Idiomatic use for exists? predicate

[Hussein B.]

Hi,

For a request such as:

/tree/:tree-id/leafs/:leaf-id

:exists? should check for tree-id, leaf-id or both?

Thanks for help.

You should check for both, I guess. However if the leaf-id alone gives your enough information you might only check for that. The URL would not make too much sense in this case and I'd mount the resource to /leafs/:leaf-id instead. If you validate the tree-id as a kind of authorization you might want to use the :authorized? decision to check whether the leaf-id matches the tree-id.

Clear. Thanks for your help.
