我正在构建一个Reddit克隆。到目前为止,您可以在发布的链接上添加链接,upvote / down投票和评论/删除评论。您必须通过Twitter登录才能添加评论或帖子。
我面临的一个重大问题是,当帖子发表评论时,如果您重新加载网站,则不会显示。您必须添加新评论才能查看已存在的评论。下一个重要问题是,如果您添加新帖子,它会自动继承先前评论过的帖子中的评论,即使这些评论不在Firebase服务器上的帖子数据中。
如果您对新帖子发表评论,则会导致所有其他帖子的评论继承新帖子的新评论。
这是源代码。

答案 0 :(得分:1)
您只在comments
上存储了一个$scope
数组。
然后在您的模板中,您为post
上的ng-repeat
内的每个posts
循环遍历此一个数组,因此两个帖子都是相同的。您需要循环遍历comments
特定于post
的{{1}}。像这样:
<div class="panel panel-default" ng-repeat="comment in post.comments">
注意post.comments
。
