multilevel user admin in django
Need to create multi level users with roles having same validation for the models as that specified in admin.py, only that each of these users will have different roles.eg. Customer can have different custom_users with diff. roles. A customer can create multiple such custom users with different roles. Each customer can see only his own records in the admin panel. Models: Customer, Custom_user(customer f.key), Role(permission) , customer_customuser(custom_user_id,role_id), But I need to use the same permissions as available in the original django default admin panel for the diff.models like add,edit,delete, view. But have also customized it in admin.py such that each customer can administer using changelist_view and filtering the queryset objects accordingly. How can this be achieved. The models: class Role(models.Model): name = models.CharField(max_length=100, unique=True) permissions = models.ManyToManyField(Permission) def __str__(self): return self.name class CustomUserManager(BaseUserManager): def create_user(self, username, email, password=None): if not email: raise ValueError("The Email field must be set") email = self.normalize_email(email) user = self.model(username=username, email=email) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, username, email, password=None): user = self.create_user(username, email, password) user.is_staff = True user.is_superuser = True user.save(using=self._db) return user class CustomUser(AbstractBaseUser, PermissionsMixin): username = models.CharField(max_length=150, unique=True) email = models.EmailField(unique=True) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) # Specify a related_name below role … -
Adding WeasyPrint to Dockerfile - Django Cookiecutter

How to effectively use django-sso for Single Sign On
Am using django-sso package for SSO(Single Sign On), i have installed it and set the configuration by following the documentation and everything seems to work well.

Codecov coverage considers wrong files on Django app
I have been using codecov on my projects to produce test coverage, among others, a Django app. I could upload by hand after each push, but there are GitHub actions to perform this automatic action for me, right!? I wrote the yml file below to perform such a pipeline. However, there are two problems, from my perspective: It must consider ONLY application folder src!

How can I set a default value in an inline admin?
Let's say I have a NarratorAdmin page to display and change details of the Narrator model. It includes a BookInline where the narrator's Books can be changed, added or deleted. Not all of Book's fields are present in the BookInline-- only the most "important" ones. Let's further imagine that Book has a "category" field, with values like print, digital, hybrid, audiobook. When a Book is created from the NarratorAdmin page, I want to automatically set its "category" to "audiobook". "category" is NOT included in BookInline.fields. The user doesn't need to see it and it doesn't make sense for them to change it. I've tried the following methods (all suggested by AI): def get_formset(self, request, obj=None, **kwargs): formset = super().get_formset(request, obj, **kwargs) formset.form.base_fields['category'].initial = "audiobook" return formset (Doesn't work because "category" is not in base_fields) def save_model(self, request, obj, form, change): obj.category = 'audiobook' super().save_model(request, obj, form, change) (After adding some print statements, I don't think this method is actually being called) def save_formset(self, request, form, formset, change): instances = formset.save(commit=False) for instance in instances: instance.category = 'audiobook' instance.save() formset.save_m2m() Similar to the above, this one doesn't seem to be getting called when I expected it to. -

Django Ninja Update a FileField
I am trying to create a simple restful API using Django-ninja.

Django query not respecting order for ltree field subquery (Postgresql)
Background I have an application that uses a team model that includes a field using the ltree postgres extension, which is a field that allows you to store the entire ancestral chain of an object including itself in a single field (the representation I see is . separated id values). This field type is not supported by Django out of the box, so some custom extensions were added to add proper support for the ancestor/descendant checks that I think are based on some packages available that do some of the same. This ltree field is being used as a path column in our Team table in the database to store team hierarchies. The Problem There is an export option that will generate a CSV copy of the team structure, and as part of that, a given team will have the ancestors display each in their own columns next to other information about the team. When some larger teams are exported, the order of the ancestors is scrambled. Some digging shows that the subquery used to create the list annotation that explodes the path into individual teams is not respecting the ordering provided in the subquery. The basic query that is … -

Session cookie for multiple domains. Security concerns
I think this is kind of a trivial question, but I got an idea that I want to share and ask if it is even necessary. I have 3 react apps as 3 different subdomains - auth.site.com, client.site.com and admin.site.com, and a django backend at api.site.com. Now it works like this: User logins from auth, through api.site.com Django sets session cookie with Domain=.site.com User is redirected to the allowed react app (client or admin) But... This way I can't set the cookie to specific react app subdomain, because Set-Cookie header is sent from api and browser rejects it if domain is not .site.com Second approach: User logins at auth User is redirected to, for example admin.site.com/internal/setcookie/<long_long_token> (web server sends these /internal/* paths to django instead of react) At that view, django gets the session from this one-time <long_long_token>, and sets the cookie with Domain=admin.site.com. User is redirected to / Considerations First of all, I wonder if can I even use this, will the browser not send cookies to api.site.com when session cookie has a Domain=admin.site.com? Also, I don't like that if user logins and is redirected to client, he can still just change subdomain to admin and will still have … -
How to know if a 500 error is raised in DRF exception handler?
I am creating a custom exception handler in django rest. I want to determine if incoming exception is a 500 exception or related to 500 exceptions. from rest_framework.views import exception_handler def custom_exception_handler(exc, context): response = exception_handler(exc, context) if response is not None: response.data['status_code'] = response.status_code return response The problem is response status code is determined only when exception is related to serializer or a explicit response with 500 error code is raised. When I try to raise a python exception like ValueError, the response is None. And there is no way to know if exception is 500 or should be 500. I need to know if exception is a 500 error in my custom exception handler. What should I do?
