If I use selector.select to select a historic post by its timestamp & then try to create a new tagged relationship with the historic post it turns out that the historic post isn't actually tagged! However, a greyed-out circle containing the same information as the historic post appears in my graph & that ends up being tagged rather than the historic post... why is that & more importantly - how do I actually tag the historic post?
>>> import py2neo
>>> from py2neo import Graph, Node, Relationship
>>> from pandas import DataFrame
>>> graph = Graph(user='neo4j', password='notmypassword')
>>> t = Node("Tag", name="ANOTHER_TAG")
>>> graph.merge(t) # put the Tag into the graph
>>> selected = selector.select("Post", timestamp=1505826314)
>>> list(selected)
>>> [(deefe72:Post {date:"2017-09-19",id:"e0f08d21-afeb-49b7-b841-c6c366d11b62",text:"30 years in the building trade have injured my back & my joints",timestamp:1505826314,title:"building is bad for my back"})]
>>> rel=Relationship(t, "TAGGED", selected)
>>> graph.create(rel)
