【Rails】deviseを使ったサインアップ機能 wrong number of arguments (given 0, expected 1)というエラー

Posted at

エラー詳細

deviseを導入して、サインアップを実行したところ、このような内容のエラーが吐かれた。

ArgumentError (wrong number of arguments (given 0, expected 1)):
wrong number of arguments (given 0, expected 1)

#解決法

user.rb
has_secure_password

を消す。
has_secure_passwordとは、パスワードをDBに保存する時に、暗号化して保存してくれるrailsの機能のこと。deviseを使う場合は不要なので、コメントアウトしておきましょう。
