search_result: send request to Walmart API using the product keyword and number of search queries that the user enters in the form, and display product search results
add_product: show a form that asks for username and product id, upon entering, save the useranme and sendd a request to Walmart API with the product id to get the product name; create a user object and a product object and then check if the user and product is in databse.
