neo4j - Create multiple nodes and relationships with parameters -

i want create attachments email. have email info array following:

email: {name: 'auniquestring'} attachments: [ {label: 1, filename: 'a.jpg'}, {label: 2, filename: 'b.jpg'}, {label: 3, filename: 'c.jpg'}, ]

if had come in 1 attachment, should work:

match (n:email {name: "auniquestring"}) create (a:attachment {filename: 'a.jpg'}) create (n)-[r:attachment {label: '1'}]->(a)

how create attachment nodes @ 1 time , connect them email node (with single query)?

if pass them in parameters can do:

params:

{ email: {name: 'auniquestring'} attachments: [ {label: 1, filename: 'a.jpg'}, {label: 2, filename: 'b.jpg'}, {label: 3, filename: 'c.jpg'}, ]} create (n:email {name: {email}}) foreach (att in {attachments} | create (a:attachment {filename: att.filename}) create (n)-[:attachment {label: att.label}]->(a) )

foreach works on collections, see here:
