ruby-on-rails - Rails 5 - 检索 MiniMagick 版本的图像（CarrierWave/Google Cloud Storage）

Question

我目前正在使用 Google Cloud Storage 和 CarrierWave 来处理我的文件上传。

为了能够清楚地解释“问题”，假设我有一个名为的模型，该模型具有保存图像字符串User的列。avatar

用户上传文件后，完成：

version :foo1 do
  process :auto_orient
  process resize_to_fill: [150, 150]
end

version :foo2 do
  process :auto_orient
  process resize_to_fill: [250, 250]
end

version :foo3 do
  process :auto_orient
  process resize_to_fill: [350, 350]
end

它成功地在我的存储桶中创建了各种版本的图像。

所以问题出在查看我的日志时，我意识到当我这样做时

<%= image_tag(User.avatar.foo1.url) %>

查询实际上是针对图像的每一个变体执行的，因此它会foo1-3在渲染之前调用原始变体以及foo1。

所以问题是，我如何检索只需要的特定变化？（我不确定我的上传器或载波代码是否在这里必不可少。如果是，请告诉我，我会将其包含在内）

作为参考，这是我在执行时在日志中看到的内容User.avatar.foo1.url，这让我认为我正在对 Google Cloud Storage 进行“过度”调用。（我用 foo 替换了我认为可能敏感的某些细节）
