如何在角度ui网格中显示从json到ui-grid的数据

Question

我从django得到这个json，我想用角度ui-grid显示这个，但是我收到了错误：

Error: colDef.name or colDef.field property is required
preprocessColDef@http://127.0.0.1:8000/static/buddy/js/ui-grid.js:3771:1

我只想显示“字段”中的属性

json是：

[{"fields": {"joiningtime": null, "boozprofileId": 1, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 1}, {"fields": {"joiningtime": null, "boozprofileId": 1, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 2}, {"fields": {"joiningtime": "2015-10-18T15:53:58.243Z", "boozprofileId": 12, "userId": 3, "likeStatus": true}, "model": "buddy.guestentry", "pk": 3}, {"fields": {"joiningtime": "2015-10-18T15:54:24.055Z", "boozprofileId": 8, "userId": 3, "likeStatus": true}, "model": "buddy.guestentry", "pk": 4}, {"fields": {"joiningtime": null, "boozprofileId": 3, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 5}, {"fields": {"joiningtime": null, "boozprofileId": 3, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 6}, {"fields": {"joiningtime": null, "boozprofileId": 3, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 7}, {"fields": {"joiningtime": null, "boozprofileId": 3, "userId": 1, "likeStatus": true}, "model": "buddy.guestentry", "pk": 8}]

Answer 1

您收到的错误表明您没有为UI Grid定义列定义，或者可能没有正确定义它们。 只需将嵌套fields属性称为fields.<attributeName> ：

//the JSON from above 
$scope.gridOptions.data = [{"fields": {"joiningtime": null, "boozprofileId": ....}];

$scope.gridOptions.columnDefs = [
   {name: 'fields.joiningtime' }, 
   {name: 'fields.boozprofileId' }, 
   {name: 'fields.userId' },
   {name: 'fields.likeStatus' } 
];

记住要瞄准正确的控制器。 你有IndexCtrl和ajax ：

<div ng-controller="ajax">
   <div ui-grid="gridOptions" ui-grid-cellNav class="grid"></div>
</div>

Answer 2

以防大卫的答案对你没有帮助：

尝试删除

$scope.gridOptions.data = [{"fields": {"joiningtime": null, "boozprofileId": ....}];

$scope.gridOptions.columnDefs = [
   {name: 'fields.joiningtime' }, 
   {name: 'fields.boozprofileId' }, 
   {name: 'fields.userId' },
   {name: 'fields.likeStatus' } 
];

从JSON received之后放入控制器功能启动。

我的意思是在开始时初始化它，然后在收到JSON response时更新data

$scope.gridOptions.data = response.data
