Store JS lists as Django model

[Nicholas L]

Hello,

Is oTree compatible with storing lists in model cells? I tried importing django.contrib.postgres.fields and djanog.mysql.models and then using LongTextField() or ArrayField(), but they did not seem to work. I am trying to store a dynamic range of performance.now() times from an .onclick function into an JS array to then pass onto a django model.

Cheers,

Nicholas

A few options:

- ExtraModel

- participant.vars

- LongStringField (json encoded)

Ok, thanks! I got it to work with LongStringField(). Quick question: is there a max length on the LongStringField()? At the very most, I will have a participant with a list containing 1000 elements of performance.now() values that get converted to a comma-separated string. Will this be a problem for variable storage limits or server load?

Should be fine.
