OBS。請原諒我的代碼，我的專案就像一個游樂場，我設定它只是為了學習。Sequelize 正在通過呼叫身份驗證連接到資料庫，但我的模型是“未定義的”，太傷心了......
我將展示一張圖片來展示我的專案結構。
我的索引和產品檔案是這樣的：
指數：
'use strict';
const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(__filename);
const env = process.env.NODE_ENV || 'development';
const config = require(__dirname '/../config/config.json')[env];
const db = {};
let sequelize;
if (config.use_env_variable) {
sequelize = new Sequelize(process.env[config.use_env_variable], config);
} else {
sequelize = new Sequelize(config.database, config.username, config.password, config);
}
fs
.readdirSync(__dirname)
.filter(file => {
return (file.indexOf('.') !== 0) && (file !== basename) && (file.slice(-3) === '.js');
})
.forEach(file => {
const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
db[model.name] = model;
});
Object.keys(db).forEach(modelName => {
if (db[modelName].associate) {
db[modelName].associate(db);
}
});
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
產品型號
'use strict';
const {
Model
} = require('sequelize');
module.exports = (sequelize, DataTypes) => {
class produto extends Model {
/**
* Helper method for defining associations.
* This method is not a part of Sequelize lifecycle.
* The `models/index` file will call this method automatically.
*/
static associate(models) {
// define association here
}
};
produto.init({
id: { type: DataTypes.NUMBER,
primaryKey: true},
titulo: DataTypes.STRING,
preco: DataTypes.NUMBER
}, {
sequelize,
modelName: 'produto',
});
return produto;
};
uj5u.com熱心網友回復：
你可以試試這個：
const Produto = require("../models/produto");
uj5u.com熱心網友回復：
這是小寫的產品，半天在這個......
const produto = require('../modelos');
因為它是重要的模型名稱......或類似的東西。
