Question

我遇到jruby和activerecord-3.1.0.rc5的多个问题。

例如，在我运行迁移之后，我从rails控制台创建了一个简单的Role对象，一切都很好：

jruby-1.6.3 :006 > r = Role.new(:name => "Standard")
 => #<Role id: nil, name: "Standard", created_at: nil, updated_at: nil>

然后我要显示所有角色，以便我输入

jruby-1.6.3：007＆gt; Role.all

我得到以下堆栈跟踪：

argumentError: wrong number of arguments (3 for 2)
    from /Users/paulcowan/.rvm/gems/jruby-1.6.3/gems/activerecord-3.1.0.rc5/lib/active_record/base.rb:470:in `find_by_sql'

    from org/jruby/RubyKernel.java:1047:in `require'
    from script/rails:6:in `(root)'

我收到以下错误：

ArgumentError：错误的参数数量（3为2）

Rails 3.1r5相当多。整件事看起来很蠢。还有其他人遇到过这些问题吗？

我提到了一些非常相似的here：

ActiverREcord似乎失败了。

以下是我用于jruby数据访问的内容：

gem 'activerecord-jdbc-adapter'
gem 'activerecord-jdbcsqlite3-adapter'
gem 'jdbc-sqlite3', :require => false

还有其他人遇到这些问题吗？

来自JRuby的activerecord-3.1.0.rc5。似乎没什么用
