Question

我似乎遇到了RPush和Houston的问题。

这或多或少是我的控制器的样子......

def create
    if authenticate_user
        post = Post.find_by_id(params[:post_id])
        if post
            comment = post.comments.new(comment_params.merge(user_id: params[:user_id]))

            Comment.transaction do
                if (comment.save)
                    apns_file = File.join(Rails.root, "APNSCert.pem")
                    app = Rpush::Apns::App.new
                    app.name = "My App"
                    app.certificate = File.read(apns_file)
                    app.environment = "sandbox" # APNs environment.
                    app.password = ENV["apns_certificate_password"] #figaro
                    app.connections = 1
                    app.save!

                    #SEND Push notification to the user who made the original post
                    post_user = User.find(post.user_id)
                    comment_user = User.find(comment.user_id)

                    if post_user && comment_user
                        rememeber_tokens_for_user = RememberToken.where("user_id = ?", post_user.id)
                        if rememeber_tokens_for_user.size > 0
                            rememeber_tokens_for_user.each do |remember_token|
                                # Create a notification that alerts a message to the user, plays a sound, and sets the badge on the app

                                alert = comment_user.name + ": " + comment.comment_text
                                if alert.length > 50
                                    alert = alert[0..46] + "..."
                                end

                                n = Rpush::Apns::Notification.new
                                n.app = Rpush::Apns::App.find_by_name("My App")
                                n.device_token = remember_token.device_token
                                n.alert = alert
                                n.data = { foo: "bar" }
                                n.save!

看来myoku上的服务器在app.save!行ActiveRecord::RecordInvalid (Validation failed: Name has already been taken):上收到错误。

我只不过是铁轨的中间人，所以任何帮助都会受到赞赏。我想把代码的'app'变量部分放到一个单独的类中，这个类只调用一次或类似东西，类似于objective-c中的单例？它显然不喜欢当它被一个不同的用户POST到这个资源时访问，这是我收到这个错误的时候。

我应该去刺激Grocer，因为我似乎无法让休斯顿或RPush工作？

Answer 1

您绝对不需要为每个应用多次执行APN设置。这正是你遇到问题的原因。

Answer 2

只有在没有创建应用时才插入支票来创建应用：

if !Rpush::Gcm::App.find_by_name("My App")
    app.name = "My App"
    app.certificate = File.read(apns_file)
    app.environment = "sandbox" # APNs environment.
    app.password = ENV["apns_certificate_password"] #figaro
    app.connections = 1
    app.save!
end

如何使用Rails gems RPush或Houston发送推送通知？
