在 Entity Framework 中的 IncludeFilter 上使用 AND (&&) 运算符加上不带回嵌套/子对象

Using the AND (&&) operator on IncludeFilter in Entity Framework Plus not bringing back nested / child object

我刚刚开始使用 Entity framework Plus 来恢复具有一组复杂约束/要求的数据。我能够成功使用它,但是在 IncludeFilter() 方法内部使用 && 运算符时,我无法获取要返回的嵌套/子对象。

我有一个 Company 对象 > 每个都有多个 CommunicationLink 对象 > 每个 CommunicationLink 对象都有一个 Communication 对象。我已经计算出添加多个 'Include Filters' 可用于复制 'Or' 功能 (||),但我不能在我的生活中使用 AND 运算符来过滤结果并获得嵌套要通过的对象。下面是示例代码:

示例 1:

//2 WHERE CLAUSES
var companiesData = _dbContext.Companies
     .IncludeFilter(comp => comp.CommunicationLinks
                .Where(cmli =>
                    string.Equals(cmli.Communication.Action, "PhoneOut")
                )
                .Where(cmli => cmli.UserId == comp.AccountManager) 
                .Select(comm => comm) //I believe this is where the problem lies
      )
      .Where(co =>
           string.Equals(co.Type, "Customer")
           && string.Equals(co.Status, "Active")
           && co.Deleted != 1 
       )
       .OrderBy(c => c.Name);

示例 2:

   //USING && INSTEAD OF 2 WHERE CLAUSES
    var companiesData = _dbContext.Companies
         .IncludeFilter(comp => comp.CommunicationLinks
                    .Where(cmli =>
                        string.Equals(cmli.Communication.Action, "PhoneOut")
                        && cmli.UserId == comp.AccountManager 
                    )
                    .Select(comm => comm) //I believe this is where the problem lies
          )
          .Where(co =>
               string.Equals(co.Type, "Customer")
               && string.Equals(co.Status, "Active")
               && co.Deleted != 1 
           )
           .OrderBy(c => c.Name);

我正在尝试过滤结果以仅返回子 Communication.Action 字段为“PhoneOut”且 Communication.UserId 等于 Company.AccountManager (Id) 中的值的 CommunicationLink 记录.过滤后的结果运行良好,但是通信对象(我希望通过 .Select() 方法获得)对于这些记录返回为 null。

今天早上纠结了一段时间后,我解决了。

//2 WHERE CLAUSES
var companiesData = _dbContext.Companies
     .IncludeFilter(comp => comp.CommunicationLinks
                .Where(cmli =>
                    string.Equals(cmli.Communication.Action, "PhoneOut")
                )
                .Where(cmli => cmli.UserId == comp.AccountManager) 
                .Select(comm => comm.Communication) //forgot Communication!!
      )
      .Where(co =>
           string.Equals(co.Type, "Customer")
           && string.Equals(co.Status, "Active")
           && co.Deleted != 1 
       )
       .OrderBy(c => c.Name);
