We can use Performing validations within the model works fine, but it also adds more logic to the model.
This happened only in our production environment (not staging, development or test) and when we manually tested a number of dates, a user who was 18 years and 7 days old could sign up, but a user who was 18 years and 6 days old could not. We didn't see the problem in any other environments because they get restarted so frequently.I am prototyping a rails API at work and one of my routes accepts a datetime parameter. )
A package is said to be oddly shaped if any side’s length is shorter than 10% of the longest side.Keen eyed observers will note this important phrase, “This method does not function as a validator”. I haven’t asked this to anyone who would actually have an answer, but I guess that since the docs were changed in between 1.9.3 and 2.0 I’m not the first person to try this.The super simple fix is to just use .strptime instead. ) "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 (?
We’ll have to create a virtual attribute in the We now have a much better way of inputting dates and times into Rails applications.]]
