環境ごとにfaviconを変える

More than 5 years have passed since last update.

開発環境と本番環境で favicon を変える

開発環境と本番環境をブラウザ上で間違って操作してしまった経験はありませんか?僕はあります。

僕もよくあります。。。(さっきもやっちまった)
設定したのでメモがてら。

application_helper.rb
def display_favicon
  if Rails.env.production?
    favicon_link_tag '/favicon.ico'
  else
    favicon_link_tag "/favicon-#{Rails.env}.ico"
  end
end
application.html.haml
%head= display_favicon

public配下に環境ごとのfaviconを置く。
一目で分かる色にしておくとよいですね。
