i want show attributes "fields"

the json is:

[{"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}]

the error receive indicates not have defined column definitions ui grid, or perhaps not have defined them properly. refer nested fields attributes fields.<attributename> :

//the json above  $scope.gridoptions.data = [{"fields": {"joiningtime": null, "boozprofileid": ....}];  $scope.gridoptions.columndefs = [    {name: 'fields.joiningtime' },     {name: 'fields.boozprofileid' },     {name: 'fields.userid' },    {name: 'fields.likestatus' }  ];

remember target right controller. have both indexctrl , ajax :

<div ng-controller="ajax">    <div ui-grid="gridoptions" ui-grid-cellnav class="grid"></div> </div>
