Record rule based dynamic manipulations.
- depends on:
- django-dynamic-rules: an app that allows you to create dynamic rules
- related to a particular model. https://github.com/imtapps/django-dynamic-rules
When a dynamic rule is triggered, it can use a Dynamic Manipulation to create some other model (referred to as a side effect model). When the rules are run all of the side effect models will be deleted and re-created if necessary (as determined by the rule).
A manipulation log keeps track of the rule, side effect model, and the model that triggered the side effect. This is how we know what changes occurred as a result of the dynamic rule.
See the example app for a sample of what this might look in a shopping cart application. There are lettuce tests that clearly show a simplified shopping cart use case.
(run “./manage.py harvest -a sample -S” to run the lettuce tests)
