Issue with Lua script that manages cache keys about django-cacheops

[KessoumML]

Thank you for the quick response, much appreciated !
I have a model "Record" which differ from other models only on two things

• Record inherit multiple abstract models
• Record is not cached by cacheops
  The model definition is: class Record(ModelDiffMixin, ModelMixinFoo, ModelMixin1Bar, models.Model):
  The error happens when bootstrapping the project, the following is the full error trace log

Second one is a dup of #449. BTW, one might not switch CACHEOPS_INSIDEOUT on an existing cache, it needs to be dropped. It may even corrupt your cache, which will result into similar messages with any settings.

One the first one. Can you say on which particular model is it failing?
