flash[:notice] 不适用于 redirect_to [英] flash[:notice] doesn't work with redirect_to

问题描述

我正在使用控制器状态:

 flash[:notice] = 'message'重定向到(控制器:'项目'，动作:'列表')

我不知道为什么通知没有出现.

我尝试并检查了很多东西:

1. flash.keep
2. flash.keep[:notice] = 'message'
3. flash[:notice] 与 render
配合良好
4. redirect_to(controller: 'item', action: 'list', notice: 'message')
5. flash.now[:notice] = "Hello world"
6. flash.now['foo'] = "Hello world" 带有 <%= flash['foo'] %> 在视图中
7. 布局中有一个 <%= flash[:notice] %>

我将以下代码放入布局中.当我的控制器方法有一个同名的视图时，flash[:notice] 工作正常.当我尝试访问另一个没有视图的控制器时会出现问题.

<% if !flash[:notice].blank?％＞<div class="通知"><%= flash[:notice]%>

<%结束%><% if !flash[:alert].blank?％＞<div class="alert"><%= flash[:alert]%>

<%结束%>

有人可以帮忙吗?

信息:

• Ruby (2.0.0)
• Rails (3.2.13)

解决方案

我不知道发生了什么.

我更新到 ruby​​ 2.0.0，它又开始工作了...

I'm using from controller status:

  flash[:notice] = 'message'
  redirect_to(controller: 'item', action: 'list')

I don't know why the notice don't show up.

I tried and checked many things:

1. flash.keep
2. flash.keep[:notice] = 'message'
3. flash[:notice] works fine with render
4. redirect_to(controller: 'item', action: 'list', notice: 'message')
5. flash.now[:notice] = "Hello world"
6. flash.now['foo'] = "Hello world" with <%= flash['foo'] %> in the view
7. There is a <%= flash[:notice] %> in the layout

I put the following code to in the layout. flash[:notice] work fine when I the controller method have a view with the same name. The problem happens when I try to reach another controller which don't have a view.

<% if !flash[:notice].blank? %>
    <div class="notice">
        <%= flash[:notice] %>
    </div>
<% end %>

<% if !flash[:alert].blank? %>
    <div class="alert">
        <%= flash[:alert] %>
    </div>
<% end %>   

Can anyone help?
