包括ASP.Net 2.0的身份和UserManager.Users.ToListAsync财产UserManager.FindByIdAsync [英] Include property on ASP.Net Identity 2.0 UserManager.Users.ToListAsync and UserManager.FindByIdAsync

问题描述

我想实现Asp.Net 2.0身份。我曾经的帮助下<托管的迄今为止非常好href=\"http://typecastexception.com/post/2014/06/22/ASPNET-Identity-20-Customizing-Users-and-Roles.aspx\"相对=nofollow称号=本博客>这个博客。但我去一个稍微不同的道路。我想一些数据不被用户对象的一部分，而是一个新创建的Customer对象。我想保持的身份验证和授权数据从我的业务数据分开。

I am trying to implement Asp.Net Identity 2.0. I have managed so far very well with the help of this blog. But I went a slightly different road. I want some data not to be part of the User object, but rather of a newly created Customer object. I want to keep the authentication and authorization data separate from my business data.

所以在我的情况下，我加入了客户财产修改ApplicationUser类：

So in my case I modified the ApplicationUser class by adding a customer property:

    public Customer Customer { get; set; }

Customer类看起来是这样的：

The Customer class looks like this:

public class Customer
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Insertion { get; set; }
    public Gender Gender { get; set; }
    public DateTime Birthdate { get; set; }
    ...etc.
    public virtual ApplicationUser User { get; set; }
}

我还增加了德关系的ApplicationDbContext：

I also added the relationship in de the ApplicationDbContext:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>()
            .HasRequired(u => u.User);
        base.OnModelCreating(modelBuilder);

    }

所以，现在一些修改寄存器视图模型，我能够注册为用户，并同时拥有在AspNetUsers表中创建一个用户记录，并在客户表中的客户记录与该用户记录的引用控制器后。到目前为止好。

So now after some modifications to the register viewmodel and the controller I am able to register as a user and have both a User record created in the AspNetUsers table and a Customer record in the Customer table with a reference to the User record. So far so good.

但现在当我检索例如，用户对于显示目的客户属性为空。这是有道理的，因为没有加载基础记录。通常我会用.INCLUDE关键字加载相关记录。但我不知道如何使用随Asp.Net 2.0标识默认的UserManager时做的。

But now when I retrieve the user for example for display purposes the Customer property is empty. Which makes sense, since the underlying record is not loaded. Normally I would use the .Include keyword to load the related records. But I don't know how to do that when using the default UserManager that comes with Asp.Net identity 2.0.

有谁知道如何实现这一目标？

Does anybody know how to achieve this?

推荐答案

我找到了答案。 Probablu需要回答之前更多的搜索。答案是基于这个答案的 SO问题

I found the answer. Probablu need more searching before answering. The answer is based on the answer in this SO Question

我添加了一个名为ApplicationUserStore类。

I have added a class called ApplicationUserStore.

public class ApplicationUserStore : UserStore<ApplicationUser>
{
    public ApplicationUserStore(DbContext context)
        : base(context)
    {
    }

    public override System.Threading.Tasks.Task<ApplicationUser> FindByIdAsync(string userId)
    {

        return Users.Include(u=>u.Customer).Include(u => u.Roles).Include(u => u.Claims).Include(u => u.Logins).FirstOrDefaultAsync(u => u.Id == userId);
    }
}

在这个类我已经重写了FindByIdAsync包括客户记录。

In this class I have overriden the FindByIdAsync to include the customer record.

然后我IdentityConfig.cs的方法创建，使其通过新创建的ApplicationUserStore代替UserStore的返回的ApplicationUserManager改变了第一道防线。

Then I changed in IdentityConfig.cs the first line in the method Create which returns the ApplicationUserManager so that it passes the newly created ApplicationUserStore instead of the UserStore.

var manager = new ApplicationUserManager(new ApplicationUserStore(context.Get<ApplicationDbContext>()));

我大概也有覆盖其他一些获取方法，包括客户记录。

I probably also have to override some other fetching methods to include the customer records.
