Rails Shrine图像上传到google驱动器时出错

Question

我正在尝试上传图像到谷歌驱动器使用神社。我遵循了这个gem https://github.com/verynear/shrine-google_drive_storage中的说明。

我将这个宝石添加到我的项目中

gem 'shrine'
gem 'shrine-google_drive_storage'

这是我的config/shintine.rb

require "shrine"
require "shrine/storage/google_drive_storage"

Shrine.storages = {
  cache: Shrine::Storage::GoogleDriveStorage.new(prefix: "cache"),
  store: Shrine::Storage::GoogleDriveStorage.new(prefix: "store"),
}

Shrine::Storage::GoogleDriveStorage.new(
  prefix: "store",
  google_drive_client_secret_path: "#{Rails.root}/config/client_secret.json",
  drive_public_folder_id: '0Bz_kkknizZmZRXZzeXdua1FNUXc',
  google_drive_options: {
        path: proc { |style| "#{id}_#{photo.original_filename}_#{style}" },
      },
)

但是当我尝试上传图片时，我得到了这个错误信息

NameError (undefined local variable or method `content_type' for #<Shrine::Storage::GoogleDriveStorage:0x00000004009868>):

有人知道我哪里搞错了吗？

Answer 1

您应该使用所有必需的选项初始化Shrine::Storage::GoogleDriveStorage，并将其分配给相应的神殿存储(cache和store)，如下所示：

Shrine.storages = {
  cache: Shrine::Storage::GoogleDriveStorage.new(
    prefix: "cache",
    google_drive_client_secret_path: "#{Rails.root}/config/client_secret.json",
    drive_public_folder_id: '0Bz_kkknizZmZRXZzeXdua1FNUXc',
    google_drive_options: {
      path: proc { |style| "#{id}_#{photo.original_filename}_#{style}" }
    }
  ),
  store: Shrine::Storage::GoogleDriveStorage.new(
    prefix: "store",
    google_drive_client_secret_path: "#{Rails.root}/config/client_secret.json",
    drive_public_folder_id: '0Bz_kkknizZmZRXZzeXdua1FNUXc',
    google_drive_options: {
      path: proc { |style| "#{id}_#{photo.original_filename}_#{style}" }
    }
  )
}

之后，您需要创建一个uploader类，比如ImageUploader，并在您的模型中引入一个附件属性。具体操作步骤请参考janko-m/shrine quickstart section中的步骤以适应您的需求。
