pytrackunit 2.4.1

Easy access for TrackUnit REST API

TrackUnitPython

Python API for Trackunit

What is this package

This packages contains some usefull functions for an easy interface to TrackUnit's REST API. For information to the data see here.

Features:

• caches requests for faster access
• for timespan's bigger than 30 days it sufficiantly devides it into allowed requests
• asyncio functions availeble
• if data is cached it can process 12000 cached requests with 20 million data points in under 5 minutes.
• uses sqlite to cache data efficiently
• requests throttle function (Trackunit-API limits to 50 requests per second)
• provides stream-based generators for processing of big data

For more features write an issue here. Pull requests are welcome.

How to use

Install

Install the package via pip

pip install pytrackunit

Create a file in your execution directory with the name api.key which contains your TrackUnit API token. If that doesnt work for you, you can set the token in the constructor by calling tu = TrackUnit(api_key="<your key>").

Example

from pytrackunit.TrackUnit import TrackUnit

# Create the API
# It loads the key from api.key by default
tu = TrackUnit()
# alternatively
tu = TrackUnit(api_key="<api-key>")

# Get all vehicles from trackunit
# This is executing the 'Unit' request 
vehicles = tu.get_unitlist()

# Get history is executing 'Report/UnitHistory'
# Gets the history for the last 100 days
history = tu.get_history(vehicles[0]['id'],100)

# Get extended data 'Report/UnitExtendedInfo'
# Gets the history for the last 100 days
data = tu.get_candata(vehicles[0]['id'],100)

# Get faults 'Report/UnitActiveFaults'
# Gets the history for the last 100 days
data = tu.get_faults(vehicles[0]['id'],100)

# The library supports processing multiple vehicles too
# For memory intensive requests it supports preprocessing requests
# By default it prints a progress bar when using this function.
# Returns an iterator allowing processing big data
for x, _id in tu.get_multi_history( ['123456', '234567'] , 365):
    print(x, _id)

Example async

import asyncio
from pytrackunit.TrackUnit import TrackUnit

async def main():
    # Create the API
    # It loads the key from api.key by default
    tu = TrackUnit(use_async_generator=True)

    # Get all vehicles from trackunit
    # This is executing the 'Unit' request 
    vehicles = await tu.async_get_unitlist()

    # Get history is executing 'Report/UnitHistory'
    # Gets the history for the last 100 days
    history = await tu.async_get_history('123456',100)

    # Get extended data 'Report/UnitExtendedInfo'
    # Gets the history for the last 100 days
    data = await tu.async_get_candata('123456',100)

    # Get faults 'Report/UnitActiveFaults'
    # Gets the history for the last 100 days
    data = await tu.async_get_faults('123456',100)

    # The library supports processing multiple vehicles too
    # For memory intensive requests it supports preprocessing requests
    # By default it prints a progress bar when using this function.
    # Returns an iterator allowing processing big data
    # This is prefered if data gets bigger, because it only collects data when needed,
    # thus reducing needed memory
    async for x, _id in tu.get_multi_history( ['123456', '234567'] , 365):
        print(x, _id)
