Answer 1

嘗試修改您的JSON迴應是這樣的：

[{"id":1,"name":"This is first then","description":"This is first then","created_at":"2014-10-08T10:37:08.208Z"},{"id":2,"name":"Second Themes","description":"Second Themes","created_at":"2014-10-08T11:28:54.900Z"},{"id":4,"name":"4th theme","description":"4th theme","created_at":"2014-10-09T05:13:35.605Z"}] 

您可以從軌道做主題/ index.json

object false 
child(@themes => :themes) do 
    extends "themes/show" 
end 

修改爲：

object @themes 
attributes :id, :name, :description, :created_at 

在 資源

，並isArray: true

$scope.obj = {"themes":[{"id":1,"name":"This is first then","description":"This is first then"},{"id":2,"name":"Second Themes","description":"Second Themes"},{"id":3,"name":"This is $th theme","description":"This is $th theme"}]} 

<tr ng-show="obj.themes.length > 0" ng-repeat="theme in obj.themes"> 
    <td>{{theme.name}}</td> 
    <td>{{theme.description}}</td> 
</tr>
