Actually if you have sent something with redirect - you have passed it like GET params. In this case you can access them from your paramshash.
实际上，如果您通过重定向发送了一些东西 - 您已经像 GET params 一样传递了它。在这种情况下，您可以从params哈希中访问它们。
If you redirect like:
如果你像这样重定向：
redirect_to :controller => 'users', :action => 'edit', :id => 1, :param_a => 1, :param_b => 2
You have url like:
你有这样的网址：
http://localhost:3000/users/1/edit?param_a=1¶m_b=2
So you can access :param_aand :param_bin your view from params hash:
因此，您可以从 params 哈希访问:param_a和:param_b在您的视图中：
<%= params[:param_a] %>
<%= params[:param_b] %>
