Sequelize不创建多对多连接表

Question

当我启动我的服务器时,在建立数据库连接后不久,我这样做:

var tool = require("./tool"); //created with Sequelize.define()
var requirement = require("./requirement"); //created with Sequelize.define()

tool.belongsToMany(requirement, {through: "toolRequirements"});
requirement.belongsToMany(tool, {through: "toolRequirements"});

tool.sync();
requirement.sync();

我希望看到正在创建连接表,但它不存在.我错过了什么？

Executing (default): CREATE TABLE IF NOT EXISTS `requirements` (`id` INTEGER PRIMARY KEY AUTOINCREMENT, `name` VARCHAR(255) NOT NULL, `createdAt` DATETIME NOT NULL, `updatedAt` DATETIME NOT NULL);
Executing (default): CREATE TABLE IF NOT EXISTS `tools` (`id` INTEGER PRIMARY KEY AUTOINCREMENT, `name` VARCHAR(255) NOT NULL, `idCode` VARCHAR(255), `createdAt` DATETIME NOT NULL, `updatedAt` DATETIME NOT NULL);
Executing (default): PRAGMA INDEX_LIST(`requirements`)
Executing (default): PRAGMA INDEX_LIST(`tools`)

它在文档中说该表是为我创建的.我不应该自己手动创建一个.

我在用:

• Sequelize v3.23
• SQLite 3

似乎不是呼唤.sync()每一个模型,我应该只调用sequelize.sync()一次.

这样做:

var tool = require("./tool"); //created with Sequelize.define()
var requirement = require("./requirement"); //created with Sequelize.define()

tool.belongsToMany(requirement, {through: "toolRequirements"});
requirement.belongsToMany(tool, {through: "toolRequirements"});

sequelize.sync();

//DO NOT tool.sync();
//DO NOT requirement.sync();

以下是我在项目中使用它的示例:link
