Mongoose: querying against ObjectIds with the $lt and $gt operators
Assuming a Schema with a normal _id property, I want to query with a $gt operator. Equivalent MongoDB query:
db.applications.find({ _id : { $gt : ObjectId("53ddb3c00000000000000000") } })
But, on the mongoose side, when using an object with the ObjectId type, it throws:
var minimumObjectId = new mongoose.Schema.ObjectId(minimumObjectIdString);
Applcation.find({ _id : { $gt : minimumObjectId } })
/*
{ [CastError: Cast to ObjectId failed for value "ObjectId('53de7ea3000000000000000')" at path "_id"]
message: 'Cast to ObjectId failed for value "ObjectId(\'53de7ea3000000000000000\')" at path "_id"',
name: 'CastError',
type: 'ObjectId',
value: 'ObjectId(\'53de7ea3000000000000000\')',
path: '_id' }
*/
As does a simple String:
Application.find({ _id : { $gt : minimumObjectIdString } })
I've even tried something crazy like:
Application.find({ _id : { $gt : "ObjectId('" + minimumObjectIdString + "')" } })

@vkarpov15 , I think this may also be a problem in the underlying mongo-native-driver, as I tried to do something like:
Application.collection.find({ _id : { $gt : "53f0c1850000000000000000" } }, function(err, cursor) {
console.log(err)
cursor.toArray(function(results){
console.log(results);
})
})
What are you doing to get minimumObjectIdString? You should use mongoose.Types.ObjectId instead of mongoose.Schema.ObjectId
var minimumObjectId = new mongoose.Types.ObjectId(minimumObjectIdString);
Applcation.find({ _id : { $gt : minimumObjectId } })
It should work with a string as well.
