Docker and CloudSQL proxy
I'm having problems connecting my Django server to my Postgres database hosted on Google Cloud through CloudSQL Proxy with Docker. Currently, I have a Docker compose file that looks like this version: '3' services: cloud-sql-proxy: image: gcr.io/cloudsql-docker/gce-proxy command: /cloud_sql_proxy --dir=/cloudsql -instances=gamr-335802:us-central1:gamr=tcp:0.0.0.0:5432 -credential_file=/django_backend/gamr-335802-e8f23fcc176c.json ports: - "5432:5432" volumes: - /cloudsql:/cloudsql - ./gamr-335802-e8f23fcc176c.json:/django_backend/gamr-335802-e8f23fcc176c.json restart: always gamr-backend: build: ./ command: ./runner.sh volumes: - .:/django ports: - "8000:8000" depends_on: - cloud-sql-proxy I think it may be an issue with the volumes of the cloud-sql-proxy but I'm not certain.

display only some fields in get api response django serializer
I have an example model which has a fk relation with user model and Blog model. Now I have a get api which only requires certain fields of user to be displayed. My model: class Example(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, related_name="user_examples", ) blog = models.ForeignKey( Blog, on_delete=models.CASCADE, null=True, related_name="blog_examples", ) /................./ Now my view: class ExampleView(viewsets.ModelViewSet): queryset = Example.objects.all() serializer_class = ExampleSerializer def list(self, request, *args, **kwargs): id = self.kwargs.get('pk') queryset = Example.objects.filter(blog=id) serializer = self.serializer_class(queryset,many=True) return Response(serializer.data,status=200) My serializer: class ExampleSerializer(serializers.ModelSerializer): class Meta: model = Example fields = ['user','blog','status'] depth = 1 Now when I call with this get api, I get all example objects that is required but all the unnecessary fields of user like password, group etc . What I want is only user's email and full name. Same goes with blog, I only want certain fields not all of them. Now how to achieve this in a best way?? -
Raw queries in Django - empty response, but shouldn't be?
I wonder if you can help me - I have obviously done something wrong in the below, but I can't figure out quite what it is. In this, the API key gets passed as a URL parameter. I then select all records from the table voxi_skills, where the username is equal to the username in voxi_apikeys (and the key matches that in the request). The key is correct and the user exists in both tables, but it's returning an empty response. The URL path is: path('api/skills_data/<str:api_key>', views.get_skills)] Have I made a mistake in the syntax that would cause this? Thanks! def get_skills(request, api_key): if request.method == 'GET': try: api_key = str(api_key) names = ('id', 'status', 'skill_name', 'creator', 'target_date', 'points') query =''' SELECT category as id, status, skill_name, creator, target_date, points FROM voxi_skills where creator = (select user from voxi_apikeys where key = %s) ''' response = serializers.serialize('json', skills.objects.raw(query, [api_key]), fields=names) except: response = json.dumps([{ 'Error': 'Not a valid API key'}]) return HttpResponse(response, content_type='text/json') -

Django Admin - change user type (is_staff = T/F) based on group assignment
I have a django app with 3 types of user, super_user, admin, user. From django-admin panel I am assigning a user to Admin group. Admin group is a group with allowed permission.

Code and render dictionary list - each key is element of a set, value is difference between two sets
The example below perfectly articulates my problem. My models are: person id name 1 Alf 2 Beauty fruit id name 1 apple 2 banana 3 cape gooseberry 4 date 5 eggplant diet id person fruit 1 Alf apple 2 Beauty apple 3 Alf banana 4 Beauty cape gooseberry 5 Alf date 6 Beauty eggplant 7 Alf eggplant 8 Alf apple 9 Beauty apple 10 Alf banana 11 Beauty cape gooseberry (Of course, the person and fruit in the Diet model are actually foreign keys in the background.) Required Any of the people did not have the full fruit diet? If so, output = dictionary list, the respective key/values pairs being such person and the missing fruit from his/her diet If not, output = "None" My thinking persons = set(Person.objects.values_list('name', flat=True).order_by('name')) available_fruit = set(Fruit.objects.values_list('name', flat=True).order_by('name')) fruit_in_diet = set(Diet.objects.filter(person_id=1).values_list('fruit_id', flat=True).order_by('fruit_id')) missing_fruit = available_fruit - fruit_in_diet Done Tested my thinking and it works, for both persons respectively - that is, individually. It works only in so far as I get a set consisting of the correct missing_fruits for each person used in the code. My questions How do I get a dictionary list as output?

