Action Job can't seem to find an Action Storage attachment with error: Errno::ENOENT (No such file or directory @ rb_sysopen
问题
It seems like you're encountering an issue with the file path when trying to transcribe audio using the openai gem in your Rails application. The error message "Errno::ENOENT (No such file or directory @ rb_sysopen)" indicates that the system is unable to find the file at the specified path.
In your code, you are using transcription.audio_file_url to obtain the file URL, and then trying to open it using File.open(file_path, "rb"). However, the File.open method expects a local file path, not a URL.
To resolve this issue, you should download the file from the URL and then pass the local path to File.open. Here's a modified version of your TranscriptionJob perform method to achieve this:
class TranscriptionJob < ApplicationJob
queue_as :default
require 'openai'
require 'open-uri'
def perform(transcription)
client = OpenAI::Client.new(access_token: Rails.application.credentials.dig(:openai, :api_key))
logger.info "SMC DEBUG: OpenAI Key set"
file_url = transcription.audio_file_url
begin
# Download the file from the URL to a temporary location
temp_file = Tempfile.new(['audio', '.mp3'])
temp_file.binmode
open(file_url, 'rb') do |url_file|
temp_file.write(url_file.read)
end
temp_file.rewind
response = client.transcribe(
parameters: {
model: "whisper-1",
file: temp_file
})
logger.info "SMC DEBUG: transcription sent"
# Update the transcription object with the returned text
transcription.transcriptionresult = response['text']
logger.info "SMC DEBUG: TranscriptionResult is: #{transcription.transcriptionresult}"
# Save the updated transcription object
transcription.save
ensure
temp_file.close
temp_file.unlink
end
end
end
This code downloads the file from the URL, saves it to a temporary location, and then opens it using File.open. Make sure to require 'open-uri' at the beginning of your code to use the open method.
This should resolve the "No such file or directory" error and allow you to transcribe the audio correctly.

I have a Rails 7.0.4 app in which I have a simple TranscriptionController that once a form with the title, description and audio_file are submitted, an Action Job is kicked off to process an audio transcription using the openai gem. I keep getting this error in spite of the URL being produced as pointing to the audio_file I want transcoded:
Errno::ENOENT (No such file or directory @ rb_sysopen
Here is the Transcription model:
class Transcription < ApplicationRecord
has_one_attached :audio_file
def audio_file_url
Rails.application.routes.url_helpers.url_for(audio_file) if audio_file.attached?
end
end
Here is the create action in the TranscriptionController:
def create
@transcription = Transcription.new(transcription_params)
respond_to do |format|
if @transcription.save
# Process audio file using OpenAI's Whisper API
TranscriptionJob.perform_later(@transcription)
format.html { redirect_to transcription_url(@transcription), notice: "Transcription was successfully created. Check back later for transcription text." }
format.json { render :show, status: :created, location: @transcription }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: @transcription.errors, status: :unprocessable_entity }
end
end
end
And here is the most important part, the Active Job called transcription_job.rb:
class TranscriptionJob < ApplicationJob
queue_as :default
require 'openai'
def perform(transcription)
# Do something later
client = OpenAI::Client.new(access_token: Rails.application.credentials.dig(:openai, :api_key))
logger.info "SMC DEBUG: OpenAI Key set"
file_path = transcription.audio_file_url
logger.info "SMC DEBUG: Audio file path is: #{file_path}"
response = client.transcribe(
parameters: {
model: "whisper-1",
file: File.open(file_path, "rb")
})
logger.info "SMC DEBUG: transcription sent"
# Update the transcription object with the returned text
transcription.transcriptionresult = response['text']
logger.info "SMC DEBUG: TranscriptionResult is: #{transcription.transcriptionresult}"
# Save the updated transcription object
transcription.save
end
end
Here is some relevant feedback from the Rails logs for the Action Job:

When I try to put that url in my browser it downloads the correct file.
I have tried to use the following to reference the path instead of the URL:
file_path = Rails.application.routes.url_helpers.rails_blob_path(transcription.audio_file, only_path: true)
But this gives me a similar error pointing to the path instead of the url:

I am at a loss for how to address this problem. I would love to find an answer from the brain trust.

感谢 @Chiperific 指向这个边缘指南：https://edgeguides.rubyonrails.org/active_storage_overview.html#downloading-files。这帮助我按照以下方式重写我的代码。关键是将文件下载到系统的临时文件位置，然后在openai API中指向该本地路径。
class TranscriptionJob < ApplicationJob
queue_as :default
require 'openai'
def perform(transcription)
# 提供openai API密钥并初始化openai客户端的实例
client = OpenAI::Client.new(access_token: Rails.application.credentials.dig(:openai, :api_key))
# 初始化transcriptionresult变量
transcription.transcriptionresult = ''
# 必须首先将文件下载到临时存储位置，然后使用openai API提交。
transcription.audio_file.open do |file|
# 我在应用根目录创建了一个名为“transcribe”的文件夹
system '/tmp/transcribe', file.path
response = client.transcribe(
parameters: {
model: "whisper-1",
file: File.open(file.path, "rb")
})
# 使transcriptionresult等于openai转录产生的response['text']。
transcription.transcriptionresult = response['text']
# 保存更新后的transcription对象
transcription.save
end
end
end

Thank you for @Chiperific pointing me to this edge guide: https://edgeguides.rubyonrails.org/active_storage_overview.html#downloading-files This helped me to rewrite my code as follows. The key is to download the file to a temporary file location on the system and then point to that local path in the openai API.
class TranscriptionJob < ApplicationJob
queue_as :default
require 'openai'
def perform(transcription)
# Provide the openai API key and initialize an instance of the openai client
client = OpenAI::Client.new(access_token: Rails.application.credentials.dig(:openai, :api_key))
# Initialize the transcriptionresult variable
transcription.transcriptionresult = ''
# It is necessary to download the file to temporary storage location first and then submit with the openai API.
transcription.audio_file.open do |file|
# I created a folder in the app root /tmp called “transcribe”
system '/tmp/transcribe', file.path
response = client.transcribe(
parameters: {
model: "whisper-1",
file: File.open(file.path, "rb")
})
# Make the transcriptionresult equal to the response['text'] produced by the openai transcription.
transcription.transcriptionresult = response['text']
# Save the updated transcription object
transcription.save
end
end
