【Refile】attachment_image_tag の書き方

Last updated at Posted at 2021-03-22

attachment_image_tagの書き方

<%= attachment_image_tag 保存先インスタンス名, :保存先カラム名, :fill, 幅, 高さ, format:'拡張子', fallback:"代替画像" %>

例えば、
<%= attachment_image_tag post_image.user, :profile_image, :fill, 100, 100, format:'jpg', fallback:"no_image.jpg"

*fillでうまく表示されない場合は、sizeでサイズを指定
:fill, 幅, 高さsize: "幅x高さ"
