Question

I have tried using find and findOne and both are not returning a document. find is returning an empty array while findOne is returning null. err in both cases in null as well.

Here is my connection:

function connectToDB(){
    mongoose.connect("mongodb://localhost/test"); //i have also tried 127.0.0.1
    db = mongoose.connection;
    db.on("error", console.error.bind(console, "connection error:"));
    db.once("open", function callback(){
        console.log("CONNECTED");
    });
};

Here is my schema:

var fileSchema = mongoose.Schema({
    hash: String,
    type: String,
    extension: String,
    size: String,
    uploaded: {type:Date, default:(Date.now)},
    expires: {type:Date, default:(Date.now()+oneDay)}
});
var Model = mongoose.model("Model", fileSchema);

And my query is here:

Model.find({},function(err, file) {
    console.log(err)
    console.log(file);  
});

I can upload things to the database and see them via RockMongo but I cannot fetch them after. This my first time using MongoDB so I think I’m just missing some of the fundamentals. Any push in the right direction would be great!

The call to mongoose.model establishes the name of the collection the model is tied to, with the default being the pluralized, lower-cased model name. So with your code, that would be 'models'. To use the model with the files collection, change that line to:

var Model = mongoose.model("Model", fileSchema, "files");

or

var Model = mongoose.model("file", fileSchema);
