django form queryset getting user data and filtering by team
I have a User-Team model setup. When a user creates a "project" they can assign the project to people on their team. However, when I use a queryset in my multiple select form field, it of course shows all users in the entire database. How can I filter just on the user's team?

Django: Button feeds from database entries
I'm trying to solve a problem that i don't find on google ( apparently ). I got a Django Project which allows People to get registered. I got my form which is something like this: forms.py class RegistrationForm(UserCreationForm): """docstring for RegistrationForm""" email = forms.EmailField(required=True) studio_associato = forms.CharField(required=True) nome = forms.CharField(required=True) cognome = forms.CharField(required=True) class Meta: # define a metadata related to this class model = User fields = ( 'username', 'nome', 'cognome', 'studio_associato', 'password1', 'password2' ) I managed to correctly store and visualize the User in the DB and the admin page. What i'm trying to get is to let this field 'studio_associato' be a field that when a User register himself through the registration form, he have to specify from which (in Italian Studio = Office ) Office he's working for. Each User can only work with an Office unlike Office could have obviously more Users linked to it. My final product i'm trying to achieve is a field: "Studio associato" (showed during the registration form of the User) which displays all the Offices registered till that moment and let you Click or Search a specific Office to link that user for.

What would be the best option to host a personal website? [closed]
I would like to find the best solution to rent a server to host a personal website running Django. It'd be better if it runs on Linux and other than that, the only thing as I said is that it will be a Django website. Traffic should be low as it will only host showcase projects, as in other CV-looking websites you may have encountered. I know nothing about server/hosting services, but I know how to host on a home server though. I looked in AWS but man... Too many offers, pricing is really shady. I can be down with it but for now I don't really understand. Some of you must have dealt with this situation, I'd like to have your opinion. What would be my best option ? -

Prepopulating a Django model with large amounts of data
I'm trying to load a list of Rolling Stone's top 500 songs - as well as other characteristics such as their rank, description, cover image, ect. - into a Django database so that I can display a random song each day on m. I managed to scrape the list from the site well enough, but I'm having trouble loading the list into the database as a single instance of the model I created, as opposed to 500. I tried writing a migration to do it for me, but I don't think it worked properly. I've attached the code below, let me know if you see anything: # Create function to actally load data into table def loadSongs(apps, schema_editor): # Initialize counter to iterate through site pages, initialize album rankings, create model, then scrape pages one by one #top500songs = Songs() links = np.arange(1,11,1) rank = 500 songList = [] for link in links: # Get and store link to page, initialize lists to store data values page = requests.get('https://www.rollingstone.com/music/music-lists/500-greatest-songs-of-all-time-151127/?list_page=' + str(link)) soup = BeautifulSoup(page.text, "html.parser") # Look for song entries on the page, stored as articles with "item" class.

How to add a new view to django-oscar

Secure data PUT from IoT devices to DRF backend
I have not been able to find any helpful material on this subject. I am looking for a primer on how to restrict certain endpoints in DRF to accept data from only certain 'whitelisted' IP address. I am aware of adding the IPs to 'REMOTE_ADDR' settings but that doesn't fully solve my problem. Users will have IoT devices with static IPs. Data streaming from these devices need to be added to the db in a secure manner with the User/tenant specific information along with it. I am thinking IP restriction might be the best way of going about it. Please let me know if there are other better ways. Frameworks used: DRF django_tenants Postgresql -

Is it a good practice to store SQL query in the database?
My Usecase: We allow the users of the system to create a list(i.e segment) of contact details based on the variety of the filters from the UI. So they create the segment using a form to select say all people living in a particular state. So the issue here is that, when the new contacts are added, I want these segments to be updated as well. The solution that I can think of is saving SQL query for each segment and update each segment when new contacts are added using these SQL queries. I thought of saving only parameters in a json string format but complication in that case is filters available are over multiple tables and there is no way to generate the dynamic SQL query as it invovles joins and different filters (i.e. 'in', 'endswith', etc). I don't think either of them is the best solution. Any better ideas? Any help would be appreciated, thanks in advance! -
