html - 图像未显示在 Rails 应用程序中

Question

我的 Rails 应用程序遇到了一个非常令人困惑的问题。我正在尝试在页面上显示图像，而且我知道路径是正确的。这是通过“test.html”验证的，其整体是:

<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，我的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，这可能相关也可能不相关，但我不知所措。

#   gem 'sqlite3'

您需要使用 image_tag 帮助程序在您的应用程序中显示图像。参见 documentation .

你应该在你的 View 中使用这样的东西:

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