Set propertie to related nodes that are already created in Neo4j

Question

I'm using py2neo in Python to run my Cypher queries.
I'm trying to create Person nodes and relationships between then.
My DataFrame is like this:

df
>>> id_user      name                 follows.profiles
     a_123       Mc Marcão <3    [a_134, a_934, a_145, a_988]
     a_234       john                       a_111
     a_934       alice                       NaN
       :           :                          :
       :           :                          :

So here we can see that a Person can follows multiple persons, because follows.profiles is a list.

So this is what I did:

for index, row in df.iterrows():
    graph.run('''
    UNWIND $label3 as follow_profile
    MERGE (p1:Profile { id_user: $label1, name: $label2 })
    MERGE (p1)-[:FOLLOWS]->(p2:Profile { id_user: follow_profile })
    ''', parameters = {'label1': row['id_user'],
                       'label2': row['name'],
                       'label3': row['follows.profiles']
                      })

So the nodes are created and their relationships too. Now I want to set labels to the nodes relateds. How can I do this?

Answer 1

All the nodes you created already have a Profile label. But the neo4j Browser does not show the labels since normally you want identifying information to display for each node. However, the Browser does allow you to specify a different color for each label.

See the documentation for how to do that.
