Django server 403 (CSRF token missing or incorrect)
I have a basic Django server with an python command line client for posting to this service. I have a login function and a post function. Even though the cookie for CSRF is being set from the login function the server is saying forbidden when I try to access the post_product endpoint after logging in. I've been troubleshooting this for days and haven't had any luck. /api/login/ function: from django.views.decorators.csrf import csrf_exempt from django.contrib.auth import authenticate, login, logout from django.http import HttpResponse @csrf_exempt def handle_login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username=username, password=password) if user is not None: if user.is_active: login(request, user) if user.is_authenticated: return HttpResponse(author.name + ' is logged in, Welcome!', status=201, content_type='text/plain') return HttpResponse(data) else: return HttpResponse('disabled account', status=400, content_type='text/plain') else: return HttpResponse('invalid login', status=400, content_type='text/plain') else: return HttpResponse('request method invalid ' + request.method, status=400, content_type='text/plain') /api/postproduct/ function: def post_story(request): if request.method == 'POST' and request.user.is_authenticated: # Pull product details from request. # Validate product details. # Create model and save.

Image upload to the rich text field from vue to amazon s3 via django REST framework
I'm experimenting Vue with Django and creating a simple blog. But I'm stuck about usage of uploading images vie CKEditor from vue. uploading images to S3 is working within django-admin.

Django: overriding predefined method save() using request data
I'm trying to override the save() method on a Django model so that some fields are automatically filled out. This is the model: class Blog(models.Model): title = models.CharField(max_length=200) user = models.ForeignKey(User, null=True, blank=True, on_delete=models.CASCADE) date = models.DateTimeField(auto_now_add=True) url = models.CharField(max_length=1500, null=True, blank=True) ip = models.CharField(max_length=200, null=True, blank=True) content = models.TextField(null=True, blank=True) def save(self, * args, ** kwargs): if request.user: self.user = request.user self.url = request.path self.ip = socket.gethostbyname(socket.gethostname()) super().save( * args, ** kwargs) What I'm trying to do is to automatically set the user, URL, and IP fields when I save a record, without having to do that in the view. However, in the current format the request is not "passed" to the model, and I'm not sure how I am supposed to do that. This is what I currently get: name 'request' is not defined -

Is it possible to bulk_update a many-to-many relationship in django 2.2?
I have these two simple models: class school(models.Model): name = models.CharField(max_length=128) class teacher(models.Model): schools = models.ManyToManyField(School) user = models.OneToOneField(...) In a view, let's say I wan't to add a school to multiple teachers at the same time. I could do something like this: for teacher in teachers: teacher.add(school) teacher.save() This works, but it is making a lot of queries. Is there a better way to do something like this? I am using django 2.2 (so maybe I could use bulk_update?). -

Uploading a CSV or Excel file along with json data through React html form to Django
I want to submit a form to upload either a csv file or an excel file, and provide additional information provided in the form, e.g. text. For defining the form and sending the request I use React Bootstrap with axios, and for the api I'm using Django 2.2 with rest-framework. request.FILES is always an empty dict, even if I try setting the Content-Type header to multipart/form-data, and then additionally nothing is found in the post data of the request, and printing request.data.get('information') below shows None in the Django log.

How to do complex annotations( and how to think about it!)

Django REST Framework requires hashed password to login
Django requires me to send a hashed password to get my JWT token. When I send the following request via postman I get a "CustomUser matching query does not exist" error. { "user": { "email": "myuser", "password": "mypassword" } } I can, however, run the code with the hashed password (after looking it up from the admin) and it returns the correct value. How do I send unhashed passwords or hash the passwords before I send them? I am using a custom user model that substitutes email for username. I've tried pointing my code to the header using request.META.get("username") and request.META.get("password") but I receive a 'field required' error. I've also tried to figure out how to hash the password on the app before sending it to my API, but I have failed to find a method that works.

