I am experiencing a loop within a after_validation when trying to update some attributes. 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 but with no success. Why is this occurring and how to fix it? 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 Application Trace | Framework Trace | Full Trace Request Parameters: {"utf8"=>"✓", "_method"=>"patch", "authenticity_token"=>"moURPhSZblDM6t70lg59TWUuDS8k6K/ygf8zMY1UBjE=", "address"=>{"zipcode"=>"88025-100", "street"=>"Rua Allan Kardec 35", "neighborhood"=>"Agronômica", "city"=>"Florianópolis", "state"=>"SC", "is_primary"=>"true"}, "commit"=>"Atualizar", "id"=>"2"} Toggle session dump Toggle env dump Response Headers: None -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
