My reference python code for Neo4j

When you can’t connect

Dear Reader,

I find when having those ‘why can’t i connect to Neo4j’ moments, having a reference code that you know works is rather useful.

Here’s my reference Python code for that situatin in case anyone finds it useful

There are two files, requirements.txt and the Python code, neo4jTest.py. These are given below. Save them both in the same folder.

The requirements file which will install the latest version of the Neo4j Python driver. Save as requirements.txt

Episode 3: Like what you’re done with that rabbit hole

Previously I wrote about the architectural pattern I was intending use for this adventure and I did make a start; honest.

I took initial steps to move communications into two functions, one for tfl and the other for Neo4j but…

Along came a squirrel.

Not a real one like that in the picture and really not this one ¹ but a virtual one wearing a large badge of distraction that read ‘I wonder if I could get all the information needed from tfl API in fewer calls?’

Episode 2: I am always willing to learn

In Epsode 1 I walked you through getting information from Tfl API ( transport for london ) and using that to start building a graph in Neo4j. Before we go much further in this endeavour, it’s time to look at how we’re approaching the architecture of this code and look at a couple ( there’s more I know ) of items that need looking at.

It is all about the REST

Neo4j DB as a Service ( DBaaS ) , Aura, now has a RESTful like API for provisioning. The full details of the API in long form are in the documentation; in short it’s a set of endpoints that provide for CRUD operations. You can try the Aura API from the documentation. Here we’re going to dig in and write code to do the needful.

Using Python and data from Tfl API

Episode 1 : Back to school

To become more familar with the TfL API and working with Neo4j programmatically , I’m going to write some funky Python code to explore and learn more about them. In Agile terms, it’s a Spike. The vast majority of this code is likely to be thrown away - no need to make it pretty , optimised or anything like that, just functional.
