在rails中向用户发表评论通知？ [英] Comment notification to users in rails?

问题描述

我的webapp有注册用户，它有文章，博客文章，闲话太。
对于所有这些资源，我有一个多态的注释模型，如下所示。

my webapp has registered users and it has articles, blog posts, gossips too. For all these resources I've a polymorphic Comment model which is listed below.

id  content         commentable_id  commentable_type   user_id  created_at  updated_at
1   Frist comment   2               Article            1        ....
2   Second comment  3               Post               2        .....

因此，对于每个可注释的资源，我在注释资源的底部有一个注释表单，供用户评论。
我想要一个复选框，当提交评论时选中，用户应该收到一个通知，无论是在收件箱或电子邮件，因为我们已经在用户注册，以后其他新的评论时添加。

So for each commentable resource, I've a comment form at the bottom of the commentable resource for users to comment. I want a checkbox, when checked while submitting the comment, the users should receive a notification, be it in Inbox or email since we already have it on user signup, when other new comments are added later.

我想有一些模型像通知，我可以存储commentable_type，commentable_id和user_id（如果有任何新的评论创建与匹配的可评论和用户？

I want to have some model like Notifications where I could store the commentable_type, commentable_id and user_id (to whom the notification should be sent if there is any new comment created with the matching commentable and user?

如何实现注释和通知之间的关联？对于检查部分，如果有任何一个订阅特定的可注释资源，则创建一个CommentObserver with after_create hook如果有任何匹配的记录，则初始化搜索并发送通知。

How can I implement the association between Comment and Notification? For the checking part if there is any one subscribe to the particular commentable resource is create a CommentObserver with after_create hook to initialize the search and send notifications if there is any matching record.

但是我很困惑什么关联，模型，控制器和视图来完成这个？注释模型已经是多态的，我可以创建Notification模型作为多态吗？

But I'm confused what the association, model, controller and views would look like to accomplish this? Since the comment model is already polymorphic, can I create the Notification model as polymorphic too??

推荐答案

插入。
创建数据库表以存储帖子的用户通知订阅。然后，每次创建注释时，查询数据库并使用 ActionMailer a>到所有用户的地址。

You can easily accomplish this without a plugin. Create a database table to store User notification subscriptions for posts. Then, each time you create a comment, query the database and send an email using ActionMailer to all users' address.
