Changes:
- Removed server_default with CURRENT_TIMESTAMP from User model (SQLite doesn't support non-constant defaults in ALTER TABLE)
- Updated migrations 002 and 003 to add datetime columns without server defaults
- Added manual timestamp updates using SQLite's datetime('now') function in migrations
- Modified User model to handle timestamps in Python code instead of database defaults
- Updated profile routes to manually set updated_at timestamps on profile changes
- Enhanced User model __init__ to set default timestamps for new users
This resolves the 'Cannot add a column with non-constant default' SQLite error
while maintaining proper timestamp functionality.
Changes:
- Enhanced migration 002 with column existence checks to prevent duplicate column errors
- Added comprehensive migration 003 that syncs database with current model state
- Modified application startup to avoid conflicts between create_all() and Alembic
- Added proper table/column existence checking in migrations
- Improved migration safety for production environments
- Removed automatic table creation when database already exists (relies on migrations)
This resolves the 'duplicate column name' error by ensuring migrations
check for existing columns before attempting to add them.
