SharePoint REST查询展开自引用列

Question

我有两个清单.公司和员工.我在员工列表中有一个名为"company"的查找列,该列指向员工的ID.

在我的REST查询中,我可以非常轻松地扩展公司的标题

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee')/items?$select=ID,Title,Company/Title&$expand=Company/Id&$filter=Company/Id%20eq%20%2714%27

很好!

现在,我将另一个查找列添加到名为Manager的Employee List中,并将其指向employee id

现在我如何将ManagerId扩展​​为经理头衔？

我试过了

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee2')/items?$select=ID,Title,Employee2/Title,Company/Title&$expand=Company/Id&$expand=Manager/Id&$filter=Company/Id%20eq%20%2714%27

我也试过了

http://abhi-sharepoint.abhishek.com/sites/dev/_api/web/lists/getbytitle('Employee2')/items?$select=ID,Title,Employee2/Title,Company/Title&$expand=Company/Id&$expand=Employee2/Id&$filter=Company/Id%20eq%20%2714%27

但没有任何作用.如何在同一列表中使用展开？

Answer 1

以下REST端点

/_api/web/lists/getbytitle('Employee')/items?$select=Title,Company/Title,Manager/Title&$expand=Company/Id,Manager/Id 

返回Employee Title,Company Title并且Manager Title,其中Managerfield是Lookup同一个List的a

例:

var query = "/_api/web/lists/getbytitle('Employee')/items?$select=Title,Company/Title,Manager/Title&$expand=Company/Id,Manager/Id";
$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + query,
    type: "GET",
    headers: { "ACCEPT": "application/json;odata=verbose" },
    success: function(data){
      $.each(data.d.results, function(idx,item){
          console.log(item.Title); //Employee Title
          console.log(item.Company.Title); //Company Title
          console.log(item.Manager.Title); //Manager Title
      });
    },
    error:  function(data){
      console.log(JSON.stringify(data));
    }
});
