Python django model not pulling the table name, returning the project name instead
I have created both a django and a python project directory structure is analysis db_router models settings urls wsgi settings compareTemplates apps models tests utils views My model looks like this class Plans(models.Model): PROJECT_NAME = models.TextField() class Meta: db_table = 'schema.table' # specify the schema and table name managed = False # Prevent Django from managing the table schema def __str__(self): return self.PROJECT_NAME I have the database set up properly in the settings file and I am trying to see if my model can connect to it I ran: python manage.py shell from compareTemplate.models import Plans print(Plans._meta.db_table) the value returned is "compareTemplate_plans" I was not expecting that, I was looking for "schema.Table" This is my first real app in django, but I cannot figure out why the result is the project name.

Adding inlines to existing User model changes User admin pages
I have Domain model with a many-to-many user field to the existing User model. I want a Domain select field when I Add or Change a User on these User Admin pages. I used admin.TabularInline to achive this. The attached images show how changed the Add page after add inlines to the code. The minimal fieldset extended to a full fieldset what Django uses when someone edits an existing user, and the fieldsets completely mixed compared to the original page without inlines. Original Add User page The changed Add User page This is the actual code I tried, and the image above shows the working inlines with the Domain field, but I don't want to change the rest of the page. I'm satisfied with the existing Django User model and templates, I don't want a Custom User model and templates either, if I can avoid that. # model.py from django.db import models from django.contrib.auth.models import User from django.utils.translation import gettext as _ class Domain(models.Model): domain = models.CharField(_('Domain name'), max_length=100) master_dns_server = models.CharField(_('Master DNS server'), max_length=100, blank=True, default='') updatekey_secret = models.CharField(_('Key'), max_length=255, blank=True, default='') updatekey_name = models.CharField(_('Key name'), max_length=50, blank=True, default='') updatekey_algorythm = models.CharField(_('Key algorythm'), max_length=50, blank=True, default='') last_transfer = models.DateTimeField(_('Last … -

Large file download fails on slow network using HTTP/2 and AWS ALB
Given the following architecture: client <-> AWS ALB <-> uwsgi <-> Django The client fails to download a 12MB file when using HTTP/2 (the default), but works using HTTP/1.1. The file is streamed through Django for authentication purposes (it's fetched from a third party service). Here is an example of failure (I'm using a Socks proxy to limit bandwidth): $ curl -x socks5://localhost:1080 https://example.com/file.pdf --output "file.pdf" % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 79 12.6M 79 10.0M 0 0 61254 0 0:03:36 0:02:51 0:00:45 64422 curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1) However the same command with the flag --http1.1 works fine. This fails when I limit downloads to 512kbps - it works at 1024Kbps. I've not looked for the sweet spot, it's not important.

Django Authentication Timeout Error (H12) on Heroku with MongoDB Atlas
I have a question regarding an issue I'm facing. I built an authentication system in Django and connected it to a MongoDB Atlas database. The website is deployed on Heroku, but I'm encountering a timeout error on Heroku (Error H12). I've already checked the database connection, and it seems to be working. I also changed the timeout duration to 60 and 120 seconds, but neither resolved the issue. What could be causing this error? ERROR MESSAGE : heroku[router]: at=error code=H12 desc="Request timeout" method=GET path="/" host=XXXX (i changed my host name).herokuapp.com request_id=3f41-4c44-8740-a56e6191eb53 fwd="xx.xx.xx.xxx" dyno=web.1 connect=1ms service=30000ms status=503 bytes=0 protocol=https I checked the MongoDB Atlas connection, and it appears to be working fine. I also adjusted the timeout settings, increasing the timeout to 60 and 120 seconds, hoping this would resolve the H12 error on Heroku. However, I was expecting the website to load properly without timing out, but the issue persists despite these changes. -
How can I obtain Session Variables if the sessions change after an api call?
I am going through an official example of how to implement Oauth2 for using the quickbooks API. I am having trouble getting the state_token from the session variables within the callback view. Whenever I ise the oauth view it sends an authorization request to the quickbooks server. The request gives me a state token and a url to use to get an authorization code to use other APIs in quickbooks. I was able to print the state token in the oauth view by just printing "request.session['state']". This lets me now that it is being saved in the session. So when I redirect to the given url, Quickbooks sends me a code with the same state_token it gave me using the callback view in this example. The callback endpoint is requested by the Quickbooks server for validation purposes to make sure the state_token given back and the state_token in the session are the same, otherwise it'll return an error. This callback endpoint was given by me to Quickbooks website. But whenever I try and retreive the state_token within the callback view, it is always null/None. So whenever the callback view checks if the state tokens are the same in state_tok != … -

