Connecting to ne04j in Vagrant/Django

Drivers & Stacks

Newbie problem:

I'm trying to connect to NEO4J from Django/Vagrant and I keep getting a "ConnectionRefusedError: [Errno 111] Connection refused" when I try to run neomodel_install_labels.

in my settings file I've added:

from neomodel import config
import os

DATABASES = {
   'default': env.db('SNAP_DATABASE_URL'),
}

#Connect to Neo4j Database
config.DATABASE_URL = os.environ["NEO4J_BOLT_URL"]

NEOMODEL_SIGNALS = True
NEOMODEL_FORCE_TIMEZONE = False
NEOMODEL_ENCRYPTED_CONNECTION = False
NEOMODEL_MAX_CONNECTION_POOL_SIZE = 50

In my .env.vagrant file

NEO4J_USERNAME=neo4j 
NEO4J_PASSWORD=test
NEO4J_BOLT_URL="bolt://$NEO4J_USERNAME:$NEO4J_PASSWORD@localhost:7687"

In my model file:

from neomodel import (
    config,
    StringProperty,
    StructuredNode,
    RelationshipTo,
    RelationshipFrom,
    Relationship
)

import os

config.DATABASE_URL = os.environ["NEO4J_BOLT_URL"]

I receive the error when I try to install_labels.

vagrant@ubuntu-focal:/vagrant$ pipenv run neomodel_install_labels data_api.py  data_api/models/language.py --db bolt://neo4j:test@localhost:7687

It's been an awful long time since I've played with vagrant... Isn't there a special IP you have to use inside of Vagrant to refer to the host box's localhost?

Edit: maybe 10.0.2.2? Found this: https://stackoverflow.com/questions/23971373/is-it-possible-to-access-a-localhost-from-a-vagrant-devbox

Hello

Yes, a team member and myself both checked. It is working outside of Vagrant.

hi @MAR_DEV,

Have you checked to make sure that neo4j is listening on localhost at port 7687 and not a different port or network interface? netstat -an | grep -i listen | grep 7687 would be one way to check that
