sa.Column('deleted_at', sa.DateTime(), nullable=True, index=True)Timestamp columns like deleted_at and inserted_at lack indexes, which can degrade query performance.

Please add indexes to timestamp columns to improve query performance.

sa.PrimaryKeyConstraint('id'), sa.UniqueConstraint('project_id', 'user_id', name='uq_project_user')Consider adding a unique constraint on project_id and user_id in projectuser table to prevent duplicate associations

# This field requires an update mechanism, e.g., using SQLAlchemy events:
# from sqlalchemy import event
#
# @event.listens_for(Organization, 'before_update')
# def receive_before_update(mapper, connection, target):
# target.updated_at = datetime.utcnow() # Or datetime.now(timezone.utc)
updated_at: datetime = Field(default_factory=datetime.utcnow, nullable=False)The updated_at field is defined with default_factory=datetime.utcnow, which sets the timestamp only upon creation. To ensure this field accurately reflects the last modification time, an automatic update mechanism is needed. This typically involves using ORM event listeners (e.g., SQLAlchemy's before_update event) or database-level triggers. Without such a mechanism, the updated_at field will remain static after the initial insertion.

This error can be avoided (I think) by using the now function. See *_at factory methods in backend/app/models/document.py

This pull request introduces several enhancements to the
ai-platformrepository, primarily focusing on adding and updating timestamp fields across various database tables and models to improve data tracking and auditability. Key changes include:Database Schema Updates:
created_atwithinserted_atandupdated_atcolumns in thedocumenttable.CRUD Operations Enhancements:
Model and API Response Updates:
inserted_at,updated_at) and soft-delete fields (is_deleted,deleted_at) to theOrganizationandProjectmodels.OrganizationPublicandProjectPublicschemas to include new timestamp fields for API responses.Miscellaneous Improvements:
created_attoinserted_atin theproject_usermodel.Overall, these changes enhance the platform's data tracking capabilities and improve the separation of concerns in the codebase. However, some areas, such as error handling and security considerations for sensitive data, could benefit from further attention.
