ASP.NET Core 3.0 将身份用户分配给自定义 model

Question

Lets say i have model Post.cs and u want to add user who create this post.I think i can use Identity users directly and attach them to post, or maybe only their ID's. I don't want to extend it, just to assign it to the post. Here is my custom model:

 public class Post
{
    public int Id { get; set; }

    public string Title { get; set; }

    public string Content { get; set; }

    public string UserId { get; set; }

    public User User { get; set; }

    public DateTime DateCreated { get; set; }

    public DateTime? DateUpdated { get; set; }

    public DateTime DateDeleted { get; set; }

    public bool Deleted { get; set; }

    public bool Approved { get; set; }
}

On the fourth and fifth row is the APS.NET default identity user data that i want to assign to posts

I am not sure what is your question exactly. If you are trying to create a one-to-many relationship, see this simple example.

public class Post
{
    public int Id { get; set; }

    public string Title { get; set; }

    public string Content { get; set; }

    public string UserId { get; set; }

    public User User { get; set; }


}

public class User : IdentityUser
{
    public virtual ICollection<Post> Posts { get; set; }
}

This will create a one-to-many relationship between User and Posts. Post has one User but User can have multiple Posts. With that you have also extended the IdentityUser.
