How do I get a Django redirect to work properly when updating my database?
I can't get my Django redirect to work correctly after updating a bicycle in my Django app. When I use my update_bike view and update the bicycle profile, if my redirect is just to '/bikes', I'm taken back to the bicycle collection/bicycles owned. But when I try and redirect back to the profile of the current bike I'm editing, I get this error that my return pathway doesn't match any of the url patterns. I've pasted the function code here: def bikes_update(request, bike_id): if request.method != 'POST' or 'user_id' not in request.session: return redirect("/") this_bike = Bike.objects.filter(id=bike_id).update( name = request.POST['bike_name'], model = request.POST['model_id'], ) return redirect('/bikes') return redirect('/bikes/<int:bike_id>') return redirect('/bikes/<int:bike_id>/') I obviously comment out the bottom two redirects and the ('/bikes') works fine, it's trying to get back to the current bike profile that doesn't work and gives me the error. I'm able to update the bicycle profile correctly, so it's something to do with this redirect, but I don't get it. I don't understand how line 12 in my screen snippet and the current path (both highlighted in the image), aren't the same/don't match. -
Django while running the server ModuleNotFoundError: No module named 'customer data'
I'm using django to make an API that connects to another one to get some data and update some values. The idea is that the api can be executed from a CLI through commands like upgrade customer_id target_subscription. Before making the CLI file, the api works perfectly if you make requests to it (for example using vs code's thunder client). Once I make the CLI file and try to test I get the following error: Im running the code on Windows 10 and WSL bash. I create the django project using: django-admin startproject customer_data cd customer_data python manage.py startapp customer My file/folder strucutre is this: My API code: class UpdateCustomerSubscriptionView(APIView): def extractCustomerData(self, customer_id): """ Input: A customer id Output: The customer data """ customer = None try: response = requests.get(f'{API_LINK}{customer_id}/') customer_data = response.json() customer = Customer(**customer_data) except: return Response({"error": "The ID does not exist or is badly formated."}, status=500) return customer def upgrade_or_downgrade(self, customer_id, target_subscription): """ Input: A customer id and a target subscription level Output: The updated customer data """ # Validate that the id is not null if customer_id is None: return Response({"error": "The customer id is null."}, status=500) # Validate that the new subscription is not null … -
ManyToManyField constraints
Django ORM seems not to permit constraints on ManyToManyField. class Component(ComponentMetaData): class Type(models.IntegerChoices): Part = 0 Components = 1 type = models.IntegerField( choices=Type.choices, ) components = models.ManyToManyField( "self", blank=True, null=True, ) def clean(self) -> None: if self.type == 0 and self.components: raise ValidationError("Parts could not have components.") return super().clean() class Meta: constraints = [ models.CheckConstraint( check=( Q(type = 0) & Q(components__isnull = True) ) | ( Q(type = 1) # componenets only fields ), name = "components_enum" ) ] Migration attempt with the above model results in the error below; ERRORS: myapp.Component: (models.E013) 'constraints' refers to a ManyToManyField 'components', but ManyToManyFields are not permitted in 'constraints'. Does anyone know why this is not permitted and what should one do if one would like to keep a ManyToManyField empty on some condition based on the values of other fields? -
react oauth2 authentication not working when request is sent
i am trying to integrate social authentication for my react site which i am using drf for the server side, here i am using react-oauth2/google library because the react-google-login npm package seem to be depreciated, so unlike react-google-login that once a request is sent to google from the client side it return an accesstoken and refresh token that is automatically sent to django's end through a callback requesting django authtoken and also sending/comparing users data if any. react-oauth2/google on the other hand tend to only give me just one token called code. i sent it to my server side and it returned wrong credential. error i am using social_django for my drf server side AUTH.JS const GoogleLoginFunc = useGoogleLogin({ flow: 'auth-code', onSuccess: async (codeResponse) => { console.log(codeResponse); // const tokens = await axios.post( // 'http://localhost:3000/auth/google', { // code: codeResponse.code, // }); // console.log(tokens); SocialGoogleLoginFunc(codeResponse.code) }, onError: errorResponse => console.log(errorResponse), }); <GoogleLogin onSuccess={GoogleLoginFunc} // onSuccess={credentialResponse => { // console.log(credentialResponse.credential); // SocialGoogleLoginFunc(credentialResponse.credential) // }} onError={() => { console.log('Login Failed'); }} useOneTap />; GOOGLEAUTH.JS const SocialGoogleLoginFunc=(accesstoken,app_id,app_secret)=>{ // console.log(`MY CREDENTIALS ${app_id},${app_secret}`) // let client_id='nILBGJCOSiaLKDyRZeFpHmUoyDw0PgChrkEGzjkj' // let client_secret='fkUSbr5mtR6oIX3osX51zS1ycbWOfNWGvEjhhKwVQvBb3rJ8gRN1BW2gkFMiPBfBKq3437IC3joXQUEFxPRs1PSXfSgKehOCwoRJoNgjtAzI6ZXwdjyX3RyZfTKKb8hE' // console.log(client_secret.includes(' ')) // http://127.0.0.1:8000/client/auth/convert-token // grant_type:"convert_token", // client_id: client_id, // client_secret: client_secret, // backend:"google-oauth2", // token:accesstoken …
