Hi

    What I understood is you have to check presence of phone number and 
mobile number But not at the same time Right? If so please try the 
following Assuming you have the fields phone_number and mobile_number


validates_presence_of :mobile_number,:if => :phone_number_blank_check
validates_presence_of :phone_number,:if => :mobile_number_blank_check

def phone_number_blank_check
        self.phone_number.blank?
end

def mobile_number_blank_check
        self.mobile_number.blank?
end

I found another problem when i use this code

validates_presence_of :mobile_number,:if => :phone_number_blank_check
validates_presence_of :phone_number,:if => :mobile_number_blank_check

def phone_number_blank_check
        self.phone_number.blank?
end

def mobile_number_blank_check
        self.mobile_number.blank?
end

when both field leave blank, it happened two message told that
mobile_number can''t be blank and phone_number can''t be blank

i want it to appear only one message tell that
phone number or mobile number can''t be blank, how could i do that.

Write your own validate routine instead of using the helpers.

You can do like

def validate
        validate_phone_and_mobile([mobile_number,phone_number])
end

def validate_phone_and_mobile(numbers)

                errors.add_to_base("phone number and/or mobile number 
can''t be blank") if (numbers.first.blank? or
numbers.second.blank?) or
(numbers.first.blank? and numbers.second.blank?)

end

I have something like this in one of my apps for email and cell:

validate :presence_of_email_or_cell

def presence_of_email_or_cell
    errors.add("Either an email address or cell phone number is
required") if email.blank? and cell_number.blank?
end
