Hey all,
What if I want to check a column in a table to see if a value exists and
if it doesn't, then update the existing record with the specified value
and if it does exist increment by 1 from the previous incrementation of
the value. And do it using the model (or controller if it's unable to be
done in the model). Something like this:
def test!
update_attributes :student_number =>
if student_number.array.include?(2001)
Student.student_number.first(:order => "student_number
DESC").student_number + 1
else
2001
end
end
Can this be done?
Now this immediately returns a nil.array error, but what I'm more
concerned about is if it can search the table for a value and then if
exists increment by previous incrementation. Thanks for any response.
