I have a mongoose schema with a providerData object:
... , providerData: {}, ...
and I would like to query for documents based on the IDs of objects in the providerData
object.
So I assumed I would have to use dot notation like so:
User.findOne({ providerIDString: providerID }, function(err, user) {...});
where
providerIDString is a string like 'providerData.facebook.id'
providerID is the providerData.facebook id
However the query keeps returning no results even though
db.users.find({"providerData.facebook.id":"THEFACEBOOKID"})
in the mongodb shell returns the correct document
Am I correct to assume this is happening because providerData.facebook
and providerData.facebook.id
are not defined in the User schema?
Does this mean I have to add them to the schema or is there a way to use dot notation on nested objects not in the mongoose schema?
I'm guessing that you have input like:
var providerIdString = 'providerData.facebook.id',
facebookId = "THEFACEBOOKID";
In which case you use:
var query = {};
query[provoderIdString] = facebookId;
Then:
db.users.find(query);
And behold! It works.
That is how you construct objects from variable names in JavaScript.
