我得到“堆栈级别太深”在 Rails 3 和 mongoid 环境中保存/创建实例时出错？
在 Rails 3 和 mongoid 环境中保存/创建实例时出现“堆栈级别太深”错误？
没有错误：
@nameq = Question.new(:survey_id => @survey.id, :title => 'Example Question', :required_question => true, :input => 'string', :uuid => Time.now.to_i, :position => 1)
错误“堆栈级别太深”
@nameq = Question.create(:survey_id => @survey.id, :title => 'Example Question', :required_question => true, :input => 'string', :uuid => Time.now.to_i, :position => 1)
这种情况的常见原因是什么？

1）捕获该错误：
开始
富
救援系统堆栈错误
把$！
放置调用者[0..100]
结束
2) :自动保存 =>两个模型中的 true 可能是负责的
1) catch that error:
begin
foo
rescue SystemStackError
puts $!
puts caller[0..100]
end
2) :autosave => true in two models could be responsible
