Want to retrieve a Foreign Key value instead of the whole object with django-rest-framework serializers
I'm using the Django rest framework to create an API. I have the following models: (https://i.stack.imgur.com/oasDY.png)](https://i.stack.imgur.com/oasDY.png) models.py class Faculty(models.Model): name = models.CharField(max_length=25, unique=False, null=False, blank=False) email = models.EmailField(max_length=25, unique=True, null=False, blank=False) class Course(models.Model): name = models.CharField(max_length=25, unique=True, null=False, blank=False) faculty_name = models.ForeignKey(Faculty, on_delete=models.CASCADE, related_name='faculty_name') end_date = models.DateField() def __str__(self): return self.faculty_name # @property # def faculty_name(self): # return self.faculty.name To create a serializer serializers.py class FacultySerializer(serializers.ModelSerializer): class Meta: model = Faculty fields = '__all__' class CourseSerializer(serializers.ModelSerializer): # faculty_name = serializers.SlugRelatedField(slug_field='name', read_only=True) # faculty_name = serializers.ReadOnlyField(source='faculty.name') print(Faculty.objects.all().values('name')) class Meta: model = Course fields = ('name', 'faculty_name', 'end_date') To create rest services using the following views: views.py class Course(mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView): serializer_class = CourseSerializer queryset = Course.objects.all() def get(self, request, *args, **kwargs): return self.list(request, *args, **kwargs) def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) class Faculty(mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView): serializer_class = FacultySerializer queryset = Faculty.objects.all() def get(self, request, *args, **kwargs): return self.list(request, *args, **kwargs) def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) Getting the Faculty object while accessing the /course/ endpoint as shown in the image. want to get the faculty name instead of the Faculty object in the post method's form fields(dropdown) I have tried the below codes: 1)faculty_name = … -
multipart/form-data not setting in MultipartEncoder (python)
I am trying to upload a file to a server and it only accepts the file in multipart/form-data format so when i try to send it by encoding like: m = MultipartEncoder( fields={'document': json.dumps(metadata), 'files': (file_name, open(file_path,'rb'),'multipart/form-data')} ) headers = {'content-type': m.content_type} response = requests.post(url, headers=headers, data=m) It still shows the error: '{"success":false,"errorMsg":"Content type 'application/octet-stream' not supported"}' How do i resolve this when i have explicitly set the content-type to multipart/form-data? -
request.FILES in Django
I need the following code to work as written: testo = request.POST.get('testo') lang = request.POST.get('lang') audio = request.FILES['audio'] fs = FileSystemStorage() filename = fs.save(audio.name, audio) uploaded_file_url = fs.url(filename) The problem is that for request.FILES the form is required to be - enctype="multipart/form-data" - My form instead is like this: <form action="{% url 'app' %}" method="post"> {% csrf_token %} <textarea name="testo" id="" cols="30" rows="10"></textarea> <label for="lang">Scegli lingua:</label> <select name="lang" id=""> <option value="it">Italiano</option> <option value="en">Inglese</option> <option value="es">Spagnolo</option> </select> <input type="file" name="audio" id=""> <button type="submit">INVIA</button> </form> With my form I can get the text to work, but I can't get request.FILES to work!!! Any solution? Unfortunately I can't with my form. I need it as is, but I need something that allows me to make text and files work in Django -
Why does Django add 1 second to the lifetime of a cookie?
I'm trying to implement JWT authentication using django-graphql-jwt on the backend, and nuxt3 for the frontend. My token and refresh_token are stored in cookies, and I wrapped the GraphQLView in a jwt_cookie decorator that automatically checks for the existence of the jwt token in the cookie, as well as its validity. In general, everything works great. When I send an authorization request, the backend returns me the "Set-Cookie" headers for JWT and JWT_REFRESH_TOKEN with an expiration date that automatically deletes them as soon as they become invalid, which saves me a lot of code/logic on the frontend. However, there is one very unpleasant thing - Django adds 1 second to the cookie lifetime for some reason in the set_cookie function, and it ruins everything. Here is the Django code: def set_cookie( self, key, value="", max_age=None, expires=None, path="/", domain=None, secure=False, httponly=False, samesite=None, ): self.cookies[key] = value if expires is not None: if isinstance(expires, datetime.datetime): if timezone.is_naive(expires): expires = timezone.make_aware(expires, datetime.timezone.utc) delta = expires - datetime.datetime.now(tz=datetime.timezone.utc) # Add one second so the date matches exactly (a fraction of # time gets lost between converting to a timedelta and # then the date string). # Here's what I mean ↓↓↓ delta += datetime.timedelta(seconds=1) … -
