How can I query all products with their variation attributes?
I have following database schema: Django models: class Product(models.Model): name = models.CharField(max_length=150) # price and so on class Size(models.Model): value = models.CharField(max_length=20) class Color(models.Model): value = models.CharField(max_length=20) class Variation(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name="variations") size = models.ForeignKey(Size, on_delete=models.CASCADE) color = models.ForeignKey(Color, on_delete=models.CASCADE, null=True, blank=True) So I can write: product.variations But I also want to be able to write product.sizes product.colors to get all sizes or colors that this product has in variation table The problem that I'm trying to solve: I have product card list. And each card has options of sizes and colors to choose and to add to their cart. I want to show the user sizes and colors that this particular product has in database to not list all the sizes and colors from database. But variations can have duplicates, for example, consider these combinations: size - 40, color - red size - 42, color - green size - 44, color - red (again) size - 42 (again), - color gray I want to show the user sizes: 40, 42, 44 colors: red, green, gray Now I can show all of them with duplicates like sizes: 40, 42, 44, 42 colors: red, green, red, gray It is … -

How do I get the value of a field of a model instance using the instance's pk?
The following line of code correctly prints the id number of the specific model instance that I'm interested in: views.py print(self.kwargs['pk']) Great. But how do I get the value of a field in that model instance? The following is not working, because I think it's returning the default value listed in the model class and not the value in the model instance: instance_fieldname = self.kwargs.get(ModelName.fieldname) Hoping this is a simple fix. Thank you. -

UndefinedTable: relation "user" does not exist
I am deploying a fresh new Django app on the server. The problem is when I migrate all the apps in the project. I'm getting UndefinedTable: relation "user" does not exist. Things I have done already: removed all the migrations from all the apps created a new database and new migrations and still getting that error. Weird scenarios: After deployment when I run the Django app locally on the server and hit API locally on the server using curl everything is working fine. like user sign up, but when I try to see in the database it is just empty (refer to the screenshot below). it doesn't even show columns for this user table, but for other tables, I can see columns as well. after migrations I am able to create super user but when I tried to login getting 500 error. and Undefined table relation user does not exit.

Resolving A Django Error on Form: Object has no attribute
Hi I'm trying to create a form that will when used update one model (Command_Node), and at the same time create an instance of another model (EC_NODE) that has a many to one relationship with the Command_Nodes. However when I go onto the update view and submit the form I'm getting the following error any ideas on how I can resolve this error? Thanks for any help you can offer. AttributeError at /website/update/1 'Beacon' object has no attribute 'EC_Node_set' Request Method: POST Request URL: http://127.0.0.1:8000/website/update/1 Django Version: 4.0.4 Exception Type: AttributeError Exception Value: 'Beacon' object has no attribute 'EC_Node_set' This on traceback points to command_form.EC_Node_set.all() # <- not sure with all _ and Maj here Which I can understand. I think my intention here should be clear enough. I want to set an instance of EC_Node to hold the command just put in via the form, and I understand the error. I just don't know how to get around it so that the view/form does what I want. Relevant views.py def update(request, host_id): host_id = Command_Node.objects.get(pk=host_id) form = Command_Form(request.POST or None, instance=host_id) if form.is_valid(): # Original suggestion was command_form = Command_Form.objects.first() command_form = form.cleaned_data['host_id'] command_form.EC_Node_set.all() # <- not sure with … -

Media Streaming Servers for Django
I and my team are starting a project where in we are building a scalable live streaming platform just like Youtube. We are using Django as the backend framework. Which is the best media streaming library/server that can be used to achieve the result(It should work along the django project)? Previous Attempts : We researched about various media streaming servers and shortlisted the following three(based on our requirements that it should be able to scale up to a commercial level): Ngnix RTMP module https://github.com/arut/nginx-rtmp-module/ Node Media Server https://github.com/illuspas/Node-Media-Server Django Channels https://channels.readthedocs.io/en/stable/ We are struggling to decide which one to use for our project. I have seen a lot of people use Django channels with django to deal with such projects. But one of my teammates had a bad experience with django channels while working on a similar project hence he is advising us not to go with it. Ngnix module is attractive and a really good reputation on github but I didn't understand it well. We are very doubtful of Node Media server, no positive reviews nor negative reviews. Can you please suggest a better option maybe among them or a different one? Thank you! Any suggestions are welcome. -

How to update the user profile of a different user if you are logged in as the owner?
Currently, I am logged in as an owner and I want to update the fields of customers in the database. But the form does not update or show the details as a placeholder because the user model has extended the customer model and hence, the customer model does not have its own fields. How do I get the instance of the User of the Customer in the UpdateView?/How do I update the customer? views.py class CustomerUpdateView(OwnerAndLoginRequiredMixin, generic.UpdateView): template_name = "customer_update.html" form_class = CustomerModelForm queryset = Customer.objects.all() def get_success_url(self): return "/customers" models.py class Customer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return self.user.username class User(AbstractUser): is_owner = models.BooleanField(default=True) is_agent = models.BooleanField(default=False) is_customer = models.BooleanField(default=False) forms.py class CustomerModelForm(forms.ModelForm): class Meta: model = User fields = ( 'email', 'username', 'first_name', 'last_name', ) -
Django: Accessing full User information via ManyToMany field
everyone- I'm new to Django and working on my first big project and I'm having trouble with accessing default Django User model information via a ManyToMany relationship. I've spent a great deal of time searching and can't crack it. models.py class Event(models.Model): event_name = models.CharField(max_length=200, null=True, unique=True) #etc... class School(models.Model): user = models.ManyToManyField(User) event = models.ForeignKey(Event, null=True, on_delete=models.PROTECT) #etc... My url contains the id of the Event, so... views.py def schools(request, pk): event = Event.objects.get(id=pk) school = School.objects.filter(event=event) return render(request, 'accounts/schools.html', {'event':event, 'school':school}) template {% for school in school %} <tr> <td>{{school.name}}</td> <td>{{school.user.all}}</td> {% endfor %} On my template, I'm able to use {{school.user.all}} to get me a Queryset displayed with the username of each User, but I want the first_name and last_name and can't see to figure out how to get that.. Thank you for any suggestions. I greatly appreciate your time! -

Call ajax of `django-restframework` api from template and the server checks who calls this api
I use google auth login in django project with django-oauth-toolkit What I want to do is Call ajax of django-restframework api from template and the server checks who calls this api. For example, I can get if user is login or not {% if user.is_authenticated %} in template. so, I can call the api with the user information like this. var url = "http://localhost/api/check?id={{user.email}}" $.ajax({ method:"get", url:url .... with id query server can understand who calls this request. However in this method,id is written barely, so you can make the fake request. So, I guess I should make some access token or some other key. Is there any general practice for this purpose??? -

Display all User profiles, in Django template, liked by the currently logged-in User (under ManytoMany field)
I built a portal, where members can see other users' profiles and can like them. I want to show a page where the currently logged-in users can see a list of profiles only of the members they liked. The Model has a filed 'liked', where those likes of each member profile are stored: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') company = models.CharField(max_length=500, blank = True) city = models.CharField(max_length=100, blank = True) website = models.URLField(max_length=500, blank = True) liked = models.ManyToManyField(User, related_name='user_liked', blank=True) My views.py, and here I only show all members so on my template I can loop through each member in members... Including 'member.profile' details from the Profile model. @login_required def all_fav_members(request): users = User.objects.all context = {'members':users} return render(request, 'club/all_fav_members.html', context) I've tried many things, both under views.py and my HTML template, but I was not able to loop through all users associated with a specific Profile under the 'liked' field where that user is equal to request.user.
