Filter by ObjectIds

[kersten]

Hello,

I have a collection where the documents are matched against a user_id. So my document looks something like this:

{
    "duration": "00:20",
    "name": "Samplename",
    "user_id": { "$oid" : "51d299b48e8ab7da3a000003" },
    "__v": 0,
    "_id": { "$oid" : "51d29c79579343a63b000003" }
}

Is there an easy way of just fetching documents where the user_id matches when I GET the documents? Filter doesn't work because you are using a RegEx which will not work with ObjectId fields.

Creating a finder is the easiest way

Ok, got that. But how would you implement security? You write that it should be a good place to use a transformer, but how would I get the currently logged in user? I cannot get the session object, or do I miss something?

You can use a filter and capture the user. Due to nodes threading model you can do things you wouldn't do in other frameworks. I use passport for general security it works fine. For more granular security transformers and filters should work.

How can you use transformers for security? Surely all the user needs to do to circumvent it is make a request and strip any transformers or filters?

well, you can override the transformers in the route preventing someone from just injecting transformers in there. req.get('/rest/api/*', function(req, res, next){

req.query.transformers = ['yourselecurity transformer']; next(); });
