Ruby on rails 为什么在部署refinerycms的producton模式中捕获并出错

我用refinerycms生成了一个项目。当我以开发模式（rails s）启动它时，它工作得很好

但在生产模式下，我会听到“很抱歉，出了点问题。” 我正在使用postgresql

这是我在航站楼里看到的：

更新（生产/开发模式）：

---

错误表明您有一些尚未设置的表。您是否已将开发数据库转储到生产环境中？或者，您可以通过在生产环境中的命令行运行以下命令来启动新的数据库安装：

rake db:migrate
rake db:seed

更新：

如果样式表或其他静态资产在生产环境中难以正确呈现，则可能需要设置资产预编译：

# config/application.rb
config.assets.initialize_on_precompile = true

---

我用这些命令创建了一个新的db instal，但同样的问题，您是否尝试将开发db移植到生产环境？我将数据库：testrefinerycms_production更改为testrefinerycms_development现在可以工作了，但当我转到0.0.0.0:3000/refinery/users/register时出现了一些问题，css中有一些损失。我看起来不像是在开发模式下（背景是白色的，但它应该是绿色的。请看我的答案的更新。如果这有助于解决您的问题，请考虑接受/表决这个答案是正确的。您能验证条形绿色图像资产是否实际存在于您的生产环境中？您可以在同一条路径上访问它吗？n您的开发环境？另外，仅供参考，关于内容长度的消息应该与您的应用程序是否工作有任何关系–有关更多详细信息，请参阅此答案：
