What's this?

load_target() public

Loads the target if needed and returns it.

This method is abstract in the sense that it relies on find_target, which is expected to be provided by descendants.

If the target is already loaded it is just returned. Thus, you can call load_target unconditionally to get the target.

ActiveRecord::RecordNotFound is rescued within the method, and it is not reraised. The proxy is reset and nil is the return value.
