rails - 重新回到除非上一页是艺术家页面 [英] rails - redirect back unless previous page was artist page

问题描述

我想重新返回上一页，除非上一页是我的艺术家控制器的显示操作。

I'd like to redirect back to the previous page, UNLESS the previous page was my 'artist' controller's 'show' action.

看起来像：

if *previous page was artist show*
  redirect_to [track.artist, track]
else
  redirect_to :back
end

我的问题是 -

推荐答案

也许 request.referer 是您要找的？然后你可以这样说：

Perhaps request.referer is what you're looking for? Then you can say something like:

if request.referer == artist_url(track.artist)
  redirect_to [track.artist, track]
else
  redirect_to :back
end
