Thanks for your answer. I would use the instance variable, but if my
code in the model looks like:
validate :minutes_editable
...
def minutes_editable
if minutes_closed_was
errors.add(:minutes_closed, "specifies that the board is closed.
To reopen, use contextual menu action.")
end
end
where minutes_closed is the boolean field that just can be passed from
true to false by executing the "reopen" action.
How would you use the before_validation callback?
