BE-Register Schools to Swim Meet

[MarisiaS]

This PR addresses issue #29

Implementation

1. backend/api/models.py

Added a Many-to-Many field to the SwimMeet model to establish a link between a swim meet and a list of schools.

2. backend/api/migrations/0011_swimmeet.py

Deleted existing migration and generated a new one by running the makemigrations command.

3. backend/api/serializers/MeetSchoolSerializer.py

• Created BasicSchoolSerializer based on ModelSerializer to display only the id and name of each school.
• Created MeetSchoolListSerializer based on ModelSerializer to display the id and name of a swim meet along with the list of schools related to the given swim meet.
• Created SchoolsListSerializer based on Serializer to display a list of IDs. This serializer validates the existence of a school for each ID in the list.

4. backend/api/views/MeetSchoolView.py

Created an APIView named MeetSchoolView with:

• get method to list the schools associated with a given swim meet. This view uses the MeetSchoolListSerializer.
• post method to associate a list of schools to a given swim meet. Uses the SchoolListSerializer.
• patch method to disassociate a list of schools to a given swim meet. Also uses the SchoolListSerializer.

5. backend/api/urls.py

Added the following endpoint:

• /meet_schools/<int:meet_id>/ uses MeetSchoolView.

Database

The following table was added because we added the ManytoMany field linking SwimMeet with School:

Swagger

All new endpoints are accessible through Swagger. Each endpoint has been tested successfully, including listing all schools associated with a swim meet, adding schools to a swim meet, and deleting schools from a swim meet.

When deleting schools from a meet through /api/meet_schools/{meet_id}/, it's allowing to leve the list without elements and returning a successful message, not sure if we need to add a validation for this case. At the end, no element is deleted which it's ok. What do you think?

I added allow_empty = False for the listField. The new message for empty lists is this one:
