Validation with :if params

Rails
1

Hi all!
I’m trying to make a model validation that starts only if a given
attribute has a specified value, but it seems i’m doing something wrong
:slight_smile:

I have 3 values: respond_via, email, telephone_number. I want the latter
ones to validate only if respond_via has specific value.

So far i have:
validates_presence_of :email, :if => (:respond_via == “e-mail”)
validates_presence_of :telephone_number, :if => (:respond_via ==
“telephone”)

, but this version raises undefined method `respond_via’ exception.

I am sure it is defined, so it must be my syntax that is to blame. Any
suggestions?
