Django - how to get Table that is connected to User?
I have a built-in table from Django, "Users". Every user is getting stored in there. Now, I have created another table called "Questions" - Questions contains personal questions (fields) that every User on their own should answer. They are connected OneToOne: class Question(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) So far it's working. I can create a Question object and then assign it to a user. But: How can I query the fields of Question that is assigned to a user? In the end I want to have a big HTML form that contains all these questions the user can answer. I have tried following: questions = request.user.question.objects.get(user=user) context = {'questions':questions} That does not work and results in AttributeError: Manager isn't accessible via Question instances. I am stuck here and don't know how to do this. If anyone can help me, thank you. -

I have a django repository setup in gitlab and I am trying to automate build and deploy on google cloud using gitlab CI/CD.

Django - updating database with an excel file is causing an error when primary key already exists
Note in my model contact_email is my primary key for the Contact model I have an html page and form where users can upload an excel file to upload their contacts to the database.