Django using Subquery in annotate: How to fetch all rows that match the condition of filtering
I have two models with M2M field. Because there wont be any update or deletion (just need to read data from db) I'm looking to have single db hit to retrieve all the required data. I used prefetch_related with Prefetch to be able to filter data and also have filtered objects in a cached list using to_attr. I tried to achieve the same result using annotate along with Subquery. but here I can't understand why the annotated filed contains only one value instead of a list of values. let's review the code I have: some Routes may have more than one special point (Point instances with is_special=True). models.py class Route(models.Model): indicator = models.CharField() class Point(models.Model): indicator = models.CharField() route = models.ManyToManyField(to=Route, related_name="points") is_special=models.BooleanField(default=False) views.py routes = Route.objects.filter(...).prefetch_related( Prefetch( "points", queryset=Point.objects.filter(is_special=True), to_attr="special_points", ) ) this will work as expected but it will result in a separate database querying to fetch the points data. in the following code I tried to use Subquery instead to have a single database hit. routes = Route.objects.filter(...).annotate( special_points=Subquery( Point.objects.filter(route=OuterRef("pk"), is_special=True).values("indicator") ) the problem is in the second approach will have either one or none special-point indicator when printing route_instance.special_points even if when using prefetch the printed … -
Why does the ImageGalleryBlock in wagtail-crx/coderedcms return no images?
Wagtail-CRX installs with a pre-defined StreamField ImageGalleryBlock that allow a user to select a Collection of images that are then output to the page along with a modal pop-up structure. In models.py of my app I have created the image_gallery variable like this image_gallery = StreamField([ ('image_gallery', ImageGalleryBlock()), ], verbose_name="Choose images for the gallery", null=True, blank=True, default="", use_json_field=True ) FieldPanel("image_gallery"), This worls fine. The FieldPanel adds the Collection choice block to the page edit form. However, the images in the chosen Collection never appear on the page using any of the possible methods for calling the block into the page template e.g. {% for block in page.image_gallery %} <section>{% include_block block %}</section> {% endfor %} The include here calls in the block using the template image_gallery_block.html - the structure for the modal pop-up is rendered on the page but there no images appear to populate it with. Inside the image_gallery_block.html template the first line is {% get_pictures self.collection.id as pictures %} where get_pictures is a function that should pass the data from the Collection objects into the variable pictures and they should be iterated over in the subsequent template html thus {% if pictures %} {% for picture in pictures … -
Getting 404 error when trying to use slugs in Django
I'm new one in Django and trying to develop website. What I need is to use slugs in URLs in Django. When I use id's everything works well. I have done the following steps: I have a model Posts with . class Post(models.Model): title = models.CharField(max_length=100) slug = models.SlugField(max_length=100, unique=True, default='') content = models.TextField() category = models.ForeignKey(Category, on_delete=models.CASCADE, null=True, blank=True) photo = models.ImageField(upload_to='post_photos/', blank=True) # ImageField для хранения изображений created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) is_published = models.BooleanField(default=False) def __str__(self): return self.title def save(self, *args, **kwargs): if not self.photo: # Если поле photo пустое, генерируем случайный путь к изображению random_image_path = get_random_image_path() self.photo = random_image_path # Привязываем случайное изображение к объекту Post super().save(*args, **kwargs) def get_absolute_url(self): return reverse('post', kwargs={'post_slug': self.slug}) I have written the following in my urls.py and views.py path('fitness/<slug:post_slug>/', views.show_post, name='post'), def show_post(request, post_slug): post = get_object_or_404(Post, slug=post_slug) return render(request, 'show_post.html', {'post': post}) and this works well.

