🔍 Code Extractor

Adds a comment to an approval cycle in a document management system, with optional resolution requirements and comment type specification.

Purpose

This function serves as a controller action to add comments to approval cycles within a controlled document workflow system. It enables users to provide feedback, request changes, or add general notes during the document approval process. The function supports different comment types and can flag comments that require resolution before approval can proceed. It delegates the actual comment creation to an underlying controller (_controller) and is decorated with logging functionality to track all comment additions.

Source Code

def add_approval_comment(user: DocUser, approval_uid: str, comment_text: str, 
                      requires_resolution: bool = False, 
                      comment_type: str = 'GENERAL') -> Optional[Dict[str, Any]]:
    """Add a comment to an approval cycle."""
    return _controller.add_comment(
        cycle_uid=approval_uid,
        user_uid=user.uid if user else None,
        text=comment_text,
        requires_resolution=requires_resolution,
        comment_type=comment_type
    )

Parameters

Parameter Details

user: A DocUser object representing the user adding the comment. Can be None, in which case the user_uid will be None. This is the authenticated user performing the action.

approval_uid: A string containing the unique identifier (UID) of the approval cycle to which the comment should be added. This references an existing ApprovalCycle in the system.

comment_text: A string containing the actual text content of the comment. This is the message or feedback the user wants to add to the approval cycle.

requires_resolution: A boolean flag (default: False) indicating whether this comment must be resolved before the approval can proceed. Set to True for comments that require action or response.

comment_type: A string (default: 'GENERAL') specifying the category or type of comment. Expected values likely include 'GENERAL', 'REVIEW', 'CHANGE_REQUEST', or other workflow-specific types defined in the system.

Return Value

Type: Optional[Dict[str, Any]]

Returns an Optional[Dict[str, Any]] containing the created comment data including comment ID, timestamp, user information, and comment details. Returns None if the comment creation fails or if there's an error. The dictionary typically includes keys like 'comment_uid', 'text', 'user_uid', 'created_at', 'requires_resolution', and 'comment_type'.

Required Imports

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

Usage Example

from CDocs.models.user_extensions import DocUser
from your_module import add_approval_comment

# Assume user and approval_uid are already obtained
user = DocUser.get_by_id('user_123')
approval_uid = 'approval_456'

# Add a general comment
result = add_approval_comment(
    user=user,
    approval_uid=approval_uid,
    comment_text='This section needs clarification on the methodology.',
    requires_resolution=False,
    comment_type='GENERAL'
)

if result:
    print(f"Comment added successfully: {result['comment_uid']}")
else:
    print("Failed to add comment")

# Add a comment requiring resolution
change_request = add_approval_comment(
    user=user,
    approval_uid=approval_uid,
    comment_text='Please update the compliance section before approval.',
    requires_resolution=True,
    comment_type='CHANGE_REQUEST'
)

if change_request:
    print(f"Change request added: {change_request['comment_uid']}")

Best Practices

• Always validate that the user has permission to add comments to the approval cycle before calling this function
• Ensure the approval_uid exists and is valid before attempting to add a comment
• Use requires_resolution=True for comments that need action or response to maintain workflow integrity
• Choose appropriate comment_type values to enable proper filtering and categorization of comments
• Handle None return values gracefully as they indicate failure to create the comment
• The function is decorated with log_controller_action, so all invocations are automatically logged for audit purposes
• Consider checking user permissions at a higher level since this function extracts user.uid which could fail if user is None
• Use this function within a transaction context if coordinating with other database operations
• Validate comment_text is not empty or excessively long before calling this function
