When using a Mongoose model, if you have a reference to a queried document, you’ll notice that you cannot call hasOwnProperty() to check if it has a certain property. For example, if you have a User model, and the schema has a property called “verified”, if you call user.hasOwnProperty(‘verified’), it will not return true!
This is because the object you get back from your mongoose query doesn’t access properties directly.
An easy and quick workaround is like so:
var userObject = user.toObject(); if(userObject.hasOwnProperty('verified')) //...
And now hasOwnProperty() will return true.
