Before_next_page and timeout happened

[Jiaqing Liu]

Hi Chris,

I'm trying to use a timeout on a page and tried the code on the documentation here: https://otree.readthedocs.io/en/latest/timeouts.html#timeout-seconds

When I run this I get the following error: TypeError: before_next_page() missing 2 required positional arguments: 'player' and 'timeout_happened'

The traceback shows: self.before_next_page()

How do you call before_next_page and pass the two missing arguements?

Thanks in advance,
Jia

This tutorial is for the new format. Upgrade oTree and create a new project with startproject.

Hi Chris,

By new format do you mean Otree lite? Im currently running 3.3.11

Thanks,
Jia

[Chris @ oTree]

The tutorial you are following is based on the new no-self format described here: https://otree.readthedocs.io/en/latest/misc/noself.html

If using oTree Lite (oTree 5), you can choose between the "no-self" and "self" format.

oTree 3 only supports the "self" format.

The documentation for the "self" format is here: https://otree.readthedocs.io/en/self/
