Django not discovering models when moved into folder
My previous layout: project: app: models.py Right now it is like this: project: app: models: __init__.py model_name.py Because I have many more models now so I had to separate them.

What would be the most optimal/logical way to store answers to pre-determined yes or no questions to the database
I've been thinking: What would be the most optimal/logical way to store user answers to pre-determined 'yes or no' questions to the database. Note: the question model is in a one-to-one relationship with the user model. No. of Questions: 25 A: Store the questions as straight boolean variable/column to the database. Per user x 25 columns B: Store the questions as 'question' and boolean 'answer' to the database. Per user x 25 question rows, 1 user x 25 answer rows Which is faster? Please share your thoughts. -
