How to make Django present generated mp4
I have a docker volume that contains generated mp4 files. I want to find a way to display them in dev because my current solution results in an error. error Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/fergana_api/files/36/movies/movie.mp4 Using the URLconf defined in fergana_api.urls, Django tried these URL patterns, in this order: admin/ api/schema/ [name='api-schema'] api/docs/ [name='api-docs'] api/ [name='all-runs'] tests/<slug:test_session_id> [name='single-run'] tests/<slug:test_session_id>/<slug:test_name> [name='single-test'] ^static/(?P<path>.*)$ ^files/(?P<path>.*)$ The current path, fergana_api/files/36/movies/movie.mp4, didn’t match any of these.

Django test counting queries is failing because of SQL EXPLAIN queries
I have a test like this: from django.test import TestCase class MyTestClass(TestCase): def test_query_count(self): with self.assertNumQueries(12): some_service_call() When running tests using pytest I get an error saying that there were 24 queries instead of 12 and when checking the logged error I see that I have one EXPLAIN query per real query made by some_service_call(). This is not happening with plain django test runner (i.e: python manage.py test). Does anyone know why I'm getting these explain queries and how can I avoid getting them when testing? I'm using the official postgresql docker image. Weird thing is that when I run using pytest for that file (i.e: pytest path/to/test.py) I don't have this issue. -
How can I ensure that transaction.atomic() uses the default database for both read and write queries in Django?
This is my router，to ensure read-write separation. class Router(object): """ A router to control all database operations on models in the auth application. """ def db_for_read(self, model, **hints): """ Attempts to read auth models go to auth_db. """ return 'readonly' def db_for_write(self, model, **hints): """ Attempts to write auth models go to auth_db. """ return 'default' but when using transaction.atomic(), I need to use the default db for all read and write queries. One way to do this is to use using to specify the default library for all read queries, but this is cumbersome and I need to check the query in each transaction. Is there any other better plan? with transaction.atomic(): # create some objs MyModel.objects.create(name='tom', **data) # do something # query count = MyModel.objects.using('default').filter(name='tom').count() -

My Django website doesn't update HTML and CSS code
I'm building Django website and when I wrote HTML code and reload the page, it didn't make anychanges and when I tried to change the background color to red, it didn't chnaged, even when I deleted all my code in HTML file, website stayed the same.

Django hosted with cPanel crashes shortly after I change an object in models
I am working on a react-native app with Django backend. I recently deployed the Django app with cPanel. When I do an action in the app that updates or makes an object in models and then I do something that requires a lot of processing (make matches between some users which uses a probability based ai and then some "GET" methods for images stored on the app) it causes the domain to crash for about 30 seconds and then it works again. This problem does not happen when I try running the Django app through my computer (not deployed). This part is very important for the rest of my project. Is there something I can do to fix this problem? Should I consider deploying it on something other than cPanel? -
How to display a 3D object (*.stl file) using Django
I have a website developed using Django. Several 3D object files (*.stl files) are loaded from the administration. I would like to add the following two functionalities. 1- Being able to view 3D objects, both for an administrator and for a regular user. 2- In case of being a regular user, the object is only downloadable, under some conditions (for example if the user pay for the article.) The following site is a good benchmark of what I want. sketchfab I don't even know how to proceed, any comment would be welcome. -
What are the steps to integrate a Javascript framework (like React or Svelte) into a Django app for stat tracking purposes?
I've been working on a web app using Django that will track stats for an intramural league I'm involved in. I have just about all the models I need and I'm slowly putting together the views I need as I learn Django and develop this app. I want to create a page in my web app that will serve as a stat tracker for my league. Essentially, you could have one or two people on the sidelines watching a game, while recording stats for said game on this webpage as the game goes on. I'd like to use a Javascript front-end framework for just this page. I'd also like to be able to just plug it in to the Django app I already have without remaking the whole thing. I know of a few JS frameworks (React, Vue, Svelte), but I've only done as much as go through the interactive React tutorial. Long story short, I know next to nothing about JS frameworks. I do know a little bit about Javascript though. How would I plug in a Javascript framework to create this webpage for taking stats? What JS frameworks would you recommend I use? I like the look of … -

Retrieving data from an Excel file in Django using Pandas: How can I include duplicates that are being overwritten by Python?

How To Get Nginx Client Ip Using Revese Proxy (Django, Nginx)
I'm facing an issue with retrieving the client IP addresses from the X-Forwarded-For header when using Nginx as a reverse proxy server in front of my Django application. Currently, I'm only able to obtain the IP address of the Nginx proxy server instead of the actual client's IP. I have configured Nginx to set the necessary headers using the following directives: server { server_name example.domain.com; set_real_ip_from 0.0.0.0/0; real_ip_header X-Forwarded-For; real_ip_recursive on; location /static/ { root /home/user/example.domain.com/djangoapp; } location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://10.0.0.122:8000; } } I have tried it all, even using the map from this artlcle and alot more: link but the X-Forwarded-For and X-Real-IP are still the proxy server's IP and not the client IP! can't even get it to return a list and not just the last IP... In my Django view, I'm trying to access the client IP using request.META.get('HTTP_X_REAL_IP') and request.META.get('REMOTE_ADDR'). The headers are showing, but not the client's IP. { 'Content-Length': '', 'Content-Type': 'text/plain', 'X-Real-Ip': '10.0.0.101', 'X-Forwarded-Proto': 'https', 'X-Forwarded-For': '10.0.0.101', 'User-Agent': 'Mozilla/5.0 ...', even the user agenst is correct. but the IPs are not.

