MySQL with Sequelize: ER_BAD_DB_ERROR: Unknown database

问题

I am following a tutorial and below is the code:

var Sequelize = require('sequelize')
var sequelize = new Sequelize('basic-mysql-database.mysql', 'root', 'password', {
    'dialect': 'mysql',
    'host': "localhost",
    "port": "3306"
});

var Todo = sequelize.define('todo', {
    description: {
        type: Sequelize.STRING
    },
    completed: {
        type: Sequelize.BOOLEAN

    }
})

sequelize.sync().then(function(){
    console.log('Everything is synced')

    Todo.create({
        description: 'Walking my dog',
        completed: false
    }).then(function (todo){
        console.log('Finished!')
        console.log(todo)
    })
});

I have installed MySQL. When I go into Settings > MySQL and it says MySQL Server instance is running

When I run node testDB.js I get the following error:

Unhandled rejection SequelizeConnectionError: ER_BAD_DB_ERROR: Unknown database 'basic-mysql-database.mysql'

I have never created any schema/table. I do have MySQL Workbench that I can create the schema and 'Todo' table with; however, I was under the impression that Sequelize does this on the fly? What am I doing wrong?

回答1:

There is a tiny little line in the setup that says:

The credentials for the respective database

Sync will create the tables for you, but it's not going to create the database.
