Blog Comments MVC simple Creating new comments - asp.net-mvc

Question

I have problems getting my blog create comments working it works fine when I edit in the db putting the relation id in but I cannot get it when I use the form.
Error is here: Blogposts = id
public ActionResult BlogPost(int Id)
{
var _getSpecificBlogPost = db.Blogposts.Where(m => m.Id == Id).ToList();
return View(_getSpecificBlogPost);
}
[HttpPost]
public ActionResult BlogComment_Create(string name, string bodytext, string id )
{
BlogComment model = new BlogComment { Name = name, BodyText = bodytext, Blogposts = id};
db.BlogComments.Add(model);
db.SaveChanges();
return Redirect(Request.UrlReferrer.PathAndQuery);
}
In BlogComment I have: public virtual Blogpost Blogposts { get; set; }
In BlogPosts I have: public virtual ICollection<BlogComment> BlogComments { get; set; }
<form method="post" id="form-variant-create" action="#Url.Action("BlogComment_Create", "Blog")" role="form">
<div class="form-group">
<input type="text" name="name" class="form-control" placeholder="Name" />
<br />
<textarea name="bodytext" class="form-control" rows="3" placeholder="Message"></textarea>
<input type="text" class="hidden" name="id" value="#foreach(var item in Model){#item.Id}" />
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>

Answer 1

BlogPosts is from BlogPost type. you need to create a property for your BlogPostId as ForeignKey.
public virtual int BlogPostId{get;set;}
Insert this line into your CommentModel. and then reffer to this instead of BlogPosts.
and edit your BlogPosts Property too.
[ForeignKey("BlogPostId")]
public virtual Blogpost Blogposts { get; set; }
