React Django Google Sign In

In django, how can I have two different methods for instantiating the same model?
I am building a system to register parts for manufacturing (for context: temperature sensors). As I'm dealing with many different subtypes of actual physical parts, I'm using django-polymorphic to define the models for the actual temperature sensors: class TempSensor(PolymorphicModel): """Abstract model for temperature sensors"""" part_number = models.OneToOneField(Part, on_delete=models.CASCADE) class TempSensorA1(TempSensor): calibration = models.CharField(max_length=1, choices=Calibration.choices) junction = models.CharField(max_length=1, choices=Junction.choices) def __str__(self): return f"A1-{self.calibration}{self.junction}" class TempSensorB1(TempSensor): calibration = models.CharField(max_length=1, choices=Calibration.choices) termination = models.CharField(max_length=1, choices=Termination.choices) def __str__(self): return f"B1-{self.calibration}{self.termination}" The Part model acts as a container for the TempSensor instances. This lets me assign a simpler consecutive part number and associate them with orders. class Part(models.Model): part_number = models.AutoField(primary_key=True) order = models.ManyToManyField(Order, through="OrderDetail") production_notes = models.TextField(blank=True) sales_notes = models.TextField(blank=True) class Meta: ordering = ["part_number"] Right now, I have the django admin interface working as expected. When adding a new Part instance, I can add a TempSensor, select the correct child type and input the fields manually, all through an inline. This works great when working from raw specifications. However, since model codes are often provided directly, I also need to be able to instantiate TempSensor directly from the model code. To solve this, I've created a create_from_model_code method that takes the model code, … -

Django signals and proxy models
From what I tested, if I have a model (Vehicle) and 2 proxy models (Car and Bike, proxies of Vehicle) and I want to trigger a post_save signal, the signal will be triggered only by the save operation on the Vehicle model. I was expecting the signal to be triggered by the save operation also for Car and Bike because it's the same db table. Does anyone knows where I can find an explanation for this behavior? -

Django "Unknown column 'userdata.password' in 'field list'" >> fix WITHOUT deleting existing table?
I have a table that is now called "userdata" in an AWS RDS mysql database. In a past migration, the table had a different name, "users". Now, with the new name, I cannot access the data in the table. I get the error >> 1054, "Unknown column 'userdata.password' in 'field list'". Other Stack Overflow posts suggest dropping the table and starting over to fix the problem.

Django broken pipe during authentication form post
I am trying to develop a website with Django 4, and I am puzzled by my authentication system behaviour. I am trying to develop the sign up feature, and it has not worked yet, my auth_user table is still empty. When I try signing up using Firefox, the POST request generates this error : Broken pipe from ('127.0.0.1', 52245) - when retrying, the numbers inside the parenthesis change, and I don't know the meaning of these and couldn't find it. My request seems to not be handled as the database stays empty. When I try the same thing using Edge, the database stays empty too, but the POST request generates no error. I have read that broken pipe errors were errors on the client part (the client closes the connection without waiting for the server's response), but I can't see where I need to alter things to solve that... I have also read about this happening when using ajax requests, and the way to solve it was to make the input a button type and not a submit type, but this is not an ajax request. I tried doing that because you never know, but having a button instead of … -

Restrict access to multiple admin sites per user/group in Django
When using multiple admin sites in Django i want to seperate the depth / complexity of information availabe in different sites. The generally works but a user can still login to the other sites and see more than he is supposed to because he has view permission to a model. Imanine having morve levels between staff and superuser like "is_staff_trainee", "is_staff_junior", "is_staff_senior" and "is_staff_bigboss". They all have their own admin sites. On some models the admin is the same for all of them, so i register the same ModelAdmin to all of the sites. But on some model, let's say "Drinks", they all get their own DrinkAdminTrainee, DrinkAdminJunior, DrinkAdminBigBoss, you get it. A Trainee has most of the fields read only, a Junior can edit most of them on the edit page, a senior gets additional information about e.g. the price calculation an can choose from more expensive ingredients to create his drinks and the Big Boss can also see all the old (long deactivated) Drinks from the Past. That works perfectly. But any Trainee can still login to the Big Boss Admin site if he kows the URL and also use it because he still "is_staff" and has view … -

