数据表:自定义响应处理 [英] DataTables: Custom Response Handling
问题描述
我开始工作 AngularJS
和的 数据表
,并怀疑它是否是可以自定义的响应数据表
期待。该数据表插件目前的期望是这样的:
I started working on AngularJS
and DataTables
and wonder whether it is possible to customize the response DataTables
is expecting. The current expectation of the DataTables plugin is something like this:
{
"draw": 1,
"recordsTotal": 57,
"recordsFiltered": 5,
"data": [...]
}
在服务器端,该API的正在由 Django的tastypie处理
On the server end, the API's are being handled by django-tastypie
从服务器的响应是:
{
meta: {
limit: 20,
next: null,
offset: 0,
previous: null,
total_count: 2
},
objects: [...]
}
那么,有没有一种方法来调整数据表插件接受/图这种反应,不然我就必须找到一种方法来预期字段添加到API?
So, is there a way to tweak Datatables Plugin to accept/map this response, or I'll have to find a way to add expected fields to the api?
到目前为止,我已经做到了这一点:
So far I've done this:
var deptTable = angular.element('#deptManagementTable').DataTable({
processing: true,
serverSide: true,
pagingType: "simple_numbers",
ajax: {
url: "/client/api/v1/departments/",
data: function(d) {
d.limit = d.length;
d.offset = d.start;
d.dept_name__icontains = d.search.value;
},
dataSrc: function(json) {
for (var i=0, len=json.objects.length ; i<len ; i++) {
json.objects[i].DT_RowId = json.objects[i].dept_id;
}
return json.objects;
}
},
aLengthMenu: [
[5, 25, 50, 100],
[5, 25, 50, 100]
],
iDisplayLength: 5,
columns: [
{
data: "dept_name"
},
{
data: "dept_created_on",
render: function ( data, type, full, meta ) {
var dateCreated = new Date(data);
dateCreated = dateCreated.toLocaleDateString();
return dateCreated;
}
}
]
});
任何帮助将AP preciated。
Any help will be appreciated.
在此先感谢:)
推荐答案
您可以通过一个函数的数据表 AJAX
选项,这会给你完全控制如何获取并传递到数据表之前映射数据。
You can pass a function to the DataTables ajax
option, this will give you full control over how to fetch and map the data before passing it to DataTables.
.DataTable({
serverSide: true,
ajax: function(data, callback, settings) {
// make a regular ajax request using data.start and data.length
$.get('/client/api/v1/departments/', {
limit: data.length,
offset: data.start,
dept_name__icontains: data.search.value
}, function(res) {
// map your server's response to the DataTables format and pass it to
// DataTables' callback
callback({
recordsTotal: res.meta.total_count,
recordsFiltered: res.meta.total_count,
data: res.objects
});
});
}
});
解决方法上面已经测试过使用jQuery 数据表 1.10.4。
由于这个问题被打上角,这里是使用角的DataTable 的一个解决方案。
As this question is tagged with Angular, here's a solution for those using angular-datatables.
<div ng-controller="testCtrl">
<table datatable dt-options="dtOptions" dt-columns="dtColumns" class="row-border hover"></table>
</div>
.controller('testCtrl', function($scope, $http, DTOptionsBuilder, DTColumnBuilder) {
$scope.dtOptions = DTOptionsBuilder.newOptions()
.withOption('serverSide', true)
.withOption('ajax', function(data, callback, settings) {
// make an ajax request using data.start and data.length
$http.get('/client/api/v1/departments/', {
limit: data.length,
offset: data.start,
dept_name__icontains: data.search.value
}).success(function(res) {
// map your server's response to the DataTables format and pass it to
// DataTables' callback
callback({
recordsTotal: res.meta.total_count,
recordsFiltered: res.meta.total_count,
data: res.objects
});
});
})
.withDataProp('data'); // IMPORTANT¹
$scope.dtColumns = [
// your column definitions here
];
});
解决方法上面已经过测试角数据表0.3.0 +数据表1.10.4。
The solution above has been tested with angular-datatables 0.3.0 + DataTables 1.10.4.
¹这里要注意的重要组成部分,是该角的DataTable解决方案需要 .withDataProp('数据')
来工作,而纯jQuery的数据表解决方案不具备一个数据:数据
选项
¹ The important part to note here is that the angular-datatables solution requires .withDataProp('data')
to work, while the pure jQuery DataTables solution does not have a data: 'data'
option.
