Fetch API with blocked CORS policy vs Fetch API not blocked
I have 2 API endpoints on a server. However, 1 API call is successfully called, while the other is blocked by CORS policy. Both are also called with the same fetch API in react. I can't tell the difference in how I am calling them which resulted in one of the requests being blocked. In my django settings, I have set CORS_ORIGIN_WHITELIST to my the domain name and CORS_ORIGIN_ALLOW_ALL = True My react API call for both starts something like that: fetch("http://127.0.0.1:8000/createdeepfake", { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify(data_fake), }) .then(response => {...

How do I link a specific field of my two django models with each other?
I have two different models in my django database. One for my companies and for my contacts as follows: companies.models: from django.db import models class CompaniesDetailView(models.Model): name = models.CharField("Enter Company Name", max_length=50) email = models.EmailField("Enter Email") phone_number = models.CharField("Enter Phone Number", max_length=12) contact_name = models.CharField("Enter Contact Persons Name", max_length=50) company_image = models.ImageField(default='default-avatar.png', upload_to='companies/', null=True, blank=True) def __str__(self): return '%s' % (self.name) contacts.models: from django.db import models from apps.companies.models import CompaniesDetailView class Contact(models.Model): name = models.ForeignKey(CompaniesDetailView, on_delete=models.CASCADE) email = models.EmailField("Enter Email") phone_number = models.CharField("Enter Phone Number", max_length=12) company_name = models.CharField("Enter Company Name", max_length=50) contact_image = models.ImageField(default='default-avatar.png', upload_to='contact/', null=True, blank=True) def __str__(self): return '%s' % (self.name) Now I want to link the two models such that when I create a company through Django an additional contact will be created from the contact_name of CompaniesDetailView. Currently if I try to create a contact it is taking the name of the companies. I know the solution is simple but I can't seem to grasp it. -

How to send push notification to a browser endpoint using django?
I have created a javascript program which send push notification requests to browser and when the user allows the push services then the browser endpoint details are sent to a django view (say fetch_browser_endpoint()) using $.post() The view stores the endpoint details in a database successfully.

is there any way to run React + Django in same project without running npm run build again and again?
I have enough knowledge about Django and recently learned react and i like to combine both. I have gone through a couple of video tutorials and i am successful in integrating them. but the problem is i should either build a rest API and a react app in two different projects and them combine them or i need to run npm run build every time i make any changes on my front end. so if anybody have an alternative for this(Running React on Django server continuously without running build again and again) please tell me. please don't downvote this since i am new to this platform i will learn things slowly. -

Django Auth User and Custom User
So far, I have been creating a user class in Django without inheriting AbstractBaseUser or AbstractUser classes. For example, class User(models.Model): realname = models.CharField(max_length=50) username = models.CharField(max_length=50, unique=True) birthday = models.DateField() phone = models.CharField(max_length=50, unique=True) password = models.CharField(max_length=2000) ... Now I am thinking about creating a user model that actually inherits AbstractBaseUser class. My question is, in what ways does inheriting AbstractBaseUser increase efficiency and productivity, if any? I guess set_password() function may relieve the burden of manually encrypting input password with bcrypt; however, additional work is needed to create a UserManager class, refer to my custom User model with auth.get_user_model() function (django documentation says this way is recommended to return the currently active user model) instead of simply referring to it as 'User', and etc. Your help will be greatly appreciated!! -
