before.update doc is old doc before updates? Or is doc the new doc as will be saved?
opened this issue · comments
I'd like to validate doc on before.update, but apparently doc is the old doc before the modifier is applied to it. How do we validate the new doc?
Answer: use LocalCollection from minimongo:
LocalCollection._modify(doc, modifier)That modifies the doc in place, and then we can perform checks on it's new modified state.
