Streaming Django template with large generator in context
I want to render large log files in a Django template. To do so, the template renders individual lines provided by a generator that streams the log file from disk. The template rendering just stops after some time though and I'm not sure where I've gone wrong. My Django app is running with gunicorn & nginx (config below). I can see that the relevant response headers are set, so I don't know why the logs stop rendering ~30-40 seconds in: HTTP/1.1 200 OK Server: nginx/1.17.4 Date: Wed, 12 Feb 2020 12:53:43 GMT Content-Type: text/html; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive X-Frame-Options: SAMEORIGIN Relevant part of the template: <div class="log-body"> {% for line in log %} {{ line }} {% endfor %} </div> The rendering function in views.py def render_log(request): log = read_log_file_gen("some_path.log") if not log: log = ["No logs found"] template = loader.get_template('show_log.html') context = { 'log': log, } return StreamingHttpResponse(template.render(context, request)) def read_log_file_gen(path): _256KB = 256 * 1024 try: with open(path) as f: while True: lines = f.readlines(_256KB) if not lines: break yield "".join(lines) except IOError: return None The app runs through docker-compose: version: '3' services: web: build: ./app command: gunicorn app.wsgi:application --bind 0.0.0.0:8000 -k gevent volumes: - static_volume:/usr/src/app/static - … -

Django: loading images from URLs (not static files)
I'm trying to load a page in Django with data from an API that include image URLs. I am loading the API data into my modules (example: News module which has a banner_url attribute). In my HTML template, I am loading the banner into an img tag: <img src={{ news.banner_url }}> Obviously this won't work, but I haven't been able to find a solution on the internet. My news module looks like this: class News(models.Model): banner_url = models.URLField(null=True) #null is true for the initialization before a URL is fetched. I tried also using many other fields like CharField and ImageField but to no avail in any way.Any help is appreciated! -
How to send django formset data with ajax and update/create appropriately
I utilised django-extra-views to create a modal which displays a formset. With dynamic-formset-views I've added the functionality to add and remove forms from the formset dynamically. On opening of the modal we follow a many-to-one relationship and get all employees of a certain desk. For each employee instance we create a form. I'm currently trying to send the changes to existing employee and newly added employees with ajax to an api rather than using a django view so I can display potential errors, which come back from the server, in the modal without page reload. Problem: How to serialize the formset data? Is $(form).serialize() appropriate here or do I need to create a a JSON object? How do I distinguish between existing employee which the user modified and new employees which the user added? Do I need to serialize them separately and do a ajax PATCH for the first and an ajax PUT for the second group? Or do I need to configure this behaviour in the api? views.py class DeskEditEmployeesView(AjaxTemplateMixin, ModelFormSetView): model = db_models.DeskEmployeeMap ajax_template_name = 'my_modal.html' form_class = forms.DeskEmployeeMapForm success_url = reverse_lazy('finance:tc_desk') slug_field = 'desk' factory_kwargs = {'extra': 0, 'can_delete': True} api_url = 'api_desk_employee_map-list' template [...] <script language="JavaScript"> … -
Get count as a separate result attribute Django
I need my code to return count for a specific cam id that is active and i want it to return only once and separately. But it is occurring with every single record. My code is as below for model class: def activeness(self): result = MinuteRecords.objects.filter( cam_id=self.cam_id, face_status='Active', ).count() return result For my serializer: class MinuteRecordsSerializer(serializers.ModelSerializer): timeago = serializers.DateTimeField(read_only=True) activeness = serializers.IntegerField(read_only=True) class Meta: model = MinuteRecords fields = '__all__' read_only_fields = ('timeago',) The result that i get is [ { "id": 1, "timeago": "5 days, 21 hours", "activeness": 2, "cam_id": 1, "timestamp": "2020-02-06T14:55:26.852392Z", "face_status": "Active" }, { "id": 6, "timeago": "1 week", "activeness": 2, "cam_id": 1, "timestamp": "2020-02-04T15:17:34.590323Z", "face_status": "Active" } ] The result that i expect is : [ { "id": 1, "timeago": "5 days, 21 hours", "cam_id": 1, "timestamp": "2020-02-06T14:55:26.852392Z", "face_status": "Active" }, { "id": 6, "timeago": "1 week", "cam_id": 1, "timestamp": "2020-02-04T15:17:34.590323Z", "face_status": "Active" }, "activeness": 2, ] The crux being that i want to return the total number of records after my query as a separate record rather than being appended with every result. -

Override default L10N formatting of a date in all edit forms?
In an update view, a DateField in a model form on my site shows an existing date as (say) 2020-01-25. My locale is set to en-GB.utf8. Is there any way to override the defaults arising from USE_I10N globally, in this context only? I would like to get existing dates, in edit form fields only, displayed as 'dd/mm/yy' if I can. Users will otherwise complain that I am forcing them to type in dates in an alien format. I do have DATE_INPUT_FORMATS set to accept %d/%m/%y and it works, but the visual cue is that it won't be accepted (and also they'll have to erase the initial value). I tracked down the DateTimeInput widget documentation and it says format The format in which this field’s initial value will be displayed. If no format argument is provided, the default format is the first format found in DATE_INPUT_FORMATS and respects format localization. "respects format localization" is the problem, meaning it ignores DATE_INPUT_FORMATS. explicitly passing format would solve the problem, except I don't know how to cause this widget setting to become the default for all DateFields in all model forms automatically generated from model and fields in UpdateView for example.

Trigger django-simpleJWT auth manually
I'm trying to repurpose django-rest-framework-simplejwt to authenticate in a completely different way (phone number and SMS validation code in two different requests). The thing is I have everything developed, but due to the tight integration of this auth system in the project I would have to trigger manually the TokenObtainPairView so the user still receives the token and is authenticated in the system. Is there any way I can do that? I thought about triggering the view manually, but that wouldn't work since even if I customize the serializer for that view, I can't override standard username/password for the user (the user doesn't have a password and the username is random) Any ideas on how to do this? My current code is this: class LoginResource(APIView): permission_classes = (permissions.AllowAny,) def post(self, request): payload = json.loads(request.body) try: profile = UserProfile.objects.get(phone=payload.get('phone', '')) code = codegenerator() profile.authentication_code = code profile.save() # TODO: Send the generated code over SMS send_mail( 'Your authentication code', 'Your authentication code is: {}'.format(code), settings.EMAIL_SEND_FROM, (profile.email,), fail_silently=False, ) payload = { "status": "success" } return JsonResponse(payload, status=200, safe=False) except Exception as e: payload = { "status": "error", "message": "Unable to obtain the user: {}".format(e) } return JsonResponse(payload, status=500, safe=False) class ValidateCodeAndLogin(APIView): … -

How can I use a custom logging handler with django?
I'm trying to integrate logging with loki in my django app like this: handler = logging_loki.LokiHandler( url="http://localhost:3100/loki/api/v1/push", tags={"app": "django", "env": ENV}, version="1", ) LOGGING = { # some logging configs } What do I need to change so that django uses this custom handler? I tried just referencing the handler object in the logging dict but that didn't need to be the right approach. -
