Issue with accepts_nested_attributes_for and authlogic_oauth

[kandadaboggu]

I have the following models: class Merchant acts_as_authentic has_one :store accepts_nested_attributes_for :store end class Store belongs_to :merchant end I am using authlogic_oauth gem for Twitter authentication. While registration I save the Merchant and the Store model. If I disable the oauth authentication both models are saved. When ever I enable the oauth authentication only Merchant instance is saved.

After spending some time looking at the authlogic_oauth gem code I think found the culprit. The authlogic_oauth gem stores the ActiveRecord attributes in the session during oauth calls. But it does not store the attributes of the associations.

# authlogic_oauth : lib/authlogic_oauth/acts_as_authentic.rb    
def save(perform_validation = true, &block)
    if perform_validation && block_given? && redirecting_to_oauth_server?
        # My comment: Any nested attributes are not saved in the session
        session_class.controller.session[:authlogic_oauth_attributes] = attributes.reject!{|k, v| v.blank?}
        # some code
    end
        # some code
end

I addressed the issue by saving Store attributes temporarily in the session for the duration of Oauth calls.

class MerchantsController < ApplicationController
    before_filter :init_nested_attr
    def create
        @merchant = Merchant.new(params[:merchant])
        @merhcant.save do |result|
            #some code
        end
    end
    private
    def init_nested_attr
        if session[:authlogic_oauth_attributes]
            params[:merchant] = session[:authlogic_oauth_attributes]
            params[:merchant][:store_attributes] = session.delete(:authlogic_oauth_store_attributes)
        else
            session[:authlogic_oauth_store_attributes] = params[:merchant][:store_attributes]
        end
    end
end

I am wondering if there is a better solution.

Thanks for this solution. I am having the same issue. Would also like to know if there is a better option.

I couldn't find anything better. Off-course the OAuth gem could be modified to store the the associations. I didn't go down that route.
