Ruby on Rails 開発でつまづいたところ

More than 3 years have passed since last update.

※開発初心者なので、情報に間違いなどあれば指摘してください。

トラブル:データベースの情報一覧ページ作成時にエラー

原因:

Allメソッドがきいていなかった

解決策:

→AllメソッドはActiveRecord::Baseに入っている
→使いたいモデルに対してクラス継承の必要あり
 具体的な手順は以下の2ステップ
1. ファイル作成:
/apps/model/(モデル名).rb

  1. 以下の文言を記入
class Post < ActiveRecord::Base
end

※なお、devise(gem)を用いた場合は自動でクラス継承用のファイルが作成される模様
