How to give a dropdown a specific value after filling it with database values in Django?
I have in my Views.py a query which I'm using to populate a dropdown. It works well, except that I need it to show a specific value, stored in a variable that corresponds to the user's selection. Let's say we have a dropdown which is filled from a database ('world') using the following query: continents = world.objects.values_list("continents").distinct() So this fills my dropdown with continent names. If the user as previously selected 'Europe' (stored in sel_continent variable), how do I amend this query so it selects 'Europe' after having filled the dropdown? -
Django - Get raw request path
How do I get the raw request path (everything after the host name) in Django? I tried request.get_full_path(), but it doesn’t work for some URLs. For example, when the URL is http://localhost:8000/data/?, the result is /data/ instead of /data/?. I know that the server receives the full string because it show "GET /data/? HTTP/1.1" 200 642 in the terminal. -
Cache switching for django restframework
I set the cache with this in urls.py router = routers.DefaultRouter() router.register('mytexts',MyTextViewSet,basename='mytexts') in view.py class MyTextViewSet(viewsets.ModelViewSet): @method_decorator(cache_page(60*60*2)) @method_decorator(vary_on_cookie) def list(self,request,*args,**kwargs): It works for caching for api myapp.com/my_text/api/mytexts However I want to off the cache sometimes with query myapp.com/my_text/api/mytexts?cacheoff=1 Is it the good practice? if so where should I set?? -
403 Forbidden and can't understand why Angular Django
I'm pretty new to Django & Angular, i'm building a project with authentication. The authentication seems to work well, but when i'm connected, i only got a 403 error on every request i do. Everything in the frontend seems to work but i can't access my views or viewsets. My frontend code is as follows (players-list.component.ts): ngOnInit() { this.playerService.list().subscribe(response => { this.playerList = response.body; }); } Here is my players.service.ts : export class PlayersService { constructor(private http: RestService) {} public list(): Observable<any> { return this.http.list("players"); } } Now my list method in rest.service.ts : public list<T>(endpoint: string, getParams: any = {}): Observable<any> { const inline: string = this.getInlineGetParams(getParams); return this.http.get<T>(`${RestService.API_ROOT}/${endpoint}/${inline}`, { headers: { ...RestService.DEFAULT_HEADERS }, observe: "response" }); } Every console.log i do in this frontside code works. My django views are as follows : class PlayersViewSet(HasRoleMixin, ModelViewSet): queryset = Player.objects.all() serializer_class = PlayerSerializer def list(self, request, *args, **kwargs): print ('sdmlkfnqmfndn') #This doesn't print return super.list(request, *args, **kwargs) def get_queryset(self): return self.queryset.all().order_by("number") My print in my viewset doesn't print. So I guess the 403 error is raised before entering the viewset. Here is my urls.py : router = routers.DefaultRouter() router.register(r"players", PlayersViewSet) urlpatterns = [ url(r'^auth', AuthAPIView.as_view()), url(r'^admin/', admin.site.urls), ] urlpatterns … -

Django App to django-rest-framework ONLY BACKEND
I just created an app in Django that works nicely, but, since I am just a backend programmer, they asked me to migrate to django-rest-framework and leave someone expert the frontend work in VUE. Then I have to translate all of my code so that it could work using django-rest-framework and VUE. I learned Django by myself and I just watched a tutorial for django-rest-framework. I understand what I have to do is to create serializers instead of forms and use viewset, is that correct? How would you approach just the backend work monitoring that anything works fine? What is the fastest way to migrate everything? I'm sorry I seem stupid in yhis but at the moment I can't understand what is the best way to approach this problem... -

Groups and channel layers make the process stop without raising exceptions
Starting with this very simple working code sample: from channels.generic.websocket import JsonWebsocketConsumer class IsacomptaManagementFeesConsumer(JsonWebsocketConsumer): pass When connecting to this websocket consumer from javascript, this works as expected. The connection is issued properly and I get the following logs: WebSocket HANDSHAKING /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38108] WebSocket CONNECT /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38108] WebSocket DISCONNECT /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38108] Now, if I change my code to the following code, to use groups: from channels.generic.websocket import JsonWebsocketConsumer class IsacomptaManagementFeesConsumer(JsonWebsocketConsumer): groups = ['foobar'] Then, the connection fails. JavaScript console tells me: Firefox can’t establish a connection to the server at ws://antoine.cocoonr.hq:3001/manager/accounting/isacompta/2020/03/management-fees.ws. error { target: WebSocket, isTrusted: true, srcElement: WebSocket, currentTarget: WebSocket, eventPhase: 2, bubbles: false, cancelable: false, defaultPrevented: false, composed: false, timeStamp: 7804, … } And the server logs look like this: WebSocket HANDSHAKING /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38128] WebSocket DISCONNECT /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38128] No exception is raised on the server side though. I can also get a similar behavior without using groups. Let's take a bit bigger working code sample: from channels.generic.websocket import JsonWebsocketConsumer class IsacomptaManagementFeesConsumer(JsonWebsocketConsumer): def connect(self): print("one") self.accept() print("two") self.send_json({'text': "Foobar"}) print("three") This code works fine, the connection is issued properly and here are the server logs: WebSocket HANDSHAKING /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38168] one WebSocket CONNECT /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38168] two three WebSocket DISCONNECT /manager/accounting/isacompta/2020/03/management-fees.ws [192.168.96.1:38168] … -
Django does not send emails via smtp
hope someone can help me with this. i have 3 days in a row trying to fix this issue but i could not get anywhere and its making me crazy. this is the issue: im trying to send a email via smtp using django. when i try to send the email, i do not get any error, but my application does not respond and it keeps waiting on to send the email, but obviously it does not send nothing. i have tried with smtp gmail and smtp hotmail, but it is not working. i have already checked my windows firewall, and again it is not working. i have tried to send the email using python shell but it does not send nothing. i think that i have tried almost everything that i saw on the other posts here in stackoverflow, hope someone can help me. settings.py: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.office365.com' EMAIL_PORT = 587 EMAIL_HOST_USER = 'myemail@hotmail.com' EMAIL_HOST_PASSWORD = 'mypassword' SERVER_EMAIL = EMAIL_HOST_USER -
Trying to link two models together in Django: challenges
Trying to work through linking two models or combining the two in a way that doesn't create an error. I have one model, which is just a FileField and accepts an uploaded file class FitFiles(models.Model): fitfiles=models.FileField(upload_to='PMC/fitfiles' null=False) I have another model that is populated under the same upload function and basically runs some calculations based on the file uploaded class RideSum(models.Model): fitfiles = models.OneToOneField(FitFiles, on_delete=models.CASCADE) ftp = models.IntegerField() norm_power = models.IntegerField() intensity = models.FloatField() tss = models.FloatField() date = models.DateField() Issue with the approach above is that I keep getting an error that fitfiles_id is not found. I've tried just putting everything under one model, but the issue there is that filefield 'fitfiles' returns a null value and I get a not-null constraint error. Was curious for advice on how to handle. At the moment I can do things just fine with these two models completely separated (i.e. not trying to link the two), but with the DetailView I need to make sure these always have the same pk and if for whatever reason the primary keys become misaligned between these models then the DetailView becomes a mess of different information. Happy to post and clarify -
How to strip the Prometheus response content in Django?

