Adding product with size to shopping bag django
I am developing my hobby ecommerce store website. The products in the store can have different sizes. Wehen we go to product details page I am able to render the product's available sizes. I have also built shopping bag page and can add products to the shopping cart. Product detail page shows product color, product size and quantity. I am rendering the size in a button at the moment. When I click on Add to Bag button I want a function that checks if any size is selected, if not then raise an error message for user but if any size is selected by user then this should be sent to the view so it can be handled accordingly. Here are my models, product detail template and product detail view: if anyone please guide me.... class Product(models.Model): """ Product model to allow creating product records and linking with category """ product_uuid = models.UUIDField( default=uuid.uuid4, editable=False, unique=True) product_name = models.CharField(max_length=255) sub_category = models.ForeignKey( 'SubCategory', on_delete=models.CASCADE, related_name='products') product_description = models.TextField() has_sizes = models.BooleanField(default=False, null=True, blank=True) is_featured = models.BooleanField(default=False) product_sku = models.CharField(max_length=255, null=True, blank=True) product_price = models.DecimalField(max_digits=6, decimal_places=2) def __str__(self): return self.product_name class Meta: verbose_name = 'Product' verbose_name_plural = 'Products' ``` ``` class … -
How to write an async for database function?
I have a function that is written as so: @database_sync_to_async def list_values(self): return list( Model.objects.all().select_related("related").order('date')[::-1] ) I'm trying to rewrite to work with an async for loop async for value in self.list_values. However my current attempt async def list_values(self): return ( Model.objects.all().select_related("related").order('date')[::-1] ) Gives me an error 'async for' requires an object with __aiter__ method, got coroutine. I've also played around with adding await and yield, etc. but to no end. Any suggestions and an explanation of how I'm thinking about this wrong? -
eBay HTML CSS description template image gallery loop
Hi I'm currently playing around with updating our stores eBay HTML description template, we use the inkfrog software for listing so I've got to play around with the HTML setup. I'm trying to get the images for each product to be displayed like this in the description: The original HTML for this gallery looks like this: <div class="col-sm-12 col-md-6 col-lg-6 mb-5"> <div class="gallery"> <input type="radio" id="image1" class="image-selector" name="image-selector" checked="checked"> <img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-1.jpg" class="img-fluid main-image animated fadeIn"> <input type="radio" id="image2" class="image-selector" name="image-selector"> <img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-2.jpg" class="img-fluid main-image animated fadeIn"> <input type="radio" id="image3" class="image-selector" name="image-selector"> <img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-3.jpg" class="img-fluid main-image animated fadeIn"> </div> <div class="thumbs"> <ul class="text-center"> <li><label for="image1"><img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-1.jpg" class="thumb"></label></li> <li><label for="image2"><img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-2.jpg" class="thumb"></label></li> <li><label for="image3"><img src="https://poseidongames.co.uk/wp-content/uploads/2017/11/sub-nautica-below-zero-3.jpg" class="thumb"></label></li> </ul> </div> </div> I've managed to get the thumbnail images to cycle through the images array and display: using this code: `<div class="thumbs"> <ul class="text-center"> {% for image in images%} <li><a href="{{ image.url }}"><img src="{{ image | image_size:'600px' }}" class="thumb"></a></li> {% endfor %} </ul> </div>` ``` What I'm struggling with is the large section...

AWS App runner build fail: pkg-config not found when building wheel for pycairo in django project
I am trying to deploy a django project to AWS App runner and it uses xhtml2pdf which needs pycairo in its dependency. It works locally I believe because I am running ubuntu, which is labeled this as "pkg-config" but since AWS App runner is running a different distro where it recognizes "pkgconfig". I tried to change the export path but that did not seem to work. The error is listed below Image of output from AWS app runner I also tried to run the following commonds yum install pkgconfig but it was already installed. I also tried yum install cairo but it also already installed. It seems like the packages are there before running requirements.txt but it cant find it. -

