python - Django 和 knockoutjs (foreach)

Question

在视图中：

 posts = Posts.objects.filter(...)
        template = loader.get_template('...')
        context = Context({
            'comments': comments,
            })
        return HttpResponseForbidden(template.render(RequestContext(request, context)))

在模板中：

 <script type="text/javascript">
    head.js('...');
    head.ready(function() {
        $(document).ready(function() {
            postModel = new postModel({
                posts: '{{ posts }}'
            });
            ko.applyBindings(commentModel, $('#posts')[0]); 

        });
    });
    </script>
<ul data-bind="foreach: comments">
....
</ul>

在 post.js 中

self.comments = ko.observableArray(ko.utils.parseJson(config.comments)); //error: Uncaught SyntaxError: Unexpected token & 
self.comments = ko.observableArray(config.comments); //error: Uncaught TypeError: Cannot use 'in' operator to search for 'length' in

如何转换数据类型？

{{ posts}}
 [<Post: un posts!>, <Post: deux posts!>] to [{id:1, content:'un posts' etc},{...}]

Answer 1

在脚本中：

postModel = new postModel({
                posts: '{{ posts.fields }}'
            });
            ko.applyBindings(postModel, $('#post')[0]);
