How can I migrate a Wordpress website to Django
I currently have a fully functional Wordpress website that is mostly static. It is a marketing website that mainly displays static webpages.

DRF: Updating a model in another models serializer or view
so I have a User and schools model which are related as an Owens(ManyToMany), student, and staff, if an owner registers and creates a school, I would like to perform a partial update to the Owens field of the request.user from having a null/blank or previously created schools to adding the newly created school serializers.py class SchoolSerializerBase(serializers.ModelSerializer): ... class Meta: model = School fields = ... def validate(self, attrs): ... return attrs def create(self, validated_data): instance = School.objects.create( ... ) instance.save() return instance and i have a simple view for it class CreateSchoolView(generics.CreateAPIView): queryset = School.objects.all() permission_classes = [IsSchoolOwner, ] serializer_class = SchoolSerializerBase My question: how do I update the request.user.ownes field and add the school instance to it?? -
django.db.utils.IntegrityError: The row in table 'main_page_projects' with primary key '1' has an invalid foreign key
Created first project model and populated it with some data, then tried to add profile model to it (no data there) through foreign key and while trying to do a migration for linking profile model with projects model getting an error: django.db.utils.IntegrityError: The row in table 'main_page_projects' with primary key '1' has an invalid foreign key: main_page_projects.profile_id contains a value '1' that does not have a corresponding value in main_page_profile.id. Value nr 1 was picked during the makemigration: It is impossible to add a non-nullable field 'profile' to projects without specifying a default. This is because the database needs something to populate existing rows. Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit and manually define a default value in models.py. I googled around and looked also stackoverflow, probably if I delete migration files and sqlite3 database then migrations should work, but I would like to know how to make it to work without deleting migration files and database. If populate profile then migration also works, but why it won't create a link with default values? What should I do differently or where … -
Django Image not showing up in django when using template tags

How To Decrypt Content In The Backend Then Pass It To The Frontend With Other Attributes
I'm building a Django social media, that focuses on privacy and anonymity, and I'm trying to build E2EE functionality, but I can't add any JavaScript in the project, so the decryption of the messages, notes is done locally and is stored in a temporary method like a dictionary or a list, then passed to the frontend, my problem is how to pass other attributes to the frontend? like messages are made like this: class Message(models.Model): id = models.UUIDField(primary_key = True, default = uuid.uuid4, editable = False) msg = models.BinaryField(null=False, blank=False) date = models.DateTimeField(default=timezone.now) to = models.ForeignKey(User, related_name='received', on_delete=models.CASCADE, blank=False, null=False) res = models.CharField(max_length=5, blank=False, null=False) author = models.ForeignKey(User, blank=False, null=False, related_name='sent', on_delete=models.CASCADE) so the msg that is the content of every message is the encrypted field, and when the messages view is loaded the messages are decrypted with the users private key class messages(LoginRequiredMixin, View): def get(self, request, touser, *args, **kwargs): if User.objects.filter(username=touser).exists(): user = User.objects.get(username=touser) msgs = Message.objects.filter(Q(to=request.user)|Q(author=request.user)) try: key = request.COOKIES['key'] except: return redirect('set-key') private_key = serialization.load_pem_private_key(request.user.profile.privatekey, password=key.encode('utf-8'),) messagescontent = [] for mess in msgs: plaintext = private_key.decrypt(mess.msg, padding.OAEP(mgf=padding.MGF1(algorithm=hashes.SHA256()), algorithm=hashes.SHA256(), label=None)) messagescontent.append(plaintext.decode()) context = {'msgs': messagescontent,} else: messages.warning(request, 'User Doesn\'t Exist') return redirect('messages-list') return render(request, 'posts/messages.html', context) so … -

Django loading data from fixture fails after schema migration
I have recently came across a problem while trying to reload fixtures to my database after a schema migration. I applied a schema migration which added a new field to my model. The database schema is indeed updated with the new field. However I can't reload fixtures: python manage.py loaddata data.json gives the following error "django.db.utils.OperationalError: Problem installing fixture '/../data.json': Could not load app.CheckupType(pk=1): no such column: name_de" The file data.json contains the same existing data in the database with the new field name_de. When I check the SQL database (or with python manage.py inspectdb), the field name_de exists. But when I run python manage.py dumpdata, there is no such field name_de. I tried to manually add the missing field in python manage.py shell, but I get the following error : "OperationalError: no such column: app_checkuptype.name_de" How can I synchronize my database model to my django model to have my fixtures updated with my new field? I tested the same procedure on another machine and it runs without any issues... -

Django convert external API data into a queryset without actually interacting with local database

