相关application_controller代码:
class ApplicationController < ActionController::Base
include Facebooker2::Rails::Controller
helper :all # include all helpers, all the time
protect_from_forgery
layout :layout_by_resource
before_filter :set_cache_buster
before_filter :current_facebook_user, :only => :after_sign_in_path_for
helper_method :current_facebook_client, :only => :after_sign_in_path_for
...
end
它是在"helper_method:current_facebook_client，:only =>:after_sign_in_path_for"，但对于我的生活，我看不出语法有什么问题(特别是因为它在1.8.7中工作。
对helper_method的方法调用是错误的，helper_method(*meths)接受一个可变数量的代表助手名称的符号，它不接受一个opts散列helper_method(*meths, opts = {})
# from http://api.rubyonrails.org/
helper_method(*meths)
# Declare a controller method as a helper. For example, the
# following makes the current_user controller method available to the view:
class ApplicationController < ActionController::Base
helper_method :current_user, :logged_in?
def current_user
@current_user ||= User.find_by_id(session[:user])
end
def logged_in?
current_user != nil
end
end