What is going on with my Django site, it's health check, and admin page? [closed]
I'm following a Django tutorial located here: https://dev.to/daiquiri_team/deploying-django-application-on-aws-with-terraform-minimal-working-setup-587g I successfully made it to step 4 located here: https://dev.to/daiquiri_team/deploying-django-application-on-aws-with-terraform-namecheap-domain-ssl-19a5 During Step 4, the author writes the following: I was able to receive Healthy! from the 127.0.0.1:8000/health url. Also, at one point I was able to get Bad Request from my equivalent Load Balancer domain, however I destoryed and rebuilt the underlying infrastructure, and now I get Not Found from both the AWS Load Balancer domain and the /health/ check, however the /admin/ page successfully loads and allows me to login (although I did not attempt to login). Could someone help explain what is going on? I'd like the AWS Load Balancer page to load Bad Request, same with the /admin page I presume...but the Health check should show Healthy. Lastly, my custom domain isn't working any longer either. I'm assuming that is because of my infrastructure tear down and rebuild...it updates the name servers for DNS and I think they take a days to correct. -
TypeError in Django: "float () argument must be a string or a number, not 'tuple.'"
Description: When attempting to access a specific page that relate to a cryptocurrency, in this case Dogecoin, I receive a TypeError in my Django application. "Field 'bought_price' expected a number but got (0.07314770668745041,)" reads the error notice. The traceback also states that the problem is with the float() function and that a tuple was used as the argument. The passed value, however, is not a 'tuple'. It is a numpyfloat64 type, therefore I tried passing the same value after converting it to a float type in Python. Even if I provide the form a static value, the problem still occurs. form.instance.bought_at = 45.66 results in the same issue. Could anyone help me understand why this error is occurring and how I can resolve it? Here's the relevant code: Model Code: class Order(models.Model): coin = models.CharField(max_length=100) symbol = models.CharField(max_length=50) bought_price = models.FloatField() quantity = models.IntegerField(default=1) bought_at = models.DateTimeField(default=datetime.now) user = models.ForeignKey(User, on_delete=models.CASCADE) View Code: ticker = yf.Ticker(symbols[pk]) price_arr = ticker.history(period='1d')['Close'] price = np.array(price_arr)[0] if request.method == 'POST': form = BuyForm(request.POST) if form.is_valid(): form.instance.coin = ticker.info['name'], form.instance.symbol = ticker.info['symbol'], form.instance.bought_price = price, form.instance.user = request.user form.save() return redirect('portfolio') else: form = BuyForm() I appreciate any assistance or insights you can provide.

How can I allocate chat memory to the openai model

How can I properly interact with many-to-many relationship in Django+GraphQL when working with Project and User models?
How do I properly interact with many-to-many relationship in Django+GraphQL? I have a Project model which has a many to many relationship to User model. class Project(models.Model): title = models.CharField(max_length=256, blank=True) users = models.ManyToManyField(to=User, blank=True, related_name='projects') class User(AbstractUser): email = models.EmailField(max_length=128, verbose_name='email address', blank=False) EMAIL_FIELD = 'email' USERNAME_FIELD = 'username' I need to connect it to GraphQL so I can read and modify that fields via mutations. I already have a schema to work with Project without users but now I need to add users as well { projects { edges { node { id title } } } } But it doesn't work when I add users because the Project table in db doesn't have a users field. It has the projects_project_users table that describes their relationship. How can I modify my code to be able to work with project.users field? -

django makemigrations --check with output?
I'm trying to combine two behaviours of the makemigrations command in my CI: makemigrations --check will return non-zero when a migration file needs to be generated makemigrations --dry-run will print details about the ungenerated migration makemigrations --check --dry-run behaves as makemigrations --check (since Django 4.2). My CI script needs to fail if there are ungenerated migrations and it would be helpful if it also described the missing migrations. Is there a cleaner way to do this besides some bash tricks involving both options? -
Why is my Django CreateView not adding new recipes to the database?
My Django CreateView doesn't submit data to the database. I am an absolute beginner when it comes to Django and creating websites and I feel like there's something that i haven't quite understood yet. I tried following tutorials and ended up with a draft of a recipe sharing website for a uni project, but, even thought the other CRUD views can access the database, it looks like the one that's supposed to create a new recipe can not. It does not display any errors, nor show something not working, when I press "Confirm" it justs refreshes the page and doesn't add anything to my database (I'm using Django's default db). This is my code, sorry for the poor quality but I'm doing my best to learn: Models: class Category(models.Model): CATEGORY_CHOICES = [ ('Easy', 'Easy'), ('Medium', 'Medium'), ('Hard', 'Hard'), ] name = models.CharField(max_length=100, choices=CATEGORY_CHOICES) def __str__(self): return self.name class Meta: app_label = 'recipes' class Ingredient(models.Model): name = models.CharField(max_length=125) amount = models.CharField(max_length=250, blank=True, null=True) def __str__(self): return self.name class Meta: app_label = 'recipes' class Recipe(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey(User, on_delete=models.CASCADE) category = models.ForeignKey(Category, on_delete=models.CASCADE) description = models.TextField() ingredients = models.ManyToManyField(Ingredient, related_name='recipes') instructions = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) … -
