我正在尝试显示响应JSON的值：
$http.get('index.php/administration/UsersAdminController/getAllDepartments')
.then(function(response) {
if(response.data.message == "success") {
$scope.departments = response.data.data;
}
});
当我使用ng-repeat时，JSON显示如下：
<div ng-repeat="values in departments">
{{values}}
</div>
告诉我这个：
{"id":1,"name":"Computación","description":"Departamento","positions":[
{"id":1,"name":"Estudiante","description":"Yo soy un estudiante"},
{"id":2,"name":"Profesor","description":"Educador"}]}
{"id":2,"name":"Quimica","description":"Departamento de quimica","positions":[
{"id":3,"name":"Quimico","description":"Soy un quimico"},
{"id":4,"name":"Farmaco","description":"Farmaco del dpto de quimica"}]}
我需要的是，现在，它是在选择中将名称显示为选项。
我已经尝试过各种方式，使用ng-repeat和ng-options并且无法工作。当我点击选择没有任何反应。
<select ng-model="newDepartment" ng-options="key as value for (key , valu) in departments"></select>
<select ng-model="ciudadElegida" ng-options="departmet as department.name for department in departments"></select>
我认为这是ng-options值的一部分，但我无法弄明白。
Pd：我已经用
实现了脚本$('select').material_select();
编辑：回应贾斯汀赫特
感谢您的帮助！我使用$scope.departments = JSON.stringify(response.data.data);然后显示部门console.log($scope.departments)
告诉我这个：
[{"id":1,"name":"Computación","description":"Departamento","positions":[{"id":1,"name":"Estudiante","description":"Yo soy un estudiante"},{"id":2,"name":"Profesor","description":"Educador"}]},{"id":2,"name":"Quimica","description":"Departamento de quimica","positions":[{"id":3,"name":"Quimico","description":"Soy un quimico"},{"id":4,"name":"Farmaco","description":"Farmaco del dpto de quimica"}]}]
这正是你对部门的意义，所以应该工作，但事实并非如此。再次，当我点击选择选项nathing发生。我开始严格地讨论可能导致这个问题的物化导入的事实。
编辑2：解决方案
问题始终是物化和角度js之间不兼容。
Angular不允许在实例化后修改项目。每次更新select函数时，Materialise都需要$('select').material_select();
解决方案是添加一个带有指令的文件，这样每次编辑select时都会执行materialize函数和angular的重新编译。
在/js文件夹中保存带有以下内容的.js脚本：

你应该首先解析JSON：
$http.get('index.php/administration/UsersAdminController/getAllDepartments')
.then(function(response) {
if(response.data.message == "success") {
$scope.departments = JSON.parse(response.data.data);
}
});
使用它来测试ng-options（取自上面的示例输出）：
JSON.parse(JSON.stringify([{"id":1,"name":"Computación","description":"Departamento","positions":[
{"id":1,"name":"Estudiante","description":"Yo soy un estudiante"},
{"id":2,"name":"Profesor","description":"Educador"}]},
{"id":2,"name":"Quimica","description":"Departamento de quimica","positions":[
{"id":3,"name":"Quimico","description":"Soy un quimico"},
{"id":4,"name":"Farmaco","description":"Farmaco del dpto de quimica"}]}]))
这告诉我你服务器响应的JSON对象格式不正确。

由于您解决了来自API错误的数据问题，现在您遇到了未在视图中显示的项目的问题，所以我们开始：
首先，您的HTML中存在一些错误，我已对其进行了更正，您可以查看以下内容：
您没有正确设置value名称：
<select ng-model="newDepartment" ng-options="key as value for (key , valu) in departments"></select>
它也应该是：key as value.name* instead of键作为值`;
departmet应为部门：
<select ng-model="ciudadElegida" ng-options="departmet as department.name for department in departments"></select>
