How do I view the profile of the authenticated user in Django Rest Framework using the Token
I am learning DRF and creating a simple DRF app that lets user login, and view the profile and update the profile. I am using Django's default User model and using Knox for Token Authentication (if it can be done easier using Django Rest Authentication, please let me know and also tell me the procedure). I have successfully created the API to register and login the user which works fine, but I am stuck at showing the profile to the Authenticated User through a Token. I am only one Model that is Details which acts as to store the Profile details of the user. I have LoginSerializer which is connected to Login API and MainUserSerializer & UserSerializer, both of which are connected to User API (which acts to show the Profile details on frontend). I have tried a lot, searched everywhere, but all they show is how to authenticate the user with token through a url (some thing like using curl https://localhost:8000/api/user... etc.), postman, somehing like http post -a... command in terminal and other ways, but I don't want to test or implement using these ways. I want something that if I open my user profile url after logging in … -

Django extend `UserManager` instead of `BaseUserManager`
Django docs says to define a custom manager you have to extend the BaseUserManager and provide two additional methods. But after doing so, I realized that my custom manager is vary similar to the default UserManager. So, is there a problem with inheriting from that instead? Like this: from django.contrib.auth.models import UserManager class CustomUserManager(UserManager): """Custom user model manager with email as the unique identifier.""" def _create_user(self, email, password, **extra_fields): if not email: raise ValueError("The given email must be set") email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user I just overrode the _create_user method, because others were identical. -
ArrayField consisting of composite field type
I have modeled composite field using https://pypi.org/project/django-composite-field/ in my django model (A URL field + a Boolean Field).

What I want is a list of the object (URL + boolean) for every user. Further I want to add validations for the number of objects eg.(min 2 objects, max 6 objects). What is a good way to model this? Thanks. -
django-tenants: access tenant media files in script
I am running an app built with djang-tenants. The app asks the user (tenant) to upload some data. I want the data to be segregated in sub directories for each tenant. Acccording to the doc (https://django-tenants.readthedocs.io/en/latest/files.html), here is how media root is configured: settings.py MEDIA_ROOT = "/Users/murcielago/desktop/simulation_application/data" MULTITENANT_RELATIVE_MEDIA_ROOT = "%s" On the upload everything is great. Now, I can't find a way to retrieve the file being uploaded within the app. Basically I need the app to serve the file corresponding to which tenant is requesting it. Here is how I thought this would work: from django.conf import settings media_file_dir = settings.MULTITENANT_RELATIVE_MEDIA_ROOT df = pd.read_csv(media_file_dir+'/uploads/sample_orders_data.csv') but this does not work. I have made it work so far grabbing the tenant name from the url and passing it to the app using pickle but this is not right in terms of security and won't scale. Would someone has a clue on the best way to handle the lecture of tenant specific files? -
