Inline Panels and Model Clusters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ``django-modelcluster`` module allows for streamlined relation of extra models to a Wagtail page. For instance, you can create objects related through a ``ForeignKey`` relationship on the fly and save them to a draft revision of a ``Page`` object. Normally, your related objects "cluster" would need to be created beforehand (or asynchronously) before linking them to a Page.
The ``django-modelcluster`` module allows for streamlined relation of extra models to a Wagtail page via a ForeignKey-like relationship called ``ParentalKey``. Normally, your related objects "cluster" would need to be created beforehand (or asynchronously) before being linked to a Page; however, objects related to a Wagtail page via ``ParentalKey`` can be created on-the-fly and saved to a draft revision of a ``Page`` object.
Let's look at the example of adding related links to a :class:`~wagtail.core.models.Page`-derived model. We want to be able to add as many as we like, assign an order, and do all of this without leaving the page editing screen.
