Missing HTTP status in the response

I have a restful api built on top of a rails 3 app, i am raising a custom exception error whenever an entity is not found like below

@line = @current_account.lines.find(:first, :conditions =>{:title => line_title})
raise CustomExceptionError.new("Line not found for title: #{line_title} under your account",404) if @line.nil?

here is the look at the CustomExceptionError class

class CustomExceptionError < StandardError
  attr_accessor :message, :status
  def initialize(message,status=422)
   @message = message
   @status = status
  end
  def to_s
   "#{@message}"
  end
end

and here is the method that is used to handle the exception

def custom_error_renderer(exception = nil)
  if exception
     logger.info "Rend开发者_开发技巧ering 404: #{exception.message}"
  end
  error = {:error => {:message => exception ? exception.message : "Undefined error."}}
  render :json => error, :status => exception.status

end

But when i look at the server log

18:12:09 action_controller Completed   in 18ms
18:12:09 action_controller Rendering 404: Line not found for title: dater98 under your account

the status code is missing in the log

if i render directly instead of raising the CustomExceptionError

render :status => 404, :json => {:error => {:message=> "Line not found for title: #{line_title} under your account""}}

then it returns the status code.

Completed 404 Not Found in 84ms (Views: 75.7ms)

I have no idea what i am doing wrong here. any suggestions or guess???

If you render with a status, it will send the standard 404 response from your public/404.html file.

You could try deleting your public/404.html file.
