Not able to display image uploaded using django
I was able to upload image using views and templates in django but was not able to display those images. I could only display images stored in static folder but not from the media folder or any other location. I have done all the steps mentioned in docs and in other solution but this is not working for me. I created a model which looks like class Product(models.Model): image = models.ImageField(upload_to='product_images/') description = models.TextField(null=True) quantity = models.IntegerField(null=True) and my forms.py is class ProductForm(forms.ModelForm): class Meta: model = Product fields = ['image', 'description', 'quantity'] my views.py is like this @login_required def display_products(request): products = Product.objects.all() return render(request, 'farmer/display_products.html', {'products': products}) @login_required def upload(request): if request.method == "GET": form = ProductForm() if request.method == 'POST': form = ProductForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('display_products') return render(request, 'farmer/my_products.html', {'form': form}) my file is like this {% load static %} {% for product in products %} <div class=""> <h2>{{ product.name }}</h2> {{product.image.url}} image: <img src="static/dry.jpeg" alt="sample"> <p>description: {{ product.description }} quantity: {{ product.quantity }} </p> </div> settings.py STATIC_URL = 'static/' STATICFILES_DIRS = [ BASE_DIR / 'static/css', ] LOGIN_URL = 'login' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') DEBUG = True urls.py if settings.DEBUG: urlpatterns … -

Django annotate method with when clouse using query key as a Value
I need to add ordering_datetime column when field=field matches. And for a Value I want to get it from "date_time_value" field. queryset = queryset.annotate( ordering_datetime=Case( When( field=field, then=Value("date_time_value") ), output_field=DateTimeField(), ) ).order_by("pk", f"{order_lookup}ordering_datetime").distinct("pk") how to get value from column that matches field=field rows. when I tried to give the column name directly as a value doesn't work. It expects a static value, not a query key -
Angular CLI Proxy + Django Backend not working with Docker
I have an Angular + Django project where I am providing an api to angular with django. When I run the two services separately everything works as expected. When I run both services together using docker compose, angular is suddenly unable to connect to the backend api service. I have seen a similar post on stack but the difference is I am using a single compose file to include two different compose files so I'm not sure how to "link" the backend services to the frontend service like the answers suggest in this post. So what can I do to make this work within docker?

Choosing between Polymorphic Associations and Separate Tables
I'm working on a Django project where I need to manage generic attachments across different entities in my system. Currently, I'm using a polymorphic model as follows: class AttachmentGenericModel(BaseModel): content_type = models.ForeignKey(ContentType, on_delete=models.SET_NULL, null=True, blank=True) object_id = models.UUIDField(null=True, blank=True) content_object = GenericForeignKey('content_type', 'object_id') file = models.FileField(upload_to=upload_to_path) class ProblemStatement(BaseModel): context = models.TextField() files = GenericRelation(AttachmentGenericModel) class Proposal(BaseModel): files = GenericRelation(AttachmentGenericModel) However, I'm wondering if it's preferable to use separate tables for each entity, like ProposalFile, ProblemStatementFile, etc. My concern is that the main table AttachmentGenericModel may become complex over time as the number of entities involved grows. I'm curious if anyone has experiences or advice on which approach is more advantageous in terms of performance, maintainability, and scalability. Additionally, what considerations should be taken into account when deciding between polymorphic associations and separate tables for handling generic attachments in Django? As an illustrative example, here's an example with separate tables: class ProblemStatementFile(BaseModel): problem_statement = models.ForeignKey(ProblemStatement, on_delete=models.CASCADE) file = models.FileField(upload_to=upload_to_path) class ProposalFile(BaseModel): proposal = models.ForeignKey(Proposal, on_delete=models.CASCADE) file = models.FileField(upload_to=upload_to_path) What are the pros and cons of each approach, particularly in a future scenario where numerous new tables with file relationships may be needed? Thank you in advance for your valuable insights! -
Making a Highest Rated Albums List Based on Ratings Averages from Two Models
I have an Album model (shortened for space): class Album(models.Model): creator = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) artist = models.CharField(max_length=255) title = models.CharField(max_length=255) rating = models.IntegerField( choices=[(i, i) for i in range(1, 11)], validators=[MaxValueValidator(10), MinValueValidator(1)], default=10, ) comment = models.TextField(null=True, blank=True) And a Review model (again, shortened for space): class Review(models.Model): reviewer = models.ForeignKey(User, on_delete=models.CASCADE, null=True) album = models.ForeignKey(Album, on_delete=models.CASCADE) rating = models.IntegerField( choices=[(i, i) for i in range(1, 11)], validators=[MaxValueValidator(10), MinValueValidator(1)], default=10, ) comment = models.TextField() The Album model is for users to create an Album and add their initial review and rating. The Review model is for users to be able to add a review to an existing album, and also a rating. I have this model method attached to the Album in order to create an average rating to display in templates: def avg_rating(self): review_ratings = 0 orig_rating = self.rating review_ratings_count = self.review_set.count() if review_ratings_count > 0: for review in self.review_set.all(): review_ratings += review.rating ratings_sum = review_ratings + orig_rating ratings_count = review_ratings_count + 1 ratings_avg = ratings_sum / ratings_count avg_return = round(ratings_avg, 1) if avg_return == 10.0: avg_return = 10 else: avg_return = avg_return return avg_return else: return self.rating Sadly, avg_rating cannot be used (to my knowledge) in … -

