How do i save the initial time a boolean went from false to true
I have a boolean column in my table and a datetime related to it. I want to be able to track down when the boolean initially turns true. In the model I have tried
def example
if boolean_field == true
datetime_field = time.now
end
end
but the problem with that is when the boolean is set to true, the datetime_field will keep updating everytime i reload the page or database since the boolean will always be in a constant state of true. I have also try to use rails dirty on it with:
boolean_field_changed?
but that method doesn't seems to update the datetime column at all. P.S i do have a before_save callback on the method.
any help on how i can save the initial time once the boolean_field changes from false to true will be much appreciated. thanks in advance
Hey Dim,
Just check to see if the time field is blank
def example
if boolean_field == true && datetime_field.blank?
datetime_field = Time.now
end
end
