Lesson 10 - Logging in and registration in ASP.NET Core MVC

In the previous lesson, Article administration and editor in ASP.NET Core MVC, we edited the article administration generated by Visual Studio and learned to use the TinyMCE WYSIWYG editor. In today's ASP.NET Core tutorial, we're going to add validations, use Dependency Injection and start working on the user logging so that only the administrator can edit articles.

Validations

We've already encountered validations in our course and we know that we implement them using C# attributes on the model properties. Let's modify our model:

public class Article
{
    public int Id { get; set; }
    [Required(ErrorMessage = "Fill the content")]
    public string Content { get; set; }
    [Required(ErrorMessage = "Fill the title")]
    [StringLength(100, ErrorMessage = "The title is too long")]
    public string Title { get; set; }
    [Required(ErrorMessage = "Fill description")]
    public string Description { get; set; }
}

Don't forget to add using System.ComponentModel.DataAnnotations. All the fields are required, the title is limited to the maximum length of 100 characters.

Now, we can try the improved model with validations in the article editor:
