Redirect_to :back stops working after refreshing page in Rails 5.0

Question

我正在使用redirect_to :back转到ruby on rails项目中的上一页，但是当我刷新该页面后，它不再起作用了，我们如何保留存储在其中的上一页URL。

Answer 1

You can save your last page in session.

session[:return_to] ||= request.referer

And instead redirect_to :back , put this:

redirect_to session[:return_to]
