Question

Updating the code formatting for better viewing.

Folks,

I have been looking at this for sometime but I don’t understand what could be messing up here. I am using Devise.

class User < ActiveRecord::Base
  has_many :addresses
  accepts_nested_attributes_for :addresses

  # Other stuff here
end

class Address < ActiveRecord::Base

  belongs_to :user

  validates_presence_of :zip #:street_address1, 

end

——————– log output end ——————————

The zip is present in the data posted and the posted data seems to be formatted properly. On the web page form I am getting the error that “Addresses zip can’t be blank”. I have dug around for what causes the “Can’t mass-assign protected attributes” warning but haven’t found anything that will help me.

Thanks for your thoughts and pointers.

Edit:

Having accepts_nested_attributes_forin User model enables you to send the data to the Address model.

Then, in the Address model, you have to set the requested attr_accessible
