Introduces a boolean field 'hidden' to the Activity model to
allow activities to be marked as hidden. This can be utilized
for filtering visible activities without deleting them from
the database.
Introduced initial database migrations for GPS logging and Mood tracking functionality, setting the foundation for data model structures in these modules. The migrations define essential entities such as GPSTrack, GPSToken, GPSPoint for the GPS logging module, and Mood, Activity, Aspect among others for the Mood tracking module. This pivotal change enables storing and managing user-generated GPS and mood data efficiently, paving the way for the implementation of core features related to GPS tracking and mood analysis. By removing 'migrations/' from .gitignore, we ensure future migrations are tracked and version-controlled, facilitating smoother database schema updates and deployments.
