How I can use django MedalForm object and Queryset to do login authentication function
My following question is about how I can develop a function that I can compare a POST request data (MedalForm) and existing data of model in queryset. This is mi models.py: class Employee(models.Model): dni = models.CharField(max_length=9, null=False, blank=False, default="12345678R") name = models.CharField(max_length=7) surname = models.CharField(max_length=8) email = models.CharField(max_length=20) telefone_number = models.IntegerField() user_nick = models.CharField(max_length=10, null=False, blank=False, default="user") password = models.CharField(max_length=20, null=False, blank=False, default="password") ticket = models.ManyToManyField(Ticket) forms.py (EmployerLoginForm only to user_nick and password): class EmployerForm(forms.ModelForm): class Meta: model = Employee fields = "__all__" class EmployerLoginForm(forms.ModelForm): class Meta: model = Employee exclude = ['dni', 'name', 'surname', 'email', 'telefone_number', 'ticket'] In this case, to develop login function I am using the EmployerLoginForm in views.py: _logger = nexus_services_logs.Logging(statics.NEXUS_VIEWS_LOGGING_NAME) _views_manager_service = nexus_services_views_manager.ViewsManagerService() _auth = nexus_services_auth.Authentication() class IndexView(View): def post(self, request, *args, **kwargs): form = EmployerLoginForm(request.POST) if(_auth.check_model_employer_authentication(form, _logger, _views_manager_service)): if(_views_manager_service.validate_form(form, _logger)): _views_manager_service.save_form(form, _logger) return redirect('employerPortal') else: return redirect('index') check_model_employer_authentication(form, _logger, _views_manager_service) is the function where I want compare form data and queryset.

Django pre_save or post_svae is not triggered on through model but post_delete is
So I am working on a google calendar integration. I have users and shifts and in the through model I want to add a google_calendar_id. So right now I have a through model class ShiftUser(models.Model): shift = models.ForeignKey("shift.Shift", models.DO_NOTHING, related_name="shift_users") user = models.ForeignKey(User, models.DO_NOTHING, related_name="user_shifts") google_calendar_id = models.CharField(max_length=1024, null=True) class Meta: unique_together = (("shift", "user"),) But the save method does not work on through model so I added a pre_save on the model: @receiver(pre_save, sender=ShiftUser) def shift_user_change(instance, **kwargs): GoogleIntegration.create_event(instance) I tried this approach with pre_save and post_save but both are not triggered. But when I use post_delete it does work. Does anybody know why this is? For the record. I tried m2m_changed but I need to know which users changed and from what I gathered I can't do that without doing two queries per change in the relationship. This is of course not the worst but I think the pre_save is a cleaner solution. -

Functional Based View: def NewTeam(request): form = NewTeamForm() if request.method == 'POST': form= NewTeamForm(request.POST, request.FILES) if form.is_valid(): form.save(commit = True) return teams(request) else: print("Invalid Form") return render(request,'teamform.html', {'form':form}) FormView I tried class NewTeam(FormView): template_name = 'teamform.html' form_class = NewTeamForm success_url = '.' def get_context_data(self,**kwargs): context = super(NewTeam, self).get_context_data(**kwargs) form = NewTeamForm() if request.method == 'POST': form= NewTeamForm(request.POST, request.FILES) if form.is_valid(): form.save(commit = True) return teams(request) else: print("Invalid Form") context['form'] =form return context I can understand that I need to get the context in the first function and create a new function form_valid. I have seen the documentation and other stack answers but I couldn't get it like how to validate the form with in it. Thanks in Advance. -

Override generics.RetrieveAPIView called with slug field
I'm using generics.RetrieveAPIView in DRF to return details using a slug lookup field. I get the slug from the url www.../slug, and then fetch the required data from the API: http://...api/slug/. It works fine when the user enters the 'slug' in the url however when they login, they don't enter the slug so I set it with code. In my code, I set the slug to anonymous. At this points, I use the User in request to fetch the details but it's not working. Please help. Here's my generics view: class StoreDetail(generics.RetrieveAPIView): lookup_field = 'slug' serializer_class = StoreSerializer def get_queryset(self): if self.kwargs: slug = self.kwargs['slug'] if slug != 'anonymous': # means slug is in URL return Store.objects.filter(slug=slug) else: # manually get slug from db id = self.request.user.id store = Store.objects.get(account=id) slug = store.slug # Everything up to here works however it returns 404(Not found) return Store.objects.filter(slug=slug) -

