The 7Learnings code challenge is an opportunity to demonstrate proficiency in the problem solving skills we expect you to use at 7Learnings.

At 7Learnings, we use Python 3.12 as the main coding language. So it's strongly encouraged to create isolated Python environment using virtualenv to prepare yourself for the challenge.

First, create a python environment and install required packages:

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Include any additional dependencies you need in requirements.txt.

In this Django project, it already contains 2 Django models, dummy data and basic setup.

1. Category
2. Book

The first task is to migrate tags field (semicolon separated string) from existing Book model to seperated Django model. You're free to modify the Book model and decide fields in the new model.

The second task is implementation the following APIs (using Django Ninja):

1. List all Category
2. List all Tag
3. Create Book

We respect your time and don't want you spending more 3 hours on your challenge. We just want to get a sense of your thought process and development patterns. If there are features you don't have time to implement, feel free to use pseudo code to describe the intended behavior.

Your code will be reviewed by our engineers. The aspects of your code we will judge include:

• ability to get the technical environment set up
• completion of tasks
• code cleanness
• reasoning of the solution

Send us your final code, preferably as either one of the following:

• git-bundle: git bundle create my_changes.bundle origin/main..
• patches: git format-patch origin/main..
