angularjs – 如何使用ng-messages显示Checkbox集和Radio set的

我一直在尝试验证Checkbox set和Radio set并使用ng-messages指令显示错误消息但是它没有按预期工作. ng-messages根本不显示错误消息.我正在使用html文件填充错误消息.在解决错误之前,我的表单中将禁用提交按钮.

如何在以下情况下显示Checkbox集和Radio set的错误消息：

>收音机中未选择一个选项？
>复选框设置中未选择至少一个选项？
>缩放检查复选框集,以便我们检查至少2个或更多,检查等？

这是我的表格：

<form name="userForm" ng-submit="submitForm()" novalidate>
    <div class="form-group" ng-class="{ 'has-error' : userForm.subscribe.$invalid && !userForm.subscribe.$touched }">
        <label class="checkbox-inline">
            <input type="checkbox" id="subscribe1" value="option1" name="subscribe[]" ng-model="user.subscribe" required> 1
        </label>
        <label class="checkbox-inline">
            <input type="checkbox" id="subscribe2" value="option2" name="subscribe[]" ng-model="user.subscribe" required> 2
        </label>
        <label class="checkbox-inline">
            <input type="checkbox" id="subscribe3" value="option3" name="subscribe[]" ng-model="user.subscribe" required> 3
        </label>

        <div class="help-block" ng-messages="userForm.subscribe.$error" ng-show="userForm.subscribe.$invalid">
            <div ng-messages-include="home/messages.html"></div>
        </div>
    </div>

    <div class="form-group" ng-class="{ 'has-error' : userForm.gender.$invalid && !userForm.gender.$touched }">
        <div class="radio">
            <label>
                <input type="radio" name="gender" value="male" ng-model="user.gender" />
                male
            </label>
        </div>
        <div class="radio">
            <label>
                <input type="radio" name="gender" value="female" ng-model="user.gender" />
                female
            </label>
        </div>

        <div class="help-block" ng-messages="userForm.gender.$error" ng-show="userForm.gender.$invalid">
            <div ng-messages-include="home/messages.html"></div>
        </div>
    </div>
    <button type="submit" class="btn btn-primary btn-success " ng-disabled="userForm.$invalid">Submit</button>
</form>

messages.html

<span ng-message="required">This field is required</span>
<span ng-message="minlength">This field is too short</span>
<span ng-message="maxlength">This field is too long</span>
<span ng-message="required">This field is required</span>
<span ng-message="email">This needs to be a valid email</span>

controller.js

angular.module('myApp',['ngRoute','ngAnimate','ngMessages']);

angular
    .module('myApp')
    .controller('HomeCtrl',HomeCtrl);

HomeCtrl.$inject = ['$scope'];

function HomeCtrl($scope) {
    $scope.userForm = {};
}

付款复选框设置：
