User Methods

You saw how to set up code to create likes, now it's time to improve the code with some additional methods.

like

To make things simpler, create a method in User for liking products.

Model Code

likes?

Add another method to user that checks if a user likes a specific product. To do this, check if the user's liked_products includes a given product.
(To find a method that check if an item exists in a collection, see Ruby Arrays or look at Ruby's enumerable docs.)

Model Code

validation

Can you add validations to the Like model to make sure every like has a user_id and product_id?

Model Code

dependent relationships

If you ever delete a user, their likes will still exist in the database.
