CSRF verification failed behind Route 53
I have a dockerized Django app that utilizes Gunicorn and Nginx. When logging in on the admin page using localhost, no CSRF error emerges. When running the docker on Amazon EC2 with Route 53 as the proxy server (https redirects to http), I get the CSRF error on login. I note the following in my settings.py file (I added the SECURE_SSL_REDIRECT = False but it has had no effect): ALLOWED_HOSTS = ['localhost', '.website_name.ca'] SECURE_SSL_REDIRECT = False # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'The6ixDjango.apps.The6IxdjangoConfig', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] Given that I have Route 53 on the front-end, is it 'safe' to remove the csrf middleware reference in the MIDDLEWARE list? -

Django: Could not find the GDAL library (OSX)
After my old macbook died I am transferring across a Django Webapp I'd been building to my new machine. I am currently in the process of reinstalling the correct packages and extensions for the app. However I am currently getting the following error when I do python3 manage.py runserver: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal", "GDAL", "gdal3.3.0", "gdal3.2.0", "gdal3.1.0", "gdal3.0.0", "gdal2.4.0", "gdal2.3.0", "gdal2.2.0", "gdal2.1.0", "gdal2.0.0"). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings. The database I created was through a server on Postgres.app which I believe comes packaged up with PostGIS, GDAL etc. I have tried following the geoDjango documentation and I added the following in the terminal: export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/14/bin When I run which psql it returns: /opt/homebrew/bin/psql Is this a conflict between a homebrew and Postgres.app installation or something?

Instantiating dependencies (e.g. service clients) in Django
A Django API view calls another service. To call that service, the view needs a client. I'd like to initialize globally an instance of the client and pass that instance to the view. Also, for tests, I'd like to be able to easily mock the client. I can do some terrible hacks (hey, with Python everything is possible!) but I'd like to do it in Django-idiomatic way. I tried as_view(**initkwargs) and passing the instance of the client. The drawback is that in tests I need to modify class variable (and not instance variable, which seems more correct), and also I need to instantiate the client in urls.py which doesn't look like a right place to instantiate such clients (dependencies). I considered having a separate Application in INSTALLED_APPS, but it seems like an overuse of what an Application should do. In my case, the App would only run AppConfig.ready() and would initialize the client for later access by a view. A simple Dependency Injection would do, but I don't want to overcomplicate that, if Django supports equivalent functionality. Where should I initialize such dependencies in Django, and how to later mock them in tests? -

Django (REST Framework) - How to add fields to queryset iteration
I need some advice for making a query in Django (DRF). I'm trying to make a queryset for Products, where every Product gets a field "images" with all the Images for that product (coupled using ProductImage model), but I can't figure out how to add the field. Below is my ProductViewSet class ProductViewSet(viewsets.ModelViewSet): serializer_class = ProductSerializer queryset = Product.objects.all() def get_queryset(self): queryset = Product.objects.all() product_list = [] # iterate over all products for product in queryset: # find Image ids for product image_ids = list(ProductImage.objects.filter(product=product.id).values_list('image', flat=True)) images = [] # iterate over images and add to images list for image_id in image_ids: image = list(File.objects.filter(id=image_id).all()) images.append(image) # add images field to product # product['images'] = images # "TypeError: 'Product' object does not support item assignment" product.images = images # Doesn't do anything. # add product to product list product_list.append(product) return product_list I've tried to do the following to add the field "images": product['images'] = images which gives the error "TypeError: 'Product' object does not support item assignment" product.images = images which doesn't do anything... Could anyone point me in the right direction? Any tips on how to make this query in a better way are also welcome! -

How to serve MEDIA uploads from summernote in prod hosting?
Good afternoon and Happy New Year! In the admin panel, when creating a post, the uploaded images are not displayed. Neither in the admin area nor in the published post. They are in the folder with the downloaded images, and through the Django admin panel, a link is visible (but it does not open, "Not Found The requested resource was not found on this server") and they are uploaded to the hosting (they appear in the django-summernote folder by dates). Tell me how to fix the situation? The statics loaded normally, everything is displayed OK. The only problem is with those files that the user uploads when the post is compiled. .htaccess at the slightest change from the standard one provided by the hoster - the site stops opening. From this and the working statics, I assume that Apache is configured normally, especially since the hoster's infrastructure does not contain a mention or a requirement to change it. Thanks!

I'm hosting my media-files from the same server as I host my Django application in. From time to time I need to add some more files for being served from the application, such as images. I have set up so NGINX serves all my media files in a directory called /mediafiles inside my docker container, this is the same place where all images that a user upload will be located. What I want to do is to add some files into my repo, and copy these files over to /mediafiles in the container, and be able to reach them trough the application (when run locally) or NGINX (when run in my server). However, I'm running into some problems. I've tried with the following line in my Dockerfile: COPY ./reponame/mediafiles $APP_HOME/mediafiles Which works, but ONLY after I've run: docker system prune --volumes Which isn't something I can do on the server, because this is where all the users uploaded images will be located. I know that this isn't the optimal set-up as you should use an external file storage for user-media, but this is what I can spend on my project at this time and haven't found a good storage solution … -
How to access attributes of 'child' model in Django?
models.py class Post(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, name="post_id") postauthor = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='postuser') class PostImage(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, default=None,) image = models.ImageField(upload_to=user_directory_path) Before I write too much and describe everything I have tried so far, what would be the best way of showing all images for every post in a single view? Let's say I would use the images as thumbnails for the posts. Thank you. -
How to sum time based on a given time in django?
class Clock(models.Model): report_submitted_at = models.TimeField() delivery_time = models.TimeField(null=True, Blank=True) I am new to Django so I am curious how to achieve this. In my model report_submitted_at time I am entering. Based on the entered time i want to save the delivery time automatically. Delivery time is always '04:00:00'. So suppose i entered report_submitted_time '02:00:00'. The delivery time will be '06:00:00' for that row. I imported datetime. Manually i am able to add two times. But here how can i save the delivery time automatically. Any help would be really appreciated. Thank you !! -
