Question

运行如下所示的迁移：

def up
  FileThumb.destroy_all # delete existing thumbnails
  File.update_all(thumbs_completed: false) # reset the process flags
  File.find_each do |file|
    file.delay(priority: 8).create_thumbs # delay thumbnail creation of each file.
  end
end

我的内存报价已超出

Answer 1

这是因为在迁移中创建了太多对象，您必须更改查询，以便使用更少的内存。您的问题的答案就在这个问题中：Heroku Error R14 (Memory quota exceeded): How do I solve this?

更具体地说，修复应该是......

def up
  FileThumb.destroy_all # delete existing thumbnails
  File.update_all(thumbs_completed: false) # reset the process flags
  File.find_in_batches(batch_size: 100) do |group|
    group.each {|file| file.delay(priority: 8).create_thumbs} # delay thumbnail creation of each file.
  end
end
