Question

我在Google App Engine（python）上部署了一个角度应用。

每当我尝试使用{{}}表示法访问View上的控制器变量时，没有任何反应。

控制器

$scope.abc ="ABC"

观看视频

<h2>{{abc}}</h2>

如果我在没有app引擎的情况下在本地运行我的应用程序，这都有效但在部署后，相同的代码不起作用。

我用谷歌搜索了但没有得到任何东西。 {{}}有什么问题？

Answer 1

您必须替换{{}}代码

因为python django也使用它 var myApp = angular.module（＆＃39; DemoProject＆＃39;，[]）;

    myApp.config(function($interpolateProvider) {
        $interpolateProvider.startSymbol('{$');
        $interpolateProvider.endSymbol('$}');
        });
    myApp.run(function ($rootScope) {

    });

使用它{$ $}将起作用

Answer 2

与angular和python / webapp的{{}}表达式存在冲突。所以我用$ interpolateProvider用////

来改变{{}}
