我想在我的rails应用程序中使用私有pub gem。我用railscast 316实现
rails g private_pub:install
之后
我的private_pub.yml文件:
development:
server: "http://0.0.0.0:9292/faye"
secret_token: "secret"
test:
server: "http://0.0.0.0:9292/faye"
secret_token: "secret"
production:
server: "http://0.0.0.0/faye"
secret_token: "98ec77eb7077c9899dc53f003abc4d6a0170512a57feab126ed5a32b114e3613"
signature_expiration: 3600 # one hour
我的private_pub.ru文件
# Run with: rackup private_pub.ru -s thin -E production
require "bundler/setup"
require "yaml"
require "faye"
require "private_pub"
Faye::WebSocket.load_adapter('thin')
PrivatePub.load_config(File.expand_path("../config/private_pub.yml", __FILE__), ENV["RAILS_ENV"] || "development")
run PrivatePub.faye_app
Faye::Logging.log_level = :debug
Faye.logger = lambda { |m| puts m }
我的索引文件
<h1>Chat</h1>
<ul id="chat">
<%= render @mesajlar %>
</ul>
<%= form_for Mesaj.new, remote: true do |f| %>
<%= f.text_field :icerik %>
<%= f.submit "Send" %>
<% end %>
<%= subscribe_to "/mesajlar/new" %>
控制器文件:
def create
params[:mesaj][:gonderen_id]= current_kullanici.id
@mesaj = Mesaj.create!(params[:mesaj])
PrivatePub.publish_to("/mesajlar/new", "alert('#{@mesaj.icerik}');")
end
我将//= require private_pub
添加到application.js文件
页面初始化后,我在firebug上收到以下错误:
**PrivatePub is not defined**
at
<script type="text/javascript">PrivatePub.sign({"server":"http://0.0.0.0:9292","timestamp":1363853952047,"channel":"/mesajlar/new","signature":"7bf74474796412b524b6c6c8849c50cb245ce92d"});</script>
</div>
Rails日志和RAILS_ENV=production bundle exec rackup private_pub.ru -s thin -E production
命令日志中没有输出
我搜索过但没有找到解决方案。
问题出在哪里?
答案 0 :(得分:6)
我发现问题,我会编写解决方案,因为其他任何人都应该收到此错误:
我的javascripts放在底部,所以
<%= subscribe_to "/mesajlar/new" %> line calling before private_pub.js is loaded.
所以, 在索引文件
<% content_for :bottom do %>
<%= subscribe_to "/mesajlar/new" %>
<% end %>
可以解决这个问题。

我想您忘记将private_pub.js
添加到application.js
:
//= require private_pub
