simple song CRUD application with a music app
simple song CRUD application. In our models.py file inside the “musicapp” application we created, you are expected to add the following Models and Attributes. Model: Artiste, Song, Lyric Attributes for “Artiste” : first_name, last_name, age Attributes for “Song”: title, date released, likes, artiste_id Attributes for “Lyric”: content, song_id As you might have guessed, there is a relationship between all three Models. An Artiste can have multiple songs, and a song can have multiple lyrics.A song must only belong to one Artiste and a lyric must only belong to a song. -
How to authenticate a user in django unit test when rest framework's DEFAULT_AUTHENTICATION_CLASSES is 'JWTStatelessUserAuthentication'?
I had a Django project with the following settings: 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication', ] and in the unit testing phase, I used to assign a Token to an existing user to authenticate the user: def setUp(self): self.user = User.objects.create(username='u1') self.client = APIClient() token = Token.objects.create(user=self.user) self.client.credentials(HTTP_AUTHORIZATION="Token " + token.key) but now, in my current project, I don't authenticate users, instead, I use these settings: 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework_simplejwt.authentication.JWTStatelessUserAuthentication', ], SIMPLE_JWT = { 'ALGORITHM': '...', 'SIGNING_KEY': '...', } and user authentication stuff is in another project and authentication tokens have an expiration time! How can I authenticate a user in my unit testing?! Is there any solution to this issue? -
How to use dj-rest-auth with many clients
I'd like to have many different clients be able to access my django website (more specifically its API) but I'm not sure how to do this with django-allauth, dj-rest-auth and simplejwt. My current client app is using the built in django template engine and is set up with django-allauth for social authentication (Google etc). It's working using the documented installation recommendations. I would now like to create different types of clients that aren't using the django template engine (e.g. Angular, Vue, flutter mobile etc) but I'm confused how dj-rest-auth is used so that it scales to support any number of client types. Using Google social sign in as an example, when I create a new client, I have to register a new redirect_uri specific to that client. To test this all out, I created a simple flask app with a single link so that I can retrieve a "code/access_token" before sending it to my Django app. The link is created using the following... var codeRequestUrl = `https://accounts.google.com/o/oauth2/v2/auth?\ scope=email&\ access_type=offline&\ include_granted_scopes=true&\ response_type=code&\ state=state_parameter_passthrough_value&\ redirect_uri=http%3A//127.0.0.1:5000/callback&\ client_id=${clientId}`; ...and the code is retrieved at the '/callback' endpoint in flask... @app.route("/callback", methods=['GET']) def redirect(): code = request.args.get('code', '') req = requests.post('http://127.0.0.1:8000/api/dj-rest-auth/google/', data={'code':code}) return "done..." ...from … -

filtering an queryset in an Inline object in Django Admin
The contest is an inventory app of an e-commerce project. As expected, there's a Product model. In an attempt to normalize the DB schema, I have created these additional models: ProductType (ForeignKey relationship in Product) ProductSpecification (a FK in ProductType) ProductInventory (with a FK to Product) ProductSpecificationValue (FK to both ProductSpecification and ProductInventory) I hope this makes sense - each ProductType has many Products, and also many Specifications. ProductInventory (suggestions of a better name are welcome), with a FK to product, is a model with SKU and quantity fields. And the fun part - it has a ManyToMany relationship to ProductSpecification, through ProductSpecificationValue. Now the part where I am lost is adding this whole thing to Django Admin site. I can create ProductTypes and Products without any problem, and a ProductTypeAdmin has an inline to add those specs:. @ admin.register(ProductType) class ProductTypeAdmin(admin.ModelAdmin): inlines = [ ProductSpecificationInline, ] The problem starts when I try to add a ProductInventory entity. Because it's associated with a given ProductType, I want to limit the choice of inlines to only those which are related to the same ProductType. class ProductSpecificationValueInline(admin.TabularInline): model = ProductSpecificationValue def get_formset(self, request, obj=None, **kwargs): # obj is always the current Product … -
How to retrieve all Variants of a single Product in a single JSON object per Product- Django Rest Framework
The way I am doing it is like in getProductList function in my views.py and it is giving me each product with its variants in different objects like so: JSON: [ { "prod_id": { "id": 3, "prod_name": "CRUISER-149S-DEERCALF", "category": 2 }, "size_id": { "id": 2, "name": "26" }, "color_id": 2, "image_id": { "id": 10, "prod_image": "/media/products/IMG_7617_ftgqoa.jpg" } }, { "prod_id": { "id": 3, "prod_name": "CRUISER-149S-DEERCALF", "category": 2 }, "size_id": { "id": 3, "name": "27" }, "color_id": 2, "image_id": { "id": 10, "prod_image": "/media/products/IMG_7617_ftgqoa.jpg" } } ] Is there a way to maybe make it more optimized? like have only one object that has all the info of a single product like size for example can be a property with values of all sizes in it like size: [26, 27] instead of a different object if a size is different. models.py class Products(models.Model): prod_name = models.CharField(max_length=200) category = models.ForeignKey(Categories,null=True, on_delete=models.SET_NULL) def __str__(self): return '%s'%(self.prod_name) class Variants(models.Model): prod_id = models.ForeignKey(Products, on_delete=models.CASCADE) size_id = models.ForeignKey(Size, null=True, on_delete=models.SET_NULL, related_name='variants') color_id = models.ForeignKey(Color, null=True, on_delete=models.SET_NULL, default='') image_id = models.ForeignKey(Image,null=True, on_delete=models.SET_NULL, default='') def __str__(self): return '%s %s %s %s %s %s %s'%(self.id , self.prod_id, self.size_id, self.image_id, self.color_id, self.quantity, self.price) serializer.py class ProductsSerializer(serializers.ModelSerializer): # variants = serializers.StringRelatedField(many=True) … -

