Railsは初めてで、Webサイトのスタートガイドに従っています。

$ rake db:migrate次のセクションで実行するとエラーが発生します：http： //guides.rubyonrails.org/getting_started.html#generated-a-model

セクションで初めて機能しました：http：//guides.rubyonrails.org/getting_started.html#running-a-migration

だから私は何が悪いのか分かりません。

私が走るとき$ rake db:migrate

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

private method `test' called for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x007f83a27503c8>

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

それで、私は--trace引数を使ってそれを実行するための指示に従いました。誰かがそれが何を意味するのか、そして問題は何であるかについての手がかりを持っているかどうか疑問に思いましたか？

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config

Tasks: TOP => db:migrate

生成される移行コードは次のとおりです。

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.string :commenter
      t.test :body
      t.references :post

      t.timestamps
    end
    add_index :comments, :post_id
  end
end

ジェネレーターを実行したときに、本文の「テキスト」ではなく「テスト」と言ったように見えます。

$ railsはモデルを生成しますコメントcommenter：string body：text post：references

Rakeはt.testのタイプを知りません...それはt.textだったでしょう
