Will Django channels good for to use asynchronous long running background functionality
While working on request where i need to do long running bulk operation on backend ( which takes almost 15-30 min now) for each individual user to avoid load on database. I see Django channel with Redis as channel layer can helps to achieve this. Will that be good fit to do this as asynchronous long running job separately using Django channels. I saw mostly its used for real time communication not sure will that used for my purpose also. Please suggest thoughts will that be right approach or any other option should i use to perform long running background functionality while using Django. No option tried just explored django channel -
Linkedin 3-legged OAuth throws 'Not enough permissions to access: GET /userinfo'
I was trying to integrate social login for my Django application using linkedin OAuth2. I have followed steps described in their official page here. In step2, I have given 'profile' value for scope parameter, given below are the allowed scopes in my app. The scopes listed in my linkedin app page. I have successfully completed up to step3, and I got access_token successfully. But when I tried an authenticated request using that access token for example, curl -X GET https://api.linkedin.com/v2/userinfo, I am getting an error like b'{"serviceErrorCode":100,"message":"Not enough permissions to access: GET /userinfo","status":403}'. I have tried v2/me, getting the same permission error.

Questions regarding react in django or react as standalone
I am creating an website using react and Django. To combine Django and react there are 2 ways React in its own “frontend” Django app: load a single HTML template and let React manage the frontend (difficulty: medium) Django REST as a standalone API + React as a standalone SPA (difficulty: hard, it involves JWT for authentication) Now my questions are What are security concerns related to both and which of them is more secure way to do it. In Option-1 we can use both session and token based authentication while in Option-2 we must use token based authentication and XSRF header is needed. Is session based auth better and in what factors it effects If in future I plan to move to react Native for mobile app, which would be more suitable. (I could not find any example when using Option-1) Apparently, Instagram is using session based auth, which means they have used Option-1. Are Option-1 sites SPA based and is Insta SPA based. An extra unrelated question, which is better JWT token auth or Django knox auth. If JWT is better please refer any guide on integrating it with Django. -
jwt decode giving empty username in django unittest while using request.META

Django giving error when trying to get path to static file
I'm trying to implement xhtml2pdf, and in my html file, it references a static file. I have the file in my project at jobs/static/jobs/style.css. When using the code xhtml2pdf provides in their docs, I am getting an error when it gets to result = finders.find(uri) saying django.core.exceptions.SuspiciousFileOperation: The joined path (/static/jobs/css/style.css) is located outside of the base path component (/opt/project/myproject/static). If I navigate to the url that the file should be at, http://127.0.0.1:8000/static/jobs/css/style.css, I see the code of the css file, so it is in the generally correct location. This project is being served in a docker container, and there is nothing stored in /opt, so I don't know why it coming up with this "base path component" at (/opt/project/myproject/static).

Modifying request contents in DRF
As far as I know request objects are immutable and it's bad practice to modify request through closed attributes like request._body or request._data. And since it described everywhere as bad practice, I'm lack of details to understand why it's should be avoided. What is the best approach to dynamically change request (for example if we need to decode value in request.body). As I alternative I can imagine custom Serializer with custom decode serializer.Field but maybe there's more clever solution? Thank you in advance! -

Django checkbox input only working in one direction
I have a form with a checkbox on "pregnant". If the profile is not pregnant and goes to the update profile form, checking the box and submitting the form updates the profile. I can see in the dashboard it appears as pregnant now. However, if the profile is pregnant, and goes to update profile, unchecking the checkbox (prepopulated) and submitting, it does nothing! The profile information does not update (it still appears as pregnant in the dashboard). I am puzzled because the form connects to the database (it can update from non-pregnant to pregnant) but not the other way around! What am I missing? :-/ See my code. view: def edit_profile(request): if request.user.is_authenticated: current_user = Account.objects.get(id=request.user.id) form = EditProfileForm(request.POST or None, instance=current_user) if form.is_valid(): form.save() messages.success(request,("Your profile has been updated!")) return redirect('dashboard') return render(request, 'accounts/edit_profile.html',context={'form':form}) # else: messages.success(request,('You must be logged in!')) return redirect('login') html: <div class="flex col col-auto form-group form-check"> <label><input type="checkbox" id="pregnancy" value="Yes" name="pregnancy" {% if form.instance.pregnancy == 'Yes' %} checked {% endif %}> {% trans " Pregnant" %}</label> </div> model: class Account(AbstractBaseUser): .... pregnancy = models.CharField(max_length=10,blank=True, null=True, default='No') -

I created the following models. difficulty_choices=(('easy','easy'),('hard','hard'),('medium','medium')) class Quiz(models.Model): name=models.CharField(max_length=200) topic=models.CharField(max_length=100) number_of_questions=models.IntegerField() difficulty=models.CharField(max_length=100,choices=difficulty_choices) def get_questions(self): return self.questions_set.all()[:self.number_of_questions] class Questions(models.Model): text=models.CharField(max_length=200) quiz=models.ForeignKey(Quiz,on_delete=models.CASCADE) correct=models.CharField(max_length=25) def __str__(self): return str(self.text) def get_answers(self): return self.answers_set.all() class Answers(models.Model): text = models.CharField(max_length=200) question = models.ForeignKey(Questions, on_delete=models.CASCADE) def __str__(self): return f"Question: {self.question.text}, Answer: {self.text}" class UserAnswer(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) question = models.ForeignKey(Questions, on_delete=models.CASCADE) answer = models.ForeignKey(Answers, on_delete=models.CASCADE) selected=models.CharField(max_length=25,blank=True) The text field in 'Answer' model contains the options and text field in 'Question' model contains the question The option for each question is displayed in the form of radio select button. The UserAnswer model saves the answer answered by the authenticated user, for each question. To be able to select the option i created the below forms.py class QuizForm(forms.ModelForm): class Meta: model = Questions fields = ['text'] # Add other fields as needed def __init__(self, *args, **kwargs): super(QuizForm, self).__init__(*args, **kwargs) question_instance = kwargs.get('instance') answers = question_instance.get_answers() answer_choices = [(answer.text, answer.text) for answer in answers] self.fields['selected_answer'] = forms.ChoiceField( label="Select the correct answer", choices=answer_choices, widget=forms.RadioSelect ) and the views.py for this is @login_required def questions(request, pk): try: … -
