Rails validation message error?

Question

I want to do something like this:

validates_presence_of :name, :message => custom_message

def custom_message
  "Custom Message"
end

But when I try it I get "undefined local variable or method for custom method"

Whats up with that?

Think I figured it out. If you use a symbol instead of the method directly.

e.g :message => :custom_message

I got it working like this:

def self.custom_message
  "Custom Message"
end

validates_presence_of :name, message: custom_message

Have you tried putting the definition of custom_message before the validates_presence_of line? validates_presence_of is a class method, and when it is evaluated Ruby has not yet seen the definition below it.
