Django Ninja REST API to React - Forbidden (CSRF cookie not set.)
I made a Django REST API using Ninja API, and most calls work, except POST, DELETE, etc.. CONFIGURATIONS Django site URL: http://127.0.0.1:8000/ API CALL: http://127.0.0.1:8000/hello Methode: POST Parameters: None settings.py: INSTALLED_APPS: [..., "corsheaders"...] MIDDLEWARE: [..., "corsheaders.middleware.CorsMiddleware"...] # Set CORS settings CORS_ALLOW_ALL_ORIGINS = True CORS_ORIGIN_ALLOW_ALL = True CSRF_HEADER_NAME = "HTTP_X_CSRFTOKEN" CORS_ALLOWED_ORIGINS = [ "http://localhost:3000", ] CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_NAME = "X-CSRFToken" CSRF_HEADER_NAME = "X-CSRFToken" CSRF_TRUSTED_ORIGINS = [ "http://localhost:3000", ] generate csrf token for react GET: @router.get("/get_csrf_token", summary="Get CSRF Token") def get_csrf_token(request: HttpRequest) -> JsonResponse: """.""" csrf_token = get_token(request) print("TOKEN: ", csrf_token) return JsonResponse({"csrf_token": csrf_token}) hello POST rest api call: @api.post("/hello") def hello(request: HttpRequest, data: HelloSchema) -> str: """.""" return f"Hello {data.name}" React site When I make a call to django I get a csrf_token: const tokenResponse = await axios.get("/login/get_csrf_token"); const csrfToken = tokenResponse.data?.csrf_token; which is used in my REST API /hello call: const response = await axios.post("/hello", { headers: { "Content-Type": "application/json", "X-CSRFToken": csrfToken, }, credentials: "include", }); PROBLEM First, I fetch the CSRF token from my Django REST API and use this CSRF token in my HEADER for the POST calls, but I get a forbidden 403 every time.

Bootstrap modal not sending a request to django view for rendering model form
I'm currently working on a django project that manages inventory of biological samples. I have a specimen details page that renders four tables with data associated with the selected specimen. In each of these tables I have an Edit button where the user can update a record associated with the specimen. Right now, when the button is clicked, a new page is opened and the update form is rendered. I'd like to use a bootstrap modal to create a popup of the form instead of having to go to a whole new page. I already created something similar on the home page for adding a new specimen record and it works great. For some reason tryin the same thing on the details page will not work. The modal does pop up, but the form does not render and it seems like the issue is that there is no request being sent to the edit_specimen url/view even though it is specified. Im wondering if it has to do with urls and the pk being in the url for this operation. I've tried several things and I can't get it to work. Any advice is appreciated as I am relatively new to … -

Check if Django is able to connect with given parameters or return an error message, instead of causing an internal server error (500)

