#246: Playlist update only introduce fields to change

[KristianLengyel]

Description

This pull request separates the song management logic into two new methods: one for adding songs and one for removing songs from playlists. Additionally, it refines the update_playlist method by renaming it to update_playlist_metadata to enable selective field updates, ensuring only specified fields (new_name, description, photo) are updated without requiring all fields to be sent.

Commit type

• feat: indicates the addition of new functionality for managing song additions/removals and updating playlist metadata selectively.

Issue

#246

Solution

The problem was resolved by implementing separate methods and endpoints for adding and removing songs from playlists, ensuring focused functionality. Additionally, the update_playlist method was renamed to update_playlist_metadata, now only requiring fields that need updating. This change allows the frontend to update playlist details more efficiently, reducing redundant data handling.

Proposed Changes

• Create add_songs_to_playlist method to add songs to a playlist.
• Create remove_songs_from_playlist method to remove songs from a playlist.
• Rename update_playlist to update_playlist_metadata, enabling updates to only specified fields (new_name, description, photo).
• Add endpoints in the controller for new song management functions.
• Update and add test cases for new methods and adjusted update_playlist_metadata functionality.

Potential Impact

These changes streamline data transfer by minimizing the fields required for updates and isolating song management. However, any existing calls to the previous update_playlist method may need adjustment to align with the renamed method and modified endpoint behavior.

Screenshots

(No screenshots needed for backend changes)

Additional Tasks

• Update any associated documentation with the new method and endpoint details.
• Ensure that all test cases are passing and that test coverage is adequate.