How does a document/file storage website 'full stack' work?
Hi there Stackoverflow, I have dabbled with coding in the past and built very simple apps with python and java. During the lockdown my mind has become more inquisitive and i'm peeling the onion of how websites, back and front end work. I have sporadically been learning about html, java(script), node.js, nginx, apache, mongoDB, amazon aws, then django, ruby on rails etc etc. However, one thing i haven't been able to find in any one location is the component layers of a website that would hosts files that users might interact with, what the best infrastructure of Full Stack for such a website might be and how the role of each of the languages/interfaces works. I would be very grateful if someone could shed some light on the subject, or direct me to the best place to learn about this. Specifically to my case I would like to know how a file hosting website might work, an example being a legal datasite that can grant users different permissions, or DocuSign contract lifecycle management. Many Thanks. -
Sending image from Android Retrofit to Django server
The problem is that I’m probably sitting already a day and racking my brains. It is required to send a regular multipart / form-data request with an image and several lines. Here is the Retrofit interface code: @Multipart @POST("edit/profile/image") Call<ImageAddResponse> change_avatar(@Part MultipartBody.Part image, @PartMap Map<String, RequestBody> requestBodyMap); There is also a backend to Django. Testing everything locally, everything works perfectly, but when I put django on a real server, I get this error when requesting above: Traceback (most recent call last): File "/usr/local/lib/python3.7/dist-packages/django/core/handlers/exception.py", line 34, in inner response = get_response(request) File "/usr/local/lib/python3.7/dist-packages/django/core/handlers/base.py", line 115, in _get_responseHow to send an object with data and an image in retrofit to Django server response = self.process_exception_by_middleware(e, request) File "/usr/local/lib/python3.7/dist-packages/django/core/handlers/base.py", line 113, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/local/lib/python3.7/dist-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/home/ioienv/ioi/api/views.py", line 349, in edit_user_image userid = request.POST.get('userid' , 1) File "/usr/local/lib/python3.7/dist-packages/django/core/handlers/wsgi.py", line 102, in _get_post self._load_post_and_files() File "/usr/local/lib/python3.7/dist-packages/django/http/request.py", line 326, in _load_post_and_files self._post, self._files = self.parse_file_upload(self.META, data) File "/usr/local/lib/python3.7/dist-packages/django/http/request.py", line 286, in parse_file_upload return parser.parse() File "/usr/local/lib/python3.7/dist-packages/django/http/multipartparser.py", line 154, in parse for item_type, meta_data, field_stream in Parser(stream, self._boundary): File "/usr/local/lib/python3.7/dist-packages/django/http/multipartparser.py", line 640, in __iter__ for sub_stream in boundarystream: File "/usr/local/lib/python3.7/dist-packages/django/http/multipartparser.py", line 464, in __next__ … -
Modifying app_index (AdminSite)
So I'm in the middle of modifying my Django sites admin pages. I'm currently trying to move all apps/models over to a sidebar that will exist on every admin page. This is going pretty well as you can see here my issue now is that the sidebar changes depending on where you are in the admin panel, and I've come to assume that this is due to the app_label here def app_index(self, request, app_label, extra_context=None): app_dict = self._build_app_dict(request, app_label) if not app_dict: raise Http404("The requested admin page does not exist.") # Sort the models alphabetically within each app. app_dict["models"].sort(key=lambda x: x["name"]) app_name = apps.get_app_config(app_label).verbose_name context = { **self.each_context(request), "title": _("%(app)s administration") % {"app": app_name}, "app_list": [app_dict], "app_label": app_label, **(extra_context or {}), } request.current_app = self.name return TemplateResponse(request, self.app_index_template or [ "admin/%s/app_index.html" % app_label, "admin/app_index.html" ], context) as this is the docstring for _build_app_dict Build the app dictionary. The optional label parameter filters models of a specific app. So I followed the docs on customizing the adminsite-class in hopes of being able to overwrite this one function and solve my issues, but sadly when I enable this overwrite no apps at all show up in the sidebar.

Requesting django UpdateView via post method and passing argument
I want to open an UpdateView in Django via post method and I want to pass custom parameter via html input hidden. However, Django tells me that request (from request.POST['parameter']) is not defined. How could I access the post data? I have read a lot how the CBV manages all methods and processes them in some way before it gets translated for the callable the URL conf needs, but I do not understand everything of that. -
