我正在使用express和mongoose将我的表单数据保存到mongodb数据库中,但操作无法正常工作,因为它会给我一个错误,即我的模型未注册。我的代码:
index.ejs

<!DOCTYPE html>
<html>
<head>
    <title>Admin-Page</title>
</head>

<body>
<h1>admin-dashboard-interest</h1>
<form method="post" action="">
    <label for="select1">min select:</label>
    <select name="interest_active_user_min" id="select1">
        <option value="1">1</option>
        <option value="2">2</option>
    </select>

    <label for="select2">max select:</label>
    <select name="interest_active_user_max" id="select2">
        <option value="1">1</option>
        <option value="2">2</option>
    </select>
    <input type="submit">
</form>
</body>
</html>

schema.js

var InterestSchema = new Schema({
    settings: {
        admin_settings: {
            interest_settings: {
                interest_pending_user_settings: {
                        type: Number,
                        max: 100,
                        default: 0
                },

                interest_pending_user_value: {
                    type:[String]
                },

                interest_active_user:{
                    type:Number,
                    max:1000,
                    default:0
                },

                interest_active_user_max: {
                    type: Number,
                    max:1000,
                    default:100
                },

                interest_active_user_min: {
                    type: Number,
                    max:1000,
                    default: 5
                },

                active_interest: [{
                    name: {
                        type:[String],
                        unique:true
                    },
                    creator: {
                        type: mongoose.Schema.Types.ObjectId,
                        ref: 'User'
                    },
                    timestamp: {
                        type:Date,
                        default: Date.now
                    }
                }],

                pending_interest: [{
                    name: {
                        type:[String],
                        unique:true
                    },
                    creator: {
                        type: mongoose.Schema.Types.ObjectId,
                        ref: 'User'
                    },
                    timestamp: {
                        type:Date,
                        default: Date.now
                    }
                }],

                declined_interest: [{
                    name: {
                        type:[String],
                        unique:true
                    },
                    creator: {
                        type: mongoose.Schema.Types.ObjectId,
                        ref: 'User'
                    },
                    timestamp: {
                        type:Date,
                        default:Date.now
                    }
                }],

                removed_interest: [{
                    name: {
                        type:[String],
                        unique:true
                    },
                    creator: {
                        type: mongoose.Schema.Types.ObjectId,
                        ref: 'User'
                    },
                    timestamp: {
                        type:Date,
                        default: Date.now
                    }

                }]

            }
        }
    }
});
   var Int = mongoose.model('Interest', InterestSchema);

server.js

var mongoose = require('mongoose');
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;

var morgan = require('morgan');
var bodyParser = require('body-parser');

var uri = 'mongodb://localhost/interest';
var db = require('mongoose').connect(uri);

app.use(morgan('dev'));
app.use(bodyParser.urlencoded({
    extended: true
}));
app.set('view engine', 'ejs');

app.listen(port);

console.log('shit happens on port ' + port);

app.get('/', function(req,res){
   res.render('index.ejs');
});

app.post('/', function(req,res){
var content = new Int(req.body.content);
    content.save(function(err){
        if(err){
            return handleError(err);
        } else {
            console.log('your form has been saved');
        }
    })
});

require('./models/schema.js');

我得到一个错误“Int is not defined”,这是我用来注册mongoose模型的变量。我还要求在我的server.js中有mongoose文件,这样我就看不出哪里出错了。

在schema.js中替换

var Int = mongoose.model('Int', InterestSchema);

并在server.js中添加

var Int = mongoose.model('Int');

现在可以了。
schema.js中添加var mongoose = require('mongoose');
并且架构应该匹配。

在schema.js中,将最后一行更改为

exports.Int = mongoose.model('Interest', InterestSchema);

和server.js中(删除最后一行)

var Int = require('./schema);
