How to require non-admin login before accessing Wagtail admin login
I am working on a Django App that uses Wagtail and django-allauth. I am using a workaround from Allauth docs to take advantage of some Allauth's features which are lacking in vanilla Django Admin login. from django.contrib import admin from django.contrib.auth.decorators import login_required admin.site.login = login_required(admin.site.login) I am trying to do the same for the Wagtail Admin, but am having no luck so far. My difficulty might be because the Wagtail admin views are class-based - I don't think I can use method_decorator in this context. Any help or pointers are highly appreciated. -
How to adjust ChainedManyToManyField to populated field based on another field?

Test Django validator with parameters
I want to test a custom validator for an ImageField that checks that the aspect ratio of the image is between the given parameters. The validator takes a min_aspect_ratio and a max_aspect_ratio parameter, and returns a validator function, which takes the image from the ImageField: def validate_image_aspect_ratio(min_aspect_ratio: int, max_aspect_ratio: int): """Checks that the proportions of an image (width / height) are what we expect.""" def validator(image): if image is None: return aspect_ratio = image.width / image.height error_message = _( 'Image\'s height proportion to its width should be between %(min_aspect_ratio)s and %(max_aspect_ratio)s.

What is a good way to proceed to store and use sensitive data in prod environment?
I have a django web app in a production environment hosted on a server. To store sensitive data I am using a .env file excluded from my git process stored on the server where my app is hosted. # .env file { "ENV_TYPE": "prod", "SECRET_KEY": "mysecretkey", "ALLOWED_HOSTS":[ "somewhere.com" ], "DEBUG": false, "STATIC_ROOT": "/somewhere/staticfiles", "DATABASES": { "default": { "ENGINE": "django.db.backends.mysql", "NAME": "databaseName", "USER": "username", "PASSWORD": "myPassword", "HOST": "somewhereelse.com" } } } And in my app I get back data like this in setting.py for instance: # setting.py # Get back non secret env data such as DEBUG, ALLOWED HOSTS with open(os.path.join(BASE_DIR, '.env'), 'r') as f: env_data = json.load(f) # SECURITY WARNING: keep the secret key used in production secret! SECRET_KEY = env_data["SECRET_KEY"] # SECURITY WARNING: don't run with debug turned on in production! DEBUG = env_data["DEBUG"] ALLOWED_HOSTS = env_data["ALLOWED_HOSTS"] Do you believe this is a good way to proceed ? Indeed I still have somewhere on my server some passwords that are hard coded. -
Apache24 Production Server For Django React App: React Shows 403 Forbidden Error
I am trying to run a production server on an AWS EC2 instance (Windows) using Apache for a Django backend connected with a React frontend. When I test the app on Django's runserver everything works well, but currently, when I try to use it on Apache I am just seeing a blank screen. When I check the console it tells me that I don't have permission to access the react static files (403 forbidden error). In my attempts to fix this, I have run collectstatic, which has put all of the static files (including the react ones) on an S3 Bucket. This means that the Django pages (admin pages) are able to use the static files, but the React pages aren't accessing the files from the S3 bucket. I'm not sure if it is better to find a way to get my React app to use the static files from the bucket, or if I should just continue to find a way to get Apache to serve the static files. I know that the files are able to be found because it isn't a 404, but a 403, so it must be some problem with my configuration that isn't giving … -

How to make the django rest framework POST button work?

In the Django Rest Framework in /api/ads/ I can see all my previous ads created using the django admin and below a form to post data which looks like this: When I click on the POST button of the form,it doesn't make a POST request it just reload the page. I can confirm it from the Firefox devtool and the server log, no POST request are made. So my question is this: how to make this POST button works as expected so I can check my serialiser and everything work as it should ? -

Can I modify the URLs Django uses for "View on site" admin links to override caching?
My site is behind a cache. I use Django's "View on site" functionality (eg. by defining a get_absolute_url method for each model), but when I make a change to an object and then click "View on site", I don't see the changes because the cache hasn't expired. I don't particularly want to do things like check the referrer header (eg. Django admin routes these URLs via a redirect like /admin/r/19/1653/, which I could test for) as this breaks my cache strategy (I don't currently cache based on referrer). I tried injecting a timestamp query parameter via JavaScript (eg. to send admin users to /some-django-url?ts=12345, which would bust the cache) but this doesn't work because of the above redirect step (eg. I can't "see" the final Django URL in the admin screen, just the /admin/r/ redirect). Does anyone have a good strategy for this?
