Question

所以我试图从控制器中的动作中获取一些信息。

目前的行动如下：

def index
        @users = User.all

        respond_to do |format|
            format.html
            format.json { render json: @users }
        end
end

此索引页面设置为routes.rb

中的根目录

现在，这就是我的AngularJs控制器的样子，从我试图获取信息的位置：

@test.controller 'TestCtrl', ['$scope', '$location', '$http', ($scope, $location, $http) ->
    $scope.data = []

    $http.get('/')
    .success (data) =>
        $scope.data = data
        console.log($scope.data)
    .error (data) ->
        console.log('error!')
]

当我加载根页面时，我只在Javascript控制台日志中将整个页面加载为html。

所以我在这里遗漏了一些需要做的事情，以便在json中为我的AngularJs控制器响应动作index吗？

我通过不对'/'路由进行查询而是向'/users.json'进行查询来解决问题。即使你做了这样的事情：'/.json'，它也行不通。

使用Angular＆＃39; $ http时无法从控制器获取json信息
