Question

从sinatra route调用构建器模板时出现此错误：

错误的参数数量（1表示0）

Sinatra - 1.1.2

Builder - 3.0.0

MongoMapper - 0.8.6

这样称呼：

get '/current_load.xml' do
  @caption = "Load Average"
  @sub_caption = "5 minutes"

  @time = Performance.where(:NAGIOS_SERVICEDESC => "Current Load").fields(:NAGIOS_LONGDATETIME).all

  content_type :xml
  builder :current_load
end

构建器文件就像这样开始：

xml.instruct!

以下是错误的完整描述：

ArgumentError - wrong number of arguments (1 for 0):
 /usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlbase.rb:135:in `to_xs'

 /opt/nec/www/nec/views/current_load.builder:1:in `evaluate_source'

如果我将Builder更改为2.1.2，则不会收到任何错误要么如果我把MongoMapper拿出来我没有收到任何错误

听起来像两个宝石之间的问题??

Answer 1

Sinatra 1.1.3成功修复了此错误。

这是环境中唯一的变化
