使用模态jhipster编辑对象

Question

我使用JHipster来创建我的项目，并且最近一帆风顺。但是，我遇到了在main.html上编辑对象的问题。当我在路由器指向的posts.html页面上时，我能够成功编辑帖子，但是我无法使用main.html上完全相同的代码执行此操作。我可以在我的主页面上调用postController中的信息，并且它可以充分显示。但是，我无法使我的数据显示在模态弹出窗口中。我知道控制器正在接收信息，因为我的console.log（$ scope.post）返回了我想要编辑的对象。但是，该信息不会传输到我的模态。任何帮助表示赞赏。

调用编辑的按钮：

//inside postController and an ng-repeat of posts calling update function
<button class="btn btn-primary btn-xs" type="submit" ng-click="update(post.id)" class="btn">
    <span class="glyphicon glyphicon-pencil"></span> Edit
</button>

实际模态代码：

<div ng-controller="postController">
            <textarea class="form-control" rows="3" placeholder="Status update here..." data-toggle="modal" data-target="#savePostModal" ng-click="clear()"></textarea>
            <div class="modal fade" id="savePostModal" tabindex="-1" role="dialog" aria-labelledby="myPostLabel" aria-hidden="true">
                <div class="modal-dialog">
                    <div class="modal-content">
                        <form name="form" role="form" novalidate class="ng-scope ng-invalid ng-invalid-required ng-dirty ng-valid-minlength" ng-submit="create()">

                            <div class="modal-header">
                                <button type="button" class="close" data-dismiss="modal" aria-hidden="true" ng-click="clear()">&times;</button>
                                <h4 class="modal-title" id="myPostLabel">Create or edit a Post</h4>
                            </div>
                            <div class="modal-body">
                                <div class="form-group">
                                    <label>ID</label>
                                    <input type="text" class="form-control" name="id" ng-model="post.id" readonly>
                                </div>

                                <div class="form-group">
                                    <label>Title</label>
                                    <input type="text" class="form-control" name="test" placeholder="Title your post..." ng-model="post.name" ng-minlength=1 required>
                                </div>

                                <div class="form-group">
                                    <label>Author</label>
                                    <input type="text" class="form-control" name="test" placeholder="Temporary Field..." ng-model="post.author" ng-minlength=1 required>
                                </div>

                                <div class="form-group">
                                    <label>Text</label>
                                    <textarea rows="8" placeholder="Status update here..." class="form-control" type="text" name="test" ng-model="post.text" ng-minlength=1 required></textarea>
                                </div>
                            </div>
                            <div class="modal-footer">
                                <button type="button" class="btn btn-default" data-dismiss="modal" ng-click="clear()">
                                    <span class="glyphicon glyphicon-ban-circle"></span> Cancel
                                </button>
                                <button type="submit" ng-disabled="form.$invalid" class="btn btn-primary">
                                    <span class="glyphicon glyphicon-save"></span> Save
                                </button>
                            </div>
                        </form>
                    </div>
                </div>
            </div>
        </div>

更新功能

$scope.update = function (id) {
        $scope.post = Post.get({id: id});
        $('#savePostModal').modal('show');
    };

我知道它已成功调用此get函数，但$ scope.post中的数据未被使用。

事实证明，为了使模态工作，它必须与打印按钮的文本位于同一个controller-div中。我很确定这是因为如果div不同，控制器上的范围会有所不同。另外，没有第二个具有相同名称的模态用于测试，因为它将不可避免地因为功能混淆而无法使用。

<div id="toBeUpdated" ng-controller="postController">
   <div class="modal fade" id="savePostModal" tabindex="-1" role="dialog" aria-labelledby="myPostLabel" aria-hidden="true">
      <div class="modal-dialog">
         <div class="modal-content">
            <form name="form" role="form" novalidate class="ng-scope ng-invalid ng-invalid-required ng-dirty ng-valid-minlength" ng-submit="createMob()">
