Explain with highlit
Nested routers create hierarchical URL structures for related resources. I use drf-nested-routers to define parent-child relationships in URLs like /posts/1/comments/. This makes APIs more RESTful and intuitive. I filter child resources by parent ID in viewsets. For deep nesting, I limit to 2-3 levels for simplicity. Nested routes make relationships explicit in URLs. I use parent_lookup_kwargs to extract parent IDs. This pattern works well for one-to-many and many-to-many relationships.