Django - Adding extra data in admin change_form request
I'm Customizing Django admin , now i have to add some extra fields which are created by javascript code in fieldset.html template . the reason i wrote these code in fieldset.html is that the inputs will be in main form , so they will be in post request data . Sample of fieldset.html: {% for line in fieldset %} {% if field.field.name == 'discount' %} <input type="number" name="product_code"> . . . <script> this script will create more input fields </script> {% endif %} {% endfor %} But in ModelAdmin.saveModel when i check request data , my input data does not exist. class FactorAdmin(admin.ModelAdmin): def save_model(self, request, obj, form, change): print('request data', request.POST) super(FactorAdmin, self).save_model(request, obj, form, change) is there any other way to include my dynamic html in Django ChangeForm template ? -
how to distinguish authentication status in frontend(vue)

Django CSRF Verification Failed when using WSGIDaemonProcess with multiple processes
My Django version is 2.2 and I've configured httpd.conf to start a process pool like so: WSGIDaemonProcess my_app processes=6 threads=12 display-name=%{GROUP} home=/tmp maximum-requests=1000 inactivity-timeout=1800 request-timeout=500 python-path=${MY_ENV_VAR} With this setup, I would get Forbidden 403 errors with CSRF verification failed message when I do a POST request. If I keep refreshing the page, when I get lucky, my POST request would succeed. Now I'm guessing this is because the request might have landed onto the Django process that has the "right cache". To test the above theory, if I change the httpd.conf to have only 1 pool process like below, I do not get the 403 error. WSGIDaemonProcess my_app processes=1 threads=12 display-name=%{GROUP} home=/tmp maximum-requests=1000 inactivity-timeout=1800 request-timeout=500 python-path=${MY_ENV_VAR} I have followed the CSRF specific instructions on Django documentation and tried both scenarios when CSRF_USE_SESSIONS is set to True or False What is the recommended approach to configuring Django if I intend to spin up a pool for wsgi processes each of which would run my Django app? -

How do I close my camera frame after reading/deciding a qr code with pyzbar?
I've been working on this QR code scanner and so far I've gotten everything to work out; The camera works and the frame shows up. pyzbar decodes the QR codes I show it. regex slices the string I need within the decoded data. Text of the data is shown within the frame. Models are updated accordingly. and lastly I update my list for the time the QR was detected The Problem is I actually want the frame to close when a single QR code is detected, decoded and all of the above process is completed. What actually happens is after the frame is open it constantly and after it detects a QR code, it actually logs multiple (around 15) instances of a QR being detected after like 2 seconds. Also the frame is still up and I can still detect Images. The frame closes, only after pressing the waitkey which is 27 or 'Esc' I've tried adding this: for obj in decodedObjects: id = re.findall('/attendees/confirmation/([0-9]+)', str(obj.data)) cv2.putText(frame, str(id[0]), (50, 50), font, 3, (255, 255, 255), 2) attendee = get_object_or_404(Attendee, pk=str(id[0])) attendee.present = True attendee.timestamp = timezone.now() attendee.time_log.append(attendee.timestamp) attendee.save() if id is not None: cv2.destroyAllWindows() break but obviously that won't work … -
How to restrict access to DetailView depending on user permission AND MODEL ATTRIBUTE VALUE?

So how to restrict that users to view only articles with attribute is_private=True? -

Why does the Django Test Client Post Request on a CreateView Fail to Redirect?
My django.test Client returns a response with status code, 200, when I made a post request instead of redirecting with a status code, 302. I am using Django 2.2.4 with Python 3.7.3. No login is required (as addressed by Why does Django Redirect Test Fail?) neither does setting the follow and secure parameters to True (as addressed by Django test client POST command not registering through 301 redirect) I noticed that the same problem affects my update view. It doesn't redirect when I call the Django Test Client with a put method. (I didn't include this code to avoid verbosity). Finally, I noticed that the page redirect works when I python manage.py runserver and then visit the page to create a new Book instance.
