Question

我无法在模板中显示notice变量。代码如下：

class UserController < ApplicationController
  protect_from_forgery
  skip_before_filter :require_login, :except=>[:list,:add,:delete,:update]
  def add
  end

  def delete
  end

  def update
  end

  def list
  end

  def login
  end

  def logout
  end

  def isloggedin
    login = params[:login].to_s
    password = params[:password].to_s
    logged_in = User.where(:user_name => login,:password => password).limit(1)
    if not logged_in.blank?
      session[:userinfo] = logged_in
      redirect_to '/event/list'
    else

      flash[:notice] = 'Unable to login'
      redirect_to '/user/login'
    end

  end
end

模板文件

<div><%= notice %></div>

Answer 1

将其添加到模板文件中：

<% flash.each do |key, value| %>
   <div class="alert alert-<%= key %>"><%= value %></div>
<% end %>

因此，当您下次使用＆＃34替换密码时，请注意＆＃34; ＆＃34;无法登录＆＃34;

希望这有帮助！感谢

Answer 2

因为我收到错误Can't verify CSRF token authenticity。我在表单中添加了以下输入字段，它开始显示消息：

<input name="authenticity_token" type="hidden" value="<%= form_authenticity_token %>" />

无法显示闪光灯通知
