Utilities for deduping Django model instances
Project description
A collection of classes and utilities to aid in de-duping Django model instances.
Requirements
Python 3.6
Django 1.11
Install
pip install django-super-deduper
Usage
Merging Duplicate Instances
By default any empty values on the primary object will take the value from the duplicates. Additionally, any related one-to-one, one-to-many, and many-to-many related objects will be updated to reference the primary object.
> from django_super_deduper.merge import MergedModelInstance
> primary_object = Model.objects.create(attr_A=None, attr_B='')
> alias_object_1 = Model.objects.create(attr_A=X)
> alias_object_2 = Model.objects.create(attr_B=Y)
> merged_object = MergedModelInstance.create(primary_object, [alias_object_1, alias_object_2])
> merged_object.attr_A
X
> merged_object.attr_B
Y
Improvements
Support multiple merging strategies
Recursive merging of related one-to-one objects
Logging
This package does have some rudimentary logging for debugging purposes. Add this snippet to your Django logging settings to enable it:
LOGGING = {
'loggers': {
'django_super_deduper': {
'handlers': ['console'],
'level': 'DEBUG',
},
}