How to get a django instance to have one to many users relation

What is the best way to make logs with React and Python(Django)?
If I have a frontend with React and a backend with Python Django, how can I integrate custom logs? If I need to store which functions were pressed and when? Example: We have a PostgreSQL database and there is a file called Logs.txt. When the user opens a specific route, we need to save the time and route name in this file. Also, if there are some buttons that run some functions, we also need to save the time and function name in this log file. Do I need to every time to make a simple request to the backend to save new data about users' pressed history? Or is there some better approach? -
Django doesn't process POST request's payload from axios

Celery Beat sending all periodic tasks as due on restart even if they have just run
I am running a celery worker and celery beat with DatabaseScheduler. I am running these on Heroku along with a django web application. They are being used to send emails and texts at regular intervals, Once per day at midnight for emails and 730am for texts. I have defined the tasks manually using a chrontab in Periodic Tasks table, but I have also tried defining them in the codebase using celeryapp.conf.beat_schedule, both behave the same. The tasks look like this periodic tasks in django admin The issue I am having is that Heroku restarts its dynos once per day as a policy, and when this happens, the celery beat dyno runs my periodic tasks for some reason. The debug log reads "Scheduler: Sending due task" as if it is normal, whether they are due then or not. I do not know why this is happening. I have celery results running as well with postgres backed task results and that looks like this, where I have the tasks running at the correct times (midnight and 730am), but also at some random time when heroku restarts the dynos. How can I stop the tasks from running when this restart happens? Why are … -

Here are my classes class City(models.Model): name = models.CharField(max_length=10, null=True) created_at = models.DateTimeField(auto_now_add=True, null=True, blank=True) updated_at = models.DateTimeField(auto_now=True, null=True, blank=True) class PowerSource(models.Model): source = models.CharField(max_length=8) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Manufacturer(models.Model): manufacturer = models.CharField(max_length=45) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class CarModel(models.Model): model = models.CharField(max_length=45) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) manufacturer = models.ForeignKey(Manufacturer, related_name='car_models', on_delete=models.CASCADE) class Car(models.Model): color = models.CharField(max_length=10, null=True) year = models.IntegerField(null=True, validators=[MinValueValidator(datetime.today().year-120), MaxValueValidator(datetime.today().year+1)]) num_passengers = models.IntegerField(validators=[MinValueValidator(1)], null=True) transmission = models.CharField(max_length=9, null=True) status = models.CharField(max_length=4, null=True) price = models.IntegerField(validators=[MinValueValidator(1)], null=True) bhp = models.IntegerField(null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) city = models.ForeignKey(City, related_name='cars', on_delete=models.CASCADE) power_source = models.ForeignKey(PowerSource, related_name='cars', on_delete=models.CASCADE) model = models.ForeignKey(CarModel, related_name='cars', on_delete=models.CASCADE) For example, if I choose a manufacturer and leave other fields empy I should get all cars from that manufacturer regardless of color, year, etc. However, I … -
Multistepform with multiple images Django

Custom django CharField returns a Path instance
I have a model that tracks details of files (but does not serve the file itself). Currently, I am using a CharField to store the path, but it gets cumbersome to constantly convert that field to a Path instance. Model looks like this: class MyFile(models.Model): path = models.CharField(max_length=100) checksum = models.CharField(max_length=32) content_last_updated = models.DateTimeField(null=True) @property def is_image(self) -> bool: return Path(self.path).suffix == '.jpg' I tried to define a custom Field by subclassing CharField class PathnameField(models.CharField): def from_db_value(self, value, expression, connection): return Path(value) if value is not None else value If I substitute this field class in the model, nothing breaks but the field type is still a str. afile = MyFile.objects.create(path=Path('foo/bar.txt'), checksum='000') afile.refresh_from_db() assert isinstance(afile.path, Path) Has anyone tried this? -
