我正在尝试调试一种情况,根据用户输入表单字段的值,我似乎无法为对象创建新记录。现在我正忙于对象创建方面,其中帖子没有识别.create
。我是否也应该使用.create
或.build
?我试过两个,发生了同样的错误。
TypeError: Ann.create is not a function
at /Users/user/Desktop/Projects/node/nodeapp/app/controllers/appRoutes.js:13:20
appRoutes.js:
var express = require('express');
var appRoutes = express.Router();
var Annotation = require('../models/annotation-model');
appRoutes.route('/')
.get(function(req, res){
res.render('pages/activity-feed.hbs');
})
.post(function(req, res){
var annotation = new Annotation.create({
annotation_date: req.body.annotation-date,
}).then(function(user){
console.log(user.get({plain:true}))
});
annotation.save(function(err){
if (err)
res.send(err);
});
});
module.exports = appRoutes;
控制器索引(dbIndex.js):
var Sequelize = require('sequelize');
var sequelize = new Sequelize('test', 'admin', 'pwd', {
host:'localhost',
port:'3306',
dialect: 'mysql'
});
sequelize
.authenticate()
.then(function(err) {
if (!!err) {
console.log('Unable to connect to the database:', err)
} else {
console.log('Connection has been established successfully.')
}
});
var db = {}
db.Annotation = sequelize.import(__dirname + "/annotation-model");
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
注释-model.js:
module.exports = function(sequelize, DataTypes) {
var Annotation = sequelize.define('table', {
annotation_id: {
type: DataTypes.INTEGER,
primaryKey: true
},
annotation_date: DataTypes.DATE,
}, {
freezeTableName: true
});
return Annotation;
}
POST方法的表单(activity-feed.hbs):
<div class="row">
<div class="col-md-6 col-md-offset-3" style="background-color:#ffe680;">
<div class="annotation-form">
<img class="media-object" src="http://placehold.it/80x80" alt="Generic placeholder image">
<form action="/app" method="post">
<label for="annotation-date">Annotation Date:</label>
<br />
<button>Create</button>
</form>
</div>
</div>
</div>

您获得Ann.create is not a function
的原因是因为如果您遵循此结构,annotation-model.js:
没有正确的引用https://stackoverflow.com/a/33981210/880709一切都会好的,请参阅models/index.js
和routes/index.js
加上阅读here

这个问题的解决方案分为两部分。这两个部分都在appRoutes.js
文件中找到。
var models
应指向dbIndex.js
文件,而不是指定模型的位置(annotation-model.js
)。 var models = require('../models/dbIndex);
您必须在dbIndex
中指定对象,以便我们可以使用.create
方法。这意味着models.Annotation.create()
