Django: Use the different field for password in the Custom User Model
When you use the Custom User Model, you can change the "username" field using the USERNAME_FIELD = 'identifier' Is there a way to do similar thing for the "password" field? Something like PASSWORD_FIELD = 'my_password_field' If not, is there any was to store the password not in the default "password" field of the user model? No code tried because I don't know what to write in this case. Django docs contains the instruction about changing the changing the used identifier, but nothing about password. -

I need help properly implementing a booking scheduler and availability in Django
This question has been asked many times before on StackOverflow and in the Django forums, but none of the answers I've found are appropriate or complete enough for my situation. First, the brief: I'm creating a web application for a car rental business. In addition to helping them organize and centralize their fleet, it will also help them collect orders directly from customers. As with most rentals, the logistics of it all can be somewhat confusing. Someone may place an order for a car today (December 12th) but actually take the car over the Christmas to New Year's period. A renter may borrow a car for just two days, and then extend the booking at the last minute. When this happens (often very frequently), the business usually has to scramble to find another one for a different customer who was scheduled to get that car the next day. Adding to that, an individual car can only be rented to one client at a time, so it can't have multiple bookings for the same period. Most answers advocate for a simple approach that looks like this: models.py class Booking(models.Model): car = models.ForeignKey(Car, ...) start_date = models.dateField(...) end_date = models.dateField(...) is_available = … -

Error No URL to redirect to. Either provide a url or define a get_absolute_url method on the Model
i'm working on a django project to create football trainings. I'm testing the model and its saving.

Celery not retrying when an exception is raised when testing in Django
I have a class based celery task, which I would like to test by raising an error and then confirming that retry has been called. During the test, I want to raise a ConnectionError when msg.send() is called and then confirm that it is being 'retried'. The task essentially constructs an email using django.core.mail.EmailMultiAlternatives (which inherits EmailMessage) and then attempts to send that email. The task works well in practice, with a retry being called if a connection does not exist, my only problem is how to test it. So far, I have managed to raise the ConnectionError by patching EmailMultiAlternatives, however, the test does not trigger a retry in the celery terminal. tasks.py (Simplified) class SendMail(Task): max_retries = 4 base = 'BaseTask' def run(self, **kwargs): msg = EmailMultiAlternatives(kwargs.get('some_value'), etc.) msg.attach_alternative(rendered_html) try: msg.send(fail_silently=False) except ConnectionError as exc: self.retry(countdown=backoff(self.request.retries), exc=exc) test_task.py (simplified) class SendMailTest(TestCase): def setUp(self): self.message = {some data} def test_error(self): with patch.object(EmailMultiAlternatives, 'send', return_value=None) as mock_method: mock_method.side_effect = Exception(ConnectionError) SendMail(kwargs=self.message) My question is, why, when the test script is run and an exception is clearly being raise, does Celery not attempt to retry? -

Any way we can share a specific item publicly from a private S3 bucket?
The question is pretty vague but here's the entire problem statement. I am using Django REST APIs, and I'm generating invocies for my clients. Using wkhtmltopdf, I'm able to generate a PDF file which gets automatically backed up to S3. Now, we need to retreive the said invoice once our client clicks on a link. We're using pre-signed URLs right now, which last for 12 hours, right? Once that link expires, the entire backend fails. I mean, even if we go for permanent pre-signed links, would there not be a security issue? I could really use some guidance on this. -
