Before save call back ruby on rails

I am doing a currently a project and I am using a devise.. In my sign up(using the devise) I have field named mobile number, when I click the sign up/submit button it will be save into my table but before it will save I concatenate the country code(+63. Example: I input 1234567891, in my table it will become like this +631234567891).

I used the before_save method/function but I am having a problem with it, whenever I click the sign in/confirm email/logout it will add another +63(so it will become +63+63....)..

Question: How can I prevent adding +63? It will only add the +63 during the sign-up

Model

before_save : add_country_code

validates :mobile_no, :presence => true,
              :numericality => true,
              :length => { :minimum => 10, :maximum => 10 }
def add_country_code
    self.mobile_no = "+63" + self.mobile_no.to_s
  end

def add_country_code
  self.mobile_no = '+63' << self.mobile_no.to_s.gsub(/\A\+63/, '')
end

You can replace before_save with before_create. Whenever you sign in, devise updates some other columns like last_signed_in_at, therefore before_save is triggered.

But really you might want to check if you have prefixed the country code, in case the user wants to update the phone number.

before_save :add_country_code, unless: :mobile_no
  • this only appends +63 when the mobile_no is blank (which happens only at sign-up, or when updating your user information provided that there was no mobile_no yet)

Your validates method is having length as 10 and that’s why while saving it is checking validation. Change validation as follows:

validates :mobile_no, presence: true,
              numericality: true,
              length: { is: 13 }

Keeping length 13 will allow you save +63 before saving. Hope this helps. Happy coding. :)

Try this one. Only update the mobile phone if the object is not persisted.

def add_country_code
  self.mobile_no = "+63" + self.mobile_no.to_s unless persisted?
end
