首先使用代码将ASP.NET MVC3将帖子链接到帐户模型

Question

I have a newly created ASP.net MVC3 project with all the defaults. I am using the approach to build the database. I come from a PHP background and this is my first attempt at a ASP.net project.

I created a new model called "posts" and I want to link it to the built in accounts/users system that came with the default project.

Only signed in users can add posts, and I want to know what user added what post. I want to link the posts to a single user.

In PHP I would create a FK in the posts table to the users table "posts_id" and when a user adds a new post I would fill in that field with the users's id. But there does not seem to be a ID field in the account model.

Questions

• How do I link a model to the default account system build in to ASP.net MVC3 using code first approach?
• How do I query for user fields from a view in the post controller?

Links to a tutorials would work for me. Thanks

Answer 1

FKs like posts_id is a database style reference. The object oriented way of representing that data is by giving the Account object a ICollection<Post> and by giving each Post object an Account reference field.

Eg

public class Post
{
    public Account Account { get; set; }
    ...
}

As for retrieving this data, I would suggest a repository-style service class which would be responsible for saving/loading objects to & from the DB. I am not sure exactly how the Account records get persisted in the template MVC app so I can't say how it would tie into that data. I have always used my own User DB table and thrown away all that build in Microsoft account stuff.

Good luck!
