BE-Registering sites

[MarisiaS]

This PR addresses issue #14

Implementation

1. backend/api/models.py Create Site model with the following fields:

• Name (Unique and case-insensitive constraints were added after the initial migrations)
• Num_lanes
• Pool_name
• Len_unit (Added a sub-class to manage choices for Len_unit)

Added a sub clase to manage the choices for Len_unit

2. backend/api/migrations/0004_site.py Initial migration to create the Site model. Note: In this migration, the Name field does not have Unique and case-insensitive characteristics.

3. backend/api/migrations/0005_add_collation_unique_to_name_site.py In this migration, Unique and case-insensitive characteristics were manually added to the Name field.

4. backend/api/serializers/SiteSerializer.py Created a generic serializer with Site as the model.

5. backend/api/views/SiteView.py Created a view for Site with:

• Ordering by name
• Search by name
• Sorting by name

6. backend/api/urls.py Added a router to generate the endpoints.

7. backend/api/fixtures/setup_data.json

Added data for the example site.

Swagger

The endpoints are accessible through Swagger:

After executing the migrations and loading the setup file, the example site is visible:

I successfully performed operations such as creating new sites, deleting them, listing them, and utilizing the sort and search functions.
