如何在Django中遍历所有子对象？

Question

If many models in Django have foreign key relationship to a common model then how will it be possible to iterate over all the child models one by one.

I know about parent.child_set.all() , but I want to know if there is something that can be helpful to access child using a variable.

Answer 1

hard to tell what you're trying to do....but a simple getattr might help

child_var = 'child1'
qs = getattr(ParentModelInstance, child_var+'_set').all()
