Use wagtail form into other templates
So I have created a Form with the Wagtail Form Builder and works well. Now I want to use the created from into other templates throughout my project.

Unable to get both access and refresh cookies in http only cookies
I'm creating a Django jwt authentication web app and I am trying to get both access and refresh tokens via HTTP-only cookies. But the front end can only get the refresh token, not the access token so I can't log in.

Not having write permissions for a file in a docker container
Every time I want to edit and save a file using a text editor like Sublime Text or VS Code, it requires my password. The files are part of a Django project in a docker container. Only the root user has write permissions. How can I set this so it doesn't require password? Also there's a lock icon on the project folders that have this problem. I tried adding my user to docker group to solve this problem but it didn't resolve. -
Is there any way in Python to run code with parameters from string variable?
I'm developing website with interactable algorithms. The problem is that i get code as string from database and i need to execute it with parameters that came from user interface. Is there any Python library that can solve this problem? I'm new to Python and Django and I don't really know is this possible or not. Example of code: class CombinationColex: def __init__(self, n, k): self.total_elements = n self.combination_size = k self.combination_array = [0] * (self.combination_size + 1) self.combination_array[self.combination_size] = self.total_elements + 2 self.first() def first(self): for i in range(self.combination_size): self.combination_array[i] = i def next(self): if self.combination_array[0] == self.total_elements - self.combination_size: self.first() return self.combination_size j = 0 while self.combination_array[j + 1] - self.combination_array[j] == 1: self.combination_array[j] = j j += 1 self.combination_array[j] += 1 return j def data(self): return self.combination_array[:-1] def Start(self): while True: for i in range(self.total_elements): present = i in self.data() print("1" if present else "0", end="") print() if self.next() == self.combination_size: break combination_generator = CombinationColex(n, k) combination_generator.Start() -

Relation does not exist when running Django Unit Tests

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.

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 … -
Django HTTPResponseRedirect not redirecting to the url but rather adding the integer to the url
This is my view.py file from django.http import HttpResponse, HttpResponseRedirect, HttpResponseNotFound, Http404, HttpResponsePermanentRedirect from django.urls import reverse from django.shortcuts import render articles = { 'sports': 'sports page', 'finance' : 'finance page', 'tech' : 'tech page', } def home_view(request): return HttpResponse("My App Home Page") def news_view(request, topic): try: result = articles[topic] return HttpResponse(result) except: raise Http404("404 Generic view error") def mul_view(request,num1,num2): num_result = num1 * num2 result = f"{num1} * {num2} = {num_result}" return HttpResponse(str(result)) def num_page_view(request, num_page): topic_list = list(articles.keys()) topic = topic_list[num_page] return HttpResponseRedirect(topic) and this is my url file of the app from django.urls import path from . import views urlpatterns = [ path('<int:num_page>/', views.num_page_view, name='num_page'), # path('', views.home_view, name='home'), path('<topic>/', views.news_view, name='topic-page'), path('<int:num1>/<int:num2>/', views.mul_view, name='multiply'), ] What's happening here is a bit hard to explain for me as english is not my first language but here is my best effort. I have created a function num_page_view that takes a number as a parameter and has a list of all keys of articles dictionary then the number is provided to the list as an index and stored into a variable topic that is then send as the output in the HttpResponseRedirect then i added a a new path …
