How do I perform a query in Mongoose?

Question

> db.users.findOne();
{
    \"_id\" : ObjectId(\"4db8ebb4c693ec0363000001\"),
    \"fb\" : {
        \"name\" : {
            \"last\" : \"Sss\",
            \"fi         


        

Answer 1

Try this :

User.findOne( { $where : "this.fb.gender == 'male' " } )

or

User.findOne( { fb.gender : "male" } )

Answer 2

I'm one of the authors of mongoose. You can do this query in one of several ways:

• find syntax

  User.findOne({'fb.gender': 'male'}, callback);
  

• where syntax

  User.where('fb.gender', 'male').findOne(callback);
  

• named scope syntax

  UserSchema.namedscope('male').where('fb.gender', 'male');
  // ...
  var User = mongoose.model('User', UserSchema);
  
  // Now you can write queries even more succinctly and idiomatically
  User.male.findOne(callback);
