NEMO-transaction-validation 0.2.4

NEMO Plugin - Transaction Validation

This NEMO plugin is inspired from the transaction validation features implemented by Penn State's LEO.

Description

This plugin allows staff members to validate and contest transactions performed on behalf of a customer. Once contests are reviewed and approved by an administrator, the plugin automatically revises the transaction according to the contest submission. The plugin also saves a copy of the original transaction data as a contest item for historical data.

A transaction can be validated if no contests are required. Else, if contests have been submitted for approval, then it can be validated once all contests are approved by the administrator.

Installation

1. Install plugin.

pip install NEMO-transaction-validation

2. Add the plugin to INSTALLED_APPS in your settings.py file.

INSTALLED_APPS = [
    ...
    'NEMO_transaction_validation', #must be placed before 'NEMO'
    'NEMO',
    ...
]

3. Add the function auto_validate_transactions to the list of cron tasks. For this example, transactions at least five days old are checked and validated every 5 minutes.

sudo crontab -e

---> In the root crontab <---
...
*/5 * * * * /snap/bin/docker exec nemo django-admin auto_validate_transactions

N.B.: Ensure that there is a newline at the end of the crontab file