Django filter geometry given a coordinate
I want to get a polygon from a postgis table given a coordinate/point. With raw sql I do it with: SELECT * FROM parcelas WHERE fk_area=152 AND ST_contains(geometry,ST_SetSRID(ST_Point(342884.86705619487, 6539464.45201204),32721)); The query before returns one row. When I try to do this on django it doesn't return me any row: from django.contrib.gis.geos import GEOSGeometry class TestView(APIView): def get(self, request, format=None): pnt = GEOSGeometry('POINT(342884.86705619487 6539464.45201204)', srid=32721) parcelas = Parcelas.objects.filter(fk_area=152,geometry__contains=pnt) #Also tried this #parcelas = Parcelas.objects.filter(fk_area=pk,geometry__contains='SRID=32721;POINT(342884.86705619487 6539464.45201204)') serializer = ParcelasSerializer(parcelas, many=True) return Response(serializer.data) Even with django raw query it fails although in this case it returns me an internal server error (argument 3: : wrong type): class TestView(APIView): def get(self, request, format=None): parcelas = Parcelas.objects.raw('SELECT * FROM parcelas WHERE fk_area=152 AND ST_contains(geometry,ST_SetSRID(ST_Point(342884.86705619487, 6539464.45201204),32721))') for p in parcelas: #Internal server error print(p.id) return Response('Test') My model parcelas look like this: from django.contrib.gis.db import models class Parcelas(models.Model): id = models.BigAutoField(primary_key=True) fk_area = models.ForeignKey(Areas, models.DO_NOTHING, db_column='fk_area') geometry = models.GeometryField() class Meta: managed = False db_table = 'parcelas' I don't know what I'm doing wrongly if someone has any idea. -
Django(2.11) simultaneous (within 10ms) identical HTTP requests
Consider a POST/PUT REST API (using DRF). If the server receives request1 and within a couple of ms request2 with identical everything to request1 (duplicate request), is there a way to avoid the request2 to be executed using some Django way? Or Should I deal with it manually by some state? Any inputs would be much appreciated. -

Download Button option in Django
I am working on a project which takes some files as input and then gives an output result file to the user. The output file is generated in the backend and takes significant time.

error: "unsupported_grant_type" from django oauth2 server
Not sure why django won't accept my POST request for an access token. All my parameters are correct and I already have the authorization code, but a follow-up POST request for the access token gives me this error. Content-type is correct from what I read from others. If the pkce side was non-accurate it would give me a more specific error about that. HttpErrorResponse is { error: "unsupported_grant_type" } 400 bad request requestToken(code: string, state: string) { const clientState = sessionStorage.getItem('pkce-state'); if (clientState !== state) { console.error('States do not match!'); } const verifier = sessionStorage.getItem('pkce-verifier'); const params = new URLSearchParams({ grant_type: 'authorization_code', redirect_uri: 'http://localhost:4200/dashboard', client_id: 'client_id', code, state, verifier }); return this.http.post('http://localhost:8000/o/token/', { params }, { withCredentials: true, headers: new HttpHeaders({ 'Content-Type': 'application/x-www-form-urlencoded' } ) }); } Also tried this: requestToken(code: string, state: string) { const clientState = sessionStorage.getItem('pkce-state'); if (clientState !== state) { console.error('States do not match!'); } const verifier = sessionStorage.getItem('pkce-verifier'); return this.http.post('http://localhost:8000/o/token/', { grant_type: 'authorization_code', redirect_uri: 'http://localhost:4200/dashboard', client_id: 'client_id', code, state, verifier }, { withCredentials: true, headers: new HttpHeaders({ 'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json' } ) }); }
