Get nth parent in DJANGO -
i have models this:
a->b->c->d b parent of a, c parent of b...
i have a object database. best way related d object a object?
to retrieve instance of d instance of a:
d_instance = a_instance.b.c.d where a_instance instance of class a.
whether "best way" question; depends on mean "best". performance-wise depends on how data structured.
remember join effected each time entity (or parent) accessed using dot notation shown above.
