我在rails上工作,突然rails服务器停止工作.它工作正常,我使用了以下命令[平台窗口7]
gem install -v=2.3.5 rails
当我使用时rails s,它会给出以下错误:
c:/Ruby193/lib/ruby/gems/1.9.1/gems/rails-2.3.5/lib/rails_generator/options.rb:32:in `default_options': undefined method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError)

我在铁轨中使用水豚代替webrat.我已经安装了水豚并在Gemfile中使用了宝石'capybara'.我用的时候
page.should have_selector("title", :text => "anything title")
它给出了一个错误
Failure/Error: page.should have_selector("title", :text => "anything title")
expected css "title" with text "anything title" to return something
测试文件如下:
require 'spec_helper'
describe "Test pages" do
describe "Home page" do
it "should have the content 'Demo App'" do
visit '/test_pages/home'
page.should have_selector("title", :text => "anything title")
end
end
end
在轨道上工作,图像不可见并出错.
Started GET "/assets/home.png" for 127.0.0.1 at 2012-06-19 12:23:24 +0530
Served asset /home.png - 404 Not Found (24ms)
ActionController::RoutingError (No route matches [GET] "/assets/home.png"):
我用过命令
rake assets:precompile
production.rb
config.assets.compress = true
config.assets.compile = false
application.rb中
config.assets.enabled = true
config.assets.version = '1.0'
谢谢你的帮助!
我正在使用PaypalAdaptive.它正确发送ipn_notification.ipnNotification动作方法如下 -
def ipn_notification
ipn = PaypalAdaptive::IpnNotification.new
ipn.send_back(request.raw_post.to_json)
print "=====================request.raw_post#{request.raw_post}=============="
if ipn.verified?
PaymentMailer.notify_unknown(request.raw_post).deliver
else
logger.info "IT DIDNT WORK"
end
render :nothing => true
end
但它返回错误
WARNING: Can't verify CSRF token authenticity rails
对此问题有任何帮助.
我正在研究Ruby on Rails.一个在本地服务器上正常工作的项目,当我在heroku上部署它时会出现以下错误.谢谢!
