Django recursive models with through
I'm trying to set up a model such that the parts of the model can have parent or child relations to each other. It was working using the automatically generated 'relationship' table, but I needed to add an additional column for quantity. I thought I had hit gold when I found this in the documentation, but I can't seem to make it work. Here's my code: class Part(models.Model): name = models.CharField(max_length=100) parent = models.ManyToManyField( 'self', symmetrical=False, through='Relationship', through_fields = ('parent', 'child'), blank=True) class Relationship(models.Model): qty = models.IntegerField(default=1) parent = models.ForeignKey(Part, on_delete=models.CASCADE, related_name='+', null=True) child = models.ForeignKey(Part, on_delete=models.CASCADE, related_name='+', null=True) When I go to add a part, I can't add a parent to it. -
How to pass extra arguments to startapp command in bash?
I want to pass values to template_context and the docs says: Any option passed to the startapp command (among the command’s supported options) What I understand is, that any extra argument that I pass, it will be set to the context dictionary. But I'm receiving the same error (django-admin startapp: error: unrecognized arguments: --options=ok) django-admin startapp name_app --template="./templates" --options="ok" I also tried with - and without it django-admin startapp name_app --template="./templates" -a_value="ok" and django-admin startapp name_app --template="./templates" some_value="ok" How am I supposed to add the extra arguments? I know must be something easy, but I'm stuck for too much time now, and I couldn't find an example that uses it. -
Users instead id , Django(wagtail) , Vue

Celery delay task gets called twice but triggers only once
I am trying to run a celery task with multiple files. Simply put in a for loop I am calling the delay method on the task and I know that it gets called because I can see the logs before being called. However, the action inside the task itself gets executed only once. in my code I have something like this: def operation(*args, **kwargs): for arg in *args: time.sleep(2) # 2s interval celery_task.delay(kwargs) And the task actually look like this @shared_task(bind=True) def celery_task(**kwargs): do_something() # async So my question is: is there some kind of check that I can't see that prevents multiple tasks to be sent, or does it have something to do with different threads? Consider that I am not sending all the tasks at once, I am using an interval of 2 seconds before calling the task each iteration in the loop. -
How to make a django api view accessible to all users?
I'm creating a Django API view for a game by extending the rest_framework.views.APIView class. It's very likely that most users will not be authenticated. How can I enforce that? As far as I know there is no permissions.IsNotAuthenticated or similar. This is the part where I have trouble in my view, where I am trying to create a game round and game session object. I have tried working around this issue by creating a pseudo-user if the user isn't authenticated: if not isinstance(request.user, CustomUser): current_user = '1' else: current_user = request.user However, I keep getting this Value error message: Cannot assign "'1'": "Gamesession.user" must be a "CustomUser" instance. Below the code section from views.py current_score = 0 if not isinstance(request.user, CustomUser): current_user = '1' else: current_user = request.user gamesession = Gamesession.objects.create( id=controller.generate_random_id(Gamesession), user=current_user, gametype=gametype, created=datetime.now() ) gameround = Gameround.create({ 'id': controller.generate_random_id(Gameround), 'user': current_user, 'gamesession': gamesession, 'created': datetime.now(), 'score': current_score, }) gameround_serializer = GameroundSerializer(gameround) -

Django DigitalOcean Apps Deployment
I have a very small application that I am working on. I have everything up and running locally but can't get it deployed to DigitalOcean Apps. I have re-read all the tutorials and just can't get past this one spot. See the error below ModuleNotFoundError: No module named 'dj_database_url' So I have manually created the static file directories in the project, I ran the python manage.py collectstatic --noinput command locally and it did its job and put the files in the STATIC_ROOT directory. I also changed things out and the module name will change based on the order of the requirements.txt I really have no idea what I can do to fix this. Any help would be greatly appreciated. It feels like it is a really simple fix but I don't know what it is. -

Problems with CustomUser model in Django
I am new using Django and I am trying to build a project that requires to use a Custom User Model. I have encountered many problems on my way, tried to resolve them on my own but after more than one week I am exhausted, so I ask for your help. I think the main problem is that I don't understand well how to create a CustomUser model. I need a user to have many fields (E.g full_name, mobile_phone, etc), but one of the critical fields which I've had problems is: division_id (wich is a foreign key for a model created in another app named 'divisions'). I've had a lot of problems because there is no any migration yet (its supposed that your first migration must be when you created your custom user model), so there isn't any values in 'division' model. Is it possible to refer a foreign key in that case considering that the model referred isn't created yet? I mean, the first migration can create a custom user model and a division model simultaneusly, or what I have to do? Another problem I have, is that when I'm trying to refer the Division model into my CustomUser … -
How to import file from a nested directory with django
I am building a django web application. For the code, I have a few helper functions I am trying to import, but django gives me a ModuleNotFoundError.

I tried adding the __init__.py file to the models_helper directory, but this does not solve the issue. I also tried adding the path to sys.path. That, too, does not seem to solve the problem. My imports in the tasks.py files are as follows. from models_helper.yahoo_stock_data import YahooStockData from models_helper.data_handler import DataHandler from models_helper.arma import AlgoARMA The error I get is as follows.

Django modeling a supplier DB with different products. Unable to figure out supplier_product relation table
I am having a Django project where I have a supplier and multiple products which are vastly different from each other. The products are called resources. Because they are very different I cannot have a product table and therefore, don't know how to make the supplier_product model through which I can fetch all the products related to supplier. Here are example models: class Company(models.Model): ...... #some common fields class Supplier(Company): # delivery_time = "3 weeks" delivery_time = models.CharField(max_length=255, blank=True, null=True) # minimun order quantity MOQ = models.FloatField(blank=True, null=True) moq_unit = models.CharField(max_length=255, blank=True, null=True) billing_address = models.ForeignKey( .... ) shipping_address = models.ForeignKey( .... ) There are some more fields in the supplier. Here are the resources: class Resource(models.Model): ....... #some common fields class Part(Resource): code = models.CharField(max_length=255, unique=True, blank=True, null=True) supplier = models.ForeignKey( Company, related_name="supplier_part", on_delete=models.SET_NULL, null=True, blank=True, ) country = models.CharField(max_length=255, blank=True, null=True) class Fuel(Resource): code = models.CharField(max_length=255, unique=True, null=True, blank=True) color = models.CharField(max_length=255) supplier = models.ForeignKey( Company, related_name="supplier_fuel", on_delete=models.SET_NULL, null=True, blank=True, ) Now the problem is how can I make a SupplierProduct models with (supplier, product) field.
