与AngularJS UI格$ scope.saveRow保存行数据 [英] Saving row data with AngularJS ui-grid $scope.saveRow
问题描述
我工作的一个小的前端应用，这将在UI格显示不同的产品航次。
I'm working on a small frontend application which will show various product shipping data in a ui-grid.
我有以下的code：
HTML：
<body ng-controller="MyCtrl">
<p ng-repeat="row in myData">{{row.name}} works at {{row.company}}</p>
<button type="button" class="btn btn-success" ng-click="getCurrentFocus()">Get Current focused cell</button> <span ng-bind="currentFocused"></span>
<br/>
<br/>
<div id="grid1" ui-grid="gridOptions" external-scopes="editRows" ui-grid-edit ui-grid-row-edit ui-grid-pinning ui-grid-paging ui-grid-cellnav class="grid"></div>
</body>
AngularJS：
var app = angular.module('webapps', ['ngAnimate', 'ui.grid', 'ui.grid.edit', 'ui.grid.rowEdit', 'ui.grid.pinning', 'ui.grid.paging', 'ui.grid.cellNav']);
app.controller('MyCtrl', ['$scope', '$http', '$q', '$interval', function ($scope, $http, $q, $interval) {
//Column definitions
$scope.columns = [
{ field: 'name', displayName: 'First Name', width: 300},
{ field: 'lastname', displayName: 'Last Name', width: 300 },
{ field: 'email', displayName: 'Email', width: 300 },
{ field: 'company', displayName: 'Company', width: '50%' }
];
//Options for displaying the grid
$scope.gridOptions = {
data: 'myData',
enableCellEditOnFocus: false,
pagingPageSizes: [2, 5, 7],
pagingPageSize: 5,
enableSorting: true,
enableGridMenu: true,
columnDefs: $scope.columns,
onRegisterApi: function (gridApi) {
$scope.gridApi = gridApi;
//var cellTemplate = '<button class="btn primary" ng-click="getExternalScopes().showMe(rowCol.row.entity)">Edit</button>'; //'ui-grid/selectionRowHeader'; // you could use your own template here
//$scope.gridApi.core.addRowHeaderColumn({ name: 'rowHeaderCol', displayName: '', width: 50, pinnedLeft: true, cellTemplate: cellTemplate });
gridApi.rowEdit.on.saveRow($scope, $scope.saveRow);
}
};
// Save row data on edit 1 - TESTING
$scope.saveRow = function (rowEntity) {
// create a fake promise - normally you'd use the promise returned by $http or $resource
var promise = $http.post("Webapps/Home/SaveRow");
$scope.gridApi.rowEdit.setSavePromise($scope.gridApi.grid, rowEntity, promise.promise);
console.log(rowEntity);
// fake a delay of 3 seconds whilst the save occurs, return error if gender is "male"
$interval(function () {
if (rowEntity.lastname === ' ') {
promise.reject();
} else {
promise.resolve();
}
}, 3000, 1);
};
}]); // End of MyCtrl
我的问题是在问候了$ scope.saveRow方法。我看过了的文档 rel=\"nofollow\">并试图寻找对谷歌（没有太多出那里UI网），但我还是打了死胡同因为我跟这个有点经验不足，我不知道如何code此妥善承诺。
My question is in regards to the $scope.saveRow method. I've looked over the documentation here and tried searching on google (not much out there for ui-grid) but I'm still hitting a dead end as I'm a bit inexperienced with this and I'm not sure how to code this properly with promises.
有将运行这背后，将处理数据推到前端和保存表编辑一个SQLServer数据库的MVC应用程序。显然，我想要做的就是有这个$ scope.saveRow功能正常的rowEnttiy数据发送回我的MVC应用程序，但同样，我在为如何code中的功能丧失。包括本例中的假货承诺是不够的，我要得到什么，我需要做的把握，显然。我最初尝试以下操作：
There will be an MVC app running behind this which will handle pushing the data to the front end and saving table edits to a SQLServer db. Obviously what I'd like to do is have this $scope.saveRow function properly send the rowEnttiy data back to my MVC app but, again, I'm at a loss for how to code the function. The "fake" promises included in the example aren't enough for me to get a grasp on what I need to do, apparently. I initially tried the following:
$scope.saveRow = function (rowEntity) {
try {
// Need actual URL for post...controller has to accept 'row'
$http.post("Webapps/Home/SaveRow", { row: rowEntity }).success(function (data, status, headers, config) {
console.log("post success");
console.log(rowEntity);
}).error(function (data, status, headers, config) {
console.log("post failure");
console.log(rowEntity);
});
} catch (e) {
alert("Something went wrong");
}
};
但这只是抛出我的控制台的异常时提出的saveRow事件未归还的承诺。
but this only throws an exception in my console that a promise was not returned when the saveRow event is raised.
推荐答案
您通常会做的承诺/ API调用在一个单独的存储库中，但基本上code你正在寻找的是这样的：
You would normally do the promise/api call in a separate repository, but basically the code you are looking for is something like this:
$scope.saveRow = function( rowEntity ) {
var promise = $scope.someRepositoryFunction(rowEntity);
$scope.gridApi.rowEdit.setSavePromise($scope.gridApi.grid, rowEntity, promise);
// fake a delay of 3 seconds whilst the save occurs, return error if gender is "male"
//$interval( function() {
// if (rowEntity.firstName === 'male' ){
// promise.reject();
// } else {
// promise.resolve();
// }
//}, 3000, 1);
};
$scope.someRepositoryFunction = function(row) {
return $http.put('/Home/UpdateRow',row);
}
