Create Razorpay Order in my Django DRF project gives 401 Error. "Authentication credentials were not provided."
Im trying to create a view where we create an order through razorpay, but continuously getting 401 error despite the keyId and KeySecret being correct. Even postman and curl gives the same error. I have tried removing the authentication, adding authentication through postman etc, but the issue persists. The Key works for razorpay's global API correctly, but the error is only in my function. Any help would be welcome thanks curl -X POST -H "Content-Type: application/json" -H "Authorization: Basic cnpwX3Rlc3RfNGZTSXNRaWdoeTZnU3o6Y1pZT3pvbnRWOFlEM1V1bzFneVlYalVF" -d "{\"amount\": 10000, \"currency\": \"INR\", \"receipt\": \"order_receipt\"}" http://127.0.0.1:8000/api/orders/create-razorpay-order/ {"detail":"Authentication credentials were not provided."} path('create-razorpay-order/', views.create_razorpay_order, name="create_razorpay_order"), def create_razorpay_order(request): razorpay_key = 'KEYID' razorpay_secret = 'RAZORPAYKEYSECRET' # Concatenating the API key and secret with a colon key_id_secret = f'{razorpay_key}:{razorpay_secret}' # Base64 encode the concatenated string base64_encoded_key_id_secret = base64.b64encode(key_id_secret.encode()).decode() # Endpoint for creating an order on Razorpay's server razorpay_order_url = 'https://api.razorpay.com/v1/orders' # Amount in paise (e.g., 10000 represents ₹100.00) amount = 10000 # Data to be sent in the request body data = { 'amount': amount, 'currency': 'INR', # Currency code (e.g., INR for Indian Rupees) 'receipt': 'order_receipt1', # Unique identifier for the order (optional) } # Headers for the request headers = { 'Content-Type': 'application/json', 'Authorization': f'Basic {base64_encoded_key_id_secret}', } # Make a … -
Django render a view depending geolocation from the browser
I'm trying to load my home page according to the geolocation given by the browser, if the coordinates are ok, I load a list of airports around these coordinates, otherwise I load all airports. However, I can't manage this between GET & POST requests. Each time I get all the airports in the page. In fact when the view is loaded (by the GET request) all airport are displayed, after when the page is entirely loaded the POST event is raised with the GPS information. So the list of airports around location is performed but the rendering is always wrong. urls.py urlpatterns = [ path('admin/', admin.site.urls), path('',views.home_view), views.py def home_view(request): 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') if request.method == 'POST': Latitude = float(request.POST.get('latitude')) Longitude = float(request.POST.get('longitude')) context = aviationweatherapi.getStationInfo(Latitude,Longitude) print ("Get airports list around current GPS location") else: #The request is GET context = aviationweatherapi.getStationInfo(None, None) print ("Get all airports") context.update({'IP':ip}) return render(request,'acceuil.html',context) template_Base.html (base of the acceuil.html) <body> {% csrf_token %} {% block contenu %} {% endblock %} <script src="https://code.jquery.com/jquery-3.6.0.js"></script> <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.js"></script> <script> const findLoc = () => { const success = (position) => { const latitude = position.coords.latitude; const longitude = position.coords.longitude; … -
How to set custom JWT in django using dj-rest-auth
I have setup a backend JWT authentication system using django, dj-rest-auth and simpleJWT. Currently, the dj-rest-auth is setting default JWT in the response cookies. To use custom cookies, I have to use simpleJWT's /token and /token/refresh urls. So, while testing in postman or swagger, I'm not getting the custom JWTs neither in the response body nor in the cookies(except the default ones provided by dj-rest-auth). Is there a way around so that I can receive those custom JWTs as cookies or response body? I am also using social authentication so those tokens have to be present in the response JWTs as well. My urls.py file urlpatterns = [ path('', include(router.urls)), path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), path('users/', include('dj_rest_auth.urls')), path('users/registration/', CustomRegisterView.as_view(), name='custom_rest_register'), ] serializer.py class EnrichedTokenPairSerializer(TokenObtainPairSerializer): @classmethod def get_token(cls, user): token = super().get_token(user) // custom token logic return token` I am using Django>=5.0.2 django-allauth>=0.61.1 djangorestframework>=3.14.0 djangorestframework-simplejwt>=5.2.2 dj-rest-auth>=5.0.2 Any suggestions would be helpful. I have done the authentication using dj-rest-auth and simpleJWT. I have a custom token serializer function to create custom tokens which return from /token url of simpleJWT. But while loggin in through Postman, these custom tokens were not present. I want them to be sent from the server either … -

Django Ñ problem? ValueError: source code string cannot contain null bytes
I'm working on Django and connecting to a remote SQL Server database. I managed to make the connection to the database using the MSSQL engine, but when I run inspectdb, the generated file contains errors due to the character "Ñ", in the file they appear as ±. So when I try to run the server, I get the following error: ValueError: source code string cannot contain null bytes. refering to the generated file with inspectdb I suspect that the problem is related to the database encoded in Modern_Spanish_CI_AS and also Ñ character is causing trouble. So far, I've tried the following: In settings.py, in database options: 'unicode_results': True Also, 'extra_params': 'ClientCharset=utf8' Modifying in base.py: mssql: unicode_results = options.get('unicode_results', True) Some less elegant solutions like opening the generated file with Notepad and saving it in UTF-8 or ISO 8859-1 -

