access a Url with a query inside a modal
I want to open the content of a page inside a modal, but this page is accessed by a query string like: add_data?filter=crew So, my modal needs to access the page, but I can't include a url, just a html page: <button id="myBtn">+ Add</button> <div id="myModal" class="modal"> <div class="modal-content"> <span class="close">&times;</span> {% block survey_index %} {% include 'add_data?filter=crew' %} #It doesn't work {% end block %} </div> </div> This way doesn't work since the include expects me to pass a html page like: {% block sample_unit_type_index %} {% include 'inv/index/example.html' %} {% endblock %} How to access the page that is in add_data?filter=crew url code: path('add_data', add_data, name="add_data"), views.py return return render(request, 'inv/add_new.html', context) So the page add_new.html has the content accessed by the queries. Example: <a href="add_dados?filter={{path_info}}" class="btn3 add" role="button">Add</a> Any suggests to access the add_data?filter=crew page content in modal? -

Can programmatically upload objects to S3 bucket but GET request is forbidden
I'm writing a django app which needs file uploads. I've created an S3 bucket and an IAM user with S3FullAccess permissions. I took the access key ID and the secret access key and put them in my code (using env variables). I'm using django_storages to send uploaded files to S3, and my config in my settings file is AWS_ACCESS_KEY_ID = os.environ.get('S3_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('S3_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = '<my bucket name>' AWS_S3_REGION_NAME = 'ap-south-1' AWS_S3_SIGNATURE_VERSION = 's3v4' AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' The CORS policy for the bucket for now is [ { "AllowedHeaders": [ "*" ], "AllowedMethods": [ "GET", "PUT", "POST", "DELETE" ], "AllowedOrigins": [ "*" ], "ExposeHeaders": [] } ] Using this configuration, I'm able to upload files to the S3 bucket from my application, but when that file is requested by the application, I get a 403 Forbidden error. How can I fix this? -

django-tenants: Newly created app’s migrations are reflecting as expected in public schema of the database, but not in tenant-specific schemas
We had authored two applications since the beginning the project* The same has been part of the multi-tenancy architecture in a single database, semi-isolated fashion using a multi-schema approach. We have built a third application that we also want to integrate into django-tenant schemas that’s failing to reflect their tables in the database, in tenant-generated schemas. However, the migrations for the newly created app is successfully migrating and creating tables in the public schema. The same is failing to reflect in tenant-generated schemas. This is happening for any new app that is created through Django. We are using PostGIS as original backend and django-tenants as database engine. Current Django version=3.2.12 Current PostgreSQL version=12 Current django-tenants=3.4.1 -

Popup With JavaScript not working with Django template
The follow code is not running in a Django project. Is there any limitation when using popups in django? In this case, the white window does not open with the text.

Docker-Compose Init Postgres Failing
I've been attempting to make a docker-compose file work, and so far it's been closer and closer, but not quite there. Maybe asking the questions will be useful to someone else in the future. Anyway, the previous thread was here: Docker-Compose Postgresql Init Entrypoint From which I learned, between runs a docker-compose file should have docker compose volumes --down and if the POSTGRES_DATABASE isn't specified, then the POSTGRES_NAME will replicate to the POSTGRES_DATABASE. another suggestion from Discord has been to rewrite some of the volume signature to include the file path to init.sql as in docker-entrypoint-initdb.d/init.sql So if I docker-compose down --volume and then sudo docker-compose build && docker-compose up with version: "3.9" services: db: restart: always image: postgres volumes: # - ./data/db:/var/lib/postgresql/data - ./init.sql:/docker-entrypoint-initdb.d/init.db environment: - POSTGRES_NAME=dev-postgres - POSTGRES_USER=pixel - POSTGRES_DATABASE=lightchan - POSTGRES_PASSWORD=stardust web: build: . restart: always command: sh -c "./waitfor.sh db:5432 -- python3 manage.py runserver" volumes: - .:/code ports: - "8001:8001" environment: - POSTGRES_NAME=dev-postgres - POSTGRES_USER=pixel - POSTGRES_DATABASE=lightchan - POSTGRES_PASSWORD=stardust depends_on: - db Then the following is output: Attaching to lightchan-db-1, lightchan-web-1 lightchan-db-1 | The files belonging to this database system will be owned by user "postgres". lightchan-db-1 | This user must also own the server process. … -

Django object update using htmx and SingleObjectMixin

How test the presence of CSRF in an APIView (DRF)?
I have an API, with JSON as content-type, built with Django Rest Framework. There is an endpoint which permit login the users, for that I am using simple-jwt package, and how the view has permission_classes = [AllowAny] and works through POST method to make the login, so I added the CSRF token to this view: @method_decorator(csrf_protect, name='post') class TokenCookieObtainPairView(TokenObtainPairView): ... When the header and cookie that have the CSRF doesn't match, a template of django (views.csrf.csrf_failure) return a 403 status, but I overrided that (method finalize_response()) to return a message to the consumer. if response.status_code == status.HTTP_403_FORBIDDEN: serializer = MessageSerializer({'message': self.MESSAGE}) new_response = Response(serializer.data, status=status.HTTP_403_FORBIDDEN) return super().finalize_response(request, new_response, *args, **kwargs) I created a test for that view.

Widgets and static files
I'm trying to use a custom widget for plus and minus buttons and I struggle to link the widget to its css and js files. So in my app I got this form : class MyForm(forms.Form): degree = forms.DecimalField(label="Degree", max_digits=3, decimal_places=1, required=True, widget=PlusMinusNumberInput()) Calling this widget : class PlusMinusNumberInput(Widget): template_name = 'widgets/plus-minus-input.html' class Media: css = { 'all': ('css/plus-minus-input.css',) } js = ('js/plus-minus-input.js',) I got a "static" directory at the root, with my files in css and js folders. The static parts of my settings are as follow : STATIC_URL = '/static/' STATICFILES_DIRS = [Path.joinpath(BASE_DIR, 'static'),] STATIC_ROOT = Path.joinpath(BASE_DIR, 'staticfiles') At the end the html file render well but not the js and css. Do you know why ? -

So I want to be able to: 1) get the difference of the check in and check out dates in the front-end 2) then compute the total cost in the frontend 3) then make stripe (django backend) know about this total cost and charge accordingly I need help with (3).
