Sharepoint 2013 App AngularJS：查找字段在添加到列表时导致错误“模型无法解析名为 'SP.Data.TeamsListItem' 的类型

Question

我有一个 Players 列表，其中 Team Name 的查找字段链接到 Teams 列表。

尝试添加或更新玩家列表时出现错误

"A type named 'SP.Data.TeamsListItem' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.".

玩家列表的 GUID 是“16a03b71-07ea-49c4-ab14-419b51047119”。

团队列表的 GUID 是“2a2916c2-22fb-4588-bca1-83479a4d85b2”。

这是错误发生时数据字段的内容：

<pre>
    "{\"__metadata\":{\"type\":\"SP.Data.PlayersListItem\"},\"Title\":\"Bill\",\"PlayerPosition\":\"Goalie\",\"Birthdate\":\"2/21/1999\",\"TeamName\":{\"__metadata\":{\"id\":\"Web/Lists(guid'2a2916c2-22fb-4588-bca1-83479a4d85b2')/Items(1)\",\"uri\":\"https://app-2971fdcf9ede6a.rawtecapps.com/sites/raiders/AngularCRM/_api/Web/Lists(guid'2a2916c2-22fb-4588-bca1-83479a4d85b2')/Items(1)\",\"etag\":\"\\"1\\"\",\"type\":\"SP.Data.TeamsListItem\"},\"Id\":1,\"Title\":\"aa\",\"ID\":1,\"$$hashKey\":\"object:176\"},\"Season\":\"2015\"}"
</pre>

我的查找字段的定义。

<pre>
    <Elements xmlns="http://schemas.microsoft.com/sharepoint/">  
      <Field

           Required="FALSE"
           Group="Custom Site Columns">
      </Field>
    </Elements>
</pre>

团队列表的内容类型：

<pre>

            </div>
        </div>
</pre>

Angular JS（玩家新控制器）：

 ><pre> 
 app.controller('playersnewController',
     function ($scope, $location, wingtipCrmService) {
         $scope.player = {};
         $scope.player.Title = "";
         $scope.player.PlayerPosition = "";
         $scope.player.Birthdate = "";
         $scope.player.TeamName = "";
         $scope.player.TeamName.Id = "";
         $scope.player.TeamName.Title = "";
         $scope.player.Season = "";
         $scope.addPlayer = function () {
             var playerName = $scope.player.Title;
             var playerPosition = $scope.player.PlayerPosition;
             var birthdate = $scope.player.Birthdate;
            var teamName = $scope.player.TeamName;
             var teamNameId = $scope.player.TeamName.Id;
             var teamNameTitle = $scope.player.TeamName.Title;
             var season = $scope.player.Season;
             wingtipCrmService.addPlayer(playerName, playerPosition, birthdate, teamName, teamNameId, teamNameTitle ,season)
               .success(function (data) {
                   $location.path("/playershome");
               });
         }
     } );
</pre>

Angular JS（添加播放器服务）：

>     <pre>
    service.addPlayer = function (PlayerName,PlayerPosition,Birthdate,TeamName,TeamNameId,TeamNameTitle,Season) {
    var restQueryUrl = "../_api/web/lists/getByTitle('Players')/items";
    var playerData = {
        __metadata: { "type": "SP.Data.PlayersListItem" },
        Title: PlayerName,
        PlayerPosition: PlayerPosition,
        Birthdate: Birthdate,
        TeamName: TeamName,
        Season: Season
    };
    var requestBody = JSON.stringify(playerData);
    return $http({
                       method: 'POST',
              url: restQueryUrl,
              contentType: "application/json;odata=verbose",
              data: requestBody,
              headers: {
                  "Accept": "application/json; odata=verbose",
                  "X-RequestDigest": requestDigest,
                  "content-type": "application/json;odata=verbose"
              }
          });
      }
</pre>

Angular JS（TeamDropDownController 和服务）：

    <pre>
    app.controller('TeamDropDownController', 
    function ($scope, wingtipCrmService) {
    wingtipCrmService.getDropDownTeams().success(function (data) {
        $scope.teams = data.d.results;
    })
});
</pre>
<pre>
service.getDropDownTeams = function () {
          var restQueryUrl = "../_api/web/lists/getByTitle('Teams')/items/" +
                             "?$select=ID,Title";
          return $http({
              method: 'GET',
              url: restQueryUrl,
              headers: { "Accept": "application/json; odata=verbose" }
          })
      }
</pre>

我是开发共享点应用程序和 Angular JS 的新手。一个多星期以来，我一直在努力寻找解决这个问题的方法，在这个过程中我学到了很多东西。

我正在使用 TeamDropDownController 加载带有团队名称的 select 语句，然后使用 playersnewcontroller 添加新玩家记录。

添加播放器 javascript 一直有效，直到我添加代码以包含 TeamName 字段。恐怕我使用控制器加载下拉列表的方式会导致 playersnewController 出现问题。

错误信息：

"A type named '{ListItemEntityTypeFullName}' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.".

通常在找不到具有指定名称的 List Item 实体时发生。在您的情况下，这意味着没有名称为 SP.Data.PlayersListItem.

的实体

以下端点允许正确确定列表项实体名称：

Uri: /_api/lists/getbytitle('{List Title}')?$select=ListItemEntityTypeFullName
Method: GET

以下jQuery示例演示了如何在创建列表项时动态确定实体类型名称：

function createListItem(webUrl,listTitle,itemProperties)
{
     var requestUri =  webUrl + "/_api/lists/getbytitle('" + listTitle + "')?$select=ListItemEntityTypeFullName";
     return executeJson({url:requestUri}).then(function(data){
          var requestUri =  webUrl + "/_api/web/lists/getbytitle('" + listTitle + "')/items";
          itemProperties['__metadata'] = {'type': data.d.ListItemEntityTypeFullName};
          return executeJson({url: requestUri, method: 'POST', data: itemProperties}); 
     });
}


var properties = {'Title':'John Doe'};
createListItem(_spPageContextInfo.webAbsoluteUrl,'Contacts',properties)
.done(function(data)
{
    console.log('List item has been created');     
})
.fail(function(error){
    console.log(JSON.stringify(error));
});

哪里

function executeJson(options) 
{
    method = options.method || 'GET';
    headers = options.headers || {};
    headers["Accept"] = "application/json;odata=verbose";
    if(method == "POST") {
        headers["X-RequestDigest"] = $("#__REQUESTDIGEST").val();
    }      
    var ajaxOptions = 
    {       
       url: options.url,   
       type: method,  
       contentType: "application/json;odata=verbose",
       headers: headers
    };
    if (typeof options.data != 'undefined') {
      ajaxOptions.data = JSON.stringify(options.data);
    }  
    return $.ajax(ajaxOptions);
}

为了解决我的问题，我添加了玩家记录但没有填写 TeamName 查找字段。然后立即使用 TeamName 字段信息执行玩家记录的更新。
