我有一个控制器，它应该显示一条闪光消息。不显示闪烁消息。我唯一的问题是没有显示闪存消息。如果有人可以请对此做出解释，那将是很棒的。我猜我的错误是愚蠢的，但我不知道足以解释发生了什么。

编辑：我为此部分添加了我的日志

编辑：当我单击带有无效信息的管理按钮时，没有任何反应。当我刷新页面时，会显示 Flash 消息。我真的只需要刷新当前页面，但它不起作用。如果有人有任何想法，请分享。

编辑：我尝试将事情更改为 redirect_to @department, :notice => "invalid Password"

我仍然无法让 Flash 消息显示。

编辑：从这个站点它说现在闪存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走在正确的轨道上。除了我自己的一点方向或想法吗？

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

在我的会话控制器中成功使用了相同的代码。

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

它是从部分调用的

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 %>

应用程序.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>

这是取消管理和管理 http 请求的日志

首先，我在您的视图中看不到您在哪里显示闪光灯。您应该在要显示消息的视图中执行以下操作：

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

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

其次，当您进行重定向时，您应该使用flash[:success] = 'message'而不是flash.now[:success]. 用途flash.now是您不重定向用户，而只是渲染视图。
