Initialize registry

data-transport uses a registry to store database authentication information and referenced by a human readable label.

The labels reference are recommended instead of having username,passwords ... hard coded
This makes sharing notebooks (Jupyter, Zeppelin, ...) without dissipating sensitive information, making this a solution to improve collaboration

Initialize Registry

The registry can be initialized through the command line (CLI) or in code.
A folder will be created in your home folder $HOME/.data-transport/transport-registry.json

Command line (CLI)

 
                    # creates folders and files needed
                    
$ transport registry reset < your email >

Create a file http-auth.json and it should contain the following

                    {
"provider":"http", 
                    
                    "url":"https://raw.githubusercontent.com/codeforamerica/ohana-api/master/data/sample-csv/addresses.csv"
                        
}

Add the created file http-auth.json to the registry under the label address-db

$ transport registry --add address-db http-auth.json

In code

import transport

import io

import json

#

# transport.registry.exists()                 

_email = 'steve@the-phi.com'

transport.registry.init(_email)

#

# Adding the entry to the registry now that is initialized

_authStr =  {"provider":"http",
"url":"https://raw.githubusercontent.com/codeforamerica/ohana-api/master/data/sample-csv/addresses.csv"
}

file = io.StringIO(json.dumps(_authStr))

transport.registry.set('address-db',file)
