});

// the schema is useless so far
// we need to create a model using it
var forms = mongoose.model('form', formSchema);

// make this available to our Node applications
module.exports = forms;

我正在使用mongodb和mongoose运行rest API，我已对app.js进行了所有相关更改，但仍然无法在node.js中运行mongodb的任何功能。我已经附加了app.js和路由器文件，它是使用此查询的路由器形式。

Answer 1

好的，是的，如果＆＃34;形式＆＃34;是你的猫鼬模型，然后正确的语法是forms.create（....）与小写c。

*更新* 好的，根据您的评论，我仍然不确定您的应用结构;事情让你感到困惑。

在任何情况下，你想要在你的路由器中拥有的是mongoose产生的模型。你可以这样做：

var Form = mongoose.model('form'); // note that this assumes you've already called require on your ./models/forms.js file to run it and get the schema into mongoose

formRouter.route('/')
.post(function(req,res,next){
   Form.create(/* your args here and callback and stuff */);
});
