Be careful about storing something in request.vars, as some other code may depend on request.vars and end up failing due to it being changed. > Note: if you use 'detect_record_change=True' it seems 'before_update' is > called twice, though it doesn't matter in my case. > That doesn't sound right. Can you figure out where that is happening? Do you have an onchange callback that does an update on a change? Does your before_update callback return a non-falsey value in that case (that's the only reason the before_update callback would fire without being followed by an update and then the after_update callback)? Do you have record versioning enabled?
