New Post: Count invalid items in a model
Simple validation, loops over all the boxes and makes sure you enter something into at least one of them. RuleFor(model => model.AnyInvoicesEntered) .NotEmpty() .When(AtLeastOneValueEntered)...

I see how you can re-use a validator for Complex Properties and Collections, but how will it work when the reference is bi-directional? Will the example below produce an infinite loop, and if so what...

You could probably use T4 templates to generate your validation classes. Look at the Reverse Engineer Code First in Entity Framework Power Tools. It gives you the option to generate your model,...

View ArticleNew Post: Passing an object while validating
Hi Amit FluentValidation isn't really designed to work this way - all the context should be driven by properties on the object you're validating, not by passing in anything extra. The best way to do...
View ArticleNew Post: Validating Object Graphs
Hmm yes, so this does happen in the validator's constructor, not actually at the time of validation, so marking the entity itself as already validated won't actually help. Essentially your validator...
