帮助,我不明白这个rails错误。
我根据bundler的bundle install命令使用最新的rails。
我正在使用Windows 7.
当我运行命令C:/Users/Owner/ruby_intro/graded-assignments/recipefinder/config/initializers/ne
w_framework_defaults.rb:21:in `<top (required)>': undefined method `halt_callbac

时,它会显示如下错误消息:
var result = (from t in TrnExpense
group t by new { t.CreatedOn.Date, t.Note } into g
orderby g.Key.Date descending
select new{
CreatedOn = g.Key.Date,
Note = g.Key.Note,
Count = g.Count()
}).ToList();
有人可以帮忙吗?
谢谢你,请原谅我英语不好。
