) "created_at", Mon, UTC ], ["expiration_date", nil], ["in_stock", nil], ["name", nil], ["price", nil], ["updated_at", Mon, UTC ], ["weight", nil (2.3ms) commit transaction = (0.2ms) begin transaction SQL (6.3ms) INSERT INTO "products" ("created_at", "expiration_date", "in_stock", "name", "price", "updated_at", "weight") VALUES (?

If you want a product in the database to have a unique name that appears nowhere else, then you can use this validation: product = Product.create(name: 'Milk (1 liter)') (0.1ms) begin transaction Product Exists (0.1ms) SELECT 1 AS one FROM "products" WHERE "products"."name" = 'Milk (1 liter)' LIMIT 1 (0.1ms) rollback transaction = (0.1ms) begin transaction SQL (8.7ms) INSERT INTO "reservations" ("created_at", "end_date", "room_type", "start_date", "updated_at") VALUES (?

This version uses an instance variable (@mydate) because I wrote it to be used in a Rails application.

In version 1.x of Rails scaffolding, date fields in the edit view are generated with three drop down boxes, one for the year, one for the month, and one for the day.

Product.create (0.1ms) begin transaction SQL (24.1ms) INSERT INTO "products" ("created_at", "expiration_date", "in_stock", "name", "price", "updated_at", "weight") VALUES (?

Rails began the transaction of creating a new record but for some reason it couldn't do it. The validation method intervened before the record was saved. (0.2ms) begin transaction SQL (11.2ms) INSERT INTO "products" ("created_at", "expiration_date", "in_stock", "name", "price", "updated_at", "weight") VALUES (?

Ruby throws an Argument Error if the date is invalid and in that case, the function returns false.If the object is created, the date is valid, and if not, the date is invalid.
