[英]How to retrieve the latest created record using loopback api and angularjs
Below is my Modal controller. 以下是我的模态控制器。 Se_chnl and Se_segn_rqst are the Loopback models.
Se_chnl和Se_segn_rqst是回送模型。 I'm initializing the modal form in the first step.
我正在第一步中初始化模式形式。 The $scope.Se_chnl_find() is getting me a list from the backend which I load as a dropdown menu in the modal.
$ scope.Se_chnl_find()从后端获取了一个列表,该列表作为模式中的下拉菜单加载。 This call to loopback works fine.
此回送调用工作正常。
Then later on once the form is filled, I call the submit function and in that I call the create function of loopback Se_segn_rqst.create($scope.rqst) $scope.rqst contains the parameters for creating that rqst. 然后稍后在填写表单后,我会调用Submit函数,并在其中调用回送的create函数Se_segn_rqst.create($ scope.rqst)$ scope.rqst包含用于创建该rqst的参数。
Now, once I have created this "rqst", I want to retrieve ID of the latest created request by that user and store it in the global variable. 现在,一旦创建了该“ rqst”,我想检索该用户最新创建的请求的ID并将其存储在全局变量中。 But the loopback api/MySQL doesn't return anything.
但是环回api / MySQL不会返回任何内容。 Record is created in the backend when create is used.
使用create时,将在后端创建记录。 But the find function doesn't work.
但是find函数不起作用。
I tried the find filter in Strongloop/Loopback explorer and it works there. 我在Strongloop / Loopback资源管理器中尝试了查找过滤器,并且该过滤器在此起作用。 Not sure why it is not returning anything when I tried it from the controller.
不知道为什么当我从控制器尝试时它什么都不返回。
codeApp.controller('ModalInstanceCtrl', function($scope, $modalInstance, $state, Se_chnl, Se_segn_rqst) {
var defaultForm = {
cmpgn_nm: "",
cmpgn_id: "",
strgy_id: "",
rqst_typ_cd: "",
chnl_id: ""
}
$scope.channels = Se_chnl.find({
filter: {
"fields": {
"chnl_nm": true,
"chnl_id": true
}
}
});
$scope.rqst = angular.copy(defaultForm);
$scope.rqst.rqst_id = 0;
$scope.submit = function(reqForm) {
$scope.rqst.rqst_nm = $scope.rqst.cmpgn_nm;
$scope.rqst.rqst_stat_cd = 'DRAFT';
$scope.rqst.insrt_user_id = $scope.$parent.user_id;
$scope.rqst.insrt_dt = new Date();
Se_segn_rqst.create($scope.rqst);
$scope.$parent.requested_id = Se_segn_rqst.find({
filter: {
"fields": {
"rqst_id": true
},
"order": "insrt_dt DESC",
"limit": 1,
"where": {
"rqst_stat_cd": "DRAFT",
"insrt_user_id": "xyz123"
}
}
});
$modalInstance.dismiss('cancel');
};
$scope.resetForm = function(reqForm) {
$scope.rqst = angular.copy(defaultForm);
reqForm.$setPristine();
reqForm.$setUntouched();
};
});
This is the piece returning no value. 这是一块没有价值的东西。 I want an id in the requested_id global variable.
我想要一个ID全局变量Requested_id。 The filter is performing correctly in the Strongloop explorer, so there is no syntax error.
筛选器在Strongloop资源管理器中正常运行,因此没有语法错误。
$scope.$parent.requested_id = Se_segn_rqst.find({
filter: {
"fields": {
"rqst_id": true
},
"order": "insrt_dt DESC",
"limit": 1,
"where": {
"rqst_stat_cd": "DRAFT",
"insrt_user_id": "xyz123"
}
}
});
