Ruby/Rails - Shrine::Error (storage :store没有在ImageUploader上注册)

Question

在过去的几天里，我试图为我的应用程序添加一个新的存储配置，这样我们就可以使用Cloudinary来存储图像，使用Digital Ocean Spaces来存储其他文件。在进行了我认为需要的更改之后，当我尝试访问与ImageUploader的Attacher关联的旧模型的属性时，我得到了这个错误：

Shrine::Error (storage :store isn't registered on ImageUploader)

问题是:我没有定义一个存储“存储”，但那是因为我想要有一个image_store和一个raw_store。

这是我的config/initializers/shrine.rb

# config/initializers/shrine.rb
require "shrine"
require "shrine/storage/file_system"
require "shrine/storage/cloudinary"
require "shrine/storage/s3"

Shrine.plugin :activerecord
Shrine.plugin :cached_attachment_data # for retaining the cached file across form redisplays
Shrine.plugin :restore_cached_data # re-extract metadata when attaching a cached file
Shrine.plugin :rack_file # for non-Rails apps
Shrine.plugin :default_storage, store: :image_store

s3_options = {
  access_key_id: ENV['DO_SPACE_ACCESS_KEY_ID'],
  secret_access_key: ENV['DO_SPACE_SECRET_ACCESS_KEY'],
  bucket: ENV['DO_SPACE_SECRET_BUCKET'],
  endpoint: "https://#{ENV['REGION']}.digitaloceanspaces.com",
  region: ENV['REGION']
}

if Rails.env.development? || Rails.env.test?
  Shrine.storages = {
    raw_cache: Shrine::Storage::FileSystem.new("public", prefix: "uploads/raw_cache"), # temporary
    raw_store: Shrine::Storage::FileSystem.new("public", prefix: "uploads/raw_store"),       # permanent
    image_cache: Shrine::Storage::FileSystem.new("public", prefix: "uploads/image_cache"), # temporary
    image_store: Shrine::Storage::FileSystem.new("public", prefix: "uploads/image_store")       # permanent
  }
else
  Shrine.storages = {
    raw_cache: Shrine::Storage::S3.new(
      prefix: "raw_cache", upload_options: { acl: 'public-read' }, **s3_options
    ), # for direct uploads
    raw_store: Shrine::Storage::S3.new(
      prefix: "raw_store", upload_options: { acl: 'public-read' }, **s3_options
    ),
    image_cache: Shrine::Storage::Cloudinary.new(prefix: "image_cache", resource_type: 'image'), # for direct uploads
    image_store: Shrine::Storage::Cloudinary.new(prefix: "image_store", resource_type: 'image'),
  }
end

下面是我的ImageUploader：

class ImageUploader < Shrine
  plugin :default_storage, cache: :image_cache, store: :image_store
  plugin :validation_helpers
  plugin :data_uri
  plugin :infer_extension

  plugin :upload_options, store: ->(io, context) do
    [...]
  end

  plugin :url_options, store: -> (io, **options) do
    [...]
  end

  # I even tried that one, but no success
  Attacher.default_store :image_store

  Attacher.validate do
    validate_max_size 5*1024*1024, message: "is too large (max is 5 MB)"
  end
end

有人能帮我解决这个问题吗？

好了，我找到问题了。

一开始，我的神殿初始化器中只有2个存储空间：

[...]
Shrine.storages = {
  cache: Shrine::Storage::Cloudinary.new(prefix: "image_cache", resource_type: 'image'), # for direct uploads
  store: Shrine::Storage::Cloudinary.new(prefix: "image_store", resource_type: 'image'),
  }
[...]

出于这个原因，现在我正在更新我的存储，当我恢复之前保存的记录时，它在附件字段中使用"storage: store“保存，这与旧存储的cloudinary配置不再匹配。

所以，看起来我需要做的是:更新数据库中任何文件列的存储字段，这样它就会匹配当前的配置。
