Question

Code:

var connection = mongoose.createConnection('mongodb://localhost:9000/' + databaseName);
connection.db.dropDatabase(function(err){
    // never reach this point!
    debugger;
    console.log(err);
    console.log('-------------->Dropped database: ' + databaseName);
});

If I do connection.open it says that it’s already opening and no multiple calls to “open” are supported for the same connection.

Even this doesn’t work

var conn = mongoose.createConnection('mongodb://localhost',databaseName, 9000, {}, function(){
    console.log('created'); // is reached
    conn.db.dropDatabase(callback); // but the callback is not called anyway
});

What is the problem? (“mongoose”: “3.1.0”)
The database is not even dropped…
thanks

    var connection = mongoose.createConnection('mongodb://localhost:9000/' + databaseName, function(err){
        connection.db.dropDatabase(function(err){
                         // now it works!
                    })
    });

The problem is that the dropDatabase command was not queued and not run when the connection opened. So if I used a callback on the createConnection then it worked and drop the db after this, it worked!
