Error "database couldn't be flushed" in pytest-django when adding live_server
When I run pytest with live_server, I see error: E django.core.management.base.CommandError: Database file:memorydb_default?mode=memory&cache=shared couldn't be flushed.

DRF serializer for questions that depend on multiple objects
I am trying to write a serializer which allows users to submit the answers to a quiz. However, the questions that should be answered depend on two separate things in the database. So, let's say we have these models:- class Day(models.Model): name = models.CharField() class Quiz(models.Model): name = models.CharField() class QuizQuestion(models.Model): quiz = models.ForeignKey(Quiz, related_name="questions") days = models.ManyToManyField(Day, related_name="questions") question = models.CharField() class QuizCompletion(models.Model): completed_by = models.ForeignKey(User) quiz = models.ForeignKey(Quiz) class QuizAnswer(models.Model): quizquestion = models.ForeignKey(QuizQuestion) quizcompletion = models.ForeignKey(related_name="answers", QuizCompletion) answer = models.CharField() So, to find the questions that the user has to answer for a particular quiz for a particular day, you'd need to do something like:- questions = quiz.questions.filter(days__id=day.id) I'm trying to create the serializer for submitting the answers to such a quiz so that it will check whether all of the questions have been answered. What is the best way to write this serializer? The days thing is the thing that's confusing me. Do I need a URL that includes BOTH the quiz ID and the day ID, so that I can get the right questions? class QuizCompletionSerializer(serializers.ModelSerializer): quiz = QuizSerializer() answers = QuizAnswerSerializer(many=True) class Meta: model = QuizCompletion fields = ["completed_by", "quiz", "answers"] def validate_answers(self, answers): # … -

Google file picker API giving error Javascript
I am trying to implement a google file picker in my Django Project. Currently when I try to create an HTML page with Google file picker integrated I am facing 500 Something went wrong error. This happens after I authorize my app and create access token.

Django 3.2 CITEXT and unique_together
I'm using Django 3.2 and postgreSql 12. I've added a new text field that should be case-insensitive, i.e if the value 'ab' exists, I want the DB to fail the request if someone is inserting 'Ab'. But this field shouldn't be unique all over the table, but unique with another field (unique_together). I've tried creating the field as 'CITEXT' and since it's deprecated in Django 4.2 I've used the Collation migration as recommended. The migrations passed, and when testing it I see that I can create two objects with the same letters, and different cases. Am I doing something wrong or this implementation of case-insensitive shouldn't work with 'unique_together'? The collation migration: operations = [ CreateCollation( "case_insensitive", provider="icu", locale="und-u-ks-level2-kn-true", deterministic=True, ), ] The model changes: class MyItem(models.Model): identifier = models.CharField(db_collation="case_insensitive", db_index=True, max_length=100, null=True) container = models.ForeignKey(Container, related_name='my_items', on_delete=models.CASCADE, null=True) class Meta: unique_together = ('identifier', 'container_id') After running the migrations, I've successfully created two MyItems with the same container and identifier='ab' and 'Ab' -