User 1 is on the /houses/5/edit page and is currently editing the house with ID 5. Now I want to block editing from the house with ID 5 for other users. Only one user should be able to access the editing page of a particular house at a time. All other users should see on the detail page of the house with ID 5 (/houses/5/) that the house is already being edited. Only when user 1 leaves the page /houses/5/edit, another user should be able to edit the house. I want to have this blocking mechanism because otherwise changes to the house could be overwritten by another user. So the mechanism should be similar to the blocking mechanism in Wordpress CMS for blocking a page or post. How can I implement this? I already use django-channels for push notifications. My idea was to use websockets for blocking. Also, I saw that django-redis offers a blocking mechanism. However, I still have no idea how to implement my requirements with it and whether these technologies are the best … -
Understanding and setting the order of Django migrations
I have models that look like: class FubarCategory(models.Model): class name = models.CharField(max_length=32) class FubarScenarioType(models.Model): class name = models.CharField(max_length=32) class FubarProduct(models.Model) category = models.ForeignKey( FubarCategory, on_delete=models.DO_NOTHING, related_name="products" ) scenario = models.ForeignKey( FubarScenarioType, on_delete=models.DO_NOTHING, related_name="products" ) class FubarTransaction(models.Model): product = models.ForeignKey( FubarProduct, on_delete=models.DO_NOTHING, related_name="transactions" ) I expect a brand new migration to look like: Migrations for 'fubar': apps/fubar/migrations/0001_initial.py - Create model FubarCategory - Create model FubarScenarioType - Create model FubarProduct - Create model FubarTransaction Instead, I see this: Migrations for 'fubar': apps/fubar/migrations/0001_initial.py - Create model FubarCategory - Create model FubarProduct - Create model FubarScenarioType - Add field scenario_type to Fubarproduct - Create model FubarTransaction Why is FubarScenarioType being created after FubarProduct instead of before? -
How to authenticate selenium before running `pytest`?
I'm using pytest-django with selenium for testing features. Some features require being logged in. Here's how I create a test user: import sqlite3 import uuid import pytest from django.conf import settings from django.contrib.auth.models import User from django.core.management import call_command from selenium.webdriver import Chrome, ChromeOptions @pytest.fixture(scope='session', autouse=True) def browser(): options = ChromeOptions() options.add_argument('--no-sandbox') options.add_argument('headless') chrome = Chrome(options=options) yield chrome chrome.close() @pytest.fixture(scope='session') def test_user(): return {'username': uuid.uuid4().hex[:10], 'password': uuid.uuid4().hex} @pytest.fixture(scope='session') def django_db_setup(django_db_blocker, test_user): db_path = settings.BASE_DIR / 'test-db.sqlite3' sqlite3.connect(db_name := db_path.as_posix()) settings.DATABASES['default']['NAME'] = db_name with django_db_blocker.unblock(): call_command('migrate', '--noinput') User.objects.create_user( username=test_user['username'], password=test_user['password'], email=f'{test_user["username"]}@test', ) Now that a test user is created, I need to use it with selenium before tests that require logging in. A typical test class looks like: class TestSomeUrl: def test_feature1(browser): ... def test_feature2(browser): ... But I need to login first. What would be the proper way to do so? I tried first to login inside the browser fixture by doing: @pytest.fixture(scope='session', autouse=True) def browser(live_server, test_user): options = ChromeOptions() options.add_argument('--no-sandbox') options.add_argument('headless') chrome = Chrome(options=options) chrome.get(f'{live_server}/login') browser_login(chrome, test_user) yield chrome chrome.close() But I get a Bad Request (400) because live_server seemingly has no started yet, otherwise it should get f'{live_server}/login' without issues. Answers here are outdated and do not work anymore. …
