When I run python manage.py test... only some of my tables / fields are created in the test db
In django, I am trying to run tests on a test db, but I can't seem to get the test db stood up properly... I have 226 models on my real db, but when I run python manage.py test (test location) it breaks pretty quickly referencing that a field is not present in the test db. psycopg2.errors.UndefinedColumn: column core_division.display_name does not exist A quick look at the test db (since it crashes, it doesn't teardown the db, so I can view it) shows only 47 tables created, and sure enough that particular field is not there. Below is my database settings in my config.settings.test file: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'myscore', 'USER': env('DEFAULT_DATABASE_USER'), 'PASSWORD': env('DEFAULT_DATABASE_PASSWORD'), 'HOST': 'localhost', 'PORT': '', 'TEST': { # 'MIRROR': 'default', 'SERIALIZE': False, # 'MIGRATE': False, } }, } What I tried to do as a workaround was apply the 'MIGRATE': False option. When I do this (with --keepdb applied), I see that the test db has 195 tables (and does have the field that wasn't created before). So this is better. No failures / crashes. However...I can't seem to write / read anything from the db and I'm not sure why... So...what I've … -
How to serialize request.user for ModelSerializer to auto fill the user field in Model?
This question is not good question but, I spent 6 hours to solve this problem, searching in stackoverflow and still problem is bother me. I have a model as below : class Product(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=144, primary_key=True, unique=True) description = models.CharField(max_length=144) def __str__(self) -> str: return self.title and its serializer : class ProductSerailizer(serializers.ModelSerializer): class Meta: model = Product fields = "__all__" exclude = ["user"] and my view is like below : class CreateProduct(generics.GenericAPIView): """""" serializer_class = [ProductSerailizer] permission_classes = [permissions.IsAuthenticated] def perform_create(self, serializer): return self.serializer(user=self.request.user) def post(self, request, *args, **kwargs): user_serializer = UserSerializer(data=request.data) if user_serializer.is_valid(): user_serializer.save() return response.Response(user_serializer.errors, status=status.HTTP_400_BAD_REQUEST) I wanna auto fill the user by the request, but when I send the request with postman it says : "username": [ "A user with that username already exists." ] and it doesn't save my instance.

How do I display non field errors and field errors after I hit the submit form button for user sign up?
I would like to display Form.non_field_errors() and Form.errors upon submitting my form. It has email, password and confirm password fields. The thing is, I want all errors to show up if the inputs for these fields are wrong. (e.g. invalid email, passwords don't match). However, I am facing the issue that upon submission of my form when all fields are wrong, only the non_field_errors() show up first. Once that has been resolved and I clicked enter again, the field errors then show up. I don't want them to show up 1 by 1 and prefer that they show up altogether. Issue on my form (Only Enter a valid email address is showing up, no password errors when there should be upon submitting) Here's my code. forms.py class UserRegistrationForm(forms.ModelForm): password2 = forms.CharField( label="New password confirmation", widget=forms.PasswordInput(attrs={"autocomplete": "new-password"}), ) class Meta: model = User fields = [ "email", "password", ] def _validate_passwords(self, password1, password2): password_errors = [] try: validate_password(password1, self.instance) except ValidationError as e: password_errors.append( ValidationError(_("Weak password provided"), code="weak-password"), ) if password1 and password2 and password1 != password2: password_errors.append( ValidationError(_("Passwords mismatch"), code="password-mismatch"), ) if len(password_errors) > 0: raise ValidationError(password_errors) def clean(self): cleaned_data = super().clean() email = cleaned_data.get("email") password1 = cleaned_data.get("password") password2 = … -
My Python Django button is not appearing when someone logs in(it should be)
I am working on a Python Django project. I'm currently working on a way for myself to log in and create a product card for this project store. The create button should only appear when I am logged in. It's just not appearing. I go to Inspect the web page and I don't even see the code for my button. I have no idea what is happening and some help would be awesome! This is the block of code that should be producing said button. If the user is authenticated, it'll create this create button under each one of my categories. I originally had the for statement over the if statement and I switched it to see if that would change anything and nothing happened. HTML {% if user.is_authenticated %} {% for category in categories %} <p>User is authenticated: {{ user.username }}</p> <!--LINE FOR DEBUGGING--> <p>Category: {{ category.name }}</p> <!--LINE FOR DEBUGGING--> <a class="create_button" href="{% url 'create_product' category.id %}">Create {{ category.name }}</a> {% endfor %} {% endif %} One of the first things I did I was add some debugging lines to see if it actually understood I was logged in.

