Creates a new Parameter_MedicationTypes node in a Neo4j graph database with the specified properties and returns the created node.

Purpose

This function is designed to insert a new Parameter_MedicationTypes node into a Neo4j graph database. It dynamically constructs a Cypher CREATE query based on the provided properties dictionary, executes the query using a run_query helper function, and returns the newly created node. This is useful for managing medication type parameters in a healthcare or pharmaceutical data model.

Source Code

def create_parameter_medicationtypes(properties):
    """Create a new Parameter_MedicationTypes node"""
    props_list = ', '.join([f"n.{prop} = ${prop}" for prop in properties.keys()])
    query = f"""
    CREATE (n:Parameter_MedicationTypes)
    SET {props_list}
    RETURN n
    """
    result = run_query(query, properties)
    return result[0] if result else None

Parameters

Parameter Details

properties: A dictionary containing key-value pairs representing the properties to be set on the new Parameter_MedicationTypes node. Keys should be valid property names (strings) and values can be any data type supported by Neo4j (strings, numbers, booleans, lists, etc.). Example: {'name': 'Antibiotics', 'category': 'Prescription', 'active': True}

Return Value

Returns the first node from the query result if the creation was successful, typically a dictionary-like object representing the created Parameter_MedicationTypes node with all its properties. Returns None if the query execution fails or returns no results. The exact return type depends on the implementation of the run_query function, but typically it would be a Neo4j Node object or a dictionary representation of the node.

Dependencies

• neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

from neo4j import GraphDatabase

# Assuming run_query is defined elsewhere
def run_query(query, params):
    driver = GraphDatabase.driver('bolt://localhost:7687', auth=('neo4j', 'password'))
    with driver.session() as session:
        result = session.run(query, params)
        return [record['n'] for record in result]
    driver.close()

# Create a new medication type parameter
properties = {
    'name': 'Antibiotics',
    'category': 'Prescription',
    'description': 'Medications that fight bacterial infections',
    'active': True
}

node = create_parameter_medicationtypes(properties)
if node:
    print(f'Created node: {node}')
else:
    print('Failed to create node')

Best Practices

• Ensure the properties dictionary contains only valid property names and values that are compatible with Neo4j data types
• Validate input properties before passing them to this function to prevent injection attacks or invalid data
• Handle the None return value appropriately in calling code to detect creation failures
• Consider adding error handling around the run_query call to catch database connection or query execution errors
• Be cautious with property names that might conflict with Cypher reserved keywords
• Ensure the run_query function properly sanitizes parameters to prevent Cypher injection attacks
• Consider adding uniqueness constraints on the Parameter_MedicationTypes label if duplicate nodes should be prevented
• Use transactions appropriately if this function is part of a larger operation that needs atomicity
