How to add Authenticate Middleware JWT django REST?
I'm a begginer in using Django and REST. And in my project I have to add custom JWT auth. I've tried to generate it like this inside of User model: class User(AbstractUser): .... def _generate_jwt_token(self): dt = datetime.datetime.now() + datetime.timedelta(days=60) token = jwt.encode({ 'id': self.pk, 'exp': int(dt.strftime('%s')) }, settings.SECRET_KEY, algorithm='HS256') return token.encode("windows-1252").decode("utf-8") In my views I did class LoginAPIView(APIView): def post(self, request): ... response = Response() response.set_cookie(key="jwt", value=user.token, httponly=True) ... return response And class CurrentUserAPIView(APIView): def get(self, request): token = request.COOKIES.get('jwt') if not token: raise AuthenticationFailed('This user is unauthenticated') try: payload = jwt.decode(token, settings.SECRET_KEY, algorithms=['HS256']) except: msg = 'Invalid authentication. Could not decode token.' raise AuthenticationFailed(msg) try: user = User.objects.get(pk=payload['id']) except User.DoesNotExist: msg = 'No user matching this token was found.' raise AuthenticationFailed(msg) serializer = UserSerializer(user) return Response(serializer.data, status=status.HTTP_200_OK) But I think this logic has to be inside a middleware. Could you give me an advice how can I rewrite this code. Thank you so much! -
Django URLfield st
Trying to build Django Models with Django rest_framework serializers. Models should store list of URLs searched by a user and the serializer should help return combination of those urls. Got it to work based on documentation and two answered questions (first, second), but cannot figured how to get a desired formatting: unpack a list of dictionaries inside returned rest_framework response. Current api output looks like that: What I would want is for links to be just a list of urls instead of dictionaries. models.py (short version): class User(AbstractUser): pass class Combo(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='searches') updated = models.DateTimeField(auto_now = True) created = models.DateTimeField(auto_now_add = True) class ComboLink(models.Model): combo = models.ForeignKey('Combo', on_delete=models.CASCADE, related_name='links') link = models.URLField(null=True, blank=True) serializers.py: class ComboLinkSerializer(ModelSerializer): class Meta: model = ComboLink fields = ['link'] class ComboSerializer(ModelSerializer): links = ComboLinkSerializer(many=True) class Meta: model = Combo fields = ['user', 'id', 'created', 'links'] -

Input value Set using jquery's selector does not post
there's this issue where I created a form using django. The form contains two charfields for name and address, and two datetimefields one for a start_date and the other for a stop_date. Finally there are two radio buttons, such that: when the first is checked, the start_date field's value is set to date.now() using jquery's selector when the second radio button is checked, the start_date and stop_date fields are disabled, still using jquery's selector. The above code works well. However, when the start_date's value is successfully set, I have to post the form data using jquery ajax post method to a django view, the start_date's value is not posted at all, while the other field values are. I don't know how to go about this issue. Here's my code template.html {% extends 'base.html' %} <div class="center"> <form action="" invalidate> {% crispy form form.helper %} </form> </div> script.js $('input:radio').click(function){ if ($(this).val() === '1'){ var start_date = new Date(); $('#id_start_date').val(start_date); } else if ($(this).val() === '0'){ document.getElementById('id_stop_date').disabled = true; document.getElementById('id_start_date').disabled = true; } } $("form").on("submit", function (e){ var name = $("#id_name"); var type = $("id_type"); var start_date = $("id_start_date"); var stop_date = $("id_stop_date"); $.ajax({ type:"POST", url:"{% url 'postAccount' %}", data:{ csrfmiddlewaretoken: document.querySelector('input[name="csrfmiddlewaretoken"]').Val(), … -

How to implement OpenID Connect with multiple providers in Django?
I'm trying to implement multiple SSO (OpenID Connect) logins in my application, besides the regular one. The current provider requests are Azure and Okta, but there will be more. For every bigger customer using my application, I want to be able to enable them a custom SSO login that they can setup in the admin panel. All the libraries I've tried using for this are either using settings.py and local django authentication, or they are deprecated. The flow is like this: User chooses their company and SSO login button -> Gets redirected to login -> I send the client id, secret etc. (which they entered in the admin panel when registering an sso connection) -> I get a token in return with the users name and email -> with this info (email) I find the already existing user in my local database and log him in -

Dealing with the environment url in the "build" version of react
I'm trying to deploy a react-django app to production using digitalocean droplet. I have a file where I check for the current environment (development or production), and based on the current environment assign the appropriate url to use to connect to the django backend like so: export const server = enviroment ? "http://localhost:8000" : "domain-name.com"; My app is working perfectly both on development and production modes in local system (I temporarily still used http://localhost:8000 in place of domain-name.com). But I observed something rather strange. It's the fact that when I tried to access the site (still in my local computer) with "127.0.0.1:8000" ON THE BROWSER, the page is blank with a console error "No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' ....". When I changed it back to "http://localhost:8000", everything was back working. My worry is isn't 127.0.0.1:8000 the same as http://localhost:8000? From this I conclude that whatever you have in the domain-name.com place when you build your react frontend is exactly what will be used. Like I said, I'm trying to deploy to a digital ocean droplet, and I plan to install ssl certificate so … -

Django 4 update form fields dynamically using HTMX
I developed a Django application in which i have a form with some fields. Depending on the input additional fields are displayed are hidden. Now everything worked quit fine in Django 3.2.14 since the update in Django 4.0.6 it didn't worked anymore.

Migrating data from a JSONfield to individual fields
I have a DJango Model class in which it was decided to store a bunch of data in a blob form. The reasons for this decission are not clear to me ... Regardless I now have the task of converting that JSONField into individual Model fields. My question is, how would I go about creating a custom DJango migration that would extract the data from the JSONField and migrate it into the new fields? My first idea is to make a migration in which I add all the new fields, then a second migration that will be custom made. In this second one I will use the django orm to go through every instance of my model and extract the JSON data and then loop through the field structure and alter the newly added fields with the JSON values. The only issue that I could see is if the fields have special constrants then it would get pretty tedious to get everything wright. Any suggestions on my approach?
