Django-React app search bar implementation
I want to implement a search bar on one of my pages in the Django-React app. I am a complete newbie in React and I am struggling with achieving the desired results.

Javascript is not working properly inside djagno project

More specifically, the document object does not have a body, but only the head of my html. Thus I am not able to access its classes.

Django: Use a read-only database within django test suite
In my Django project, I'm using two databases, one of which is my own PostgreSQL database where I have the read and write rights, and the other one is an external PostgreSQL database in which I only have read-only rights. It works perfectly in the context of the project, I can access both databases. However when I use the Django test suite using ./manage.py test, Django is trying to create a test database for the external database. I don't want that, I want to be still able to access the external PostgreSQL database within the test suite without needing to create a test database on this external PostgreSQL database. It also gives me this error: /usr/local/lib/python3.10/site-packages/django/db/backends/postgresql/base.py:323: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the first PostgreSQL database instead. But I don't have access to the 'postgres' database in the external database and I don't want to run initialization queries against it. Here is the configuration for the external read-only database connection: DATABASES["aact"] = { … -
Accepting JSON format, parsing him and having endpoints to accessing the data (Django)
Hello I want to ask how can I create models and API in Django that accepts JSON format, parsing it and then access it in some of the endpoints. I need to have [POST] endpoint /import which will accept the data and parse them, [GET] /detail/<name_of_the_model> will show list of records from the JSON file based on the name of the model and finally /detail/<name_of_the_model>/<id> which shows all the data for the exact record from the JSON file.

Gunicorn (Django + NGINX) keeps date till Gunicorn restart
I'm moving Django apps from Apache2 to Nginx/Gunicorn and have one problem. I used simple tutorial from Digital Ocean to setup Nginx/Gunicorn environment apps and all is steady, working fine. But i found out i have some strange problem with date. It looks like all my apps run the same day, the day app was started/restarted. Queries to DB for yesterday items return 0 rows. When i reset gunicorn or run the app via ./manage.py runserver all works as expected. Same code using old server (running Apache2) works fine too. So there is no problem with the code, but config issue. Somehing like Gunicorn freezes in time(date) and needs to be regularly restarted? Or I'm missing something in my settings? My socket file: [Unit] Description=VKCRM [Socket] ListenStream=/run/vkcrm.sock [Install] WantedBy=sockets.target my service file: [Unit] Description=VKCRM daemon Requires=vkcrm.socket After=network.target [Service] User=www-data Group=www-data WorkingDirectory=/var/www/virtuals/crm/vkcrm ExecStart=/var/www/virtuals/crm/bin/gunicorn --access-logfile - --workers 1 --timeout 100 --bind unix:/run/vkcrm.sock vkcrm.wsgi:application [Install] WantedBy=multi-user.target Thanks for any help, it must be some basic settings stuff. Maybe restart Gunicorn each day, restart workers after jobs done or something like this? But can't find out what i'm missing. -

How to pass arbitrary Python object (e.g. InMemoryUploadFile) to a different Django view
This question will likely betray my inexperience in web development, so please let me know if I'm solving entirely the wrong problem. I'm building a web application where users are asked to upload a data file. After uploading, the users are shown some aggregate statistics of the data contained in the file to help catch any errors. The user can then confirm this is the right data. Only then will the file will be stored somewhere on other people's computers in the cloud. I Django, I have defined three views/templates: Upload: the template contains the form that allows the user to select a file to upload.
