Ruby on rails Rails 5-检索图像的MiniMagick ed版本（CarrierWave/Google云存储）

我目前正在使用谷歌云存储和CarrierWave来处理我的文件上传

为了能够清楚地解释“问题”，让我们假设我有一个名为

User

的模型，它有一列

avatar

，其中包含图像字符串

用户上载其文件后，将执行以下操作：

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bucket中创建了不同版本的图像

所以问题是当我查看日志时，我意识到

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

---

@你是否包含了这个

包含CarrierWave:：MiniMagick

？可能看到这个它可以帮助你@Gabbar这个教程并没有真正的帮助，因为它没有使用谷歌云存储。。。我不确定这些图像的调用是否与AWS类似。但是，是的，我正在使用mini-magick，它允许我成功地调整和保存图像副本的大小。
