dereference? about monk HOT 9 CLOSED

from monk.

We don't say that we support that api in the docs, I don't find db refs necessary really either imo.

from monk.

@travisjeffery Is there any convenient way to do one to many or many to many relations?

from monk.

@daimajia I'd do the same as this article: http://blog.markstarkman.com/blog/2011/09/15/mongodb-many-to-many-relationship-data-modeling/. Like it says in the article, you only need to use DBRef's in the array if your collection names change, in which case you could a write a migration anyway.

@travisjeffery I viewed this post before. How about one to many, for example:

db.person.insert({
  "_id": ObjectId("4e54ed9f48dc5922c0094a43"),
  "firstName": "Joe",
  "lastName": "Mongo",
  "groups": [
    ObjectId("4e54ed9f48dc5922c0094a42"),
    ObjectId("4e54ed9f48dc5922c0094a41")
  ]
});

How can i quikly get the instance of the ObjectId("4e54ed9f48dc5922c0094a42") and ObjectId("4e54ed9f48dc5922c0094a41") after I do find({_id: '4e54ed9f48dc5922c0094a43'}) method using monk?
another query?

from monk.

Yeah another query like so:

var person; // person you have above
db.groups.find({"_id": {"$in": person.groups }});

from monk.

@travisjeffery I'm new to mongodb. Thanks a lot for your help. I'll have a try. :-D

from monk.

@travisjeffery One more question. How can I bind the db.groups.find result with the person.groups column? Do it manually using underscore?

I implemented a middleware architecture and a dereferencing middleware here: https://github.com/monk-middlewares/monk-middleware-dereference
