Rails 4 - 图像未显示在模型的新页面上

Question

I have a sidebar file in my /views/layouts/ folder that has a header image accessible at /assets/images/ However, when I go to localhost:3000/books/new the sidebar header image is unable to be displayed. 我的/ views / layouts /文件夹中有一个侧边栏文件，其头文件图像可在/ assets / images /访问。但是，当我转到localhost:3000/books/new ，无法显示侧边栏标题图像。 Looking in the terminal, it's looking for the header image in /books/assets/images/ 在终端中寻找/ books / assets / images /中的标题图片

Is there a way to fix this error quickly without having to copy my images into new folders? 有没有办法快速修复此错误，而无需将我的图像复制到新文件夹？

Answer 1

In Rails, if you need reference an asset on pages, you should use asset helpers. 在Rails中，如果您需要在页面上引用资产，则应使用资产助手。 In this case, you can change the line: 在这种情况下，您可以更改行：

%img#menu-image{src: "assets/books.png"}

to 至

%img#menu-image{src: "#{image_path('books.png')}"}

Answer 2

Rails comes with a whole lot of view helpers to help you generate HTML easily. Rails附带了大量的视图助手，可以帮助您轻松生成HTML。 one of these is image_tag . 其中一个是image_tag 。

Use it like so: = image_tag 'books.png', :id => 'menu-image' 像这样使用它： = image_tag 'books.png', :id => 'menu-image'
