veetility 0.4.8

Demo library

Getting Started

A library to help create python pipelines for processing Tracer Data

Full Online Documentation

This is primarily for working with Social Media Organic and Paid Advertisement Data but also contains generic functions for writing to postgreSQL and snowflake databases, creating notifications in Slack Channels and writing to Google Sheets

Library Installation

pip install veetility

To upgrade the library after an update

pip install veetility --upgrade

Initialisation of the UtilityFunctions class

An instance of the "UtilityFunctions" class can be initiated with the ability to read/write with google sheets and also to read/write to tables in a postgreSQL database. However none of these are mandatory.

Google Sheets Authentication

In order to use the functions that read/write from google sheets then a dictionary needs to be passed to the "gspread_auth_dict" argument. This dictionary can be obtained from a google API credentials JSON file.

The instructions for creating this JSON file can be found from the gspread documentation

Then copy the JSON information in curly brackets as a python dictionary into the gspread.service_account_from_dict() authentication method. The "client_email" parameter in the JSON material is the email address of the google sheet client we have created. This email address must be given read or write access to any google sheet you want to interact with.

PostgreSQL connection parameters

The following correction parameters need to be passed in during initialisation of the class instance

1. db_name e.g. "vayner_external_XXXXXXXXXXX"
2. db_host e.g. "dashboard-vayner-XXXXXXXXXXXXXXXXXXXX.rds.amazonaws.com"
3. db_port e.g. "5432" (this is the default for postgreSQL)
4. db_user e.g. "tom.jones"
5. db_password e.g. "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

Setup in code

It is advisable to put the parameters into a config.py file (cf) which can then be imported into the main script

import config as cf
from veetility import utility_functions

util = utility_functions.UtilityFunctions(cf.google_sheet_auth_dict,cf.db_user, 
                                          cf.db_password,cf.db_host,
                                          cf.db_port, cf.db_name)

Usage in code

Once an instance of the class UtilityFunctions has been created, e.g. "util" then functions (methods) of the class can be used e.g. "write_to_gsheet()".

This can write a pandas.DataFrame to any google sheet the "client_email" has been given "editor" access to. First pass in the name of the Google Sheet workbook, then the tab of the workbook, then the pandas.DataFrame

util.write_to_gsheet("Indeed Data Error Tracking","PaidNoBoostedMatch", 
                        paid_no_boosted_match)