Not able to retrive data from database in Django
I'm new to django. I am trying to obtain data from a profile page that I've created which exists in a app called users and I am trying to use the data in a HTML file called home that exists in an app called blog within in a templates directory within a blog directory This is how my users\model.py file looks like class Profile(models.Model): user = models.OneToOneField(User, on_delete = models.CASCADE) image = models.ImageField(default='default.jpg', upload_to="profile_pics") height = models.PositiveIntegerField( null=True, blank=True) weight = models.PositiveIntegerField( null=True, blank=True) age = models.PositiveIntegerField( null=True, blank=True) def __str__(self): return f'{self.user.username} Profile' def save(self,*args,**kwargs): super().save() img = Image.open(self.image.path) if img.height > 300 or img.width >300: output_size = (300,300) img.thumbnail(output_size) img.save(self.image.path) This is how my users\views.py file looks like def profile(request): u_form = UserUpdateForm(request.POST, instance=request.user) p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile) if u_form.is_valid() and p_form.is_valid(): u_form.save() p_form.save() messages.success(request, f'Your account has been updated successfully!') return redirect('profile') else: u_form = UserUpdateForm(instance=request.user) p_form = ProfileUpdateForm(instance=request.user.profile) profile_instance = request.user.profile context = { 'u_form': u_form, 'p_form': p_form, 'height': profile_instance.height, 'weight': profile_instance.weight, 'age': profile_instance.age, } return render(request,'users/profile.html',context) Just to be sure that my Profile Page works, I checked the admin page, and it shows the data in the profile section.

Media Exposure Vulnerability
Currently, we have a configuration in Django to serve media files (these are the files uploaded by users in the system). We have a URL for this where we capture all the files in the media directory and redirect them to the serve_media view. re_path(r"^media/(?P<path>.*)$", cms.views.serve_media), This is the serve_media view: def serve_media(request, path=""): if request.user.is_authenticated: user = request.user else: return redirect("/%s?next=%s" % (settings.LOGIN_URL, "/media/" + path)) usuario = Usuario.objects.get(usuario=user) # Search for the file by its path in the media folder and check if the user # has permission to access it allowed_to_serve = False try: arquivo = Arquivo.objects.get(arquivo__contains=path) # Public image of a project on the website for projeto in Projeto.objects.exclude(id_imagem_publica=None): if projeto.arquivo_in_id_imagem_publica(arquivo.id) is True: allowed_to_serve = True break if user == arquivo.criado_por or usuario.permissao == Usuario.SUPER: allowed_to_serve = True # Entidade file if arquivo.entidade is not None and allowed_to_serve is False: if ( usuario.permissao == Usuario.ENTIDADE and user == arquivo.entidade.usuario.usuario ): allowed_to_serve = True elif ( usuario.permissao == Usuario.AGENCIA and arquivo.entidade.projeto_set.all() .filter(cidade_atuacao=usuario.cidade_atuacao) .count() > 0 ): allowed_to_serve = True # Projeto file if arquivo.projeto is not None and allowed_to_serve is False: if ( usuario.permissao == Usuario.ENTIDADE and user == arquivo.projeto.entidade.usuario.usuario ): allowed_to_serve = True elif ( usuario.permissao … -
VS Code (Python) uses wrong version of Python interpreter even after activation virtual env (Poetry)
I have two Python interpreters on my machine (3.11.6 and 3.12). My project runs with Poetry venv (3.11.6). Whenever I open a project the status bar indicates correct venv like 3.11.6("project-fd1143fd-py3.11":Poetry). When I run a project (Django) I get an import error says there is no Django package installed. I suspect there is no actual activation of venv. When I enter command python --version I always get Python 3.12.0 (tags/v3.12.0:0fb18b0, Oct 2 2023, 13:03:39) There is no any indication of activated venv near the command line (do it has to be there as I remember). The Poetry venv itself works fine as I use it in PyCharm without any issues. -
Django Auth Query
I have a django backend project for e-commerce site where I have created authentication class which is used by all the view classes for incoming requests. In one of the classes I have get_queryset, put and post functions overridden. I want the authentication class to be applied for both put and post functions but not to get_queryset. following are the code snippets, Authentication Class class JWTAuthentication(BaseAuthentication): def authenticate(self, request): print('authenticating') auth = get_authorization_header(request).split() print(auth) if auth and len(auth) == 2: token = auth[1].decode('utf-8') print('Decoded Token') print(token) id = decode_access_token(token) print(id) print(id) customer = models.Customer.objects.get(id=id) return (customer, None) raise exceptions.AuthenticationFailed('unauthenticated2') Product View class class ProductList(generics.ListCreateAPIView): ... authentication_classes = [ JWTAuthentication ] ... def get_queryset(self): ... def post(self, request): ... def put... Is there a way just to apply the authentication on put and post function but not on get_queryset function? -

