  • Ticket #35241 – Description

    initial v3  
    33`Model._meta.get_parent_list()` computes the flattened list of ancestor models by MRO. This list is immutable, deterministic, and recursively constructed through the inheritance hierarchy. These properties make it a prime candidate for caching.
