Question

我的rails应用程序遇到了一个非常令人困惑的问题。我试图在页面上显示图像，我知道路径是正确的。这由＆＃34; test.html＆＃34;验证，其全部内容为：

<img src="/Users/xxxxx/MHE_website/app/assets/images/aggi5.jpg" >

当我在本地加载此页面时，我会看到图片。但是，当我将它放入我的rails应用程序时，完全相同的文本不会加载。是什么赋予了？我注意到当我在本地托管进行开发时，我在终端中收到以下错误消息：

ActionController::RoutingError (No route matches [GET] "/Users/xxxxx/MHE_website/app/assets/images/aggi5.jpg"):

这是什么意思？我以前从来没有这样做过。以下是我的Gemfile，这可能或可能不相关，但我不知所措。

Answer 1

您需要使用image_tag帮助程序在应用程序中显示图像。请参阅documentation。

你应该在你的视图中使用这样的东西：

<%= image_tag( 'aggi5.jpg' ) %>

Answer 2

尝试将图片权限更改为777。它应该工作

图像未显示在rails app中
