Im still trying to make a social network with py2neo+flask+neo4j.
I've got a problem while searching my database with py2neo.I wanna find all the users that their username includes a special string.For example all the users that their username includes "dav".I wrote the code below and i dont know why i get this error...
from py2neo import Graph
graph=Graph("http://neo4j:123@localhost:7474/ ")
def search(name):
users=graph.merge("Person")
for N in users:
print N['username']
and this is my error:
Traceback (most recent call last): File "", line 1, in
File "/home/ali/Desktop/flask/search.py", line 10, in search users=graph.cypher.execute('match (p:Person) return p' File "/usr/local/lib/python2.7/dist-packages/py2neo/core.py", line 659, in cypher metadata = self.resource.metadata

Your URL is wrong, you should change it to this:
Graph("http://neo4j:123@localhost:7474/db/data")
Also, you can't execute cypher through the merge function, instead you should do this:
users = graph.cypher.execute('match (p:Person) return p')