Now I get, for example: Exception Type: OperationalError Exception Value: (1045, "Access denied for user 'test'@'localhost' (using password: YES)") In those case I would just … -
celery beat ExpressionDescriptor.py get_full_description
I hope your day is going well. I've hit a bit of a snag with a Django project I’m working on. I'm relatively new to Django and would deeply appreciate it if you could spare a moment to help me troubleshoot an issue. I'm using Celery Beat for scheduling periodic tasks. I have a view in the admin where I check and set periodic tasks, but recently a strange error has appeared, and I can't locate the issue. Whenever I try to open any admin view with periodic tasks, I get this type of error: It indicates a problem with resolving the names of the crontabs: During handling of the above exception (invalid literal for int() with base 10: '0DAY'), another exception occurred: But I haven't changed anything in the database or modified anything with settings. Do you know how I can resolve this issue, or where to look for a solution? It's probably a default setup and nothing there is set or modified, and I also couldn't find any solution to my problem on the internet :( I'm using : django-celery-beat==2.5.0 Django==4.2.2 I do not have any external settings to celery beat in django project :( -
Password change form URL in Django admin cannot find user with correct ID
I'm having some trouble with my admin settings. I am using a custom user model (called Org, for context), and everything works perfectly in the admin except for the password change form. For clarity, I'm talking about the little form that says "Raw passwords are not stored, so there is no way to see this user’s password, but you can change the password using this form." However, when I click on "this form", I'm redirected back to the admin homepage, with the warning "Org with ID '40/password (40 being the ID)' doesn’t exist. Perhaps it was deleted?" Examples of inline and admin # all inlines look like this: class OrgContactInfoInline(admin.TabularInline): model = OrgContactInfo @admin.register(Org) class OrgAdmin(admin.ModelAdmin): inlines = [OrgContactInfoInline, OrgInfoInline, OrgLocationInline, ItemInline] add_form = CustomUserCreationForm form = CustomUserChangeForm model = Org ordering = ("-org_name",)``` Important forms class CustomUserCreationForm(UserCreationForm): password = forms.CharField( widget=forms.PasswordInput(), label=mark_safe( "Your password must:<br />-Be longer than 8 characters<br />-Have an uppercase and lowercase characters<br />-Use a special character/number" ), ) confirm_password = forms.CharField(widget=forms.PasswordInput()) class Meta: model = Org fields = ["org_name"] class CustomUserChangeForm(UserChangeForm): class Meta: model = Org fields = ["org_name"] URLs urlpatterns = [ #my urls path('', include('apps.homepage.urls')), path('accounts/', include('apps.accounts.urls')), path('mynonprofit/', include('apps.dashboard.urls')), #django urls path('accounts/', include('django.contrib.auth.urls')), … -
How to syncronize the elimination of two components
Lets say I have two componentes that display a common component when I make a delete request to the api inside one of the componentes the other component does not get deleted until I refresh the browser how can I fix that such that the common component gets eliminated at the same time here are the components: import React, { useEffect, useState } from "react"; import { getTasks } from "../api/task.api"; import { TaskCard } from "./TaskCard"; export function TaskLists() { const [tasks, setTasks] = useState([]); useEffect(() => { async function loadTasks() { const res = await getTasks(); console.log(res.data); setTasks(res.data); } loadTasks(); }, []); const removeTask = (id) => { setTasks(tasks.filter((task) => task.id !== id)); }; return ( <div> {tasks.map((task) => ( <TaskCard key={task.id} task={task} onDelete={removeTask} /> ))} </div> ); } and import React, { useEffect, useState } from "react"; import { useNavigate } from "react-router-dom"; import { getTasks } from "../api/task.api"; import { TaskCard } from "./TaskCard"; export function Daycard({ hashv }) { let b = 0; const [tasks, setTasks] = useState([]); useEffect(() => { async function loadTasks() { const res = await getTasks(); console.log(res.data); setTasks(res.data); } loadTasks(); }, []); const removeTask = (id) => { setTasks(tasks.filter((task) => task.id … -

calling a view without passing request
I have a view that is called like this. def device_check(request, d, i): # A bunch of stuff the view does When i call this view by default it works perfect no issues, then i have another function that generates some data and tries to call that function to check and i keep getting the error that its not passing enough arguments, since i am trying to use it like this def test_function(request): test = device_check("test", "i-1799") And i understand the error is being caused because i am not passing it the request parameter like so device_check(request, "test", "i-1799") But i have no idea how i would pass it the request parameter from within another function. Is there a better way of doing this, or a way around that? -
Cannot Grab request.get_host() from Django Request to get real domain name
I use docker and nginx to run my system but I am hitting an issue now to where I would like to redirect client users of my system automatically to a subdomain. i.e. something like prod.example.com. This already works in my nginx config to duplicate access to the page, but I would like to map specific client urls to the subdomain, not the main one. Normally this would be simple in Django using something like: if not 'app.' in request.get_host(): redirect(f'app.{request.get_host()}') # example # get_host()=app | get_absolute_ur()=http://app/, meta: app But my nginx proxy pass uses an upstream variable, and it appears that is all that is posted through with the variables tried above. How can I get this done? upstream app { server web:8000; # appserver_ip:ws_port } server { server_name prod.example.com; listen 80; client_max_body_size 250M; # enforces HSTS or only content from https can be served. We do this in CloudFlare add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always; add_header Permissions-Policy "autoplay=(), encrypted-media=(), fullscreen=(), geolocation=(), microphone=(), browsing-topics=(), midi=()" always; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://app; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_headers_hash_max_size 512; proxy_headers_hash_bucket_size 128; } }