Deploying django project on a 2019 windows server virtual machine (offline)
I've been working on a Django project for a while, and after completing it, I want to deploy it so my colleagues can work with it. I have a virtual machine (Windows Server 2019) that doesn't have internet connection. I copied my Django project there, but the first problem I faced was with the Python packages. Since my project has its own virtual environment, I assumed that by copying the project, everything would work. However, I had to reinstall all the packages offline using the wheel files. This has made me question the purpose of the virtual environment. I also intend to deploy it using an Apache server. When deploying a Django project with Apache, I need the mod_wsgi package. However, when I tried installing it, I encountered this error, even though I have already installed Visual Studio C++ Build Tools 14 : building 'mod_wsgi.server.mod_wsgi' extension error: Microsoft Visual C++ 14.0 or greater is required.

My code looks like this: models.py class Order(models.Model): date = models.DateField('Date', null=True, blank=True) car = models.ForeignKey(Car, on_delete=models.SET_NULL, null=True) ORDER_STATUS = ( ('p', 'Processing'), ('o', 'Ordered'), ('s', 'In service'), ('c', 'Completed'), ('t', 'Taken back by customer') ) status = models.CharField(max_length=1, choices=ORDER_STATUS, blank=True, default='p') @property def order_total_price(self): order_rows = self.order_row.all() total_price = sum(row.total_price for row in order_rows) return round(total_price) @property def order_rows(self): return ', '.join(str(el) for el in self.order_row.all()) def __str__(self): return f'{self.car}' views.py class OrderListView(generic.ListView): model = Order context_object_name = "orders" template_name = "orders.html" paginate_by = 5 urls.py from django.urls import path, include from . import views urlpatterns = [ path('index/', views.index, name="index"), path('cars/', views.cars, name='cars'), path('car/<int:pk>/', views.car_detail, name='car_detail'), path('orders/', views.OrderListView.as_view(), name='orders'), path('order/<int:order_id>/', views.order_detail, name='order_detail'), path('search/', views.search_results, name='search_results'), path('', views.index, name='index'), ] and orders.html {% extends 'base.html' %} {% block header %}Orders{% endblock %} {% … -

I'm experiencing an issue which seems to be related somehow to Gunicorn + Django and I can't find the cause of the problem. I start Gunicorn using this command: gunicorn config.wsgi --bind=0.0.0.0:5000 --timeout=300 --workers=2 --threads=4 --worker-class=gthread --name=api --log-level debug --error-logfile gunicorn_error.log --access-logfile - --capture-output and then while trying to curl for example CSS file : curl http://0.0.0.0:5000/STATIC_DIR/CSS/FILE.css?v23423424 sometimes I get the correct response and CSS file but sometimes: <h1>Not Found</h1><p>The requested resource was not found on this server.</p> interestingly, if, for example, I kill 2 of the 3 gunicorn processes, they will start again in a moment and then everything will work properly. I can't find anything in the logs which can indicate the reason. Has anyone encountered a similar problem? enable DEBUG log try different types of worker-class
