rake db:migrate 什么都不做 [英] rake db:migrate does nothing

问题描述

我正在关注这个教程，我在运行 rake db:migrate

I'm following this tutorial, and I'm having a problem when running rake db:migrate

在 db/migrate 我有 create_post.rb 文件:

class CreatePosts < ActiveRecord::Migration
  def change
    create_table :posts do |t|
      t.string :title
      t.text :text
      t.timestamps
    end
  end
end

但它不会创建表.我的 database.yml 文件是:

But it does not create the table. My database.yml file is:

development:
 adapter: mysql2
 encoding: utf8
 database: blog_development
 pool: 5
 username: root
 password:
 socket: /tmp/mysql.sock

rake db:migrate 的输出似乎没问题.

The output from rake db:migrate seems ok.

我正在使用 phpMyAdmin 来处理我手动正确创建的数据库.

I'm using phpMyAdmin to handle the database, which is correctly created manually by me.

我做错了什么?
