Normally, Django foreign keys require both the parent and child records to be saved first; this package introduces ParentalKey and ParentalManyToManyField to hold related objects in memory until the parent is explicitly saved. This is useful for rendering previews of unsaved data, building draft model hierarchies, handling multi-step workflows, or constructing temporary object graphs for serialization or external systems.\n\nThe package extends ClusterableModel as the parent and uses ParentalKey in place of ForeignKey for one-to-many relations, and ParentalManyToManyField for many-to-many relations. Related objects are accessible via a subset of Django's QuerySet API (count, all, add) while in memory, and the entire cluster is persisted to the database in a single save() call. It also provides introspection functions to discover child relations on a model.","worth_installing":"Yes. django-modelcluster is actively maintained, has no known vulnerabilities, carries a permissive license, and solves a real Django limitation with low install friction. It is well-suited for any Django project that needs to work with unsaved model clusters or draft states. The only caveat is verifying that your specific ORM patterns (beyond basic QuerySet operations) are supported."},"id":"django-modelcluster","links":{"html":"https://skillfed.io/packages/django-modelcluster","md":"https://skillfed.io/packages/django-modelcluster.md","pypi":"https://pypi.org/project/django-modelcluster/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-01","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"django-modelcluster","python_support":"supports_current","summary":"Django extension to allow working with 'clusters' of models as a single unit, independently of the database"},"popularity":{"monthly_downloads":1007619,"position":4521,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"6.5"}
