   Field	Datatype
   name	string
   phone	string
   address	string

   Field	Datatype
   name	string
   animal_type	string
   birth_date	date
   pet_image	string

6. Start the Rails server. Use these URLs for viewing the index view of the Owners and Pets controllers:
   

   http://localhost:3000/owners
   
   http://localhost:3000/pets
   

7. Set up a one-to-many relationship between Owner and Pet by placing this line in the Owner class in apps/models/owner.rb
   

   has_many :pets
   

   and by placing this line in the Pet class in apps/models/pet.rb
   

   belongs_to :owners
   

8. Set up some validations for your project including ones that
    
   
   insure that a field is not empty
    
   insure that a field is numeric
    
   insure that a field is restricted to have a certain length
   
   
9. In the index and show views for the Pets controller, display the image of each animal by replacing the code
   

   <td><%= pet.pet_image %></td>
   

   with

   <td><%= image_tag pet.pet_image, :class => 'img' %></td>
   

10. Replace the owner_id field in /app/views/pet/_form.html.erb with a dropdown box that displays the choices for owner's names.
     
11. Add a field in the Pets index view that shows the pet count for each owner.
     
12. Add a new controller named Home with views welcome and show. The welcome view introduces Geri's Pet Salon and the show_count view that displays the current count of each animal type.
     
13. Place hyperlinks on the welcome page and the show view and to the Owners and Pets controllers:
