Passing Model Object Data from View, to Controller, to Model? - asp.net-mvc

Question

I'm brand new to ASP.net MVC (About a week in), so there is still quite a bit of confusion...
How do I go about passing the current views model into the controller so I can get at the model data?
View
#model KineticBomardment.Models.Blog.BlogPost
#{
ViewBag.Title = "Index";
}
#using (Html.BeginForm())
{
#Html.ValidationSummary(false)
<fieldset class="block">
<div class="input">
#Html.LabelFor(x => x.Title)
#Html.EditorFor(x => x.Title)
</div>
<div class="input">
#Html.LabelFor(x => x.ShortDescription)
#Html.EditorFor(x => x.ShortDescription)
</div>
<div class="button">
#Html.ActionLink("Submit", "CreateNewBlogEntry", "Admin" );
</div>
</fieldset>
}
I then have a controller of
public ActionResult CreateNewBlogEntry(Models.Blog.BlogPost currentBlogModel)
{
if (ModelState.IsValid)
{
currentBlogModel.CreatePost();
return Content("Created!");
}
return View();
}
And a model of
public class BlogPost
{
public int Id { get; set; }
[Required]
[Display(Name="Title of Blog Post")]
public string Title { get; set; }
public DateTime DateCreated { get; set; }
[Required]
[Display(Name = "Short Description")]
public string ShortDescription { get; set; }
public string LongDescription { get; set; }
public int HeaderImage { get; set; }
public ICollection<BlogPost> GetAllPosts()
{
ICollection<BlogPost> posts = new List<BlogPost>();
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["KineticBombardment"].ToString()))
{
using (SqlCommand cmd = new SqlCommand("select title, datecreated, shortdescription from blogentries where id > 0", connection))
{
cmd.Parameters.Clear();
connection.Open();
cmd.ExecuteNonQuery();
using (SqlDataReader reader = cmd.ExecuteReader())
{
while(reader.Read())
{
this.ShortDescription = reader["shortdescription"].ToString();
this.Title = reader["title"].ToString();
this.DateCreated = Convert.ToDateTime(reader["datecreated"].ToString());
posts.Add(this);
}
}
return posts;
}
}
}
public void CreatePost()
{
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["KineticBombardment"].ToString()))
{
using (SqlCommand cmd = new SqlCommand("insert into blogentries (shortdescription, datecreated, blogtype, title) values (#shortdescription, #datecreated, #blogtype, #title)", connection))
{
cmd.Parameters.Clear();
connection.Open();
cmd.Parameters.Add("#shortdescription", SqlDbType.VarChar, 500).Value = this.ShortDescription;
cmd.Parameters.Add("#datecreated", SqlDbType.DateTime).Value = DateTime.Now;
cmd.Parameters.Add("#blogtype", SqlDbType.Int).Value = 1;
cmd.Parameters.Add("#title", SqlDbType.VarChar, 255).Value = this.Title;
cmd.ExecuteNonQuery();
}
}
}
}

Change:
<div class="button">
#Html.ActionLink("Submit", "CreateNewBlogEntry", "Admin" );
</div>
To:
<input type="submit" class="button" />
and
public ActionResult CreateNewBlogEntry(Models.Blog.BlogPost currentBlogModel)
{
if (ModelState.IsValid)
{
currentBlogModel.CreatePost();
return Content("Created!");
}
return View();
}
to
public ActionResult CreateNewBlogEntry()
{
return View();
}
[HttpPost]
public ActionResult CreateNewBlogEntry(Models.Blog.BlogPost model)
{
if (ModelState.IsValid)
{
currentBlogModel.CreatePost();
return Content("Created!");
}
return View();
}
I've made some assumptions, but that should work
