Title
Body
suppose I have the following datastructure: var user = {_id: 'foo', age: 35}; var post = {_id: '...', author: {$ref: user, $id: 'foo'},...}; How can I query all posts which references user[foo]? I tried the following but not work: db.post.find('author._id': 'foo'); var u = db.user.find({_id: 'foo'}); db.post.find('author': u); neither can I find the answer from the official document and google! Anyone has any idea?