Django: count values with annotation from another table without ForeignKey
I have three models/tables: class Stats: obj_type = models.TextField(blank=True, db_index=True) obj_id = models.PositiveIntegerField(blank=True, null=True, db_index=True) views_count = models.IntegerField(blank=True, null=True, default=0) class Movie: title = models.TextField(blank=True) producer = models.TextField(blank=True) class Cartoon: title = models.TextField(blank=True) producer = models.TextField(blank=True) In total, I have around 1,500,000 objects in my Stats table. The obj_type field in it holds strings such as 'Movie' or 'Cartoon' related to the respective tables. What I want to do is to get a list of all the Movie producers from the Movie table with the total count of views pertaining to every producer, e.g.: Walt Disney: 17055 # total views of all Movies with 'Walt Disney' as producer counted based on Statistics table Netflix: 15046 etc. What is the most effective way to achieve this without having a ForeignKey? I.e. something like this if we had the views count inside the same table: views = Movie.objects.values('producer').annotate(count=Sum('views_count')) -
How to force exit Django app when database connection fails
I am trying to have django asgi app exit when the database connection fails. Normal behaviour seems to be that the app and its endpoint happily keep running and are accessible even though the database connection has failed. I want the app to exit.

How to create a separate user base in Django without extending the user model
So I am trying to build a website in Django where I want two separate user bases like users and agents. An agent can be an agent without being a user. Agents have a separate login url and users have a separate login url. This is where I am stuck. I can't seem to create a different login page for agents. Anyone can apply to be an agent without logging in/registering as a user, then if he/she meets requirements, he/she will be registered as an agent in the admin panel by a superuser. My models.py: from django.contrib.auth.models import User class Agent(models.Model): name = models.CharField(max_length=100) password = models.CharField(max_length=100) image = models.ImageField(upload_to = 'Images/') bio = models.TextField() instagram = models.URLField(max_length=100) twitter = models.URLField(max_length=100) facebook = models.URLField(max_length=100) linkedin = models.URLField(max_length=100) is_featured = models.BooleanField(default = False) slug = models.SlugField(default='') def __str__(self): return f'{self.name} Agent Profile' My forms.py: class AgentSignInForm(AuthenticationForm): username = forms.CharField(max_length=100) password = forms.CharField(max_length=100) def clean(self): cleaned_data = super().clean() username = cleaned_data.get('username') password = cleaned_data.get('password') return cleaned_data My models.py: class AgentLoginView(LoginView): form_class = AgentSignInForm def form_valid(self, form): form.send_email() return super().form_valid(form) -

Django field validation warnings
I am new to Django and confronted with the following problem: Usually I have a form where I have defined my fields and according validation rules. Usually there are fields which have potentially invalid inputs. These are then validated and an error is shown in case. An invalid form leads to the expected behaviour that the data isn't persisted to the database. Now I have a form where I have strict validation rules which should lead (to displaying) an error and data not persisting to the database and besides I have looser validation rules which should lead to displaying of a warning/hint but persisting to the database. Example I have a list where the user could enter how many male, female and diverse participants were in a given course. Later on I ask questions about how many male, female and diverse partcipants would like to do another course from our program. There may be inconsistencies at the moment which I want to warn about but nevertheless accept / save the data as given. Is there any mechanics in Django which allows displaying "warnings", "hints" etc. per field like the error messages? -
Creating django models and setting its default to existing 'Users'
My application already has some existing users. Now, I want to add a 'Follower' feature, so I created a Follower model: class User(AbstractUser): pass class Follower(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='follower', null=True) following = models.ManyToManyField(User, related_name='following', blank=True) Is there a way I can set the existing Users as its default for the user(follower) column in Follower model?. Upon clicking the follow button, in the backend, I coded it so that if the user (follower) in the Follower model does not exist, it will create the user (follower) and then add the followed user to its 'following'. Otherwise, it will immediately add the followed user to its 'following' in the Follower model. IT WORKS. BUT. I want to know if there is still any other way to do it in the models.py. -

Problem with Django class-based LogoutView in Django 5.0
I used Django class-based login and logout views by "django.contrib.auth.urls", login feature works correctly, but when logging out via the link "http://127.0.0.1:8000/accounts/logout" it returns an http 405 error page, saying "method not allowed (GET)". I found out this logout feature was available in django 4.0 but in django 5.0 it's removed. Support for logging out via GET requests in the django.contrib.auth.views.LogoutView and django.contrib.auth.views.logout_then_login() is removed. -djangoproject.com How can I fix it? I think I should somehow make it use POST request instead GET request when loging out but don't know how.