Django ORM join a Raw Query
I want to join a fairly complex subquery to a Django ORM queryset: The resulting query should be like: select id from webshop_product left outer join ( select product_id, count(extra_col) as quantity from ( select product_id, col1 as extra_col from xyz where x = 123 and y = 456 union select product_id, col2 as extra_col from abc where a = 234 and y = 534 ) as t1 ) as t2 on t2.product_id = webshop_product.id The subquery in the left outer join clause is quite complex, it involves aggregating from a union from different tables, and I can not write it in the ORM. I tried writing it in the ORM, but I could not achieve the UNION on different tables.... so I want to join it as raw subquery, and annotate the quantity column. Something like: Product.objects.all().join("my complex raw subquery") Is this possible in the Django ORM? -

Django how to include all columns from one table, but a only subset of columns in a different table, using tbl.only?
I want to join a child table to the parent table, and return all columns from the child table (child.*), but only specific columns from a parent table (parent.foo, parent.bar), using only but not defer. Is there any syntax to issue a SQL similar to the following: select child.*, parent.foo, parent.bar from child join parent on child.parent_id = parent.id I do not want to use defer, because the parent table has even more columns than the child table. I currently have to spell out every column that I want using only: Child.objects.select_related('parent').only( 'id', 'name', 'creation_date', 'parent__foo', 'parent__bar' ).all() But I would like to include all the columns from Child. -
How to make view that uses a web scraper load faster

filtering annotated-aggregated columns with django_filters
Assume I have a Customer Model which is related to an Order Model. I want to list customers and the Sum(or Count) of their orders between a date range. if there was no order in the given range for any customer the annotated column would be 0. if I use django_filters FilterSet it changes the main WHERE clause of the query so the row with no order wouldn't be displayed, but I want something like: .annotate( order_count=Count( 'customer_orders', filter=Q( customer_orders__create_time__gte=query_params.get('order_after') ) & Q( customer_orders__create_time__lte=query_params.get('order_before') ) ) ) is there a neat way to achieve this using django_filters FilterSet? -
Django serializer.is_valid() makes a call to different custom serializer method
I have a django test server. i want to POST user data and return Response with 'username' and 'Token' after successfull registration. In the following view, I also check if request.data['email'] already exists in Users model because i want it to behave as unique=True and it gives me unexpected results. I know this code is just a noob implementation all around and it doesnt bother me for now, but the more important thing for me is to understand WHY my code is giving these results. I believe a detailed answer will help me understand python so much better. Here is the View function inside views.py : @api_view(['POST']) @permission_classes((AllowAny,)) def Register(request): r={"username": "JohnDoeyy", "password": "Thisisapassword60!", "email": "test@test.com", "age": "50"} #r = request.data if not (r.get("username") and r.get("password") and r.get("email")): return Response("empty fields") serializer = UserSerializer(data=r) print("debug1") if request.method == 'POST': print("debug2") if serializer.is_valid() and serializer.validate_email(r.get("email")): #User.objects.filter(email=r.get("email")).exists(): print("is_valid:", serializer.is_valid()) try: print("debug3 before .save") serializer.save() #This does NOT work. print("debug3 after .save") token, created = Token.objects.get_or_create(user=serializer.instance) return Response({"user": serializer.validated_data['username'], "token": token.key}, status=status.HTTP_200_OK) except Exception as e: print("debugException" , e) return Response(str(e)) else: print("3") return Response("fail") Here is the serializer.py . Possible culprit the validate_email method. class UserSerializer(serializers.ModelSerializer): password = serializers.CharField(write_only=True) def create(self, validated_data): … -
Django: Can't set up custom django User model
I want to set up my own django User model because I need additional fields, but I am getting the error. I read a lot of posts but I didn't find solution. What is the problem?

skip an iteration of the for loop in python
I need a hand, I don't understand how to fix it. Look at the photo to better understand my speech, where the new field is populated the value of new is subtracted from the total and I don't want it to be subtracted immediately but the next round. How can I do? def UserAndamentoListView(request): giorni = [] mese = [] new_user = [] tot_user = [] tot = User.objects.all().count() for day in range(5): giorni.append(datetime.datetime.now() - datetime.timedelta(days=day)) new = User.objects.filter(date_joined__contains = giorni[day].date()) new_user.append(new) tot -= new.count() tot_user.append(tot) context = {'giorni': giorni, 'new_user':new_user, 'tot_user': tot_user} return render(request, 'andamento.html', context) -
Can't see the address when nginx processes the port and outputs 502 Bad Gateway
I encountered a problem when learning nginx. I have 2 servers on 2 different ports. I want a page with information stored on port 8000 to be returned when accessing "http://localhost/api/v1/clients/". Now I get error 502 Bad Gateway.
