Chained Dropdown in ModelFormset_Factory - Django
I want chained dropdown list in model formset. I have 4 models in my app App_Prod - Category, Product, OrderInfo, Order In my form, I used two views combinely.

How can I filter items in DjangoRestFramework?
I am complete beginner and I made a django project a while ago. Its main purpose is adding restaurants and categories and food menu respectively. For now, it is working well, if I go to the required restaurant, it shows its categories. But now, I want to improve it via Vuejs and that's why I'm trying to make Django REST API. But I can't filter categories and food according to their restaurant, because category model is not directly connected to restaurant model. My models.py is: from django.db import models from django.conf import settings class Restaurant(models.Model): owner = models.OneToOneField(settings.AUTH_USER_MODEL, related_name="restaurant", on_delete=models.CASCADE) name = models.CharField(max_length=256, db_index=True) slug = models.SlugField(max_length=256, unique=True) logo = models.ImageField(upload_to='logos/', blank=True) def __str__(self): return str(self.name) class Category(models.Model): name = models.CharField(max_length=256, db_index=True) slug = models.SlugField(max_length=256, unique=True) icon = models.ImageField(upload_to='categories/', blank=True) class Meta: verbose_name = 'category' verbose_name_plural = 'categories' def __str__(self): return str(self.name) class Food(models.Model): restaurant = models.ForeignKey(Restaurant, related_name='foods', on_delete=models.CASCADE) category = models.ForeignKey(Category, related_name='foods', on_delete=models.CASCADE) name = models.CharField(max_length=256, db_index=True) slug = models.SlugField(max_length=256, blank=True) price = models.IntegerField(default=0) description = models.TextField(blank=True) image = models.ImageField(upload_to='foods/', blank=True) available = models.BooleanField(default=True) def __str__(self): return str(self.name) As you see, category class is not directly connected to restaurant.

Django, how to set group based permissions
I am working on a project which has different types of users. Each group of user should be able to access some pages and be restricted to access other pages. I saw various solutions for this like. Some assign users to specific groups and then write a custom decorators to restrict pages like def allowed_users(groups=[]): def decorator(view_func): def wrapper_func(request, *args, **kwargs): group = None if request.user.groups.exists(): group = request.user.groups.all()[0].name if group in groups: return view_func(request, *args, **kwargs) else: return HttpResponse("You are not authorize to view this page ") return wrapper_func return decorator @allowed_users(groups=["admin"]) def products(request): pass and some tutorials and books recommend to assign user to groups and then give permissions to each group. like admin_group.set.permissions([list_of_permissions]) admin_group.add.permissions(per1, per2, ...) a quote which says Note: do not check the user in the group to verify whether the users have permission or not, so must use has_perm because at the bottom line user will inherit the permissions from the assigned groups and you can use groups to categorize users if your intention was just to use a User Role model alternative. My question is, which method is appropriate and why? and if we prefer the first method doesn't it break the role … -

Python TikTokApi SynchronousOnlyOperation error
I have a Django project where I am trying to fetch TikTok user info from a class based django view. I am running into an issue that appears to be related to async/sync/threading. Related documents: https://docs.djangoproject.com/en/3.2/topics/async/ I tried decorating views described in the link above still no luck. I added this bit of code to my gunicorn wsgi file os.environ.setdefault("DJANGO_ALLOW_ASYNC_UNSAFE", "true") which does fix the problem but seems like a bad idea. Here is the bit of code that I am using to call the TikTokAPI: def get_user_info(username): verify_fp = "code here" try: api = TikTokApi(custom_verify_fp=verify_fp) user = api.user(username=username) info = user.info_full() return info except Exception: return None class TikTokAccount(APIView): def post(self, request, *args, **kwargs): ... info = get_user_info(username) ...
