Question

所以一切都在我的项目上工作到了这一点，即6.0添加第二个模型。我做了

rails generate model Comment commenter:string body:text article:references

这会生成我打开并查看的正确文件。 app/models/comment.rb 和迁移文件 _create_comments.rb（我遗漏了日期戳）

当我运行rake db:migrate时，我收到以下错误：

 == 20150709191058 CreateComments: migrating ===================================
-- create_table(:comments)
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

在处理这个项目时有没有人遇到过类似的错误我刚刚开始学习ruby和rails。

感谢您的帮助。

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.string :commenter
      t.test :body
      t.references :article, index: true

      t.timestamps null: false
    end
    add_foreign_key :comments, :articles
  end
end

我认为你在rails generate命令中键入了“test”而不是“text”。您可以删除所有新文件并重新开始，或将“t.test”更改为“t.text”。

`rake db：migrate`失败并带有NoMethodError
