title: Does Mongoose Actually Validate the Existence of An Object Id?
body: <p>I like the validation that comes with Mongoose. We are trying to figure out whether we want to use it, and put up with the overhead. Does anyone know if providing a reference to the parent collection when creating a mongoose schema, (in the child schema, specify the object id of the parent object as a field,) does this then mean that every time you try to save the document it checks the parent collection for the existence of the refereneced object id?</p>
