圖片未顯示在Rails應用中

Question

我的Rails應用程序存在一個非常令人困惑的問題。 我正在嘗試在頁面上顯示圖像，並且我知道該路徑是正確的。 這由“ test.html”驗證，其整體為：

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

當我在本地加載此頁面時，我看到了圖片。 但是，當我將其放入Rails應用程序時，不會加載完全相同的文本。 是什么賦予了？ 我注意到當我在本地托管進行開發時，在終端中收到以下錯誤消息：

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

這是什么意思？ 我從來沒有做過此事。 以下是我的Gemfile，這可能相關也可能無關，但我很茫然。

Answer 1

您需要使用image_tag幫助器在您的應用程序中顯示圖像。 請參閱文檔 。

您應該在視圖中使用以下內容：

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

Answer 2

嘗試將圖像的權限更改為777 。 它應該工作
