Django CORS denying access even though I've set CORS_ORIGIN_ALLOW_ALL = True
I've got 2 separate projects and project A needs to access some things from project B. I've already installed CORS on project B but accessing its resources from project A still raises the following error: Access to XMLHttpRequest at 'http://api.example.com/api/spotify/1IJxbEXfgiKuRx6oXMX87e' from origin 'http://127.0.0.1:8000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. CORS on project B is set to CORS_ORIGIN_ALLOW_ALL = True. Am I missing an additional setting or something? -

email already exists while updating user in django rest framework
I was updating the User when faced email already exists crossed my way. how ever i could use the extra_kwargs to overcome the email already exists or phone already exists issue. and then using from django.core.validators import EmailValidator in extra_kwargs as "email": {"validators": [EmailValidator]}.. bring back my email field validations. but that don't seems as a real solution. As we are just updating the existing model object.. why It's behaving like we are creating a new one. I think there should be something as defining update or partial_update or i don't know what ever.. is there any other solutions for this ?? class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = "id", "full_name", "gender", "phone", "email", "date_of_birth" extra_kwargs = { # "phone": {"validators": []}, # "email": {"validators": [EmailValidator]}, } -

Django: How to implement transaction rollback in database if there is insertion in more than one model consecutively?
I am pretty new to Django and I have searched for this topic on the internet but I am not understanding. Basically, I am creating a student user which will be linked to the built-in User model in Django. In my code, I create the user in the user model first then I create it in the StudentUser model. However, if ever an error occurs, maybe the StudentUser was not created, I want to undo the changes in user. How to go around this with rollback? Here is my code snippet: views.py def user_signup(request): if request.method == 'POST': # Signup for student if(request.POST['stud_fname']): stud_fname = request.POST['stud_fname'] stud_lname = request.POST['stud_lname'] stud_uni = request.POST['stud_uni'] stud_email = request.POST['stud_email'] stud_password = request.POST['stud_passwd'] try: user = User.objects.create_user(first_name=stud_fname, last_name=stud_lname, username=stud_email, password=stud_password) StudentUser.objects.create(user=user, university=stud_uni, user_type="Student") messages.success(request, "Account successfully created.

REST API taking too much time to respond
I have built an API using Django & django-rest-framework. The Django Server is currently deployed on Heroku's Free Hobby Dyno. this is how my API call looks right now, GET https://feasta-postgres.herokuapp.com/menu/get_category/?admin_id=5 I am currently testing my API through POSTMAN. PROBLEM I have noticed that when I call this API for the First time, it takes too much (~1 second) time to respond. Then it becomes Faster for the subsequent calls. Then after some interval it again becomes slow. This is the event waterfall for my first request call, This is the event waterfall for my subsequent request calls, As we can see in the first image, the handshakes are eating up most of the time. Questions Is there any way to optimize the first request? If yes then How? Will this also occur when I call this API from a Deployed React website or is this only a Postman problem? My Best Guess I am using a Free Heroku Dyno, that's why Heroku is being "lazy" to process my request. Upgrading it to the paid one will do my job.
