Rails提供filter_parameter_logging来过滤rails日志中的敏感参数.

如果您有一个JSONP API,URL中可能会出现一些敏感信息.有没有办法从日志中过滤请求URL？

短而甜蜜,

是否可以使用(当前版本)Ruby 1.9.1与Rails 2.3.5？

感谢您提供更多信息!

我正在使用rails 2.3.5,我希望我们Rspec进行测试.我已经安装了rspec gem但是无法在生成器列表中列出rspec.我指的是https://github.com/rspec/rspec-rails.

group :development, :test do
  gem "rspec", "~> 1.3"
  gem "rspec-rails", "~> 1.3"
end

谢谢.

我试图运行bundle exec rake db:migrate然后遇到以下错误.

bundle exec rake db:migrate --trace

我使用rails 2.3.11,ruby-1.9.2-p320.尝试运行脚本/服务器,但收到此错误: -

然后我在SO上提到几个答案并从终端运行以下命令: -

system@admin:~/apps/app_name/trunk$ gem update --system 1.8.25

现在我收到错误: -

我正在学习rubyonrails并参考http://guides.rubyonrails.org/获取文档,并参考http://railscasts.com/进行截屏.是否有更多这样有用的网站可以帮助我更多地了解rubyonrails？

我在我的模型中有验证方法

def validate
  super    
  if some condition
    errors.add('', 'some text')
  end
end

此方法调用Create和Update.我不想打电话给Update.我怎样才能做到这一点？

我正在使用rails2.3.11和jruby.

更新:我可以使用这个validate :custom_validation, :on => :create,但他们如何调用创建和更新？

我也检查了一下validate_on_create,但是当我打电话的时候我仍然没有想到validate？

我试图在10秒内到期密钥,不知怎的,但是没有使用rspec.在这个过程中,我注意到Rails.cache.write回报falseRails中2.3.11,而Rails.cache.write回报true在Rails的3.2.11,这是一个问题？为什么价值不同？为什么Rails 2.3.11返回false并Rails 3.2.11返回true？

Rails 2.3.11

irb(main):001:0> Rails.cache.write("test", "java", :expires_in => 10.seconds)
=> false

Rails 3.2.11

irb(main):001:0> Rails.cache.write("test", "java", :expires_in => 10.seconds)
=> true

我使用带有Rails 2.3.11的jruby 1.6.5.1和带有Rails 3.2.11的jruby 1.7.3.

如何获得金钱的绝对价值？例如:

-2.to_money.? = 2.to_money
 2.to_money.? = 2.to_money

我有一个属性total_price,可能是正面或负面的.我想计算total_price的绝对值.

在我的Rails应用程序(Rails 2.3.14和Ruby 1.8.7)中,我试图将日期时间字符串转换为不同的格式,以便在我的MySQL数据库上执行搜索但是我收到 invalid date错误,我似乎无法弄清楚为什么,我已经阅读了一些类似的问题,但我似乎仍无法解决这个问题.

# check if filter contains a time stamp
if params[:sSearch].include?('/') and params[:sSearch].include?(':')
  datetime = DateTime.strptime(params[:sSearch], "%Y-%m-%d %H:%M")
  params[:sSearch] = datetime
end

示例场景

04/11/13 16:14

应转换为

2013-11-04 16:14

我认为这可能是因为秒不包含在字符串的前端表示中,因为datetime数据库表中的精确是2013-11-04 16:14:52这样的,所以我现在包括秒,但仍然得到相同的错误,我不知道我认为这应该很重要,因为我LIKE在搜索词的任一侧使用带有通配符的操作数,所以即使没有它应该工作的秒数.
