "id": "3", "first_name": "dead", "second_name": "pool", "team": "x force" }] Now the I could delete in bulk by passing a filter like : DELETE /api_name/?first_name=bruce,clark But my frontend people want to send a request body because if there are 100 objects which are needed to be deleted, they are not expected to send 100 ids as comma separated string in query parameter. I am new to REST principles so there could be fault in my entire logic. I tried to find answers online but couldn't find something specific.Thanks Sample Viewset: class TeamViewSet(BulkModelViewSet): serializer_class = TeamViewSerializer queryset = TeamView.objects.all() filter_backends = (DjangoFilterBackend,filters.OrderingFilter,) filter_class =TeamViewFilter ordering = ('id','second_name','first_name','team') def allow_bulk_destroy(self, qs, filtered): return filtered -
Django: What's the best way to save Integer Bins in a Model?
What's the best way to save data to a model that is collected in bins.

All the links are unclickable as well.. Is there anything i'm missing to make this work? The css loads fine (200 OK in the server shell) and I have bootstrap functionality otherwise.. I'm new to both django and bootstrap so I hope you can point me in the right direction.. -
Django User permissions/views?
I'm using Django class based views. views.py class ReportListView(LoginRequiredMixin, ListView): model = Report def get_queryset(self): queryset = Report.objects.filter(user=self.request.user) return queryset class ReportDetailView(LoginRequiredMixin, DetailView): model = Report class ReportUpdateView(LoginRequiredMixin, UpdateView): model = Report class ReportCreateView(LoginRequiredMixin, CreateView): model = Report class ReportDeleteView(DeleteView): model = Report As you can see, these are the most generic views, but they should all represent data for only the current user. Currently any user can see/view other users data. One way I saw was that people would define their get_queryset method, like above. This approach only filters rendered data, but the user can still access forbidden data through url (provided he knows/guesses the id). How can I restrict access to other users resources?