Cookie on the same domain is set, but not being sent to another subdomain
I have a django server running on api.domain.lt and sveltekit server running on dev.domain.lt. Due to the separate servers I have a endpoint /csrf that forces to set a cookie if there's none for the frontend, so I could perform any kind of POST requests later. As I can see in the response headers the cookie is being set: Set-Cookie csrftoken=d8nimJM2fXtyPdhra2h8oF36o7juCJKz; Domain=.domain.lt; expires=Tue, 28 Jan 2025 17:35:19 GMT; Max-Age=31449600; Path=/; SameSite=Lax; Secure But when I perform another request to the server the cookie is not being added to the request,for god damn sakes, whyyyyyy? Even if I open the django server in another tab and view the Cookies in the dev tools, there's nothing. CORS_ALLOWED_ORIGINS = [ "https://domain.lt", "https://dev.domain.lt", "https://api.domain.lt", ] CSRF_TRUSTED_ORIGINS = [ "https://domain.lt", "https://dev.domain.lt", "https://api.domain.lt", ] # This allows us to send requests from dev.domain -> api.domain CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_SECURE = True # The cookie will be marked as “secure”, which means browsers may ensure that the cookie is only sent under an HTTPS SESSION_COOKIE_SECURE = True # Is this actually doing anything?

Python Django(?) ORM race conditions
The answer to my question may probably be obvious, but I'd like to find out for myself. I love Django ORM and use it in almost all my projects. I'm currently developing a telegram bot using Pyrogram (available in asynchronous mode with async await + asyncio.run), and I want to use Django ORM in it. Let me give a simplified example of my task. There is a button that is bound to an object in the database, each click of which should decrease a field in one object and increase another field in another, conditionally: obj1 = Object1.objects.get(id=X) if obj1.filed1 > 0: obj2 = Object2.objects.get(id=X2) obj1.field1 += N obj2.field2 += N obj1.save() obj2.save() However, I am worried that this may cause a race condition and the result of executing this code with several simultaneous button clicks may differ from what is expected (both in the if condition and when further saving objects). Please tell me what are the best practices for handling such tasks. Is select_for_update method would cover me needs? If Django ORM is not a good solution for this, what ORMs or database libraries should I look at? If Django ORM is suitable, what exactly is the best … -

Why is my get_token() not the same as my request.META.get("CSRF_COOKIE")?
Does anyone know why I am encountering this issue? I'm starting to test Angular 17 as a FrontEnd with Django as a Backend, and when validating a form, I encounter the issue that when obtaining my token from Django and sending it in the HTTP header, it doesn't match the token expected by Django. I'm not sure if the problem is that the expected token is not updating with get_token() or if get_token() is returning the incorrect token. settings.py: CSRF_TRUSTED_ORIGINS = [ "http://localhost:4200", ] CSRF_COOKIE_NAME = 'XSRF-TOKEN' CSRF_USE_SESSIONS = True CSRF_COOKIE_SECURE = True CSRF_COOKIE_HTTPONLY = True CSRF_COOKIE_DOMAIN = 'localhost' CSRF_COOKIE_PATH = '/' #En esta sección configuro el CORS CORS_ORIGIN_WHITELIST = [ "http://localhost:4200", ] CORS_ALLOWED_ORIGINS = [ "http://localhost:4200", # Angular ] CORS_ALLOW_CREDENTIALS = True CORS_ALLOW_METHODS = [ 'DELETE', 'GET', 'OPTIONS', 'PATCH', 'POST', 'PUT', ] CORS_ALLOW_HEADERS = [ 'accept', 'accept-encoding', 'authorization', 'content-type', 'dnt', 'origin', 'user-agent', 'x-csrftoken', 'X-XSRF-TOKEN', 'x-requested-with', 'Content-Type', '_HttpHeaders', ] csrf-service.service.ts export class CsrfService { private csrfToken: string | null = null; constructor(private http: HttpClient) {} //Obtener el token CSRF getCsrfToken(): string | null { return this.csrfToken; } //Cargar el token CSRF desde el servidor loadCsrfToken(): Observable<any> { const csrfUrl = 'http://localhost:8000/obt_csrf_token/'; return this.http.get<any>(csrfUrl); } //Actualizar el token CSRF en el … -
Django - Cannot Display Elements Based On Field Value
I’m currently building a gaming app where a currently logged in user has access to play different games based on their rank in our application. So if a currently logged in user has a rank of let’s say 100 than all the games with a game rank of 100 and below will be displayed. The rest of the games will be locked. I can’t get this currently fully to work with my code. What do I need to change with my code? If I test using When(game_rank__lte=25, then=Value(True)), that seems to work, I can see both locked and unlocked games based on the value of 25 and less. But when I do When(game_rank__lte=user_profile_rank, then=Value(True)), that doesn’t seem to work. All the games are unlocked and none are locked. The rank of each game is the game_rank field in the Game_Info model. The rank of the currently logged in user is the rank field in the User_Info model. Any help is gladly appreciated. Thanks! models.py class Game_Info(models.Model): id = models.IntegerField(primary_key=True, unique=True, blank=True, editable=False) game_title = models.CharField(max_length=100, null=True) game_rank = models.CharField(max_length=1000, null=True, blank=True) game_image = models.ImageField(default='default.png', upload_to='game_covers', null=True, blank=True) locked_game = models.BooleanField(default=0) unlocked_game = models.BooleanField(default=0) class User_Info(models.Model): id = models.IntegerField(primary_key=True, blank=True) image … -

