Question

This is probably something stupid, but I don’t know nearly enough about rails & ruby to see it. I have the following schema & view but I am getting the error mentioned below. Business inherits from a Devise Account so thats where the email & password come from.

Any help would be greatly appreciated, thanks!

schema:

  create_table "businesses", :force => true do |t|
    t.string   "name"
    t.string   "street"
    t.string   "city"
    t.string   "zip"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

View:

#registrationForm
  -semantic_form_for(resource, :as => resource_name, :url=> registration_path(resource_name)) do |f|
    =f.input :name
    =f.input :email
    =f.input :password
    =f.input :password_confirmation
    =f.buttons

Error:

undefined method 'name' for
<Business:0x000000052690f8 > Extracted source (around line #3):

---

Edit

Controller

class BusinessesController < Devise::RegistrationsController 
  respond_to :html
   def new
     super
     @business = Business.new
   end
end

Routes.rb

  devise_for :accounts 
  devise_for :businesses, :controllers => { :registrations => "businesses" }
  

Model

class Business < Account 
end

console after reloading schema

k = Business.new ( :name =>"test" )
                          ^

You have a table named ‘accounts’ and a table named ‘businesses’.

Account is being made by devise, and has all its attributes, and points to the ‘accounts’ table.
Business inherits from Account, and therefore is using Rails’ STI (single table inheritance) features. It therefore points to the ‘accounts’ table as well.

If you were to have Business < ActiveRecord::Base it would point to your ‘businesses’ table. ActiveRecord’s STI mechanism is very strange.

I think you need to think more about how you want your data model to work. Perhaps Business should belong_to :account and have an according :account_id.

Either that or you could add all the ‘businesses’ columns to the accounts table.
