Angular Web API $ http post排除列表

我有一个Web API（2）项目，其中有部门和员工。一个员工有一个部门，一个部门有一个员工名单。

现在在前端创建或编辑员工时，用户必须选择一个部门。将这个信息发布到API中时，部门包含了员工列表（这导致了一个无效的模型状态），我该如何防止这种情况发生？

这是我的相关设置：

型号：

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 
    }]);

注意事项：

它发生在认沽和后两者（更新和创造）
我使用AutoMapper映射到的ViewModels，看起来一样的实体
我使用实体框架对于ORM

我已经试过：

[JsonIgnore]在Employees集合属性;这会导致雇员在加载部门时也未被加载
[绑定（排除=“雇员”）]属性在控制器操作参数中，这没有任何影响
[Bind（Exclude =“Department.Employees “）]相同

什么工作，但我敢肯定，必须有一个更好的解决方案：

function _updateEmployee(employee) { 

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

显示您的EmployeeVM请 – Artiom 2015-04-01 13:06:05

创建更新employee一个新的请求。像：

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

对于此请求，您可以指定具体验证。

，并宣布与实体明确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 
}

我将修改雇员实体这样

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 
    }

然后你才可以设置DepartmentID的，就是这样。 EF会照顾其余的