Strange Error When Checking If Object Exists
Thanks ahead of time for the help. I am trying to check if a cart object exists when a user visits the "myCart" page. If it does not, it should then create a new instance and use the user's id as a foreign key for reverse lookup. So I used the exists() method in an if statement. What's weird is that instead of executing the else block, it just throws me an error telling me the object doesn't exist. The test user doesn't have a cart object associated with it yet and that's obvious. What I don't understand is why it isn't triggering my else statement. Maybe I have been coding too long and need some sleep and that's why I'm missing it. Anyway if you guys could take a look for me I'd really appreciate it. :) The Error: Weird Error #the views.py file for this app: def myCart(request): context = {} if request.user.is_authenticated: owner = request.user.id if Cart.objects.get(cart_owner=owner).exists(): context['cart'] = cart return render(request, 'cart/myCart.html', context) else: cart = Cart(cart_owner=owner) context['cart'] = cart return render(request, 'cart/myCart.html', context) else: return HttpResponseRedirect(reverse("login")) def update_cart(request): if request.user.is_authenticated: owner = request.user.id cart = Cart.objects.get(cart_owner=owner) productID = request.GET['id'] product = Product.objects.get(pk=productID) if not product … -

I implemented a modification of the to_representation method of a serializer in order to flatten a nested relation through class LocalBaseSerializer(serializers.ModelSerializer): """Helper serializer flatenning the data coming from General Information.""" general_information = GeneralInformationSerializer(read_only=True) class Meta: abstract = True model = None exclude = ("id", "created_at") def to_representation(self, instance): data = super().to_representation(instance) general_information = data.pop("general_information") _ = general_information.pop("id") return {**general_information, **data} class ContractReadSerializer(LocalBaseSerializer, serializers.ModelSerializer): class Meta: model = Contract exclude = ("created_at",) It works as expected but, up to now, I did not manage to have the correct schema as shown from the extract below ContractRead: type: object description: |- Helper serializer flatenning the data coming from General Information. properties: id: type: integer readOnly: true general_information: allOf: - $ref: '#/components/schemas/GeneralInformation' readOnly: true beginning_of_the_contracts: type: string format: date termination_of_the_contracts: type: string format: date required: - beginning_of_the_contracts - general_information - id - termination_of_the_contracts I did not find any help neither in DRF documentation nor in drf-spectacular one. Thanks in advance for any help. -
is there any way to call a function(in another python file) and get the same return in Django view
I am trying to get a return from a function that is in similarity.py (function name returnTablewithURL) to Views.py. When I print the variable df in similarity.py it gives the output in dataframe. Like this: Similarity (%) https://en.wikipedia.org/wiki/The_quick_brown_f... 0.876818 https://knowyourphrase.com/the-quick-brown-fox 2.371295 I want to get the same output for fileupload function in views.py. So I tried to call the function from views (meaning from fileupload function) but it shows something in numbers. Output( with the help of print statement to check if it is same): <function returnTableWithURL at 0x000001D3631311F0> I have tried some other methods but in vain. It would be really helpful if i could use some suggestion and help Views.py: def fileupload(request): # Handel file upload if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): #Process for handeling the file snd store it on mongodb newdoc = Document(docfile = request.FILES['docfile']) #Contain process for extracting data in a file and storing them in DB as textfield newdoc.fileData = request.FILES['docfile'].read() newdoc.username = request.user newdoc.save() # Redirect to the document list after post result(newdoc.fileData) # Here i am trying to get the result from # returnTableWithURL function. This function is in # another python dframe = returnTableWithURL print(dframe) return render(request, …
