How at get user profile details from Django using React?
I have created an Api using django rest framework (localhost/users/profile) that gets the user's details if they are logged in.

How do I call model function in groupBy queryset inside View? Django

How can API request be "routed" through Django Backend when I want to call it from the frontend?
I am trying to make an API request to a 3rd-party server from my NextJS frontend project which requires a secret API key to be stored as an environmental variable. I used NEXT_PUBLIC_API_KEY in this case, but realized that this exposes the variable to the browser. The documentation of a 3rd-party API says " Production requests must be routed through your own backend server where your API key can be securely loaded from an environment variable or key management service." I am using Django REST as my backend; How do I "route the API through backend" when calling the API from the frontend? I see a lot of resources for node.js, but I am struggling to figure it out for Django. This is how I understood it so far, but I am not sure if it's correct and how to implement. API_KEY is stored in .env of Django server User event in frontend -> sends the data for API request to backend Backend makes the actual 3rd party API request Backend returns the API result back to frontend -

CORS issue with HTTP requests when sendign http get request to host IP
I have a development environment with python's django web server running locally. I had setup django to respond to API requests and whenever I send http GET requests to http://localhost:8000/api/service/ the server responds as expected. The issue happens whenever I send the same request using the host IP, i.e, http://192.168.15.66:8000/api/service/ (I realized the issue when trying to get the api data from another host in the LAN) I'm using postman to send the requests in order to validate whether it's working or not, though, I'm developing a javascript react application that already consumes the api data. Through the web javascript application, there's a bit more information. The browser's console presents the error message: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://192.168.15.66:8000/api/service/. (Reason: CORS request did not succeed). Status code: (null). I've been searching around and tried a few suggestions, such as: setting server/setting.py ALLOWED_HOSTS to: ['192.168.15.66'] , to [] and to ['*'] whitelisting with CORS_ORIGIN_WHITELIST to: ['192.168.15.66'] and to ['*'] Here's my setting.py MIDDLEWARE varible value: MIDDLEWARE = [ "django.middleware.security.SecurityMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "corsheaders.middleware.CorsMiddleware", "django.middleware.common.CommonMiddleware", "django.middleware.csrf.CsrfViewMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.contrib.messages.middleware.MessageMiddleware", "django.middleware.clickjacking.XFrameOptionsMiddleware", ] Any clues what I could be missing? -
How do I find all descendant models in a child/parent relationship?
Consider the following model: from django.db import models class Person(models.Model): name = models.CharField(primary_key=True, max_length=50) parent = models.ForeignKey('self', null=True, default=None, on_delete=models.SET_NULL) a = Person.objects.create(name='A') b = Person.objects.create(name='B') c = Person.objects.create(name='C', parent=a) d = Person.objects.create(name='D', parent=b) e = Person.objects.create(name='E', parent=c) Is there an easy way to find all descendants of an instance? Example of desired output: a.descendants >>> [a, c, e] -
How do I query for "greater than" on a textfield in Django?
I have a certain field in my database which is a textfield. However, for a certain use I have a set of records that only include numbers (saved as a string of course) and I want to query them using "gte" (greater than). Normally I would do: MyTable.objects.filter(text_field__gte=100) However, this does not return any results. It seems that I need to cast this field as an integer. Can I do that within this same query? The actual query is more cumbersome and involves external tables (something like MyTable.objects.filter(associated_table__other_table__text_field__gte=100)), but I am simplifying above for clarity. -
How would i go about displaying more information of objects in a ModelForm?
I've tried googling this for hours and i just can't seem to understand it. So i have a model (called Vare) that has 8 different fields with information and containes a str function. I have another model called (Rett) where you store 3 different fields and a field where you store Vare objects. I've managed to make a form for this that displayes the 3 fields + the Vare objects field, but the Vare objects field only shows the name of Vare in a dropdownbox (presumebly from the str function). Now i want to display these with more information from the 7 other fields of vare and put the into a nice looking list element instead of just a drop-down showing the name. But i can't seem to find out how you are supposed to do it. What i want is kinda like looking at amazone where you can see lots of information about the different Vare (like date crated, who is selling, price) in a nice orderly list instead of a dropdown with just the name. Currently i am just using the basic ModelForm with a meta class and i accsess it in my template as {{ rett_form.as_p }}. … -
DRF + SimpleJWT
We use DRF + SimpleJWT and we're finding that when our servers get overloaded or timed out, we're passing a 401 on the token refresh endpoint and causing users to be thrown back to the login screen (because a 401 indicates that the user is no longer authorized to view anything). Does anyone know why this might be? It only happens under really bad network conditions – we've ruled out the client and do believe it's the server returning a 401 somewhere now. When the user kills the app after being thrown back home, they are authenticated on next launch again, so it seems like we're issuing a 401 on timeout or something like that. -
How to temporatily store many user inputs somewhere in the backend within 60s?
I've been searching for solutions to this problem for weeks. My underlying struggle is that I am having trouble storing user inputs temporarily (like 60 seconds for a game. It's not like storing user IDs for each account in the backend). I want to develop a website game where it takes user input(one word as input) and counts how many words a user can give in 60 seconds. This requires the website to go back to the same website after submitting the input (but recorded each user input in the backend and count on it). I guess that I should use session in django but I'm still not sure about how should I approach this problem. -
How to Aggregate By with django-tables2 and keep linkify?
With django-tables2, I found I can either have an aggregate by querying model.objects.values('foo_bar').annotate(...) but only the values themselves are passed. If I try to linkify a column, I get an error that for linkify=True, 'FOOCOLUMN' must have a method get_absolute_url. If I pass model.objects.all(), I can linkify columns, however, it seems that you cannot aggregate. Is there a way to aggregate/annotate in django-tables2 while keeping linkify? -
Serving Vue.js static files and Django app running on gunicorn over Nginx
I have a web backend implemented in Django and running on Gunicorn. Plus, I also have a Vue.js app that uses this backend. I want to run both of them on nginx and also do HTTPS configs.

How do i make a list from Django queryset and format the annotate field?
