Rails将记录写入表

Question

I'm a newbie. I have a table called statuses. It contains status changes for records in a table called requests.

When a user creates a new request, I'd like to write a record to statuses.

How would I go about that?

Thanks

You can use after_save callback:

class Record < ActiveRecord::Base

  after_save :add_status_chanage

  def add_status_change
    status = Status.new
    status.record_id = id
    status.field = field
    status.save
  end

end
