在rails 4中,我的image_tag(“assets / logo.png”)没有链接到带有摘要的文件,资产也预先编译了它们在public / assets / *中的图像
我的生产.rb:
Books::Application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests.
config.cache_classes = true

我花了2个小时试图完全解决这个选项, 为什么这不起作用?

我只是偶然发现了这个问题,解决方案非常简单: 删除输入路径的“/ assets”部分。 Rails在使用image_tag时知道在哪里查看。 请务必将图像文件放在/ assets / images。

确保您没有拼错名称,如果Rails可以在资产文件夹中找到图像,那么它将链接到已编译的资产路径。如果无法找到图片,则会链接到图片文件夹
image_tag("logo.png")
=> '/assets/logo-f2c87c4e3fda671a619ccb7...png' # if image exists
=> '/images/logo.png' # if image does not exists in asset folder
