我想通过 Shrine 上传器 gem 上传一个 xls 文件(Libreoffice),但是我收到一个回滚错误,比如文件类型必须是一个 ..(在我的初始化程序/shrine.rb 中有 mime 类型).. 这是我的神社.rb
require "shrine"
require "shrine/storage/s3"
s3_options = {
bucket: "#{Rails.application.secrets[:aws_bucket_name]}",
access_key_id: "#{Rails.application.secrets[:aws_access_key_id]}",
secret_access_key: "#{Rails.application.secrets[:aws_secret_access_key]}",
region: "#{Rails.application.secrets[:aws_region_name]}"
}
Shrine.storages = {
cache: Shrine::Storage::S3.new(prefix: "cache", **s3_options),
store: Shrine::Storage::S3.new(prefix: "store", **s3_options),
#public_store: Shrine::Storage::S3.new(public: true, upload_options: { cache_control: "max-age=15552000" }, **s3_options)
}
Shrine.plugin :activerecord
Shrine.plugin :instrumentation
Shrine.plugin :determine_mime_type, analyzer: :marcel
Shrine.plugin :cached_attachment_data
Shrine.plugin :restore_cached_data
Shrine.plugin :presign_endpoint, presign_options: -> (request) {
# Uppy will send the "filename" and "type" query parameters
filename = request.params["filename"]
type = request.params["type"]
{
content_disposition: ContentDisposition.inline(filename), # set download filename
content_type: type, # set content type (required if using DigitalOcean Spaces)
content_length_range: 0..(10*1024*1024), # limit upload size to 10 MB
}
}
Shrine.plugin :derivation_endpoint,
secret_key: "secret",
download_errors: [defined?(Shrine::Storage::S3) ? Aws::S3::Errors::NotFound : Errno::ENOENT]
这是我的神社_uploader.rb
class ShrineUploader < Shrine
plugin :processing
plugin :validation_helpers # to validate image data
plugin :versions
plugin :add_metadata
plugin :delete_raw
plugin :recache
plugin :default_storage, cache: :cache, store: :store
Attacher.validate do
validate_max_size 10.megabyte
validate_mime_type_inclusion ['image/jpg', 'image/jpeg', 'image/png', 'image/gif','image/tiff', 'application/pdf', 'application/msword', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'application/vnd.ms-excel', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/vnd.ms-powerpoint', 'application/vnd.openxmlformats-officedocument.presentationml.presentation', 'application/vnd-xls']
end
def generate_location(io, context)
#type = context[:record].class.name.downcase if context[:record]
type = context[:record].patron_id if context[:record]
style = context[:version] if context[:version]
name = super # the default unique identifier[type, style, name].compact.join("/")
end
end
我可以上传 xlsx 文件,但是即使 mime 类型是 application/vnd.ms-excel,我也无法弄清楚为什么我无法上传 xls 文件。
谢谢你的帮助。
