Checking if an associated record exists in Rails

I have two tables in my PostgreSQL database named users and businesses. When a user logs in and accesses the business/profile I first want to check if they have actually created a profile. If not, I would then like to redirect them to the business/create. So basically, what I need to do is check whether the businesses table contains a record associated with the current user. I've tried a few things I thought would work but keep getting the following error:

Couldn't find User/Business without an id.

Currently my routes file contains the following definitions:

get "business/profile"
get "business/account"
get "business/create"

devise_for :users

get "home/index"
root :to => "home#index"

I think that you're using Business.find_by_...() method, but it gives you 404 error if it does not find anything.

You should check it in this way:

def profile
  if current_user.businesses.count == 0
    redirect_to business_create_path
  else
    # ...
  end
end

I suppose that you have a User::belongs_to(Business) relation in your models.

Have a relationship between User and Business model 

class User < ActiveRecord::Base
    has_one :business
  end
class Business < ActiveRecord::Base
    belongs_to :user
end

in businees_controller.rb

class BusinessController < ApplicationController
 def profile
  redirect_to business_create_path unless current_user.business
  "your code"
 end
 def create
 end
end
