Hoping someone can help me debug an issue I have using django-python3-ldap.

Relation does not exist when running Django Unit Tests
I am having trouble running unit tests in my django app when it is running through Jenkins. I have a CI/CD pipeline which runs python manage.py test which is currently failing with the error: django.db.utils.ProgrammingError: relation "auth_user" does not exist.

How to configure PingFederate SSO with SAML for application where frontend is written in react and backend Puthon django
I'M WORKING ON A PROJECT THAT INTEGRATES PING FEDERATE SSO USING SAML FOR AUTHENTICATION, WITH A FRONTEND DEVELOPED IN REACT AND A BACKEND IN DJANGO (PYTHON). I WOULD APPRECIATE YOUR INSIGHTS ON THE BEST PRACTICES TO IMPLEMENT THIS SETUP Current Understanding of the Authentication Flow: The user initiates a request to the frontend. The frontend redirects the user to the Identity Provider (IdP). The user authenticates on the IdP's website. The IdP sends a signed SAML assertion back to our frontend. Our frontend then forwards this SAML assertion to the backend for processing. Questions: Is this flow correct, or is there a more recommended approach for integrating SAML with a React/Django application? What libraries or tools would you recommend for implementing this flow in both React and Django? How should the backend validate the SAML assertion received from the frontend? I'm particularly interested in any best practices, libraries, or patterns that would make this implementation as secure and efficient as possible. Any advice or resources you could share would be greatly appreciated. -
Django Test Fails with OperationalError on Tenant Deletion in Multi-Tenant PostgreSQL Setup
I'm encountering a specific issue when running test cases in a Django project that involves a multi-tenant PostgreSQL database setup. The process I'm testing is tenant deletion, and it's noteworthy that this error only appears during tests, while the actual application runs without any issues in a actual run. Error Messages: During the test execution, I'm hit with two errors in sequence: django.db.utils.OperationalError: cannot DROP TABLE "model_name_1" because it has pending trigger events django.db.utils.InternalError: current transaction is aborted, commands ignored until end of transaction block Detailed Context: The issue manifests when running a Django test that tests the deletion of a tenant and its associated data. Specifically, the errors are triggered at the line where the tenant is deleted using tenant.delete(force_drop=True). The test case sets up data for models that include foreign key relationships, and it is under these conditions that the errors are observed: def test_tenant_deletion(tenant, monkeypatch): with tenant_context(tenant): model_1.objects.create(name="Test date", process_id="process") model_2.objects.create(name="Test date", model_1=model_1.objects.first()) payload = { "eventId": "abcdef", "type": "DELETED", "tenant": {"tenantId": str(tenant.id)}, } event = Mock(link=Mock(source=Mock(address="delete_tenant")), message=Mock(body=json.dumps(payload))) listener = BTPMessageQueueListener(SOLACE_BROKER_URL, SOLACE_BROKER_USER, SOLACE_BROKER_PASSWORD) listener.on_message(event) assert not Tenant.objects.filter(id=tenant.id).exists() Observations: The operation tenant.delete(force_drop=True) proceeds without errors in a real run. The errors are specific to the testing environment, particularly … -