Django change on_delete at runtime
Story I am making a Jurnal app. Currently working on synchronization across multiple machines. I want to synchronize model by model, not the whole database at once. I even allow synchronization of just a few entries, image: The current problem I am facing is replacing the data of a model with the new synchronized data. I have the new database for the model (not all models) in JSON. Other models have ForeginKey to the data being changed (with on_delete=CASCADE). I have a mapping as a dict {old_pk : new_pk...}. I will use that to update other objects ForeginKeys to the objects being synchronized (whose pks will change). Problem I want to delete the old database without CASCADEing the deletion. I would like to set on_delete to DO_NOTHING temporarily until I finish the migration. Note: ReadAt code contains: read_by = models.ForeignKey( Person, on_delete=models.CASCADE, # change temporarily to DO_NOTHING at runtime ) By changing on_delete at runtime I could do: # DELETE OLD DATA ReadAt.on_delete=DO_NOTHING # pseudo code I want to achieve Person.objects.all().delete() # without code above, this deletes all ReadAt # LOAD NEW DATA with open("person_file.json", mode="w+", encoding="utf-8") as myfile: myfile.write(json.dumps(data_new_server)) call_command("loaddata", "person_file.json") # Then fix the PKs of ReadAt with … -
Django Azure Web App receiving 'Bad Request (400)' when accessed via the custom domain but works with the Azure provide default domain
I am deploying a Django Azure Web App and have added a custom domain that I bought off GoDaddy to it. I have also bound an SSL certificate provided by Azure to it. When I access the website via the default Azure domain, I'm able to access it but from the custom domain the server returns a 400 Bad Request. I've added to the list of CSRF_TRUSTED_ORIGINS as well as ALLOWED_HOSTS list the default domain as well as the custom domain. I have selected from the configuration on Azure Web App the option to redirect HTTP request to HTTPS. I have also added the DNS records (A and TXT) in GoDaddy to point to the server's public IP. May I have suggestions on things I could do to get it working? I am a novice at this and it's my first time setting up a website. I tried the following HTTPS settings in the settings.py file but it hasn't worked out, and I'm not too sure if I'm approaching it right either, thought I'd give it a go. SECURE_SSL_REDIRECT = True SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SECURE_BROWSER_XSS_FILTER = True SECURE_CONTENT_TYPE_NOSNIFF = True X_FRAME_OPTIONS = 'DENY' … -

Redirecting after making PUT request: can I redirect with GET request instead?
For my Django project, I have a primary model, Book, and an associated BookViewSet (from Django REST Framework). From the frontend, it's possible to edit other objects like Page, which POSTs to a corresponding PageViewSet. Changes to Page objects will also affect the Book, so I want to return an updated BookViewSet after processing changes to the Page. After processing a PUT request for the Page via the PageViewSet, I've tried leveraging the redirect shortcut to send the request to the BookViewSet, like this: return redirect('/books/10', pk=book_id) I expected (and hoped) this would make a GET request so that the backend would return an updated Book via the BookViewSet using the "retrieve" method. However, it seems like the BookViewSet still receives PUT request, which means the request will be sent to the BookViewSet's "update" method. Is this expected? If so, is there a way I can "get" an updated Book view after making changes to Page? I can achieve this by putting that logic into the BookViewSet's "update" method, but I already have that logic in the "retrieve" method and don't want to duplicate it. I recently found this pattern described as "post, redirect, get" and am not sure if … -

Django (s3) doesn't use custom domain for statics
I have S3 object storage with a CDN infront of it (on DigitalOcean). I have pointed my domain cdn.domain.com to the cdn & this is working fine. In Django I am using django-storages[s3] to connect with S3 and store static files. This works and static files are being transferred to my bucket on running collectstatic. Whenever I try to access any file the url doesn't get built properly. On localhost it looks like this http://127.0.0.1/http//cdn.domain.com.

Coda docs webhooks and django
I am building a web application with Django and I'm trying to automate the fetching of new data from Coda Docs. I want to use web hooks so that when rows are added on the Coda docs, my code for fetching the new data is executed. Already, I have a scheduled task that works, but I'd like to just switch to web hooks as it is automatic. I am confused on how to go about this. I don't understand what I'm reading online on Coda API regarding this. I don't even understand the step 1 and step 2 set up. I tried using match.com and despite providing my api key with read and write access it couldn't fetch the table.

Django Admin panel css not align
enter image description hereDjango admin CSS is not working as expected. As seen in the attached screenshot, the search box is misaligned. I need the search box to be properly aligned above the model data in the admin interface. Steps I've already tried: I have run collectstatic to make sure all static files are gathered. I cleared the cache to ensure no old files were affecting the layout. I verified that the custom CSS is correctly linked and applied, but the search box is still not aligning as needed. Details: Django version: 4.2.16 Issue: The search box appears out of alignment, and I want it to be positioned at the top, above the model data table. I would appreciate guidance on how to adjust the CSS or admin template to fix the alignment issue. -

Can you set permission classes per function in class-based views?
Let's say we have the following class-based view (CBV) implementing DRF's APIView: class ExampleListAPIView(APIView): permission_classes = [IsAuthenticatedOrReadOnly] def get(self, request): ''' List all examples ''' examples = Example.objects.all() serializer = ExampleListSerializer(examples, many=True) return Response(serializer.data, status.HTTP_200_OK) def post(self, request): ''' Create new example ''' serializer = ExampleListSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) Using permission_classes to set authentication policy in CBV, the policy is applied to all methods of class. Is it possible to set permission per function in a CBV, e.g. class ExampleListAPIView(APIView): def get(self, request): # Apply [AllowAny] # logic def post(self, request): # Apply [IsAuthenticated] # logic Or you have to use function-based views to achieve this behavior?
