How to execute a multi-statement Snowflake SQL script (DECLARE, DDL, DML, CASE) from Python with parameters and fetch SELECT results?
I’m new to Python and Snowflake’s scripting blocks. I want to keep a multi-statement Snowflake SQL script in a .sql file and execute it from Python with parameters. The script may include DECLARE, DDL, DML, CASE logic — basically SP-like behavior — and I want to capture any SELECT result sets if present. Example script (simplified): BEGIN -- Declare a variable using Snowflake scripting DECLARE v_admin STRING DEFAULT :admin_user; -- Create a temporary table CREATE TEMP TABLE temp_data ( tenant STRING, client STRING, user_id STRING, use_mm STRING, access_level STRING ); -- Two inserts INSERT INTO temp_data (tenant, client, user_id, use_mm, access_level) VALUES ('101', '202', 'admin_user', 'true', NULL), ('102', '203', 'guest_user', 'false', NULL); -- CASE update using the declared variable UPDATE temp_data SET access_level = CASE WHEN use_mm = 'true' AND user_id = v_admin THEN 'full' WHEN use_mm = 'true' THEN 'limited' ELSE 'none' END; -- Return results SELECT * FROM temp_data; END; What I need: Execute the file from Python, bind parameters (e.g., admin_user), and support multiple statements. If the script contains one or more SELECTs, fetch results (ideally the last SELECT); otherwise just execute. Keep temp tables ephemeral (session-scoped). Questions: Can I achieve stored-procedure-like behavior by keeping the SQL … -

How to handle customer.subscription.created if a organization(tenant) doesn’t exist yet in Stripe webhook?

testing a complex multipart custom django form
I have 2 complex custom form classes; each class contain several subforms (model form, formset and sometimes nested formset). I have written tests for both of them : tests of the form methods (init, full_clean, is_valid) using post data. I am looking for a way to test the creation of the form with the renderer. In the view tests, using request factory, the form is created but the forms within the formset are not created. When I do manual testing of the form with the test server, I encounter some errors that are notcovered by my tests -

Why does my Django models.Manager return all objects on a relationship?
I don't particularly understand what's going on here, but it seems that super().get_queryset() doesn't do what I think it does? I have 1:N relationship, and the default FK reverse lookup works: >>> for thing in this.thing_set.all(): ... print(thing.this) Each one of these is This. However, with my customized: >>> for thing in this.thing_set.by_date(): ... print(thing.this) Will produced This and `That* class ThingByDateManager(models.Manager): def by_date(self): return super().get_queryset().order_by("start_time") That's all there is. class This(models.Model): name = models.CharField(max_length=255, primary_key=True) class Thing(models.Model): start_time = models.DateTimeFiled() name = models.CharField(max_length=255) this = models.ForeignKey(This, on_delete=models.CASCADE) objects = ThingByDateManager() (might not have those models perfectly written, but I'm hoping it's just something silly with the queryset or something) Why doesn't this correctly filter my objects by this, instead returning all of the Things? -

Stripe Subscription: latest_invoice.payment_intent raises AttributeError: payment_intent
I'm trying to create a subscription in Stripe using Python and the official library, with the goal of obtaining the client_secret from the initial invoice's PaymentIntent to complete payment on the frontend. Here is the code I'm using: import stripe stripe.api_key = 'sk_test_...' price_id = 'price_...' # Example subscription = stripe.Subscription.create( customer=customer.id, items=[{'price': price_id}], payment_behavior='default_incomplete', expand=['latest_invoice.payment_intent'], ) I want to access: subscription.latest_invoice.payment_intent.client_secret But I get the error: AttributeError: payment_intent What I've checked so far The subscription is created successfully. The parameter expand=['latest_invoice.payment_intent'] is included to embed the payment_intent object. I've verified that the invoice (latest_invoice) exists. However, the payment_intent field is missing from the latest_invoice object. Questions Why is payment_intent missing from latest_invoice when creating the subscription with payment_behavior='default_incomplete' and expanding the field? How should I obtain the client_secret to confirm payment on the frontend using Stripe.js in these cases? -

What's the best way to handle valueless attributes in Django templates?
I'm looking for a cleaner way to conditionally add valueless HTML attributes, like disabled, in a Django template. For example, in the code snippet below, the {% if %} tag is embedded directly inside the <button> tag, which I find makes the code harder to read. <button type="submit" id="prev-page-btn" class="btn btn-secondary w-50" name="prev-page-btn" {% if not page_obj.has_previous %}disabled{% endif %}> Previous </button> Is there a more elegant solution for this? I'd like to avoid duplicating the entire <button> block just to control the presence of the disabled attribute. -
'querystring' received too many positional arguments when passed a QueryDict
I'm using Django 5.2 and I can't get my head around the following issue: In my view, I have something like this: removal_qs = request.GET.copy() # contains teams=1&teams=2 removal_qs.setlist('teams', [1]) Debugging shows: In [3]: type(removal_qs) Out[3]: django.http.request.QueryDict But when I try to use this with the {% querystring %} tag in a template, like so <a href="{{ request.path }}{% querystring qs %}">x</a> I get the error 'querystring' received too many positional arguments. The documentation for the querystring template tag specifically says that This tag requires a QueryDict instance, which defaults to request.GET if none is provided. So where am I doing this wrong? -

