Question

有没有办法确定我的事务是否成功提交（并且没有回滚）？

Inventory.transaction do
  beads.each do |bead|
    # update something
    # insert something
    # delete something
  end
end

或者这样的事情是唯一的方法吗？

success = false
Inventory.transaction do
  beads.each do |bead|
    # update something
    # insert something
    # delete something
  end
  success = true
end

if success
  # do something
end

或者，因为异常被传播，如果没有异常就假设成功？

如果您担心异常，为什么不将它包装在try / catch块（或begin / rescue块中，以更加Rubyish）？

begin
  Inventory.transaction do
    beads.each do |bead|
      # update something
      # insert something
      # delete something
    end
  end
rescue WhateverError
  #handle error
end
