Create HTTP response errors and timeouts for testing? [closed]
I suspect a counter outside scope could be used to do this. Does anyone know if there is a particular convention or interceptor to do the same? I’ll be using Flask or Django frameworks. -
Test a model property in django using Pytest
I want to test the output of a model property in django using pytest[pytest-django]. models.py: class TravelFriend(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name="travel_friends") name = models.CharField(max_length=100) birthdate = models.DateField() def __str__(self): return self.name @property def age(self): days_in_year = 365.2425 age = int((date.today() - self.birthdate).days / days_in_year) if age >= 18: return "18+" else: return age basically the property return the age in years or the string '18+' if the age is more than 18 test_models.py: class TestTravelFriend: def test_travelfriend(self): """The family member is connected to a user and have valid attributes""" travel_friend = TravelFriendFactory() assert travel_friend is not None assert str(travel_friend) == travel_friend.name assert travel_friend.user is not None assert travel_friend.name is not None assert travel_friend.birthdate is not None assert travel_friend.age is not None factories.py: class TravelFriendFactory(factory.django.DjangoModelFactory): class Meta: model = "accounts.TravelFriend" user = factory.SubFactory("accounts.tests.factories.CustomUserFactory") birthdate = factory.Faker( "date_of_birth", maximum_age=25, ) I want to test that the output of the property is correct but if i put an if statement in the test like this year = -int(travel_friend.birthdate.year - date.today().year) if year < 18: assert travel_friend.age == year else: assert travel_friend.age == "18+" but in order to have 100% coverage I need to test this last part of code which I don't … -

Adding fields to ModelForm programatically not showing in django admin
I have a usecase where I want to add fields to a modelform in django admin, but when trying to add them in the __init__function like this: class PackageFileInlineForm(forms.ModelForm): class Meta: model = File fields = '__all__' def __init__(self, *args, **kwargs) -> None: super().__init__(*args, **kwargs) self.fields['test'] = forms.CharField(max_length=100) Nothing shows up in the form. However if I do the form like this: class PackageFileInlineForm(forms.ModelForm): test = forms.CharField(max_length=100) class Meta: model = File fields = '__all__' Why does the init version not work? -
Django Multiple User's Authentication, SignUp Serializer and Views
I'm practicing creating multiple user types of authentication (in this scenario, Client and Driver like Uber) along with JWT. Currently, I am trying to write the SignUp Serializer for each corresponding user type (or if there is any more elegant way to do this), after signing up, I would love the user to have a Token. Please have a look at my code and teach me how or what could I do. This is my models from django.db import models from django.utils import timezone from django.contrib.auth.models import AbstractUser # Create your models here. class User(AbstractUser): email = models.EmailField(unique=True) # vars to check whether user is client or driver is_client = models.BooleanField(default=False) is_driver = models.BooleanField(default=False) class Client(models.Model): is_staff = False user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) def __str__(self): return self.user.username class Driver(models.Model): is_staff = False user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) def __str__(self): return self.user.username My serializers.py (kinda messy) from rest_framework import serializers from base.models import User, Customer, Technician from rest_framework_simplejwt.tokens import RefreshToken # Serialize data from db class UserSerializer(serializers.ModelSerializer): name = serializers.SerializerMethodField(read_only=True) _id = serializers.SerializerMethodField(read_only=True) isAdmin = serializers.SerializerMethodField(read_only=True) class Meta: model = User fields = ['id', '_id', 'username', 'email', 'name', 'isAdmin'] def get__id(self, obj): return obj.id def get_isAdmin(self, obj): return obj.is_staff def … -

