I don’t think you’re going to be able to do this without restricting yourself to certain issuing countries. If you look at the specs of machine readable passports: http://www.highprogrammer.com/alan/numbers/mrp.html It says that each country is free to use any format it likes for the actual passport number (including letters or digits). Although in the machine … Read more
Absolutely, validation is the process of approving a given object state, while invariant enforcement happens before that state has even been reached. A corollary is that invariant enforcement is best performed by the thing that is being mutated (or created) itself, like a self-protection reflex, whereas validation is usually done by a third party. The … Read more
In the past, it was true that joi lacked browser support, at least out of the box. It uses a few Node.js APIs, which aren’t available in the browser, to implement some of its features. It was still possible to use Browserify on it, or use the unofficial joi-browser npm package, but the process was … Read more
You can manually call Validate() by passing in a new instance of ValidationContext, like so: [HttpPost] public ActionResult Create(Model model) { if (!ModelState.IsValid) { var errors = model.Validate(new ValidationContext(model, null, null)); foreach (var error in errors) foreach (var memberName in error.MemberNames) ModelState.AddModelError(memberName, error.ErrorMessage); return View(post); } } A caveat of this approach is that in … Read more
This works for me (kubernetes 1.7 and 1.9): kubectl apply –validate=true –dry-run=client –filename=file.yaml
In the Table annotation, you can also set an index for multiple columns. /** * @ORM\Entity * @ORM\Table(name=”ecommerce_products”,uniqueConstraints={ * @ORM\UniqueConstraint(name=”search_idx”, columns={“name”, “email”})}) */ or with YAML format: Namespace\Entity\EntityName: type: entity table: ecommerce_products uniqueConstraints: uniqueConstraint: columns: [name, email]
The solution I went with was to add a System aggregate root that could maintain a list of the current Facility names. When creating a new Facility, I use the System aggregate (only one System as a global object / singleton) as a factory for it. If the given facility name already exists, then it … Read more
Just check for null before running the rules that depend on them, using a When condition. this.CascadeMode = CascadeMode.StopOnFirstFailure; RuleFor(x => x.TechnicalHeader).NotNull().WithMessage(“Header cannot be null”); // Ensure TechnicalHeader is provided When(x => x.TechnicalHeader != null, () => { RuleFor(x => x.TechnicalHeader.Userid).NotEmpty().WithMessage(“Userid cannot be null or an empty string”); RuleFor(x => x.TechnicalHeader.CabCode).GreaterThan(0).WithMessage(“CabCode cannot be or less … Read more
Starting from Symfony 2.4 you can also use Expression validation constraint to achieve what you need. I do believe, that this is the most simple way to do this. It’s more convenient than Callback constraint for sure. Here’s example of how you can update your model class with validation constraints annotations: use Symfony\Component\Validator\Constraints as Assert; … Read more
I recently came across Google Refine (now OpenRefine) – it’s not a service for validating CSV files, it’s a tool you download locally, but it does provide a lot of tools for working with data and detecting anomalies. As mentioned in a reply, “CSV” has become an ill-defined term, principally because people don’t follow the … Read more
