Purpose

This function queries a Neo4j database to fetch a specific intervention protocol flocks record identified by its UID. It's designed for retrieving individual records from the dbo_InterventionProtocolFlocks node type, commonly used in agricultural or livestock management systems where intervention protocols need to be tracked per flock. The function returns the first matching node or None if no match is found.

Source Code

def get_dbo_interventionprotocolflocks_by_uid(uid):
    """Get a dbo_InterventionProtocolFlocks node by its UID"""
    query = """
    MATCH (n:dbo_InterventionProtocolFlocks {UID: $uid})
    RETURN n
    """
    result = run_query(query, {"uid": uid})
    return result[0] if result else None

Parameters

Name Type Default Kind
uid - - positional_or_keyword

Parameter Details

uid: The unique identifier (UID) of the dbo_InterventionProtocolFlocks node to retrieve. Expected to be a string or numeric value that uniquely identifies a specific intervention protocol flock record in the Neo4j database. This value is used in an exact match query against the UID property of nodes.

Return Value

Returns a dictionary-like object representing the matched Neo4j node if found, containing all properties of the dbo_InterventionProtocolFlocks node. Returns None if no node with the specified UID exists. The node object typically includes properties such as intervention details, flock identifiers, and protocol information. The return type is either a Neo4j node object (dict-like) or None.

Dependencies

  • neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

# Assuming run_query function is defined and Neo4j connection is configured
from neo4j import GraphDatabase

# Example usage
uid_to_search = "IPF-12345"
result = get_dbo_interventionprotocolflocks_by_uid(uid_to_search)

if result:
    print(f"Found intervention protocol flock: {result}")
    # Access node properties
    # print(f"Protocol ID: {result['n']['protocol_id']}")
else:
    print(f"No intervention protocol flock found with UID: {uid_to_search}")

Best Practices

  • Ensure the run_query function is properly implemented with error handling and connection management
  • Validate the uid parameter before passing it to prevent injection attacks or invalid queries
  • Consider adding type hints to the function signature for better code documentation
  • Handle potential connection errors or database unavailability in production code
  • The function assumes run_query returns a list; ensure this contract is maintained
  • Consider adding logging for debugging purposes when nodes are not found
  • Ensure proper Neo4j driver cleanup and connection pooling in the run_query implementation
