使用Node查询MongoDb中的所有文档

Question

对于以下 GET请求，我试图让服务器返回所有＆＃34;音乐家＆＃34;文件，然后我将在音乐家 - 所有玉石模板页面上显示格式。

app.get("/musicians/all", function(req, res){
    var id = req.params.id;
    Musician.find(), function(err, data){
        if (err){
            res.render("error", {err: err});
        } else {
            console.log("here is the data: " + data);
            res.render("musicians-all", {
                musicians: data
            });

        }
    };
});

我的模型设置为 Mongoose ：

module.exports = function(mongoose){

    var Schema = mongoose.Schema;

    var MusicianSchema = new Schema({
        firstName: String,
        lastName: String,
        country: String,
        birthday: Date,
        instruments: [],
    });

    mongoose.model("Musician", MusicianSchema);

}

我已经设置了一个html表单和发布请求，可以正确提交数据。

app.post("/musicians/create", function(req, res){
    var firstName = req.body.firstName;
    var lastName = req.body.lastName;
    var country = req.body.country;
    var newMusician = new Musician;
    newMusician.firstName = firstName;
    newMusician.lastName = lastName;
    newMusician.country = country;
    newMusician.save(function(err, data){
        if (err){
            res.render("error", {err: err});
        }
        else {
            var id = data.id;
            res.redirect("/musicians/all");
            console.log(firstName + lastName + "from" + country); 
        }
    });
});

虽然我可以确认在提交html表单时将文档添加到MongoDb，但我不确定如何访问我要查找的文档。
