🔍 Code Extractor

Validates whether a given status code exists in the DOCUMENT_STATUS_CONFIG configuration.

Purpose

This function serves as a validation utility to check if a provided document status code is recognized and valid according to the system's document status configuration. It's used to ensure that only valid status codes are used when setting or updating document statuses, preventing invalid state assignments and maintaining data integrity.

Source Code

def is_valid_document_status(status):
    """Check if status code is valid."""
    return status in DOCUMENT_STATUS_CONFIG

Parameters

Parameter Details

status: The status code to validate. Expected to be a value that can be compared against keys in DOCUMENT_STATUS_CONFIG (likely a string or enum value representing document states such as 'draft', 'published', 'archived', etc.). No type constraints are enforced in the function signature.

Return Value

Returns a boolean value: True if the status exists as a key in DOCUMENT_STATUS_CONFIG, False otherwise. This allows for simple conditional checks before applying status changes.

Usage Example

# Assuming DOCUMENT_STATUS_CONFIG is defined
DOCUMENT_STATUS_CONFIG = {
    'draft': {'label': 'Draft', 'color': 'gray'},
    'published': {'label': 'Published', 'color': 'green'},
    'archived': {'label': 'Archived', 'color': 'red'}
}

# Validate a status
if is_valid_document_status('published'):
    print('Status is valid')
else:
    print('Invalid status')

# Check invalid status
if not is_valid_document_status('invalid_status'):
    print('Cannot set invalid status')

Best Practices

• Always call this function before setting or updating document status to prevent invalid state assignments
• Ensure DOCUMENT_STATUS_CONFIG is properly initialized before using this function to avoid NameError
• Consider using this function in conjunction with error handling to provide meaningful feedback when invalid statuses are provided
• This function performs a simple membership test, so DOCUMENT_STATUS_CONFIG should be a dictionary or set for O(1) lookup performance
• Consider adding type hints to the function signature for better code documentation and IDE support
