Angular Web API $ http post排除列表

我有一個Web API（2）項目，其中有部門和員工。一個員工有一個部門，一個部門有一個員工名單。

現在在前端創建或編輯員工時，用戶必須選擇一個部門。將這個信息發佈到API中時，部門包含了員工列表（這導致了一個無效的模型狀態），我該如何防止這種情況發生？

這是我的相關設置：

型號：

public class Employee : IEntity, ICreatedOn, IModifiedOn, IMappable 
{ 
    [Key] 
    public virtual int Id { get; set; } 

    public virtual Department Department { get; set; } 

    // .. other properties 
} 

public class Department : IEntity, IMappable 
{ 
    [Key] 
    public virtual int Id { get; set; } 

    public virtual ICollection<Employee> Employees { get; set; } 

    // .. other properties 
}

的Web API控制器：

public class EmployeesController : ApiController 
{ 
    private readonly IEmployeeService _employeeService; 

    public EmployeesController(IEmployeeService employeeService) 
    { 
     this._employeeService = employeeService; 
    } 

    // .. GET, POST, DELETE etc. 

    // PUT: api/Employees/5 
    [ResponseType(typeof(void))] 
    public IHttpActionResult PutEmployee(int id, EmployeeVM employee) 
    { 
     // This is always invalid, because the employee has a department, which in turn has a list of employees which can be invalid 
     // What to do to exclude the list of employees from validation, or even better prevent from being sent to the API 
     if (!ModelState.IsValid) 
     { 
      return BadRequest(ModelState); 
     } 

     // Update etc.. 

     return StatusCode(HttpStatusCode.NoContent); 
    }

角（DataService.js）：

app.factory('DataService', 
    ["$http", 
    function ($http) { 

     return { 
      // other functions 
      updateEmployee: _updateEmployee 
     } 

     function _updateEmployee(employee) { 

      // Maybe exclude the list of employees in employee.department in here?? 
      return $http.put(employeesUrl + "/" + employee.id, employee); 
     } 

     // .. other functions 
    }]);

注意事項：

它發生在認沽和後兩者（更新和創造）
我使用AutoMapper映射到的ViewModels，看起來一樣的實體
我使用實體框架對於ORM

我已經試過：

[JsonIgnore]在Employees集合屬性;這會導致僱員在加載部門時也未被加載
[綁定（排除=「僱員」）]屬性在控制器操作參數中，這沒有任何影響
[Bind（Exclude =「Department.Employees 「）]相同

什麼工作，但我敢肯定，必須有一個更好的解決方案：

function _updateEmployee(employee) { 

    var newEmp = angular.copy(employee); 
    delete newEmp.department.employees; 
    return $http.put(employeesUrl, newEmp); 
}

顯示您的EmployeeVM請 – Artiom 2015-04-01 13:06:05

創建更新employee一個新的請求。像：

public class UpdateEmployeeRequest{ 
    public int EmployeeId {get;set;} 
    public int DepartmentId {get;set;} 
    //and so on 
}

對於此請求，您可以指定具體驗證。

，並宣佈與實體明確ID：

public class Employee : IEntity, ICreatedOn, IModifiedOn, IMappable 
{ 
    [Key] 
    public int Id { get; set; } 

    [ForeignKey("Department")] 
    public Guid DepartmentId { get; set; } 

    [Required] 
    public virtual Department Department { get; set; } 
    // .. other properties 
}

我將修改僱員實體這樣

public class Employee : IEntity, ICreatedOn, IModifiedOn, IMappable 
    { 
     [Key] 
     public virtual int Id { get; set; } 

     //Add DepartmentId 
     public Guid? DepartmentId { get; set; } 
     public virtual Department Department { get; set; } 

     // .. other properties 
    }

然後你纔可以設置DepartmentID的，就是這樣。 EF會照顧其餘的
