迭代mongoose.models

Question

我正在尝试获取所有mongoose模型名称并在视图中迭代它们（test.jade）

路线

router.get('/dashboard', ensureAuthenticated, function (req, res) {
     var models = mongoose.models;
     console.log(models); 
     res.render('test',{data:models});
})

我在节点控制台上获得了这个日志：

{ User: 
   { [Function: model]
     base: 
      { connections: [Object],
        plugins: [],
        models: [Circular],
        modelSchemas: [Object],
        options: [Object] },
     modelName: 'User',
     model: [Function: model],
     db: 
      { base: [Object],
        collections: [Object],
        models: [Circular],
        replica: false,
        hosts: null,
        host: 'localhost',
        port: 27017,
        user: '',
        pass: '',

        otherDbs: [],

        _closeCalled: false,

        db: [Object] },

     schema: 
      { paths: [Object],
        subpaths: {},
        virtuals: [Object],
        nested: {},
        inherits: {},
        callQueue: [],
        _indexes: [],
        methods: {},
        statics: {},
        tree: [Object],
        _requiredpaths: [],

        queue: [],
        buffer: false } },

查看

for(var prop in data)
   p #{prop}: #{data[prop]}

问题是我在视图

的迭代操作后无法获得任何结果

Answer 1

在你的路线中，试试这个：

router.get('/dashboard', ensureAuthenticated, function (req, res) {
     var models = Object.keys(mongoose.models);
     var schemas = mongoose.modelSchemas;
     res.render('test',{models: models, schemas: schemas});
})

然后在你的布局文件中试试这个（假设你正在使用玉）

each model in models
    p #{model} : 
        each path in schemas[model].paths
            div #{JSON.stringify(path)}

Answer 2

很难说，但看起来您可能正在记录构建模型的函数，而不是模型数据的实例。
