• Transaction management with automatic rollback on errors
• Relationship creation and management
• Flexible node querying with AND/OR conditions
• Colored logging for better debugging
• Bulk node creation support
• Bidirectional relationship support
• Custom type validation

Installation

pip install neomate

Quick Start

from neomate import NeoMate, Types
from neo4j import GraphDatabase

# Define your model
class Person:
    __nodename__ = "Person"  # Optional: customize node type name
    
    name = Types(str, is_must_have=True)
    age = Types(int, default=0)
    hobbies = Types(list, is_must_have=False)

# Connect to Neo4j
uri = "neo4j://localhost:7687"
driver = GraphDatabase.driver(uri, auth=("neo4j", "password"))
session = driver.session()

# Initialize NeoMate
neo = NeoMate(session)

# Create a person
person = Person()
person.name = "Alex"
person.hobbies = ["programming", "music"]

# Save to database
neo.create_node(person)

# Query nodes
results = neo.get_node("Person", name="Alex")

Type Validation

The Types class supports:

• Basic Python types (str, int, list, etc.)
• Custom classes
• Optional fields with is_must_have=False
• Default values
• Bidirectional relationships

class User:
    name = Types(str, is_must_have=True)
    friend = Types("User", relate_name="FRIEND", bidiractional=True)

Transaction Management

All database operations are automatically wrapped in transactions:

# Automatic transaction management
neo.add_node("Person", name="John")

# Multiple nodes in single transaction
nodes = [
    {"name": "Alice", "age": 25},
    {"name": "Bob", "age": 30}
]
neo.add_nodes("Person", nodes)
