在控制器中创建了一个新的Active Record模型，但除非我刷新，否则它不会显示在视图上(Created a new Active Record model in controller but it doesn't show up on view unless I refresh)

在控制器中，特别是编辑操作，我以与此相同的方式创建了一个新的Active Record模型：

@newPost = Post.new @newPost.update_attribute(:title, @some_title) @newPost.update_attribute(:completed, 0) @newPost.save @all_user_posts = @user.posts

现在，当我尝试调用@all_user_posts并在视图中显示它时，除非我刷新页面，否则它不会显示。 这里发生了什么，是否有更好的方法来解决这个问题，以便我可以在创建新帖子时立即显示新帖子而无需刷新页面？

In the controller, specifically the edit action, I created a new Active Record model in the same manner as this:

@newPost = Post.new @newPost.update_attribute(:title, @some_title) @newPost.update_attribute(:completed, 0) @newPost.save @all_user_posts = @user.posts

Now, when I try to call on @all_user_posts and show it in the view, it doesn't show up unless I refresh the page. What's going on here and is there a better way to approach this so that I can show the new posts as soon as I create them without having to refresh the page?

最满意答案

我想我其实可以这样做：

@all_user_posts = Post.where("user_id =?", @user.id)

但是，有人还能解释为什么会这样吗？

I figured I can actually just do this:

@all_user_posts = Post.where("user_id =?", @user.id)

But, could someone still explain why it happens?
