Django: How to control permissions based on a complex query
I am creating an application using the django rest_framework. I have the following models: Employee (Many to one relationship to Project) Project (Many to one relationship to Manager) Manager The Manager should be able to see all Employees that are not currently assigned to a project, or that are assigned to a project that the Manager is managing. (There can be other managers that assign an employee to their own project, and then other managers can't see them). These are the libraries that I am using: asgiref==3.4.1 Django==3.2.6 django-filter==2.4.0 django-rest-framework==0.1.0 djangorestframework==3.12.4 pytz==2021.1 sqlparse==0.4.1 I'm imagining something like this: class Employee(models.Model): name = models.CharField() assignment = models.ForeignKey('Project', on_delete=models.SET_NULL, null=True, blank=True, related_name='assigned_to_project') class Project(models.Model): name = models.CharField() owner = models.ForeignKey('Manager', on_delete=models.SET_NULL, null=True, blank=True, related_name='managed_by') class Manager(models.Model): name = models.CharField() As far as permissions, I imagine a custom permission on the employee which is something like: def has_permission(self, request, obj=None): if obj: if obj.assignment is not None: """ Start sudo-code - Use the value saved in obj.assignment (for example the PrimaryKey of the project it is assigned to) - Follow that PK to the project table, and look to see if obj.owner is not None. - If it isn't None, take the PK … -

"The file cannot be reopened." error from django-imagekit after moving a file
I'm using django-imagekit to generate a thumbnail on a Django model: class Book(models.Model): title = models.CharField(null=False, blank=False, max_length=255) thumbnail = models.ImageField( upload_to=upload_path, null=False, blank=True, default="" ) list_thumbnail = ImageSpecField(processors=[ResizeToFit(80, 160)], source="thumbnail", format="JPEG") That works fine. However I'm trying to move the original thumbnail file after upload. Here's a simplified version of my save() method, that just moves the file into a "new" directory and re-saves the object (it's more complicated than that really): def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.thumbnail and "/new/" not in self.thumbnail.path: # Move the thumbnail to correct location. initial_name = self.thumbnail.name initial_path = self.thumbnail.path new_name = os.path.join(os.path.dirname(initial_name), "new", os.path.basename(initial_name)) new_path = os.path.join(settings.MEDIA_ROOT, new_name) if not os.path.exists(os.path.dirname(new_path)): os.makedirs(os.path.dirname(new_path)) os.rename(initial_path, new_path) self.thumbnail.name = new_name kwargs["force_insert"] = False super().save(*args, **kwargs) This works fine by default. But if I have this in settings.py: IMAGEKIT_DEFAULT_CACHEFILE_STRATEGY = "imagekit.cachefiles.strategies.Optimistic" then I get errors resulting from imagekit signals, presumably confused that the file has moved while trying to generate the list_thumbnail.

Django Rest Framework - general approach on handling guest users
I'm trying to implement handling of guest (anonymous) users in my Django/React app using DRF, but I'm not sure exactly how to proceed. What I want eventually is, when a non-registered user comes to my homepage, he can perform limited CRUD operations eg. creating a maximum of 10 tasks, and when he chooses to register, these limitations are then lifted. A while ago, I did the same app but only with Django, and the way I had it set up, was when an anonymous user visited the page, a new user was created without a password. I was using this function to achieve this: def getUser(self): if not self.request.user.is_authenticated: ip = get_client_ip(self.request) if UserAccount.objects.filter(ip_address=ip).exists(): return UserAccount.objects.get(ip_address=ip) random_username = f"{randomString(10)}_guest" random_email = f"{randomString(5)}_guest@example.com" guest_user = UserAccount.objects.create( username=random_username, email=random_email, ip_address=ip, is_active=False, ) return guest_user else: return request.user And later, when this user submitted the registration form, I used the same function to retrieve this "guest" user and updated the rest of the model fields (email...) and set his password. Now, to return to the original question, how would I go about doing the same thing with the rest framework? I was also looking at the DRF documentation, and for authentication, you need … -
