How to use django_simple_jwt for sending the token as soon as user signs up?
Hi All I have a code from https://medium.com/@dakota.lillie/django-react-jwt-authentication-5015ee00ef9a which uses django rest_framework_jwt for responding Token with the user sign up importing libraries from rest_framework import routers, serializers, viewsets from django.contrib.auth.models import User, Group **from rest_framework_jwt.settings import api_settings from rest_framework_simplejwt.serializers import TokenObtainPairSerializer** Serializer:- class UserSerializerWithToken(serializers.ModelSerializer,TokenObtainPairSerializer): email = serializers.EmailField(required=True) username = serializers.CharField() password = serializers.CharField(style = {'input_type':'password'}, min_length=8, write_only=True) token = serializers.SerializerMethodField(source ="get_token") def get_token(self, obj): **jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER** payload = jwt_payload_handler(obj) token = super(obj).get_token(payload) return token def create(self, validated_data): password = validated_data.pop('password', None) instance = self.Meta.model(**validated_data) if password is not None: instance.set_password(password) instance.save() return instance class Meta: model = User fields = ('token', 'email','username', 'password') and the views :- """ class UserList(APIView): """ Create a new user. It's called 'UserList' because normally we'd have a get method here too, for retrieving a list of all User objects. """ permission_classes = (permissions.AllowAny,) def post(self, request, format=None): serializer = UserSerializerWithToken(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) Now I want to convert all the serializer setting from rest_framework_jwt to rest_framework_simplejwt as the former is not being actively maintained. I am having issues in what to replace in jwt_payload_handler, jwt_encode_handler and payload for rest_framework_simplejwt. -

Django assigning multiple models to single model
I am wanting to create a way to add the players of a team into my admin panel. Then I want to load in a years worth of events for the team. Then when creating a list, I want to select each persons name and then multiselect all the events they are going to and assign it to my event roster. class Person(models.Model): name = Charfield(max_length=100) class Event(models.Model): name - Charfield(max_length=100) ....more fields.... class List(models.Model): upcoming_events_list = ??? In my head it would look like this.. Mary Ann: Event1 Event2 Event3 John Pilgrim: Event4 Event9 Rusty Spoon: Event13 Event99 Event2 Event4 etc... I will eventually want to be able to create multiple event rosters. So I could have a Home Roster, Away Roster, Playoff Roster, etc. Where I can reuse the players names and events on each of these rosters. Then when I want to filter through the list for a certain name how would I be able to do that? I am new to the admin page and Django in general but it would be nice to login and select 'Names' and add all the players. Then go to 'Events' and add all the event details. Then go to … -

Django: How can I assign a variable ForeignKey to data collected in forms?
My goal is to be able to add "weight" values to my existing lists. The weights correspond to an exercise by ForeignKey which in turn the exercise relates to a specific workout.

REST API, JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
I have a django based website with user profiles system where users can add notes. I am trying to implement CRUD via REST Framework.

Problem with setting up datetimepicker in Django

Django model field having multiple dictionary options
I am running into an issue and this is a replica in a smaller scale of what I am running into.. class Garage(models.Model): vehicles = models.CharField(max_length=255) What I want to store in my garage is multiple vehicles. And I want each vehicle to be a Make and Model. So I was thinking I could do something like this.. class Make(models.Model): make = models.CharField() class Model(models.Model): model = models.CharField() Then I can specify in my Garage class any amount of Make:Model objects and assign them to the vehicles field. So then essentially, vehicles would like like: {'Ford':'Mustang', 'Chevrolet':'Camaro', 'Dodge':'Charger'} -
Django formset, pass initial value and save to different model
I am trying to pull initial data from existing objects and save them as new object. The situation is like, user tries to submit their education information for review. If user has pre-saved education information, bring the initial values from the object and pre-fill the forms of the education. When user saves it, it does not change the original object, but makes new object. I tried to bring original value and save the formset as education_form = ResumeEducationFormSet(request.POST, instance=resume, prefix='education') but it shows the "inline value does not match the parent instance". I get why I am getting this error, but I can't find the way to just bring the initial values. I can do the (initial={}) thing but it is hard it there are multiple objects. How can I solve this problem? -

Python Cloud Programming
I'm new in python and trying to develop my projects. I've been using tkinter module to code my programs so far. As you may notice tkinter works in local machine and does not allowed you to use the data from another computer(at least I know that so far). Now I'm in need of developing my project as a website but I don't know which way to go. I'm planning to open a website and code my program in there as well as I need to save program user informations(user name, password, their data's) in my website cloud server. I've been searching django, tkinter and other GUI modules to decide my way to code but I couldn't find the best proper way. If you have any recommendations I really appreciate it. -

This is the code I have so far, I started off with the getting started code on the chartjs site <div class="chart-container"> <canvas id="myChart"></canvas> <script src="https://cdn.jsdelivr.net/npm/chart.js@2.8.0"></script> <script type="text/javascript"> var ctx = document.getElementById('myChart').getContext('2d'); var chart = new Chart(ctx, { // The type of chart we want to create type: 'line', // The data for our dataset data: { labels: [{% for d in data %} "{{ d.date }}", {% endfor %}], datasets: [{ label: 'My First dataset', backgroundColor: 'rgb(255, 99, 132)', borderColor: 'rgb(255, 99, 132)', data: [0, 10, 5, 2, 20, 30, 45] }] }, // Configuration options go here options: { responsive:true, maintainAspectRatio: false } }); </script> </div> -
Django CropperJS CropperImageField doesn't save the cropped image
I developed an app in Django and in Admin Panel, when adding an Image to my Model, I need to crop it (but it's not a standard crop, so I need to do it manually, by drag and drop for every new image added). So I found CropperJS that fits perfectly. I pip installed CropperJS, I ran it and it works (the modal shows up and I can crop the image, I see the preview of the cropped image), but the problem is that when I press "Save", the picture just don't save. The CharField(name) saves. My code: class ImageTest(models.Model): image_field_crop = CropperImageField(upload_to='images/', default=None, null=True, blank=True) name = models.CharField(max_length=50, default=None, null=True, blank=True) -
Django set_wakeup_fd only works in main thread
I have uploaded my django web app to my windows server using WAMP apache web server. Everything works well and as expected, however occasionally when i try to load a page, i get thrown this error.

My windows server is running windows server 2008 rc2. Has anyone else encountered this error and/or know of a way to stop it? -

Django admin able to upload images to S3 bucket but doesn't load on template
I was able to upload images to my s3 bucket via django admin however, the images do not load on the HTML page. I followed the documentation and checked some tutorials and other solutions but none worked so far. I tried adding the region name of my s3 bucket but this didnt worked either. I also tried making the bucket public but to no avail. This is my settings.py: AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME') AWS_S3_REGION_NAME = os.environ.get('AWS_S3_REGION_NAME') AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' Upon inspecting element and viewing the image, I am greeted with this error: this lead me to the trying out making the bucket public and configuring utils.py (https://stackoverflow.com/a/53976351/9615990) which didnt work.
