Query a reference field to get the object Mongodb

Question

I need to access a full object by one of its refs:

• I have a User collection
• I have a UserType collection
• A User can have only one UserType
• A UserType has many Users
• I need to get all the Users from one UserType using Mongodb (by the UserType ID in User for example)

How can I do this ?

Thanks for all

Answer 1

You could fetch all USERS with particular UserTypeId use below query

db.user.find({"userType.id" : "<ID HERE>"});

Hope this could help you.
