Rails4:image_url不在scss中生成摘要 [英] Rails4: image_url not generating digest in scss

问题描述

我不明白为什么我的css文件没有使用辅助方法image_url

I can't understand why my css file is not appending digests to my assets with the helper method image_url

我的资产已正确预编译，并且文件中确实包含摘要.我也可以手动访问它们(使用摘要的URL).最奇怪的是，在一开始它就起作用了.

My assets are correctly precomiled, and files do contain the digest. I also can access them (with the digested url) manually. And most strange thing is that in the beginning it was working.

这是我的配置:

  config.assets.js_compressor = :uglifier
  config.assets.compile = false
  config.assets.digest = true
  config.assets.version = '1.0'
  config.serve_static_assets = false #also tried true

这是我的application.css: * = require_tree.

here's my application.css: *= require_tree .

这是common.scss文件，用于包含图像:

here's the common.scss file, used for including an image:

body{
    background: image_url('bg.jpg');
    font-family: 'Lato', sans-serif;
    overflow-x: hidden;
}

图像以及样式表位于资产/图像和资产/样式表内的子文件夹中.

The images, as well as the stylesheets are in a subfolder inside assets/images and assets/stylesheets.

这是我的宝石:

gem 'rails', '4.0.0'
gem 'sass-rails', '~> 4.0.0'

我正在使用capistrano进行部署，但是我不认为这是与capistrano相关的问题，资产编制得很好.

I'm deploying with capistrano, but I don't think this is a capistrano related problem, assets are well compiled.

编辑 直到现在，我一直尝试过的(未成功):

EDIT What i've (unsuccessfully) tried until now:

image-url('image.jpg'); -> http://www.mydomain.it/images/image.jpg
image_url('image.jpg');    -> same as above
url(image-path('header.jpg'));  -> http://www.mydomain.it/images/image.jpg
asset-url('image.jpg', image); -> http://www.mydomain.it/image.jpg

问题仍然存在:资产已编译但没有摘要即可被请求.

problem still remains: assets are compiled but requested without digest.

编辑

遵循此问题

Following this question Rails 4 image-path, image-url and asset-url no longer work in SCSS files I moved around my assets and using the combination of asset-url and putting my assets in /public folder, background images are working, even though the problem still remains as the application is not using the timestamped version of the images. So only a (not that good, nor that bad) workaround.

推荐答案

应使用asset_path.另外，由于SCSS不会编译asset_path，因此它需要在ERB标签下运行.将common.scss重命名为common.scss.erb

Should use asset_path. Also, it needs to run under ERB tag, as SCSS does not compile asset_path. Rename common.scss to common.scss.erb

.body { background-image: url(<%= asset_path 'bg.jpg' %>) }
