A convenience wrapper function that logs audit events specifically for review cycle operations by delegating to a generic log_event function with the resource_type pre-set to 'ReviewCycle'.

Purpose

This function provides a specialized interface for logging audit trail events related to review cycles in a document management system. It simplifies the logging process by automatically setting the resource type to 'ReviewCycle' and forwarding all parameters to the underlying log_event function. This is useful for tracking user actions on review cycles such as creation, updates, approvals, or deletions.

                   user: Union[DocUser, str],
                   review_uid: str,
                   details: Optional[Dict[str, Any]] = None) -> Optional[str]:
    """

    Args:
        event_type: Type of event from EVENT_TYPES
        user: User who performed the action or their UID
        review_uid: UID of review cycle
        details: Additional details about the event
        
    Returns:
        UID of the created audit event or None if creation failed
    """
    return log_event(
        event_type=event_type,
        user=user,
        resource_uid=review_uid,
        resource_type='ReviewCycle',
        details=details
    )

Parameters

Parameter Details

event_type: A string representing the type of event being logged. Should be one of the predefined values from EVENT_TYPES constant (not shown in code). Examples might include 'created', 'updated', 'approved', 'rejected', etc.

user: The user who performed the action. Can be either a DocUser object (a user model from the CDocs system) or a string representing the user's UID. This flexibility allows for logging events when you have either the full user object or just the identifier.

review_uid: A string containing the unique identifier (UID) of the review cycle being acted upon. This links the audit event to a specific review cycle resource in the system.

details: An optional dictionary containing additional contextual information about the event. Can include any relevant metadata such as changed fields, comments, timestamps, or other event-specific data. Defaults to None if not provided.

Return Value

Type: Optional[str]

Returns an Optional[str] which is either the UID (unique identifier) of the newly created audit event record as a string if the logging was successful, or None if the audit event creation failed for any reason (e.g., database error, validation failure).

Dependencies

• CDocs
• typing

Required Imports

from typing import Dict, Any, Optional, Union
from CDocs.models.user_extensions import DocUser

Usage Example

from CDocs.models.user_extensions import DocUser
from typing import Dict, Any

# Example 1: Log a review cycle creation event with a DocUser object
user = DocUser.get_by_uid('user_123')
event_uid = log_review_event(
    event_type='review_created',
    user=user,
    review_uid='review_456',
    details={'status': 'pending', 'reviewers': ['user_789', 'user_012']}
)
if event_uid:
    print(f'Event logged with UID: {event_uid}')

# Example 2: Log a review approval with just a user UID string
event_uid = log_review_event(
    event_type='review_approved',
    user='user_123',
    review_uid='review_456',
    details={'comment': 'Looks good', 'approved_at': '2024-01-15T10:30:00Z'}
)

# Example 3: Log a simple event without additional details
event_uid = log_review_event(
    event_type='review_viewed',
    user='user_123',
    review_uid='review_456'
)

Best Practices

• Always use valid event_type values from the EVENT_TYPES constant to ensure consistency across the audit trail
• Check the return value to verify that the event was successfully logged before proceeding with critical operations
• Include meaningful details in the details parameter to provide context for future audit reviews
• Use DocUser objects when available for richer audit information, but user UID strings are acceptable when the full object is not accessible
• Ensure the review_uid corresponds to an actual review cycle in the system to maintain referential integrity
• Consider wrapping calls in try-except blocks if audit logging failures should not interrupt the main application flow
• Use this function instead of calling log_event directly when logging review cycle events to maintain code consistency and readability
