Question

在初始记录插入数据库后，我设置了 carrierwave_backgrounder ， carrierwave-video 和 carrierwave-ffmpegthumbnailer 来对视频文件进行编码（ PostgreSQL）。我遇到的问题是，我只能在Rails控制台中启动编码过程。出于某种奇怪的原因，当我使用表格时它并没有开始。我有sidekiq和carrierwave-backgrounder的默认配置设置。我也在处理mp4或webm中的每个文件。记录存储到数据库中，其中video列为null。它在我的服务器开发日志中未显示任何有关编码或sidekiq作业的内容。我在web ui上检查了sidekiq，也没有任何内容。到目前为止，我已完成以下操作。我正在使用Rails 5.2，顺便说一句。如何使用sidekiq和carrierwave_background成功编码视频？

carrierwave_backgrounder.rb

CarrierWave::Backgrounder.configure do |c|
  c.backend :sidekiq, queue: :carrierwave
end

sidekiq.rb

require 'sidekiq'

Sidekiq.configure_client do |config|
  config.redis = {:size => 1}
end

Sidekiq.configure_server do |config|

end

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:

记录提交后，没有将Sidekiq作业添加到队列中
