    Love your videos! Every time you say "Yes" whenever the copilot autofill's syntax is really satisfying. Co-pilot is really great

    Such a great introduction to the FluentValidation library. I loved that you showed that DI is supported inside of validators. Great job!

    I've been using FluentValidation for some time now and was stunned by what I saw you doing with this custom validator. Great video, thanks !

    Hi, great video as always. But I have doubts about the rules for the creation of Breakfast. I'm using a "DDD approach", so Breakfast is an Entity that has a static method "Create()" that works as Factory Method. In your example, you put the "sunrise" rules inside the DateTimeValidators and not inside the "Create()" method of Breakfast class. Is this a good approach? I have to put all the creation rules inside my “BuberBreakfast.Contracts” project and Validators or should I put the creation rules inside the Entity Breakfast?
    In short, the creation logic of an entity must be put inside our contracts or inside the Entities?
    Thanks!

      Hey Gaetano, that's an awesome question. I spent a lot of time thinking about it myself, questioning some of the recommendations, reading several blogs, and checking how some solutions behave at scale within Microsoft projects.
      For large projects with several teams/team members - I would recommend having the application layer validate the command/query, and the domain layer validate the object in the Create method, as you said.
      Will you have multiple duplicate validations? Yes. But allowing the domain models to be in an invalid state because it was already validated in the application/presentation layer assumes only the client provides invalid values when in actuality, we should also be defending our domain models from developers.
      Of course, the behavior on failure is different in each layer. Invalid request details? No problem - 400. Invalid values when trying to create a domain model? That's probably an internal error

    Hey Amichai :) I have been subscribed to your channel since your first video came out and I though it was about time to leave a comment. I really enjoy watching your videos. They are informative and at the same time fun to watch (at least for someone interested in coding and software archtiecture). At work we already use a lot of the technologies and patterns you introduced in your last videos. Nevertheless, I still learned one or two new things or got a different perspective on things. Thank you for that.

      Thanks, I'll probably do something like that in the future. For now, if you're interested, I have a video all about vscode for .NET: ruclips.net/video/m9HvsB1-hAo/видео.html
      For recording the screen, I use OBS Studio.

  • @alaamohammed3491
    @alaamohammed3491 Год назад

    if I did have the same rule for multiple proprieties (with only different parameters like max Length), Is there a way I could make a delegate or any think like this that could point at the same rule. And use it with different proprieties and there corresponding parameters.
    As it will be easier to make everything consistent, in case I wanted to change anything in the rule itself. Specially, that I have many Models and Dto that use the same rule.
    Thanks.

    Thank for the video but AddFluentValidation is deprecated and is not working with Minimal API.
    Please can make a newer video with Minimal API and show us how to validate a request without using [FromServices] IValidator

  • @DrunkyDude97
    @DrunkyDude97 Год назад

    How can we use fluent validation to validate the DTO like the behavior of Datanotations?
    Because when the validation happen later on, some of the null fields might have taken their default values by the framework.
    ex: int --> 0
    Which would miss my validations.
    So how can we validate beforehand?

  • @sunefred
    @sunefred 2 года назад

    Great library and greate demo.
    I am a bit dissapointed however that you put the validation in the controller layer and did not keep your structure, with domain and application layers, from previous chapters. If anything, validation is the core of domain functionality.

    • @amantinband
      @amantinband  2 года назад +4

      26:51 😉. This video was an introduction to FluentValidation. In the next video we'll integrate it with our Buber Dinner application as part of the application layer. We'll also discuss and the difference between application layer validations and domain layer validations.

    Fantastic playlist/work! Thank you! How would you approach fluent validation in a project with application services (without mediatr). Automatic or manual validation -> which means no pipeline behavior, but instead doing the work manually for each action?

    • @amantinband
      @amantinband  Год назад +1

      Thanks, Jim! I'd use automatic validation. If async validations are needed, I'd see if it's possible to implement some middleware/filter to do the work. Never looked into it though
