.get()需要callback函数,但有一个

我正在和mongoose一起工作。

我在routes.js中编写了下面的代码

var docs = require('../app/controllers/genericController'); app.post('/newdoc', docs.createMainDoc); app.get('/listdoc', docs.listDocs); 

在genericController中:

 exports.listDoc = function(req, res) { var Model = mongoose.model(req.model); //i dont know, if this is defined or undefined. Actually i am not able to check it. Even if i comment whole body of this exports.listDoc, then also i get the same error. just assume here that here i am getting model. Model.find(function(err, models) { if (err) { res.render('error', { status: 500 }); } else { res.jsonp(models); } }); }; 

不,我得到的错误:

 .get() requires callback functions but got a [object Undefined] 

如何解决?
