How to remove deleted row in ng-table - angularjs

Question

I have a grid developed using ng-table and I need to remove selected item from grid table after removing from server-side. Already tried to call the grid loading ajax again, but it's not working.
My Controller,
app.controller('blockController', function($scope, $filter, $q, ngTableParams, $sce, Block) {
// Fetch data from server using RESTful API
$scope.load = function() {
// load serverside data using http resource service
Block.get({}, function (response) { // success
$scope.results = response.data;
var data = response.data; // store result to variable
// Start ng-table with pagination
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 10 // count per page
}, {
total: data.length, // length of data
getData: function($defer, params) {
// use build-in angular filter
var orderedData = params.sorting() ? $filter('orderBy')(data, params.orderBy()) : data;
orderedData = params.filter() ? $filter('filter')(orderedData, params.filter()) : orderedData;
params.total(orderedData.length); // set total for recalc pagination
$defer.resolve($scope.blocks = orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
}
});
// un-check all check boxes
$scope.checkboxes = { 'checked': false, items: {} };
// watch for check all checkbox
$scope.$watch('checkboxes.checked', function(value) {
angular.forEach($scope.blocks, function(item) {
if (angular.isDefined(item.id)) {
$scope.checkboxes.items[item.id] = value;
}
});
});
// watch for data checkboxes
$scope.$watch('checkboxes.items', function(values) {
if (!$scope.blocks) {
return;
}
var checked = 0, unchecked = 0,
total = $scope.blocks.length;
angular.forEach($scope.blocks, function(item) {
checked += ($scope.checkboxes.items[item.id]) || 0;
unchecked += (!$scope.checkboxes.items[item.id]) || 0;
});
if ((unchecked == 0) || (checked == 0)) {
$scope.checkboxes.checked = (checked == total);
}
// grayed checkbox
angular.element(document.getElementById("select_all")).prop("indeterminate", (checked != 0 && unchecked != 0));
}, true);
}, function (error) { // error
$scope.results = [];
// error message display here
});
}
// Call REST API
$scope.load();
/*
|------------------------------
| Delete selected items
|------------------------------
*/
$scope.delete = function() {
var items = [];
// loop through all checkboxes
angular.forEach($scope.blocks, function(item, key) {
if($scope.checkboxes.items[item.id]) {
items.push(item.id); // push checked items to array
}
});
// if at least one item checked
if(items.length > 0) {
// confirm delete
bootbox.confirm("Are you sure to delete this data?", function(result) {
if(result==true) {
for (var i = 0; i < items.length; i++) {
// delete using $http resopurce
Block.delete({id: items[i]}, function (response) { // success
// remove the deleted item from grid here
// show message
}, function (error) { // error
// error message display here
});
}
}
});
}
}; // delete
}); // end controller
HTML Table,
<!-- data table grid -->
<table cellpadding="0" cellspacing="0" border="0" class="table table-striped table-bordered" ng-table="tableParams" show-filter="true">

Answer 1

You should remove the deleted item from the data collection once the server confirms the deletion.
You can do this manually from within the delete success callback instead of just reloading the complete collection (which is theoretically valid as well but will often be slower).
Then after removing the item from the collection, call the tableParams.reload() method to reload the table so the change is reflected in the table.
You can find a working example of the reload() method right here: http://plnkr.co/edit/QXbrbz?p=info
Hope that helps!

This is working for me:
$scope.deleteEntity = function (entity) {
bootbox.confirm("Are you sure you want to delete this entity ?", function (confirmation) {
if (confirmation) {
$http.delete("/url/" + entity._id)
.success(function (data) {
if (data.status == 1) {
var index = _.indexOf($scope.data, entity);
$scope.data.splice(index, 1);
$scope.tableParams.reload();
} else {
}
});
}
}
);
};

In version 1x of ng-table the following code works. In this example I'm using the MyController as vm approach and user is a $resource class object:
this.removeUser = function (user,i) {
user.$remove().then(function () {
this.tableParams.data.splice(i, 1);
}, function () {
// handle failure
});
});
When called in your HTML table, be sure to pass in $index as the second parameter, eg:
<button class="btn btn-danger btn-xs" ng-click="vm.removeUser(user, $index)" title="Delete User">
<i class="glyphicon glyphicon-trash"></i>
</button>
No need to call tableParams.reload or reload data from the server.
