Websocket 控制器未在 Rails 开发环境中自动加载
Posted
技术标签:
【中文标题】Websocket 控制器未在 Rails 开发环境中自动加载【英文标题】：Websocket controller not being auto loaded in Rails dev environment 【发布时间】：2018-07-06 18:15:48 【问题描述】：所以自从我开始使用websocket-rails gem 以来，我一直有这个问题。显然它不能自动加载我的“广播控制器”并且阻止我在命令行上运行 rails 命令。
我过去常常通过注释掉事件文件并加载内容来解决这个问题。老实说，它是一个废话，有时它可以工作，有时它不会，但最近我还没有让它工作，我一直在尝试调试它一段时间，但老实说我被卡住了。
这只发生在开发中。
有人有什么想法吗？
这是错误堆栈：

end
end
这就是我的 events.rb 文件的样子：
WebsocketRails::EventMap.describe do
# You can use this file to map incoming events to controller actions.
# One event can be mapped to any number of controller actions. The
# actions will be executed in the order they were subscribed.
# subscribe :client_connected, 'groups#new_user'
#
# Uncomment and edit the next line to handle the client connected event:
# subscribe :client_connected, :to => Controller, :with_method => :method_name
#
# Here is an example of mapping namespaced events:
# namespace :product do
# subscribe :new, :to => ProductController, :with_method => :new_product
# end
# namespace :chatroom do
# subscribe :create_room, "groups#create_room"
# subscribe :update_members, 'groups#update'
# end
# namespace :members do
subscribe :register_member, "broadcasts#register_member_to_group"
subscribe :unregister, "broadcasts#delete_member_from_group"
subscribe :cover_member, "broadcasts#cover_member_for_group"
subscribe :activate_member, "broadcasts#activate_member"
subscribe :deactivate_member, "broadcasts#deactivate_member"
subscribe :send_chat_message, "broadcasts#send_chat_message"
subscribe :someone_typing, "broadcasts#someone_typing"
subscribe :group_updated, "broadcasts#group_updated"
subscribe :check_in_member, "broadcasts#check_in_member"
subscribe :check_out_member, "broadcasts#check_out_member"
# end
# The above will handle an event triggered on the client like `product.new`.
end
