How to identify and authenticate the right "user" when we use Django (Existing proj) for authentication and FastAPI (new feature) for API's?
Hello guys I have an existing Django project which has certain features and also has user data. For certain features, users use the API served through Django, but since there is a need for new feature which needs to be implemented through FastAPI, I need to have the same users authenticate or to be recognized by FastAPI (as this is the same user in Django) to save an action corresponding to user in the db. How to achieve that? How do I store the user data, like user_id and username for each user safely? How to properly design the database table? Please do let me know, how to start. Thank you. -

Creating multiple test databases in Django TestCases
I wanted to create multiple test databases, so I could check if my synchronizing script is working properly. I have added them to Django settings like this: DATABASES = { "default": { "ENGINE": env.str("DB_ENGINE"), "NAME": env.str("name[1]"), "USER": env.str("DB_USER"), "PASSWORD": env.str("DB_PASSWORD"), "HOST": env.str("DB_HOST"), "PORT": env.str("DB_PORT"), "TEST": { "NAME": 'name[1]', } }, "name[2]": { "ENGINE": env.str("DB_ENGINE"), "NAME": "[name1]", "USER": env.str("DB_USER"), "PASSWORD": env.str("DB_PASSWORD"), "HOST": env.str("DB_HOST"), "PORT": env.str("DB_PORT"), "TEST": { "NAME": "name[2]", } }, "name[3]": { "ENGINE": env.str("DB_ENGINE"), "NAME": "name[3]", "USER": env.str("DB_USER"), "PASSWORD": env.str("DB_PASSWORD"), "HOST": env.str("DB_HOST"), "PORT": env.str("DB_PORT"), "TEST": { "NAME": "name[3]", } }, } This is how my test for sake of testing looks like: class SyncTestCase(TestCase): def setUp(self) -> None: self.client = Client() def test_func_tester_client(self): bitbucket_db_setup.main() response = self.client.get("/v1/devices/?name=a", SERVER_PORT=8000) print(response.content) self.assertEqual(200, 200) But when I run it, it only creates DB for 'default' alias: Creating test database for alias 'default'... *DB_SMTH are imported names from environment and name[x] are just names -

How to remove the name "Queryset" from queryset data that has been retrieved in Django Database?
we all know that if we need to retrieve data from the database the data will back as a queryset but the question is How can I retrieve the data from database which is the name of it is queryset but remove that name from it. maybe I can't be clarified enough in explanation so you can look at the next example to understand what I mean: AnyObjects.objects.all().values() this line will back the data like so: <QuerySet [{'key': 'value'}] now you can see the first name that is on the left side of retrieving data which is: "QuerySet" so, I need to remove that name to make the data as follows: [{'key': 'value'}] if you wonder about why so, the abbreviation of answer is I want to use Dataframe by pandas so, to put the data in Dataframe method I should use that layout. any help please!! -

Why can I access Django Development Server from localhost (vscode)?
Okay so I've just started to learn Django and I've been using vscode to SSH connect to my remote development machine and I save my changes on the remote machine. But when I run the development server, I access it on my localhost network, not from the remote IP. How is this possible given I ran the command manage.py runserver 9000 from the remote machine? Is this something to do with VSCode? Cheers -
Django charfield choices compatibility
I've a model which has field choices. In the saving case i wanna make sure that value is in that choices list. class Foo(models.Model): GENDER_CHOICES = ( ('M', 'Male'),('F', 'Female'), ) gender = models.CharField(max_length=1, choices=GENDER_CHOICES) But when i try to save with value out of choices , it saves that value. foo = Foo(gender = "A") foo.save() Yes i can control it in code like if value in genderlist: but in my project that will take so time to add this control in every usage of choices saves. Is there any chance to control it in MODEL ( overriding save method or some option for field or etc ) ? -
Django how to test whether password validators are being used
My Django settings file contains the following password validators: AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] I am using django allauth and django restauth to set up authentication endpoints. If I post to the registration endpoint with a password that is too short, too common, or only numeric, I receive and appropriate error message. Here's an example with all three: { "email": "toasterffs@gmail.com", "password1": "1223", "password2": "1223" } { "password1": [ "This password is too short. It must contain at least 8 characters.", "This password is too common.", "This password is entirely numeric." ], } When I post to the registration endpoint with a password that is the same as the email address, I receive no error. I need to debug this but where to even start? I there somewhere I can inspect which validators are actually called? Can I monkey patch the validator and put some logging in to see where things are going wrong? Is there a signal? some other hook? Thanks -

How to Django ORM update() multiple values nested inside a JSONField?
I have a Django JSONField on PostgreSQL which contains a dictionary, and I would like to use the queryset.update() to bulk update several keys with values. I know how to do it for one value: from django.db.models import Func, Value, CharField, FloatField, F, IntegerField class JSONBSet(Func): """ Update the value of a JSONField for a specific key. """ function = 'JSONB_SET' arity = 4 output_field = CharField() def __init__(self, field, path, value, create: bool = True): path = Value('{{{0}}}'.format(','.join(path))) create = Value(create) super().__init__(field, path, value, create) This seems to work - with some gaps as per my other question - like this: # This example sets the 'nestedkey' to numeric 199. queryset.update(inputs=JSONBSet('inputs', ['nestedkey_1'], Value("199"), False)) But if I now wanted to update a second nestedkey_2 inside the same inputs, I obviously cannot use the inputs argument twice like this: queryset.update(inputs=JSONBSet(...'nestedkey_1'...), inputs=JSONBSet(...'nestedkey_2'...)

How to Django ORM update() a value nested inside a JSONField with a numeric value?
I have a Django JSONField on PostgreSQL which contains a dictionary, and I would like to use the queryset.update() to bulk update one (eventually, several) keys with a numeric (eventually, computed) values. I see there is discussion about adding better support for this and an old extension, but for now it seems I need a DIY approach. Relying on those references, this is what I came up with: from django.db.models import Func, Value, CharField, FloatField, F, IntegerField class JSONBSet(Func): """ Update the value of a JSONField for a specific key.

Can ngx_http_auth_basic_module be used for backends on different ports?
I can't add authentication system for the new backend for some reasons, so I want to check user authentication status from the old backend and give access for the new backend new endpoints if this user logged. So, can ngx_http_auth_basic_module be used for backends on different ports? Or is there a better practice?
