BE- Athlete model, serializer and view

[viriponce]

This PR addresses issue #21

Implementation

1. backend/api/models.py Implemented the Athlete model with the following fields:

• first_name = models.CharField (max_length=150, blank=False, db_collation="case_insensitive")
• last_name = models.CharField(max_length=150, blank=False, db_collation="case_insensitive")
• date_of_birth = models.DateField()
• gender = models.CharField(max_length=20, choices=Gender.choices)
• status = models.CharField(max_length=20, choices=Status.choices)
• session = models.ForeignKey(Session, on_delete=models.SET_NULL, null=True, related_name='atlethe_session_group')
• school = models.ForeignKey(School, on_delete=models.CASCADE, related_name='atlethe_school_group')
• email = models.EmailField(blank=True, null=True)
• notes = models.TextField(blank=True, null=True)

2. backend/api/migrations/0011_athlete.py After creating the model, I ran the makemigrations command and the migration for the Athlete model was created.

3. backend/api/serializers/AthleteSerializer.py Created a Model serializer for the Athlete model. Included all the fields. Add a validation method for date_of_birth to check the date is not in the future.

4. backend/api/views/AthleteView.py Created a basic Model View set for Athlete.

5. backend/api/urls.py Added a router to generate the endpoints for Athlete.

6. backend/api/fixtures/setup_data.json

Added data for 6 Athlete objects.

I applied the migration with migrate command, then loaded the fixture data with loaddata command.

Swagger

The endpoints are accessible through Swagger:

I tried each of the new endpoints successfully. I was able to create, delete, patch and get an athlete. When posting and patching, I got the expected error for entering invalid data.
