How do I return HTTP error code without default template in Tornado?

which returns a html output:

Answer 1

def write_error(self, status_code, **kwargs):
    #Function to display custom error page defined in the handler.
    #Over written from base handler.
    data = {}
    data['code'] = status_code
    data['message'] = httplib.responses[status_code]
    # your other conditions here to create data dict
    self.write(TEMPLATES.load('error.html').generate(data=data))

when ever self.send_error() call is initiated write_error() function is called by the request handler. So you can create your custom error data dict here and render it to your custom error page.

http.responses[status_code] returns the error code text like "page not found" based on the status code.