what should I choose : Django or Node.js? [closed]
I am a solo developer who has been freelancing for a year, and now I have a project related to CRM on which I am going to work in a team. One of my team members said, Let's go with Django, and the other said, Why don't we use Node?". I am comfortable with both and deciding which to choose! Here is the project outline: we get data from users, generate digital documents, agreements, quotations, and invoices, and mail them to the user accordingly. In short, this project is related to audit services. So, kindly let me know, guys, which stack I should choose with pros and cons. -
Django logging isn't working, despite having proper settings
Problem and background Hi, I have a Django project using Django 2.2.28, and python 3.5.2. The live site runs fine, except for one function I'm trying to debug. I've used logging before, but for some reason it's not working now. Here's my code... production_settings.py I call this file in wsgi.py. It's settings all work as they should, but LOGGING isn't. from .settings import * DEBUG = False LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': '/home/myuser/proj_container/debug.log', }, }, 'loggers': { 'django.request': { 'handlers': ['file'], 'level': 'DEBUG', 'propagate': False, }, }, } views.py import logging logging.basicConfig(level=logging.DEBUG) logger = logging.getLogger(__name__) def some_func(request): ... if some_condition: logger.debug('In some_condition block') elif some_other_condition: logger.debug('In some_other_condition block') What I've tried I've tried the above with just the settings in production_settings.py... Nothing shows up. Same as 1, but with logging imported and called at every important code block. I read the docs for logger.debug(), as well as this answer that I implemented above as you can see. I also reread the Django logging docs. I moved LOGGING from production_settings.py to settings.py... Yesterday I fixed a bug where django wasn't overriding the DATABASES variable in settings.py from production_settings.py, and was … -

Can't serve django App behind Apache + Nginx

I have a model with a boolean class MyModel(models.Model): ... current_measures = models.BooleanField( verbose_name=_("Is there any control and safety measures?"), choices=BOOLEAN_CHOICE, ) ... I have a form that should set a value on this field using either true or false values. class MyForm(forms.ModelForm): ... current_measures = forms.BooleanField( widget=WidgetRadioSelectCustomAttrs( RADIO_WIDGET_ATTRS, choices=Risk.BOOLEAN_CHOICE ), label=_("Is there any control and safety measures?"), label_suffix="", required=True, ) ... Everything works fine until I set required=True on my form field and send the value "False" to validation method. In this case it raises ValidationError('Current measures is required') As I found out while debuging, the issue is with validate method of forms.BooleanField. At first it runs the method to_python, witch converts my value 'False' (type string) to False (type bool). def to_python(self, value): """Return a Python boolean object.""" # Explicitly check for the string 'False', which is what a hidden field # will submit for False. Also check for '0', since this is what # RadioSelect will provide. Because bool("True") == bool('1') == True, # we don't need to handle that explicitly. if isinstance(value, str) and value.lower() in ("false", "0"): value = False else: value = bool(value) return super().to_python(value) Then the validate method of BooleanField class is being … -
how to verify Django hashed passwords in FastAPI app
So I have a Python project in Django and I'm trying to change it to FastAPI. The passwords in the database are already hashed (I'm using the same database from the Django project), the passwords in the database start with pbkdf2_sha256$260000$. I'm trying to do the login function, but I'm having trouble with the password, I get an error "raise exc.UnknownHashError("hash could not be identified") passlib.exc.UnknownHashError: hash could not be identified" when I insert the username and password in my fastapi login form. #Security config security = HTTPBasic() pwd_context = CryptContext(schemes=["pbkdf2_sha256"], deprecated="auto") async def login(request: Request): form = await request.form() username = form.get("username") password = pwd._context(form.get("password")) db = database.SessionLocal() user = db.query(models.User).filter(models.User.username == username).first() if not user or not pwd_context.verify(password, user.password): raise HTTPException(status_code=401, detail="Invalid username or password") token = create_jwt_token(user.id) response = RedirectResponse(url="/index", status_code=301) response.set_cookie(key="token", value=token) return response I'm trying to hash the password the user inserts so it can be verified with the hashed password in the database. I've also tried password = form.get("password"), and the error still pops up. This is the error: File "C:\Users\user\Desktop\VSPRojects\LoginFastapi\db\views.py", line 53, in login if not user or not pwd_context.verify(password, user.password): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\user\Desktop\VSPRojects\LoginFastapi\venv\Lib\site-packages\passlib\context.py", line 2343, in verify record = self._get_or_identify_record(hash, scheme, category) … -

How to implement an API database-connection to replace Django's functions
I have a project running in Django that handles all of my database actions through urls and views. I want to change this to Postgres and use an API that instead handles all of my database actions. This would be my first API so i'm not sure what the optimal process of designing it would be. So far I have just initialised a new project, I want to use Typescript and express.js.
