我正在使用rails 5.2,Shrine 2.19和tus server 2.3进行可恢复文件上传
routes.rb
mount Tus::Server => '/files'
model,file_resource.rb
class FileResource < ApplicationRecord
# adds an `file` virtual attribute
include ResumableFileUploader::Attachment.new(:file)
controllers / files_controller.rb
def create
file = FileResource.new(permitted_params)
...
file.save
config / initializers / shrine.rb
s3_options = {
bucket: ENV['S3_MEDIA_BUCKET_NAME'],
access_key_id: ENV['S3_ACCESS_KEY'],
secret_access_key: ENV['S3_SECRET_ACCESS_KEY'],
region: ENV['S3_REGION']
}
Shrine.storages = {
cache: Shrine::Storage::S3.new(prefix: 'file_library/shrine_cache', **s3_options),
store: Shrine::Storage::S3.new(**s3_options), # public: true,
tus: Shrine::Storage::Tus.new
}
Shrine.plugin :activerecord
Shrine.plugin :cached_attachment_data
config / initializers / tus.rb
Tus::Server.opts[:storage] = Tus::Storage::S3.new(
prefix: 'file_library',
bucket: ENV['S3_MEDIA_BUCKET_NAME'],
access_key_id: ENV['S3_ACCESS_KEY'],
secret_access_key: ENV['S3_SECRET_ACCESS_KEY'],
region: ENV['S3_REGION'],
retry_limit: 3
)
Tus::Server.opts[:redirect_download] = true
[我的问题是我无法覆盖generate_location
类的Shrine
方法,以将文件存储在AWS s3中的不同文件夹结构中。
所有文件都在s3://bucket/file_library/
(在tus.rb中提供的前缀)中创建。我想要类似s3://bucket/file_library/:user_id/:parent_id/
的文件夹结构。
[我发现Tus配置覆盖了我的所有resumable_file_uploader
类自定义选项,并且对上载没有影响。
resumable_file_uploader.rb
class ResumableFileUploader < Shrine
plugin :validation_helpers # NOT WORKS
plugin :pretty_location # NOT WORKS
def generate_location(io, context = {}) # NOT WORKS
f = context[:record]
name = super # the default unique identifier
puts "<<<<<<<<<<<<<<<<<<<<<<<<<<<<"*10
['users', f.author_id, f.parent_id, name].compact.join('/')
end
Attacher.validate do # NOT WORKS
validate_max_size 15 * 1024 * 1024, message: 'is too large (max is 15 MB)'
end
end
那么,如何使用tus选项在S3中创建自定义文件夹结构(因为神社选项不起作用?
#generate_location
,而是由tus-ruby-server
决定位置。
