Rails:捕获 rails 控制器中的所有异常 [英] Rails: Catch all exceptions in a rails controller

问题描述

有没有办法在 rails 控制器中捕获所有未捕获的异常，像这样:

Is there a way to catch all uncatched exceptions in a rails controller, like this:

def delete
  schedule_id = params[:scheduleId]
  begin
    Schedules.delete(schedule_id)
  rescue ActiveRecord::RecordNotFound
    render :json => "record not found"
  rescue ActiveRecord::CatchAll
    #Only comes in here if nothing else catches the error
  end
  render :json => "ok"
end

谢谢

推荐答案

begin
  # do something dodgy
rescue ActiveRecord::RecordNotFound
  # handle not found error
rescue ActiveRecord::ActiveRecordError
  # handle other ActiveRecord errors
rescue # StandardError
  # handle most other errors
rescue Exception
  # handle everything else
  raise
end
