Ways to override error pages #227

Closed rjpcomputing closed 9 years ago

rjpcomputing commented 9 years ago

Hi,

I could not find a way to override the default behavior of the error 404, 400, 500 errors. I would like to automatically send a JSON "error" structure that has been defined in other apps I have written. Can these default errors be overwritten?

Thanks.

Hello.

The only way to do this at the moment is to reimplement the ErrorHandler.

turbo.web.ErrorHandler = class("ErrorHandler", web.RequestHandler)

function turbo.web.ErrorHandler:initialize(app, request, code, message)
    turbo.web.RequestHandler.initialize(self, app, request)
    if (message) then
        self:write(message)
    end
    self:set_status(code)
    self:finish()
end

Change this to whatever you want. This will be global towards all of your Applications and RequestHandlers though, so you have to run in separate processes if you want different behaviours.
