Morphia - How to replace LongIdEntity.StoredId in last version?
StoredId class is just a POJO with 3 fields: id className (to store the type of object the auto-increment will be done on, but you could store something lese, this is just used to retrieve the adequate increment value, because you could have more than one auto-incremented collection !) value...
Why does mongoose model's hasOwnProperty return false when property does exist?
node.js,mongodb,mongoose,passport.js
It's because the document object you get back from mongoose doesn't access the properties directly. It uses the prototype chain hence hasOwnProperty returning false (I am simplifying this greatly). You can do one of two things: use toObject() to convert it to a plain object and then your checks will...

How to add new items to an array in MongoDB
$set is not an array update operation. The $set operator replaces the value of a field with the specified value. You just want to use $push by itself, as in .update({_id: id}, {$push: {name: item}}) You can't interpolate object property names in raw object declarations, so if you want to...
Incorrect response to mapReduce query in mongo-db
Your problem here is that you have missed one of the core concepts of how mapReduce works. The relevant documentation that explains this is found here: MongoDB can invoke the reduce function more than once for the same key. In this case, the previous output from the reduce function for...
Mongoose : update collection with previous data
First of all the schema you posted is off, should be { album : "album1", pictures: [ 1.jpg, 2.jpg, 3.jpg ] } note "pictures" is an array not an object.

Why the query scans 8x times the documents it finds - MongoDB
It's not "documents" it's "Objects" as is stated, but you would not be the first person to not fully understand the .explain() output. Put simply, you have as part of your index an "array" element (actually the maximum "two" allowed), which means that your index is what we call "MultiKey"....

c# mongodb driver groupby
I think the driver just doesn't implement the Linq GroupBy method. Use aggregate framework instead.

Hope it helps!...
Does MongoDB find() query return documents sorted by creation time?
No. Well, not exactly. A db.collection.find() will give you the documents in the order they appear in the datafiles host of the times, though this isn't guaranteed. Result Ordering Unless you specify the sort() method or use the $near operator, MongoDB does not guarantee the order of query results. As...
Do you get the same performance using index prefixes?
A "compound index" which is the correct term for your "link" does not create any performance problems on "read" ( since writing new entries is obviously more information ) than an index just on the single field used in the query. With one exception. If you use a "multi-Key" index...
What are some patterns I can look at for database implementations in JavaScript?
That's a pretty wide question, partly opinion based. This question should be closed, but I still want to give you some advice. There once was the Active Record pattern, which has been proven to be pretty difficult to maintain. The solution was the DAO pattern, but this adds a lot...

Why won't mgo unmarshall my struct properly?
The GetBSON method should return the value to be marshaled, not the binary data resulting from marshaling it. That's why its first result type is interface{} and not []byte.

How to overwrite object Id's in Mongo db while creating an App in Sails
Attention: Mongo id should be unique as possible in order to scale well. The default ObjectId is consist of a timestamp, machine ID, process ID and a random incrementing value.

Data not visible in mongoDB when inserted from PyMongo
Your code "works' but I think you may have copied-and-pasted something wrong. In particular, you're swapping the use of find() and find_one().

How to add a subdocument in a mongoose schema

DB relationship: implementing a conversation
It all depends on usage patterns. First, you normalize: 1 conversation has many messages, 1 message belongs to 1 conversation. That means you've got a 1-to-many (1:M) relationship between conversations and messages. In a 1:M relationship, the SQL standard is to assign the "1" as a foreign key to each...

MongoDB Java Driver 3.0 MapReduce
Yes, this is the expected behavior. Since the MapReduceIterable is a fluent interface, there must be some way to signal the driver that it's time to actually do the map-reduce, and currently the only way to do that is to start iterating. If you really don't need the results, and...

MongoJS - No Error On Unique Index

How to correctly update embedded object's field in mongodb?
The query needs to match on the _id (at least that is what it appears you are trying to match on). The update value for resetPasswordExpires is not a property of roles.
