What is wrong with this polymorphic association?

Question

I have

class User::AuthInfo < ActiveRecord::Base
    self.table_name = "auth_infos"
    belongs_to :authenticable, polymorphic: true
end

and

class User::Customer < ActiveRecord::Base
    self.table_name = "customers"

    has_one :auth_info, as: :authenticable
end

I am expecting that by doing this:

User::Customer.last.auth_info

the output should be a record from auth_info. But I see the query is wrong:

SELECT  `auth_infos`.* FROM `auth_infos` WHERE `auth_infos`.`customer_id` = 8 LIMIT 1

My table has authenticable_id and authenticable_type, the fields that the docs tells me to create to make polymorphic work.

What is wrong? Why is it using customer_id instead of authenticable_id?

EDIT:

Here the schema of the two tables:

EDIT:

I did omit one thing, because I thinked that it was not important, but it seems to cause the problem, on the Customer model I am using a concern:

include User::Loggable

Here is the content of the concercn:

module User::Loggable
    extend ActiveSupport::Concern

    included do 
        has_one :auth_info 
    end

    def login ip_address
        @session_ip = ip_address
        create_session_token
        self.save
    end

    def renew_session
        @session_token_expire = renew_session
    end

    def destroy_session
        self.session_token = nil
        self.session_token_expire = nil
        self.save
    end

    def verify_session! (token, ip)
        if (ip == session_ip && token = session_token && session_token_expire.to_i > Time.now.to_i)
            true
        else
            false
        end 
    end


    private 

    def new_token( string = "" )
      ...
    end

    def digest_token token
        ..
    end  

    def register_user
        a = User.new email_address: self.email_address, kind: self.class.name
        a.save
    end

    def create_session_token
        @session_token = digest_token(new_token())
        @session_token_expire = (Time.now + AUTHENTICATION[::Rails.env]["expiration"]["session"].hour.to_i).strftime("%Y-%m-%d %H:%M:%S")
    end

    def renew_session
        session_token_expire = (Time.now + AUTHENTICATION[::Rails.env]["expiration"]["session"] + 3.hour).strftime("%Y-%m-%d %H:%M:%S")
    end

    module ClassMethods     
        def authenticated_account
            current_account ||= self.find_by_session_token() if CbsoltCore::App::Environment.account_session_token && CbsoltCore::App::Environment.account_session_token != ""

            # mettere parte API token
            current_account
        end
    end 
end

I've commended out the include for concern in my module, and it works. Why?

Answer 1

Your concern is overriding association including in customer model.

included do 
    has_one :auth_info, as: :authenticable
end

Either provide polymorphic association inside concern or in real model.
