Question

我正在使用rails mvc，我正在使用angularjs（相当新的）用于各种javascript函数。我有一些id的数组，我想通过$ http post方法发送到我对应的rails controller的create方法。

我的服务是：

.service('teamService' , function ($http) {
  var TeamService = {};
  TeamService.saveTeam = function(player_ids) {
  $http.post('/user_teams',player_ids)
  .success(function(data,status){
    data = player_ids;
    status =  true;
});
};

相应的角度控制器功能是：

    $scope.saveTeam = function () {
  var mf = $scope.getIDs($scope.Midfielders.data);
  var df = $scope.getIDs($scope.Defenders.data);
  var fw = $scope.getIDs($scope.Forward.data);
  var gk = $scope.getIDs($scope.GoalKeeper.data);
  var player_ids = mf.concat(df,fw,gk);
  teamService.saveTeam(player_ids);
};

当我在视图中单击按钮调用控制器saveTeam函数时，它会在控制台中显示错误422无法处理的条目。我做错了什么？

根据错误消息，我相信您的发布请求会转到您的Rails控制器，但这是错误发生的地方。

Angular方面的一个调整可以帮助进行故障排除，通常是一个很好的做法，可以处理http调用的错误情况。

所以而不是

If RemoveWhitespace(tbxSubmit.Text) = RemoveWhitespace(GetCell(x, 0)) Then

也许尝试类似的事情：

DECLARE @sales table(
itemnumber int,
saledate date,
saleid int)

SELECT s.itemnumber, 
right(convert(varchar, fd.firstsaledate, 103), 7) AS firstsale, 
COUNT(*) as firstmonthsales FROM @sales s
INNER JOIN 
(SELECT itemnumber, Min(saledate) as firstsaledate FROM @sales 
GROUP BY itemnumber) as fd
ON MONTH(s.saledate) = MONTH(fd.firstsaledate) 
AND YEAR(s.saledate) = YEAR(fd.firstsaledate)
AND s.itemnumber = fd.itemnumber
GROUP BY s.itemnumber, fd.firstsaledate

.then（）的第一个函数是处理http调用成功结果的函数，只有在http调用发生错误时才会调用第二个函数。