Hello I'm on a fullstack course with the Code Instiute and both me and technical support have been stumped on this issiue: After deploying on Heroku no css or js loads or runs. error from chrome inspect console log: turnpenny-fry-syndrome-98cd38841f84.herokuapp.com/:1 Refused to apply style from 'https://turnpenny-fry-syndrome-98cd38841f84.herokuapp.com/static/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. css is linked in html like so: <link rel="stylesheet" href="{% static 'css/style.css' %}"> settings file: STATIC_URL = "static/" STATICFILES_DIRS = [os.path.join(BASE_DIR, "static" ),] STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles") Relative file path of my css file: static\css\style.css And Debug is always set to False when deploying. Seemingly the error messages show the right path for the files both in vs code and on github, seems like now its Heroku not reading from github correctly??? Have grone through Django documentation: https://docs.djangoproject.com/en/4.2/ref/settings/#static-url https://docs.djangoproject.com/en/4.2/ref/contrib/staticfiles/#django-admin-findstatic both me and support staff on my course have many times checked my settings file, .python-verion file, base.html links and commented out js link so i can just focus on css first also, I checked config vars and they appear all correct. -
Is using Google Cloud Tasks to invoke an internal Django endpoint effectively asynchronous (even under WSGI)?
I'm running a Django application on Google Cloud Run using the default WSGI-based setup (e.g., Gunicorn/ runserver for local dev). To avoid blocking during long-running operations like third-party API calls, I'm planning to use Google Cloud Tasks. Current design: A request comes in to a Django endpoint (e.g., a webhook or ping from an external service) Instead of processing the request inline, I enqueue a Cloud Task That task posts to another Django endpoint within the same service, which performs the third-party API call using data passed in the task payload This means: I'm not offloading the work to a separate Cloud Run service The fetch logic is still part of the same Django service/container, just decoupled by the task My question: Does this setup allow the third-party call to be effectively asynchronous (i.e., non-blocking to the original request), despite using WSGI and not ASGI or Celery? When searching around, I mostly see articles and examples where Cloud Tasks are used to call a separate Cloud Run service, not another internal route in the same app. Is this internal invocation pattern valid and scalable under WSGI, or are there caveats I should be aware of? -
Django multi-app authentication: sharing custom token validation and permissions across separate codebases
I'm building a multi-platform system where I have one central authentication service (let's call it "Auth") and multiple other Django applications (App1, App2, App3) that need to authenticate users with custom tokens and permissions. Current Setup: Auth service: Handles user registration, login, token management App1, App2, App3: Separate Django projects with their own database and business logic All apps need to validate users authenticated through the Auth service Authentication Flow: User logs in through Auth service → receives token User makes requests to App1/App2/App3 with that token App1/App2/App3 need to validate the token and get user data Authentication Model: class AuthToken(models.Model): token = models.CharField(max_length=48, unique=True) user = models.ForeignKey(User, on_delete=models.CASCADE) platform = models.ForeignKey(Platform, on_delete=models.CASCADE) expires_at = models.DateTimeField(null=True, blank=True) is_revoked = models.BooleanField(default=False) # other fields (ip, device_id, device_name, etc...) Token Configuration: Settings.py # settings.py REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'path.to.authentication.AuthTokenAuthentication', ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated', ], } Authentication Class # path/to/AuthTokenAuthentication.py class AuthTokenAuthentication(BaseAuthentication): """ Simple, clean AuthToken authentication. """ def authenticate(self, request): # Get Authorization header auth_header = request.META.get('HTTP_AUTHORIZATION') if not auth_header or not auth_header.startswith('Bearer '): return None # No token provided # rest of my code The Problem: App1, App2, App3 need to use the same custom AuthTokenAuthentication and permission classes, but … -
Refresh token being passed in response body in registration but not login in Django
I am using the Django REST Framework with dj-rest-auth and django-allauth for authentication and authorisation with JWTs. From what I have heard, using HTTP-only cookies to store the tokens is a secure approach where the access token is passed in the response body but the refresh token is passed to the browser as a cookie. The default login endpoint works this way, returning the access token in the response body and returning the access and refresh tokens as HTTP-only cookies as well as a csrftoken and sessionid. However, the signup endpoint doesn't exhibit the same behaviour, it returns both access and refresh tokens in the response body and returns neither as a cookie, but does return these cookies: messages, csrftoken, sessionid. Does anyone know why this might be happening and how I could get registration to behave the same way as login? Here are the relevant parts of my settings.py: REST_AUTH = { "USE_JWT": True, "JWT_AUTH_COOKIE": "access-tkk", "JWT_AUTH_REFRESH_COOKIE": "refresh-tkk", # "JWT_AUTH_SECURE": True, # Use secure cookies in production for HTTPS only "JWT_AUTH_HTTPONLY": True, # Secure HTTP-only cookies "REGISTER_SERIALIZER": "authentication.serializers.CustomRegisterSerializer", "USER_DETAILS_SERIALIZER": "authentication.serializers.CustomUserDetailsSerializer", } SIMPLE_JWT = { "ACCESS_TOKEN_LIFETIME": timedelta(minutes=15), # Short-lived access token "REFRESH_TOKEN_LIFETIME": timedelta(days=14), # Longer-lived refresh token "ROTATE_REFRESH_TOKENS": True, # … -

Is there a way to reduce polling woth django dramtiq
I have a webapp using django hosted on render cloud platform which allows users to make api call to deepseek. These api calls sometimes take 5 minutes to respond, and doing so with async may cause issues if user connection drops. So I planned to use a Dramatiq background worker hosted on a render service too seperate to the web app. I set up redis with upstash and connected to dramtiq and it turned out it was polling redis hundreds to thousand per minute which on upstash equates to commands which equates to a high cost. So my goal is to reduce the polling to once per minute to reduce my redis commands number to reduce costs. I have tried setting up gevent too but now sure how to reduce redis polling with dramtiq and also use gevent.
