Finding Records

What if we want to find one specific record?

We can do this by using the find class method to look up a single record by ID. Call the method and pass in the specific ID by using the following code:

store(dev)> Product.find(1)
  Product Load (0.2ms)  SELECT "products".* FROM "products" WHERE "products"."id" = 1 LIMIT 1 /*application='Store'*/
=> #<Product:0x000000012054af08 id: 1, name: "T-Shirt", created_at: "2024-11-09 16:35:01.117836000 +0000", updated_at: "2024-11-09 16:35:01.117836000 +0000">

This generates a SELECT query but specifies a WHERE for the id column matching the ID of 1 that was passed in. It also adds a LIMIT to only return a single record.

This time, we get a Product instance instead of an ActiveRecord::Relation since we’re only retrieving a single record from the database.
