After_validation stack level too deep

I am experiencing a loop within the after_validation callback when
trying to update some model attributes. However, it looks like it is
calling validation recursively again and again and I am getting “stack
level too deep” error message. I tried using a skip_callbacks flag but
with no success.

Why is this occurring and how how to make populate_address execute just
once and not call validation.

require ‘correios-cep’
class Address < ActiveRecord::Base
attr_accessible :id, :street, :neighborhood, :city, :state, :zipcode,
:country, :is_primary, :user_id, :latitude, :longitude,
:is_accurate_points
attr_accessor :invalid_primary, :populated_address, :skip_callbacks
belongs_to :user
validates :street, presence: true
validates :city, presence: true
validates :neighborhood, presence: true
validates :state, presence: true
validates :zipcode, presence: true
validates :country, presence: true
validates :is_primary, :inclusion => {:in => [true, false]}
validate :is_primary, :invalid_primary?
validate :street, :validateStreet?
validate :zipcode, :validateZip?
after_validation :populate_address

def populate_address
self.neighborhood = populate_address.neighborhood
self.city = populate_address.city
self.street = populate_address.street
self.state = populate_address.state
end
end

If your method is called populate_address, and you have populate_address
on the second line of that method, what exactly do you expect to happen
but a loop? Is that a typo? You’ve used it over and over, and it doesn’t
seem to be defined anywhere else.

Walter,

thanks for pointing this out. I think this is the problem, let me check
and I will get back.

Thank you

Thank you. It was typo, fixed now.
