Python Django / Keycloak / KeycloakOpenID / Login to my Django app with Keycloak
I am trying to connect my Django app to Keycloak and retrieve a token through the Keycloak API. I have tested the process first using Postman, and everything works perfectly; I receive a 200 status code. However, when I try to implement this in my Django app, I only get a 200 status code if I use hardcoded variables. When I attempt to use variables passed from a POST form, I receive a 401 Unauthorized error. What am I doing wrong? Postman everything works perfectly; I receive a 200 status code. POSTMAN REQUEST Python Django code : def get_token(self, username: str, password: str): # username = "admin@exemple.com" # password = "admin" try: token = self.get_keycloak_oidc().token( username=username, password=password, grant_type="password", ) self.token = token log.error("Successfully obtained token.") return self.token except KeycloakAuthenticationError as e: log.error(f"Failed to authenticate: {e}") return None def get_keycloak_oidc(self) -> KeycloakOpenID: if not self._keycloak_oidc: self._init_keycloak_oidc() return self._keycloak_oidc def _init_keycloak_oidc(self): self._keycloak_oidc = KeycloakOpenID( server_url=self.url, client_id=self.client_id, realm_name=self.realm, client_secret_key=self.client_secret, ) HARDCODED = 200 STATUS PARAMS = 401 STATUS (there are both the same) Error : 401: b'{"error":"invalid_grant","error_description":"Invalid user credentials"}' -
Django Cron Job Error: "[Errno 98] Address Already in Use" When Using Spotify API with django-crontab
I am working on a Django project where I use a cron job to manage Spotify playlists using the Spotify API. The cron job is scheduled with django-crontab and is intended to add tracks to multiple Spotify playlists across different accounts. Problem: The cron job works fine up to a certain point, but I encounter the following error repeatedly: ERROR 2024-09-06 01:11:02,768 cron Error adding tracks: [Errno 98] Address already in use ERROR 2024-09-06 01:11:07,771 cron Error adding tracks: [Errno 98] Address already in use ERROR 2024-09-06 01:11:12,774 cron Error adding tracks: [Errno 98] Address already in use What I have tried: Environment: I am using Ubuntu with Django, django-crontab, and Spotipy (a Python client for the Spotify Web API). Error Analysis: The error occurs after a log statement indicating that a user ID is being used to add tracks to a playlist. The next try block does not execute, and the [Errno 98] Address already in use error is raised. Port Conflict Check: I initially thought the error might be due to port conflicts with the Django server running on port 8000, but I understand that my Django server is expected to run on this port, so checking for … -

Django on IIS with FastCGI: HTTP Error 500.19 - Internal Server Error (Config Error 0x8007000d)
I'm trying to host a Django application on IIS using FastCGI. I've followed the steps to set up IIS with FastCGI and the wfastcgi.py handler for Django. However, I keep encountering an HTTP Error 500.19 - Internal Server Error with error code 0x8007000d.

Should I create more than one field with `document=True` and `user_template=True` for every model inside `search_indexes.py`?
So I have a general Haystack question here. They (haystack.readthedocs) say not to use document=True in the model you use in search_indexes.py file more than once. My question is, suppose I have 3 models that I will put into search_indexes.py, does that indicate that I have to have 3 fields with documenet=True and template=True in this file? If not, then does this mean that document=True and user_template=True can only be once regardless of the number of models? Here is the code for my search_indexes.py: from .models import ArboristCompany, ServicesType class ArboristCompany(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) company_name = indexes.CharField(model_attr='company_name') class ServicesType(indexes.SearchIndex, indexes.Indexable):``` I would like to add more fields with `document=True` and `user_template=True` for my other models in `search_indexes.py`, but kind of nervous about breaking something later on with my project involving this. -

Openlitespeed Django one click without php
I just moved to Openlitespeed Django, and I have my repo ready to be cloned, I have implemented Daphne to work smoothly with ASGI. The question is that: Can I use litespeed server without php? Openlitespeed Django one click is the fastest way to create a Django app, but for someone like me has the app ready and want to use Openlitespeed as a best alternative to Nginx and apache, I have setup everything I want and everything works smoothly, no access logs to view, no error logs to view, except for the 503 error service unavailable, and then i dig deeper into this, and found out that litespeed server is either waiting for php to be running or it's already built to work with php environment and Django will be under that environment. Again I have tried to check all the logs, access, error, debug, any clue, and nothing special, the only thing is that 503 service unavailable, Of course I have created a Daphne service file and I let Daphne to create a sock file for openlitespeed to communicate with. And all the permissions are set correctly, I tested how can openlitespeed user "nobody" can access that sock … -
How to upgrade django version of a project?
My project is running on Django 1.10 version. And I am using postgres as my DB. As Postgres has newer versions and older version is depricated, AWS is charging more for database support.

