Esignature workflow implementation
I need to implement a form in my application with the frontend in flutter and the backend in django. The form needs to be signed by two people. The workflow will be as follows: User A adds their info in the form and signs it. User B adds their info in the same form and signs it. The issue is that I need the form to be in a single-page pdf but once user A signs the pdf, more information cannot be added by user B. I am using Docusign for the e-signatures. How can I implement this workflow? -

Tenant not found at 0.0.0.0 django and django-pgschemas
I am using django-pgschemas for multitenancy in my django app. Django version 3.2, python 3.10.5. I have added static tenants in this way, TENANTS = { "live": { "APPS": [ "django.contrib.auth", "django.contrib.sessions", "django.contrib.admin", 'django.contrib.messages', "app_name", ], "DOMAINS": ["live.domain.com"], "URLCONF": "app.urls", }, "public": { "APPS": [ "django.contrib.contenttypes", "django.contrib.staticfiles", "django_pgschemas", "engine", ], }, "default": { "TENANT_MODEL": "engine.Client", "DOMAIN_MODEL": "engine.Domain", "APPS": [ "django.contrib.auth", "django.contrib.sessions", "app_name_2", ], "URLCONF": "app_2.urls", } } This works perfectly with localhost. I am able to access live.localhost:8000 but when I deploy it on digitalocean using docker or apache I get the page not found error. No tenants found at http://0.0.0.0:9000. I have added the domain name in my ALLOWED_HOSTS but it doesn't seem to recognize the static tenant here. -
React component imports from a Django app package
I have created a Django project with a React front-end. I'd like to reuse some of the Django apps and their corresponding React components, so I moved them to a separate Python package following the Django docs: Advanced tutorial: How to write reusable apps. The React components are in the static folders for each Django app and are included with the Python package. The problem I'm running into is that after this new Python package is built and installed in a new Django project, to import a React component I have to import it from the Python package directory (site-packages). Is there a cleaner way to import the React components other than like this? import Comp1A from 'venv/lib/python3.10/site-packages/app_pkg/app1/static/app1/js/comp1a'; This is problematic since the location of site-packages can vary from project to project. Is there at least a dynamic way to generate this path? I can use module.exports.resolve.alias in my webpack.config.js to only set it once in the project, but I would, at least, like to be able to generate the alias automatically. -

Intro.JS possible to check user input before proceed
So, i want to come out with the Javascript which forced user to input / select anything before going to next step, (like forced user to press button, input their name, etc). I am working on Django Framework with mix together with Javascript and HTML together. Ignore the first part as I am trying to assign each function to the button so the button can do different tasks individually. But it wont work in the intro.js script.

How to use a signal to override/block a Django api request?
I've implemented a signal for my API endpoint, and I would like it to restrict access to the endpoint when the logic for the signal evaluates to false. Is there a nice way to do this? I noticed in my logs that it is properly evaluating to true or false, but it doesn't actually cause my view to send a 500 or some way of saying "access restricted". Rather, it still sends the normal API response. handlers.py from corsheaders.signals import check_request_enabled def cors_allow_mysites(sender, request, **kwargs): if ("Origin" in request.headers) and (request.headers["Origin"] == 'https://url.com'): print("Handler allowed") return True print("Handler not allowed") return False check_request_enabled.connect(cors_allow_mysites) apps.py from django.apps import AppConfig class ApiEndpointConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'api_endpoint' def ready(self): # Makes sure all signal handlers are connected from . import handlers # noqa __init.py default_app_config = "api_endpoint.apps.ApiEndpointConfig" -
Is it possible to have two different lockout reset settings for django-axes lockout?

How to maintain metrics after restart server?
I'm using Prometheus to monitor my local Django server. I successfully connected them and wrote a custom metric custom_counter in code. Unfortunately, I recognized that the custom metrics the metric custom_counter_total would always reset to 0 every time I restart my server. It sounds bad because I can only see something about it since the last time I restarted the server. Is there any method to save the metrics so we can persist the metrics even after resetting server? Thanks in advance! -
Django Cors Handler evaluating to false but not rejecting API requests
My Django Cors Framework Handler is being ran, but is not filtering anything out. When I inserted print statements to the handlers, I saw that the value was evaluating to false (meaning it had the signal to reject) but it was not actually filtering out requests to my view endpoint.

Am I missing something that will make it reject requests that don't meet the criteria in cors_allow_mysites. handlers.py from corsheaders.signals import check_request_enabled def cors_allow_mysites(sender, request, **kwargs): return ("Origin" in request.headers) and (request.headers["Origin"] == 'url.com') check_request_enabled.connect(cors_allow_mysites) apps.py from django.apps import AppConfig class ApiEndpointConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'api_endpoint' def ready(self): # Makes sure all signal handlers are connected from . import handlers # noqa __init__.py default_app_config = "api_endpoint.apps.ApiEndpointConfig"
