Question

我想用自定义属性更新AspNetUsers表。我希望用户能够在注册后插入地址信息。有了代码，我没有任何错误，并且它也不会更新表。使用剃须刀页面创建模型和视图。

The table（null是我尝试更新用户时的信息，下面的信息是注册时添加地址信息时的信息）

虽然，当我让用户在注册时添加地址信息时，它确实会更新表格.Register剃刀页面是由Identity创建的，我对该项进行了脚手架并为其添加了自定义属性。

Address.cshtml.cs

let json = """
{
    "status": "200",
    "message": "Token successfully generated.",
    "data": {
        "token": "abc"
    }
}
"""

guard let jsonData = json.data(using: .utf8) else {
    fatalError("Couldn't convert the json to data")
}

struct Response: Codable {
    let status, message: String
    let data: TokenData
}

struct TokenData: Codable {
    let token: String
}

do {
    let decoded = try JSONDecoder().decode(Response.self, from: jsonData)
    if let status = Int(decoded.status) {
        print(status)
    } else {
        fatalError("The status is not an integer")
    }
} catch {
    print(error)
}

Answer 1

您是否启用迁移以更新数据库？可能正在共享日志可能会提供一些信息。我通常不首先使用代码，但是Identity Framework会创建一些触发器和东西，这些触发器和东西可能会干扰您打算添加的属性。尝试在UserModel.cs属性中添加“ nullable”，可能是表期望一个值，而注册时却没有得到一个值。我有一个类似的问题，但是让身份框架在我的数据库上创建所有东西，解决了这个问题。请注意，我的方法首先是数据库！

Answer 2

我重新创建了您的问题，并发现了以下问题。您的表显示空值的原因是事实，即方法中的参数model始终为空。

public async Task<IActionResult> OnPostAsync(InputModel model)

因此，您正在user实体上更新空值内的属性。绑定需要遵循一些约定。您在这里有两个选择：

由于您要绑定属性Input，并且具有[BindProperty]属性，其中视图在每种输入类型上使用标记asp-for="Input.name", ...，因此可以直接通过已绑定属性访问。

//get rid of parameter model, access directly in method body
    public async Task<IActionResult> OnPostAsync()
    {

      user = await _userManager.GetUserAsync(User);

      user.name = Input.name;
      user.surname = Input.surname;
      user.street = Input.street;
      user.streetnumber = Input.streetnumber;
      user.city = Input.city;
      user.zipcode = Input.zipcode;

      var result = await _userManager.UpdateAsync(user);

      return RedirectToPage();

    }

或第二个选项-您可以在方法中使用参数，但必须遵循命名约定。如果您为视图中的每个input使用类似Input.name, Input.surname, etc.的名称，则方法的参数也必须命名为Input。

public async Task<IActionResult> OnPostAsync(InputModel input)

现在您可以通过参数访问绑定的值（可以在参数名称的开头使用小写字母） 有关绑定的更多信息，请参见此link < / em>

如果我已完成所有操作，请参见上文，（没有空值）
