rails flash.现在从部分开始

我有一个控制器，应该显示一个flash消息。没有显示flash消息。我唯一的问题是闪光信息没有显示。如果有人能对此给出一个解释，那就太棒了。我猜我的错误是微不足道的，但我不知道足够的解释发生了什么。

编辑:我为这一节添加了我的日志

编辑:当我点击无效信息的管理按钮时，什么都没有发生。当我刷新页面的flash消息显示。我真的只需要刷新当前页面，但它不工作。如果有人有任何想法，请分享。

编辑:我试过改变事情redirect_to @department, :notice => "invalid Password"

我仍然不能得到闪光消息显示。

编辑:从这个站点它说flash现在将显示在您正在渲染的视图中。但我渲染的视图是局部的。谁能至少让我知道我是否在正确的轨道上。除了我自己的想法之外，还有一点方向或想法吗?

这是我的关系的创建方法。

def create
    @department = Department.find(params[:manager_relationship][:department_id])
    if @department.authenticate(params[:manager_relationship][:password])
    current_user.manage!(@department)
    respond_to do |format|
        format.html { redirect_to @department }
        format.js
        end
    else
        redirect_to department_path@department, :alert => "Invalid Password"
    end
end

相同的代码在我的会话控制器中成功使用。

SessionsController
if user && user.authenticate(params[:session][:password])
        sign_in user
        redirect_back_or user
    else
        flash.now[:error] = 'Invalid email/password combination'
        render 'new'
    end

从局部

调用

部门/show.hmtl.erb

<% provide(:title, @department.department_name) %>
<div class="span8">
    <%= render 'manage_form' if signed_in? %>
</div>

_manage_form.html.erb

<div id="manage_form">
<% if current_user.managing?(@department) %>
<%= render 'unmanage' %>
<% else %>
<%= render 'manage' %>
<% end %>
</div>

_manage.html.erb

<%= form_for(current_user.manager_relationships.build(department_id: @department.id), remote: true) do |f| %>
    <div>
    <%= f.label :password %>
    <%= f.password_field :password %>
    </div>
    <div><%= f.hidden_field :department_id %></div>
    <%= f.submit "Manage department", class: "btn btn-large btn-primary" %>
<% end %>

application.html.erb

<!DOCTYPE html>
<html>
<head>
.
.
.
...
<body>
<%= render 'layouts/header' %>
<div class="container">
  <% flash.each do |key, value| %>
    <div class="alert alert-<%= key %>"><%= value %></div>
  <% end %>
  <%= yield %>
  <%= render 'layouts/footer' %>
</div>

这是一个unmanage和manage http请求的日志

首先，我无法在视图中看到你在哪里显示flash。您应该在希望显示消息的视图中执行如下操作:

<% if flash[:success] %>
  <p>
   <%= flash[:success] %>
  </p>
<% end %>
<% if flash[:error] %>
  <p>
   <%= flash[:error] %>
  </p>
<% end %>

第二，当你做重定向时，你应该使用flash[:success] = 'message'而不是flash.now[:success]。使用flash.now是您不重定向用户，而只是呈现视图。
