Django viewset error: 'QuerySet' object has no attribute 'title'

Django Rest Framework - Serialize intermediate model fields (to POST or GET)
I am trying to handle POST and GET requests of my SalesProject model, which has a M2M field to CustomerInformation model, with an intermediate model of ProjectCustomer. I am wondering if there are any ways for me to be able to create a new SalesProject instance, and add the relevant instances of CustomerInformation to that created SalesProject instance, just like how it would have been done before I switched it to an intermediate model. Basically, this is the data that I would want to pass in for the POST request {sales_project_name: "Test Project", customer_information: [1, 2]} where [1,2] is the id of the CustomerInformation instance that I want to link M2M to that particular SalesProject I am creating Here is my models.py class CustomerInformation(models.Model): customer_id = models.AutoField(primary_key=True) customer_name = models.CharField(max_length=100) history = HistoricalRecords() class SalesProject(models.Model): sales_project_id = models.AutoField(primary_key=True) sales_project_name = models.CharField(max_length=100) customer_information = models.ManyToManyField('CustomerInformation', through='Project_Customer') history = HistoricalRecords() class Project_Customer(models.Model): project = models.ForeignKey('SalesProject', on_delete=models.SET_NULL, null=True) customer = models.ForeignKey('CustomerInformation', on_delete=models.SET_NULL, null=True) history = HistoricalRecords() I am new to using intermediate models, so do guide me along if I am mistakened about anything! From what I see, it seems like when I try to create a SalesProject using ModelViewsets, the customer_information field … -

SQL - Django Movie Booking System
I am currently working on movie booking site that allows user to book movie tickets at different time and date. I have already created the model for theater, seats, movie, and for movie date availability. I am wondering if; for every different time in a day: Example: - 12:30 PM - 3:00 PM - 5:30 PM It means for every theater in that 'time' i will create new seats for booking, just to get track on what seats are still available? Imagine, a theater-1 with capacity of 100 seats, that means that on 12:30 PM, a hundred seats are created. And at 3:00 PM, a different sets of seats are also created. That means that i will have a total of 200 seats, or 200 seats object on my database. Also the same scenarios on different dates, and theater number. Is there any way to reduce the number of data? Or my analyzation is wrong? -
Django aggregate Avg vs for loop with prefetch_related()
I have a Review model that is in one to one relationship with Rating model. A user can give a rating according to six different criteria -- cleanliness, communication, check_in, accuracy, location, and value -- which are defined as fields in the Rating model. class Rating(models.Model): cleanliness = models.PositiveIntegerField() communication = models.PositiveIntegerField() check_in = models.PositiveIntegerField() accuracy = models.PositiveIntegerField() location = models.PositiveIntegerField() value = models.PositiveIntegerField() class Review(models.Model): room = models.ForeignKey('room.Room', on_delete=models.SET_NULL, null=True) host = models.ForeignKey('user.User', on_delete=models.CASCADE, related_name='host_reviews') guest = models.ForeignKey('user.User', on_delete=models.CASCADE, related_name='guest_reviews') rating = models.OneToOneField('Rating', on_delete=models.SET_NULL, null=True) content = models.CharField(max_length=2000) I am thinking of a way to calculate the overall rating, which would be the average of average of each column in the Rating model. One way could be using Django's aggregate() function, and another option could be prefetching all reviews and looping through each review to manually calculate the overall rating. For example, for room in Room.objects.all() ratings_dict = Review.objects.filter(room=room)\ .aggregate(*[Avg(field) for field in ['rating__cleanliness', 'rating__communication', \ 'rating__check_in', 'rating__accuracy', 'rating__location', 'rating__value']]) ratings_sum = 0 for key in ratings_dict.keys(): ratings_sum += ratings_dict[key] if ratings_dict[key] else 0 Or, simply looping through, rooms = Room.objects.prefetch_related('review_set') for room in rooms: reviews = room.review_set.all() ratings = 0 for review in reviews: ratings += (review.rating.cleanliness + … -

Django: Reconstructing a form with ModelChoiceField from database
I have a Django form that contains several CharFields and ModelChoiceFields. Once the user has submitted the form, some calculations take place and the information is stored in the database. Since the form contains many fields, I would like to add the functionality that the user can reconstruct the form at a later point, change some settings and resubmit it. In my views.py, I check whether the form has been submitted before. If yes, I fill a dictionary with initial data from the database and then create an instance of the form. initialData = {} initialData['title'] = databaseObject.title ... ... form = myForm(initial = initialData) This works for the CharFields, but it does not work for the ModelChoiceFields. They are just empty. I cannot figure out how to put the queryset and the previously selected choice into the initialData dictionary so that the ModelChoiceFields are correctly populated and the correct choice is selected. -
Python, filter queryset and set equal to zero if empty

Are Django MySQL DB operations thread safe?
Background I am creating project where Django app must be integrated with some sort of IP cameras and other TCP/IP devices. (Either WEB api or low level Sock TCP/IP). There are some threads being run through WSGI or possibly being started with the user interaction. These threads collect data from given devices and then enqueue tasks to the Redis queue. In the queue data is being processed, there are some db requests made and model creation. I am using a MySQL database. I did not find any information here but possibly missed it. Problem Do I need to care about thread safety when I make requests to the DB ? (Basic model creation, Models filtering and searching), as they would access the same table and the same data? Right now all of the threads enqueue tasks to one queue. . I wanted to know if there will be problem when 2-6 threads are making requests or multiple queues instead of a one queue ? One queue in the beginning of the development process was fine but the task function starts to become unclear and hard to extend. I want to separate it thus separating one queue into multiple ones, and … -

Django unit test with payload value (and parameter in url)
I got following endpoint. I pass a token in my request payload: As you can see there is a bug in the data and I want to test this with unit tests to find the bug. My test: def test_create_firebase_token(self, fcm_mock): c = Client() token = "dummytoken" python_dict = {"1": {"user_pk": self.author.pk, "token": token}} c.post("/firebase", json.dumps(python_dict), content_type="application/json") as you can see the original url is "users/{user_id}/firebase" How can I test this endpoint correctly? Because the parameter in the url I'm confused.
