Creating nodes and Realtionships in Neo4j Dynamically

Question

I have a Directory structure like below

C:\Users\Shiva\Desktop\Internship\shiva.txt

I want to Create nodes as each folder and I want a relationship between them.

Example Graph will be like this

C <-contains-> Users <-contains-> Shiva <-contains-> desktop <-contains-> 

Internship <-contains-> shiva.txt

I am going to pass the path in a dynamic way.

Answer 1

I imagine a solution could be to use Python's os.walk()

This function can be used as this:

from os import walk

def add_node(root, elem):
    query = 'MATCH (r: Directory {{name: "{0}"}})\
                CREATE (e: Directory {{name: "{1}")\
                CREATE (r)-[l: CONTAINS]->(e)\
                RETURN id(e), id(l)'.format(root, elem)
    # Run the query with your driver instance here

# Add the node for root here

for root, dirs, files in os.walk(your_dynamic_path, topdown = False):
    for dir in dirs:
        add_node(root, dir)
    for file in files:
        add_node(root, file)

With add_node(root, elem) being a function adding/merging the node elem to your Neo4J graph and adding the relation you want.