Can I add the controller part of the MVC pattern to the MTV pattern in Django?
I'm trying to develop a multiplayer web game using Django. I understand that in Django's MTV Pattern, the view part takes on the role of the controller. But the view part needs a user in the frontend who accesses the website in order to be able to carry out actions. But in my WebGame there are also actions that need to be executed in the background, which need to be executed at certain times without any user in the frontend. So can I insert a folder in my Django code with the controller classes and specify when which function should be executed regularly? If I'm on the wrong path when it comes to solving my problem, I'm of course also interested in alternative suggestions. I watched a few videos and read a few books, but I couldn't find anything that really matched my problem. -

Passing information from view to form with FormWizard

How to know if the syntax of my urls is a valid django url syntax?
I generate my URLs dynamically and I want to know if there is a way to check if the syntax is valid or not. Because I'll create my URL from the Django admin panel, and if the syntax isn't correct for Django, the code will crash. For example, if I make a mistake and create a URL like this: test/<:custom_pk>/`, the app will crash, and I won't be able to modify it from the admin panel because of the crash.

In django how can I resolve a reverse error when copying text from an html table row and attempting to write it to a text file?
I have a django app with a page that shows a data table of text strings populated from a model. Each string is a website url.

Why do I get a server side HTTP 400 error when I try to access my django server with my mobile phone?
I have set up a simple, local running django server which provides buttons to trigger some bash commands on the server (currently my MacBook Pro).

I also tried with the Brave Browser installed on my Desktop PC - works fine. Now, as I try to access the website from my iPhone, a connection is established, the buttons are working and also, the text on the buttons disappeared.

Why is Django randomly deleting images from my template for no reason
Django never ceases to baffle me with completely uncalled for actions. I I have a media article template which is derived from a Django model. All works a treat and looks awesome, except for the images. One minute they're present, the next Django needs a new glasses prescription as it suddenly decides it can't see the image which is blatantly in the directory with which I have set up. Here's my full reproduceable example and see if anyone can figure out why Django decides its not going to show the image: #models.py from django.db import models import uuid # Create your models here. .... uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) article_image = models.ImageField(upload_to='media/assets') .... In my views.py, I have the following: def details(request, uuid): articles = MediaModule.objects.all().values() article = get_object_or_404(MediaModule, uuid=uuid) title = article.article_headline return render(request, 'media-article.html', {'article': article, 'title':title, 'articles':articles}) The file directory is as follows: Root| |- media |- template | - media-article.html |- media | - assets | - image.jpg #media-article.html <img src="{{article.article_image}}" alt="{{article.article_image}}"/> Just why does Django think "Ah-hah, there's the image!", and then says "Actually, I'm going to deliberate pretend the image is not there, because I am going to be difficult now" Why does it … -

I want to link the probe name to a details page that is in the overview app (overview/probe_details.html). The link works and shows the correct URL 127.0.0.1:8000/overview/probe_detail/1 but I get TemplateDoesNotExist error since django searches for all/probe_detail.html. project/urls.py urlpatterns = [ path('', include('home.urls')), path('all/', include('all.urls', namespace='all')), path('overview/', include('overview.urls', namespace='overview')), ] all/urls.py app_name = 'all' urlpatterns = [ path('probe_list', views.AllProbesView.as_view()), ] all/models/probe.py class Probe(Compound): targetName = models.CharField(max_length = 100, verbose_name="Target(s)") inVivoActivity = models.CharField(max_length=10, verbose_name="In vivo use"); mechanismOfAction = models.CharField(max_length = 255, verbose_name="Mechanism") def get_absolute_url(self): return reverse('overview:probe_detail', args=[str(self.id)]) def __str__(self): return f'{self.name}, {self.targetName}, {self.mechanismOfAction},{self.inVivoActivity}' class Meta: app_label = 'all' all/tables.py class AllProbesTable(tables.Table): name = tables.Column(linkify=True) class Meta: model = Probe template_name = "django_tables2/bootstrap5-responsive.html" sequence = ("targetName", "name", "mechanismOfAction" ,"inVivoActivity",) exclude = ("id",) all/views.py class AllProbesView(SingleTableView): model = Probe table_class = AllProbesTable queryset = Probe.objects.all() template_name = "all/probe_list.html" all/templates/all/probe_list.html {% load render_table from django_tables2 %} {% render_table table %} overview/urls.py app_name = 'overview' urlpatterns = [ path('probe_detail/<int:pk>', views.ProbeDetailView.as_view(), name="probe_detail"), ] overview/views.py (not ready … -
PostgreSQL: How to tag every table in my database? Generic Foreign Keys, array column, or other method
I'm currently designing a PostgreSQL database where I need to implement a tagging functionality. Essentially, any item from any table in my database can be tagged via key-value tags, very much like Azure tags. I'm considering different approaches for implementing this feature and I'm confused about the best approach: Using Django's Generic Foreign Keys: One approach I'm considering is leveraging Django's Generic Foreign Keys functionality to create a versatile "Tags" table that can reference any other table in the database. This allows flexibility and avoids complex logic. However, there might be drawbacks like performance implications or the database not making sense without Django's ORM. Manual Implementation in a single table, without Generic Foreign Keys: Another option is to implement the "Tags" table manually without relying on Django's Generic Foreign Keys. I would create a separate table that can reference any other table in the database, but without the use of formal foreign keys. This would require to either store some logic in the database or the backend, being more complex to maintain. Separate cross-reference tags table for each table: Alternatively, I could create a separate table (i.e. car_tags, house_tags, person_tags) for each table in my database that requires tagging. This …
