[英]Is this possible to use migrations with bookshelf.js?
I am trying to use migrations with knex and bookshelf, and so far thats my code, it is an example from the bookshelf documentation: 我正在尝试使用knex和bookshelf进行迁移,到目前为止,这是我的代码,它是书架文档中的一个示例:
exports.up = function(knex, Promise) {
return knex.schema.createTable('books', function(table) {
table.increments('id').primary();
table.string('name');
}).createTable('summaries', function(table) {
table.increments('id').primary();
table.string('details');
table.integer('book_id').unique().references('books.id');
});
};
I tried run: 我试过跑:
knex migrate:make my_migration_name
knex migrate:latest
knex migrate:rollback
But not a single change in my database. 但我的数据库中没有一个变化。 Any ideas how I can get it working?
任何想法我怎么能让它工作?
Use .then()
to create a chain of promises: 使用
.then()
创建一个承诺链:
exports.up = function(knex, Promise) {
return knex.schema.createTable('books', function(table) {
table.increments('id').primary();
table.string('name');
}).then(function() {
return createTable('summaries', function(table) {
table.increments('id').primary();
table.string('details');
table.integer('book_id').unique().references('books.id');
});
});
};