How to configure django 5.0.3 to be able to use private/public media files on AWS - s3

Request header field access-control-allow-origin is not allowed by Access-Control-Allow-Headers in preflight response, nginx, django, waitress
I'm using nginx server to serve static React js files and waitress server for django rest framework with 0.0.0.0:8000 as address to serve api's. I'm using nginx as a reverse proxy for django. Even though i have modified django setting to allow all origins and modified nginx conf file to include cross origin headers and pre-flight headers. I'm still getting an error saying "Access to XMLHttpRequest at 'http://15.295.156.60:8000/core/profile/profile/' from origin 'http://15.295.156.60' has been blocked by CORS policy: Request header field access-control-allow-origin is not allowed by Access-Control-Allow-Headers in preflight response."

Edit Form in Modal Window Django
I am trying to do an Edit form in the modal window. The problem is that I cannot pass the form into the modal window and show the modal.

Reading IPTC information Django
I have published my django project on shared hosting, there are no problems at all. Everything seems to work as it should, but as soon as the system is to read IPTC information from images, it does not work. I get absolutely no errors, but it doesn't read the information. But in the local development server on my macbook it works without problems, then it reads the iptc information. Both use the same code, the same python version and the same Pillow. What should I do? I have tried to change the code a bit, but to no avail. -

Django queryset remains empty initially but populates after creating an object without re-running the query. How is this possible?
I'm encountering a perplexing issue in my Django application. I have a queryset (qs) obtained from a database query at the beginning of a DRF api call. Strangely, this queryset appears empty upon inspection. However, as I continue through the code execution, I create an object for the same model without re-running the queryset, and to my surprise, the queryset suddenly populates with the newly created object. Here's a simplified version of what I'm experiencing: # Initial queryset initial_qs = MyModel.objects.filter(some_condition=True) # At this point, initial_qs appears empty when I print it or inspect its contents # Creating an object without re-running the queryset new_object = MyModel.objects.create(some_field='value') # Now, if I print initial_qs or inspect its contents again, it contains the newly created object # How is it possible that the queryset remains empty initially but populates later without re-running the query? Is there something I'm overlooking in Django's ORM caching mechanism or the way queryset evaluation works? -
Need help in optimizing the seriliazer

Cassandra: "Model keyspace not set" and "Connection name doesn't exist in the registry" Errors
I recently upgraded to Django 4.2 and am facing issues with Cassandra integration. Initially, I encountered the following error when attempting to generate queries: cassandra.cqlengine.CQLEngineException: Model keyspace is not set and no default is available. Set model keyspace or setup connection before attempting to generate a query. This error was thrown despite specifying the model keyspace in settings.py. As an attempted fix, I explicitly set the keyspace in my models like so: __keyspace__ = "my_keyspace" However, this led to a new set of errors related to connection names not existing in the registry: Connection name '<object object at 0x7f4fb00d67a0>' doesn't exist in the registry. This issue persists across multiple models and queries.

Django Deployment on AWS EC2 with Docker Compose: Seeking Advice on Security, Scalability, and Best Practices
I am currently working on deploying a Django application to an AWS EC2 instance using Docker Compose. The setup involves containerizing both the Django app and NGINX, with AWS RDS utilized for the database. Additionally, there's a Redis service planned for use with a Celery worker. While the deployment process is functional, I have several questions and areas I'd like to improve. Current Setup: Dockerfiles are used to create images for the Django app and NGINX, each requiring a 'TAG' variable. Docker Compose is configured to utilize environment variables and create three services: Django app, NGINX, and Redis (for future Celery worker). GitHub Actions workflow is implemented with two jobs: 'build' to build and push Docker images (tag: short version of the SHA-1 hash of the latest commit), and 'deploy' to copy Docker Compose to EC2 and execute the deployment. Questions and Areas for Improvement: HTTPS Implementation: Currently, the setup only supports HTTP. Resource Limitation: Is it advisable to limit resources in Docker Compose? Locally, I noticed high CPU usage initially. How can I control this on EC2 to prevent performance issues? Multiple Environments: I aim to establish separate staging and production environments. Should I utilize AWS RDS for staging, … -
