图像显示在s3存储桶中，但是当我尝试上传它们时，网页页面没有显示任何活动，最终我在终端中得到了上面提到的错误。
这是我关于ror的第一个项目（或者是编码项目），我有点被这个问题困扰。以下是我的终端上的输出。

这是我的型号/上传器/image_uploader.rb

class ImageUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  #storage :file
  storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

end

这是我的show.html.erb文件

<p id="notice"><%= notice %></p>

  <%= image_tag @restaurant.image_url %>

<p>
  <strong>Name:</strong>
  <%= @restaurant.name %>
</p>

<p>
  <strong>Address:</strong>
  <%= @restaurant.address %>
</p>

<p>
  <strong>Phone:</strong>
  <%= @restaurant.phone %>

<p>
  <strong>Website:</strong>
  <%= @restaurant.website %>

<%= link_to 'Edit', edit_restaurant_path(@restaurant), class: "btn btn-link"  %> |
<%= link_to 'Back', restaurants_path, class: "btn btn-link"  %>
