9 years ago By using Animal.hasOne('owner', Person), you are creating the owner_id in the animal table as you said.
This means that each 'owner' can have many animals.
Using something like personInstance.getAnimals() should return the animals for the owner.
You have a one-to-many relationship as that Person has many Animals, and Animal hasOne Person.
Is it possible to add Associations (hasOne) in mongoDb using orm module. In your examples only used mysql, postgresql only, I think that it is not possible with mongodb. But i am bit confused that anywhere in the document not mentioned about mongo db relation.
Please tell me, how to achieve one to many relation .
var Person = db.define('person', { name : String }); var Animal = db.define('animal', { name : String }); Animal.hasOne("owner", Person); // creates column 'owner_id' in 'animal' table if it is possible ,please explain it with model.create()
otherwise please explain how to achieve this with mongodb as database.
Please help me it is very urgent.....
