32. Model validation in ASP.NET MVC (Create Actor) | ASP.NET MVC

------------------------------------------------------------------
In this part, you will learn about model validation in ASP.NET MVC and for that you will learn how to add data to the database using the ActorsService with Entity Framework.
But, before you add any data to the database you will check if the data is valid, for that you will learn how to validate a model in ASP.NET MVC

The tutorials are great but I don't understand why you sometimes skip crucial parts. For instance, you skipped the part where you had to explain that in order to avoid the actor_movie relationship issue (because of the null value), you need to allow a nullable property in the Actor model: public List<Actor_Movie>? Actors_Movies { get; set; } I love your work but I saw this type of skipped information about 4 times.

to every one the reason why the data didn't post you need to go for model Actors where public List<Actors_Movie>? Actors_Movies { get; set; } you need add ? after < >to make it add null thank me later ^^

Hello, you are doing a great job man, but i have a problem with creating an actor. I can't create an actor when I press create button. Looks like the problem is in the cookie. The error reads like this: A cookie was not sent to an insecure origin from a secure context. Because this cookie would have been sent across schemes on the same site, it was not sent. This behavior enhances the SameSite attribute’s protection of user data from request forgery by network attackers. I did some research but couldn't figure it out, can you help me?

When I create an actor nothing happen just the page refreshed and the actor doesn't add to database

Hello to everyone!
Since i put [Required]annotations when im going to Actors menu i have sqlNullValueException.
and the error is this :
in ActorsService.cs
+
var result = await

in ActorsController.cs
+
var data = await _service.GetAll();
If i comment the annotations then the page is loading normally.
