Creating welcome page and new form along with controllers and views. Creating two methods in items_controller: new and create.
creating the model and updating the items controller.
creating show method in the items controller and the show view
Listing all value needs the index.html.erb in the respective view directory (note: we created an additional welcome index, and ruby returned a nil value for @items.each). We are creating index.html.erb in the items view and adding the iterator to list all items.
adding all kinds of page navigation to the project
adding validation to share items form. Learned that the Item class (found in the models/item.rb) creates an instance of item in the database. If the class Item does not exist, throws up constant item error.