Django IntegrityError: duplicate key value violates unique constraint ... DETAIL: Key ... already exists
In a Django app with Postgres db i have a model named Block. It is used in other models as ForeignKey class Block(models.Model): name = TranslatedField(models.CharField(max_length=200),) color = models.IntegerField(choices=BLOCKCOLOR_CHOICES, null=True, blank=True) blocktype = models.CharField(max_length=20, choices=BLOCKTYPE_CHOICES, default="break") def save(self, *args, **kwargs): self.name = self.name.capitalize() return super().save(self, *args, **kwargs) def __str__(self): return f"{self.name} ({self.blocktype})" I use django-translated-fields to translate the name in 4 languages. These are the relevant lines in admin: class BlockAdmin(TranslatedFieldAdmin, admin.ModelAdmin): pass admin.site.register(Block, BlockAdmin) I can create a new instance of Block in the admin interface and also in the view. When I edit the model and try to save I get the above mentioned error. It happens in the admin interface and in the view as well. I can manually delete the model and create a new one, it gets a new id. It doesn't matter if the model is already bound via ForeignKey to another model or if it's standalone. Can somebody give me an advice? Thank you in advance! I have tried manipulating the id in the database, as a final solution I have also deleted the database completely. It happens again. I have a feeling that it has something to do with the django-translated-fields package. … -
ORA-00955 error with django migrate but no tables in Oracle database
I'm trying to deploy a Django application on an Apache webserver and Oracle DB. When I get to trying to create the database tables using manage.py migrate I get an error ORA-00955: name is already used by an existing object. It doesn't tell me what the object is (which is frustrating). Looking at the database I don't have any tables in my schema. I have run migrate more than once due to an earlier failure, but there's nothing there that I can see (I'm looking at the database in DBeaver). I've tried SELECT table_name FROM all_tables WHERE owner = 'MYUSERNAME'; but that doesn't return anything. Is there some way to find out what the blocking object is? Is there some way to make migrate force its way through? What am I missing that means I can't see the tables that the database sees? -

Django Python not redirecting to login page after clicking sign up button

Django - How to improve performance when model contains a large JSONField?
I am working on trying to figure out how to enhance performance when filtering on a queryset that has a JSONField with large data (thousands of lines). Even when querying and returning an estimated 100 objects, the return is extremely slow. 10-20 seconds. I have come to realize that the issue is the JSONfield, and the fact that large datasets are being stored in this field. I was reading about Djangos .only() and .defer() methods, because I don't need any data in this JSONField, but the performance seems to be the exact same without using these methods. I am just looking for some guidance on how to improve some performance here. -

Warning - Certain functionality requires requests_html, which is not installed
when I run my django server everything works fine. However right before the normal prompt that comes from running the server, I get this message Warning - Certain functionality requires requests_html, which is not installed. Install using: pip install requests_html After installation, you may have to restart your Python session. Warning - Certain functionality requires requests_html, which is not installed. Install using: pip install requests_html After installation, you may have to restart your Python session. And then my django server goes on and runs fine. I'm worried that when I deploy my website this error will be a problem. Btw I know where this is coming from. I'm using yahoo_fin and requests_html is a dependency, however I'm not using and won't use the yahoo_fin methods that require this dependency, so I guess what I'm asking is for a way to ignore this random Warning. I've tried installing the requests_html library but I still get the same error, even after I restart my Python session like the message says. -

Django Template Error: KeyError: "'test'=='test'" (string == string)
This one has even stumped Chat GPT who thinks there is nothing wrong with my code. I will slowly dissect my code till I get to the bottom of what is happening but given how bizarre it is, I wanted to document it here. I am building using Django and have a Django template. The main template calls a second template and it's on that second template the issue is happening: {% include "kb/select_file_dialog.html" %} {% if 'test'=='test' %} <script> var dialog = document.getElementById('my_modal_2'); dialog.showModal(); </script> This gives me the error: KeyError: "'test'=='test'" I have no idea why it thinks it's working with a dictionary. Without the problematic line {% if 'test'=='test' %} the code runs fine. -

Google Cloud Storage Authentication Issue with Django using google-auth
I am facing an authentication issue while trying to use Google Cloud Storage with Django. I have set up my Django project to use google-auth library for authentication with other Google APIs, but when I try to use Google Cloud Storage, I get the following error: This library only supports credentials from google-auth-library-python. See https://google-auth.readthedocs.io/en/latest/ for help on authentication with this library. Steps Taken: I have set up my Django project with the necessary configurations, including installing google-auth library. I have defined the GS_CREDENTIALS variable in my Django settings to store the path to the service account JSON file. I am using the storages.backends.gcloud.GoogleCloudStorage storage backend in Django settings to handle media and static files storage on Google Cloud Storage. Django settings.py GS_CREDENTIALS = os.environ.get('GOOGLE_APPLICATION_CREDENTIALS') STATICFILES_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' Expected Behavior: I expect the google-auth library to handle the authentication with Google Cloud Storage, just as it does with other Google APIs in my Django project. Actual Behavior: When trying to use Google Cloud Storage, the mentioned error is raised, indicating that the library only supports credentials from google-auth-library-python, even though I have google-auth installed and working correctly with other APIs. Additional Information: I have verified that google-auth …
