HOw do I perform this conditional validation?

Rails

Hi,

I have this validation rule to check if the user-entered date of birth
is at least 18 years of age …

validates_each :date_of_birth do |record, attr, value|
record.errors.add attr, “You must be at least 18 years old to
use this site.” if value > Date.new((Date.today.year - 18),
(Date.today.month),(Date.today.day))
end

Now I want to refine this so it validation only occurs if this
condition above is true and the user_type_id virtual attribute is
equal to one. How do I add this additional piece of logic into my
validation rule?

Thanks, - Dave

Just add record.user_type_id == 1 to that condition.

I guess I’m slow. How would that look with the code above? -

Thanks. I think I’m still doing something wrong because I now have

validates_each :date_of_birth do |record, attr, value|
record.errors.add attr, “You must be at least 18 years old to
use this site.” if :user_type_id != 1 && value >
Date.new((Date.today.year - 18),(Date.today.month),(Date.today.day))
end

but I’m getting an error upon trying to create my object. The error
is

NoMethodError in Super admin/subscriberController#create
You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.>

app/models/user.rb:10