How to set next_url in Middleware?
I'm writing a custom piece of Middleware for my Django project that will redirect every page request to an age gate if the user has not yet confirmed they are old enough to enter the page. I want the age gate page to redirect to their originally requested page when they have confirmed the age gate. My middleware right now looks as follows: from django.shortcuts import redirect class AgeGateMiddleware: EXCLUDED_URLS = ['/preview/agegate'] def __init__(self, get_response): self.get_response = get_response def __call__(self, request): if not request.session.get('agegate') and request.path not in self.EXCLUDED_URLS: request.session['next_url'] = request.path return redirect('/preview/agegate') response = self.get_response(request) return response And my age gate view looks like this: def age_gate_view(request): #Load the original page after checking age gate. next_url = request.session['next_url'] #Register users IP for age gate. x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') if x_forwarded_for: ip = x_forwarded_for.split(',')[0] else: ip = request.META.get('REMOTE_ADDR') try: ip =ip except: ip = 'none' form = AgeGateForm({'ip':ip}) #Store age gate response if request.method == 'POST': form = AgeGateForm(request.POST or None, {'ip':ip}) if form.is_valid(): form.save() request.session['agegate'] = 'welcome' return redirect(next_url) context = { 'form':form, } return render(request,'Academy/agegate.html', context) Right now the Middleware works as intended: It redirects to the age gate if this has not yet been confirmed.

How can i make ManyToMany admin pannel on django?

Dockerizing Django and Nginx - How can I Retrieve the Client IP Instead of the Bridge Network Gateway IP in Django with Docker?
I'm currently facing an issue with my Django application where, despite including the X-Real-IP and X-Forwarded-For headers in the request, I am still retrieving the gateway IP instead of the actual client IP.

I am making an app in Django and using the allauth library to enable Facebook login. I set up everything accordingly in my Django project and the FB Developer console (I am pretty sure of this because my Google login works), but when I click on the "Login with Facebook button", a popup window appears with a Facebook page asking me to login, but my app is already in the login cancelled page in the following URL: "https://www.xxxxxxxxxxxxxx.com/accounts/social/login/cancelled/". If I login in the popup window nothing changes in my app and the popup just closes. The weirdest thing is that I am not getting any error or warning logs. This happens both in development and production mode. I read in other posts that adding "ACCOUNT_DEFAULT_HTTP_PROTOCOL = 'https'" in settings.py can solve the issue, but it did not work for me. Has anyone had a similar problem and know the solution to this? -

How to re-implement Django Authentication middleware
Current 'django.contrib.auth.middleware.AuthenticationMiddleware', Is logging in the user and such but using different JWT token from different generated sources (ex apple google github) will not work with this one because it's accepting only and only the one from GRAPHQL_JWT = { "JWT_ALLOW_ANY_CLASSES": [ "graphql_auth.mutations.Register", "graphql_auth.mutations.ObtainJSONWebToken", ], "JWT_VERIFY_EXPIRATION": True, "JWT_LONG_RUNNING_REFRESH_TOKEN": True, "JWT_EXPIRATION_DELTA": timedelta(days=365), "JWT_REFRESH_EXPIRATION_DELTA": timedelta(days=365), } I've already implemented a custom middleware "CustomAuthenticationMiddleware" and It works fine but I need to remove the already existing auth middleware and I get this error django.core.management.base.SystemCheckError: SystemCheckError: System check identified some issues: ERRORS: ?: (admin.E408) 'django.contrib.auth.middleware.AuthenticationMiddleware' must be in MIDDLEWARE in order to use the admin application.
