轨道通知不出现 [英] rails notices not appearing
本文介绍了轨道通知不出现的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在使用Bootstrap的Rails 4中
$ p> def创建
@contest = Contest.new（contest_params）
如果@ contest.save
flash [：notice] =比赛已成功保存
redirect_to @contest
else
redirect_to root_path，：notice => '未保存的项目'
结束
结束
怎么没有通知当我提交表格？有什么我失踪？我是初学者，一直没能弄清楚。
我的布局中已经有了以下内容：
<体>
< p class =notice><％= flash [：notice]％>< / p>
< p class =alert><％= flash [：alert]％>< / p>
<％= render'layouts / header'％>
<％= yield％>
<％= render'layouts / footer'％>
< / body>
解决方案
flash [：notice] ='项目保存成功'解决方法如果您想尝试：
redirect_to about_path
redirect_to url，：flash => {：notice => notice}
同时编辑布局
$ b删除布局标头，以免发生冲突。
< body>
< p class =notice><％= flash [：notice]％>< / p>
< p class =alert><％= flash [：alert]％>< / p>
<％= yield％>
<％= render'layouts / footer'％>
< / body>
I'm in Rails 4 using Bootstrap
This is my create action in my controller:
def create @contest = Contest.new(contest_params) if @contest.save flash[:notice] = "Contest saved successfully" redirect_to @contest else redirect_to root_path, :notice => 'Project not saved' end endHow come there is no notice when I submit the form? Is there something I am missing? I'm a beginner and have not been able to figure this out.
I have the following in my layout already:
<body> <p class="notice"><%= flash[:notice] %></p> <p class="alert"><%= flash[:alert] %></p> <%= render 'layouts/header' %> <%= yield %> <%= render 'layouts/footer' %> </body>
解决方案try like this:
flash[:notice] = 'Project saved successfully' redirect_to about_pathredirect with flash was broken in some versions. Workaround if you want to try:
redirect_to url, :flash => { :notice => "notice" }also edit your layout
Remove the layouts header in case it conflicts.
<body> <p class="notice"><%= flash[:notice] %></p> <p class="alert"><%= flash[:alert] %></p> <%= yield %> <%= render 'layouts/footer' %> </body>