What to use when building a website in 2024? [closed]
What technologies should I consider using in 2024 to build a music-selling platform on top of Django? I've previously built a simple website using Django, HTML, JavaScript, SQLite, and CSS. Now, I’m planning a more advanced project: a music-selling platform. While I’m comfortable with the basics, I’m wondering what additional technologies I should explore in 2024 to enhance my project. Here are some specific areas where I’m looking for advice: Frontend frameworks: I’ve heard of tools like Next.js and Bootstrap, but I’m unsure whether they would significantly improve my project. Database: I used SQLite in my last project, but should I consider moving to PostgreSQL or another database for better performance and scalability? Authentication: I’ve previously implemented Django Allauth, but I’m curious if it remains a strong choice for authentication in 2024. Payment integration: What are the recommended tools for securely handling payment processing for digital goods like music? Performance and scalability: Any tips for improving the platform’s performance and scaling it effectively as it grows? Other tools or technologies: Are there any other useful libraries or technologies I should look into, especially for e-commerce functionality or media handling? I’d appreciate any suggestions on what additional tools, frameworks, or best … -

Need example of pytest test upload file to graphql

Django CSRF error with request on multiple tabs simultaneously
I am working on a Django project and have encountered an issue with CSRF tokens when rendering a page with a form. To reproduce the issue, I added a 5-second delay when rendering the page. Here is the scenario: I open the URL with the form in the first browser tab. Within 5 seconds, I open the same URL in a second tab, ensuring that the first request hasn't yet completed. As a result, the first tab generates a csrftoken, and the second tab overrides it. However, the csrfmiddlewaretoken in the form on the first tab remains bound to the old csrftoken. When I submit the form from the first tab, a CSRF error occurs due to the mismatch. Could you please help to fix this issue? Thanks in advance! -
Automatically create a free trial Stripe checkout
We use Stripe for our checkout and have a free trial enabled. So when a user comes to the site to enable the free trial they just enter their email in the checkout. What I would like is to tie the start of the free trial with creating an account on my site. Since I get the user's email with account creation I would like to create the free trial programmatically and remove that step. Is that possible? Here is my code to create the checkout session. def create_checkout_session(request, app_type): subscription_plan_duration = SubscriptionPlanDuration.objects.filter().first() user_subscription = UserSubscription.objects.create( subscription_plan_duration_id = subscription_plan_duration.id, user_id = request.user.id, app_type = app_type, is_active = False #True - change for 3. ) discount_coupon = DiscountCoupon.objects.filter(subscription_plan_duration_id = subscription_plan_duration.id).first() checkout_session = stripe.checkout.Session.create( line_items=[ { 'price': subscription_plan_duration.price_id, 'quantity': 1, }, ], metadata={ "user_subscription_id": user_subscription.id }, mode="subscription", # discounts=[{ # 'coupon': discount_coupon.coupon_id, # }], subscription_data={ "trial_period_days": 30, "trial_settings": { "end_behavior": { "missing_payment_method": "cancel" } } }, payment_method_collection="if_required", allow_promotion_codes=True, success_url=settings.APP_END_POINT + '/stripe/success', cancel_url=settings.APP_END_POINT + '/stripe/cancel-subscription/' + app_type ) return redirect(checkout_session.url) -
Heroku Postgres not working on Heroku Server [Django]
I have a Django project, where I am using Redis/Celery to call some API's. I've set up my settings.py file to connect to the Postgres database and when running the Django project locally (with Redis/Celery running locally) the data is stored in the database no problem. When I push the application to Heroku, the data doesn't save to the database. I'm not sure if this sounds like a problem with the code itself, or the settings of the server causing this (Redis/Celery on Heroku). I am using a Heroku Postgres Database.

request.session['some_variable'] TypeError: Object of type Decimal is not JSON serializable
I´m updating some code from Django 1.8 and python 2.7 to django 5.0 and python 3.11, in the old version in some functions are make session variables that store decimal values and after that make a redirect like this: request.sessions['decimal_var'] = 1.00 return HttpResponseRedirect('/somepage/') This works fine in the old version so the 'decimal_var' can be used in the redirected page, but in the new version (Django 5.0) if I pass any session variable with decimal value gives me this error: File "C:\Python311\Lib\json\__init__.py", line 238, in dumps **kw).encode(obj) ^^^^^^^^^^^ File "C:\Python311\Lib\json\encoder.py", line 200, in encode chunks = self.iterencode(o, _one_shot=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Python311\Lib\json\encoder.py", line 258, in iterencode return _iterencode(o, 0) ^^^^^^^^^^^^^^^^^ File "C:\Python311\Lib\json\encoder.py", line 180, in default raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type Decimal is not JSON serializable One option is just pass int or string values, but i think this is not a real solution and why the new versions can´t manage the decimal values and the old can, this could bring more problems if is a need to use decimal values.

Django Axes works, but doesn't store Access attempts nor failures
I apologize in advance, I am new to all of this (Stack, Django and Axes). I am creating a simple website where you can create users, and I implemented django axes.

Separate Django API and Django regular templates views
I'm starting a project which will have a website and a mobile app. I want these two to use the same backend, which I'll code in Django, specifically django-ninja. For the website front-end, I want to use Django also as I'm familiar with it already and I feel it suits my needs for this project. The question is: should I create 2 separate Django projects, one dedicated to the API, and one dedicated to the "Front-end", or have them both in the same project? -
