expanding dict model field in django
I need a way to be able to enter an unspecified number of arbitrary, integer values with an auto-incrementing key into a dictionary in a django model. It would need to look, or at least function, like this: { "1":6, "2":10, "3":0, ... "n":42 } I'm hoping there will be a simple solution like: class Foo(models.Model): title = models.CharField(max_length=100) dictOfInts = { models.AutoField(): models.IntegerField, models.AutoField(): models.IntegerField, models.AutoField(): models.IntegerField ... # it would start with just one and automatically add more k-v pairs as nessary } #other fields ect def __str__(self): return self.title Unfortunately, I know that doesn't work and wouldn't function how the comment suggests, but it would need to act like that for the end-user. I've looked through the docs and the only workaround I found there was using models.JSONField(), but that requires you to type out the dict yourself, which is not ideal. Another possible way that I found would be to separate the dict and the k-v pairs, linking them with a foreign key, but I couldn't quite figure out how to integrate it and it seemed very messy even if I could. If you need any more info, just let me know. Any help is much … -
Unable to push json file to Heroku for database data dump
I'm working on a school project, I have no experience with any of this and am having a hard time with this last step of setting up a website. For some background, the front end is coded in Next.js, backend is Python utilizing Django, and I have deployed the backend to Heroku (I have the app built and the database (postgreSQL) setup). I have done all of this following a tutorial that I found on Udemy which is only about a year old. I have run into some issues along the way but was able to figure them out after some trial and error, but this one is really giving me a hard time. So, in the tutorial he does a datadump and puts it into a file named "dump.json", then he runs the following command: heroku run python manage.py loaddata dump.json, which dumps the data into Heroku and the database populates and his Heroku app is up and running (it's connected to the Django rest framework, which is coded in the front end). Well, here is what I get when I run the command, I have to specify the path to manage.py otherwise it won't work, fyi... I have … -
django "no such table" when adding database entries via terminal
I am trying to create a relational database (one to many) in my models.py file. But when trying to add entries into my database i get an error saying: django.db.utils.OperationalError: no such table: app1_prices.

Increasing the searching speed of Django set.all()
I am using Django to filter through a MongoDB full of data. Right now I have code that is working and have found where my slowdown is at... def does_this_property_apply(prop, app, dev, event): for platform_device in prop.platformdevice_set.all(): for event in platform_device.applicable_events.all(): if event.name == event: for app in platform_device.applicable_app.all(): if app.name == app: for device in platform_device.applicable_device.all(): if device.name == dev: print("This property applies") Basically I have 400+ properties that have a bunch of metadata. Inside of each property is a platform_device object (model) that contains information such as app, dev, and event. Think of it as this property only applies to certain applications, on certain devices, on certain user actions (events). Each property can have multiple of these. I am new to Django and trying to find out how I could quickly search all platform_device in the database and find if this property (prop) is applicable to my event, device, and application. class PlatformDevice(models.Model): _id = models.UUIDField(unique=True, primary_key=True,default=uuid.uuid4, editable=False) name = 'Property Specifics' property_field = models.ForeignKey('Property', on_delete=models.CASCADE) applicable_app = models.ArrayReferenceField(to=Platform, on_delete=models.CASCADE, blank=True) applicable_device = models.ArrayReferenceField(to=Device, on_delete=models.CASCADE, blank=True) applicable_events = models.ArrayReferenceField(to=Event, on_delete=models.CASCADE, blank=True) event_group = models.ArrayReferenceField(to=EventGroups, on_delete=models.CASCADE, blank=True) def __str__(self): return self.name -

Showing data on frontend from sql databases using django
For fetching data from databases, I usually see people create a class in models.py and they migrate it, and then they fetch data from databases and show it on the front-end. my question is, i already have a database which has student_info table and has lots of data. I don't want to define student_info class in models.py and do migration. Instead, since i already have student_info data in sql database. so I want to fetch it directly. can i do so? one method i know of doing the same, is directly connecting sql server in views.py as; mydb=mysql.connector.connect(host="localhost",user="root",password="******",database=database_name) and fetching the data and passing it as variable in index.html. But the problem is, it fetches data only once, and if i refresh the page where local server is running, all the content will disappear, and server will report Broken pipe from ('127.0.0.1', 59579) and to see the data, again i need to restart the sever. Kindly looking for a better approach to show data on front-end from the existing databases -

Django/Vue -> Heroku: Static files not loading at production server
Static files load when DEBUG=True (locally and at the dev server), but not when DEBUG=False (production). STATICFILES_DIRS is set to my dist dir created by Vue, and dist is not in the .gitignore. Heroku runs collectstatic on every deploy by default (I have not changed this). The actual error is a 404 when trying to load any static file. The whitenoise package is being used. I've updated the middleware settings, and wsgi.py according to the docs, and have the settings variable which enables compression via whitenoise set (also according to the whitenoise docs). whitenoise usually works fine with other apps. I'm not sure what's wrong with this. The difference is that I'm using Vue for the first time. I'd never used a js framework before. Can anyone help? -
