Sinatra、MongoMapper 和 Builder 的参数数量错误（1 代表 0）
从 sinatra 路线调用构建器模板时出现此错误：
参数数量错误（1 代表 0）
Sinatra - 1.1.2
Builder - 3.0.0
MongoMapper - 0.8.6
这样调用：
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
构建器文件如下所示：
xml.instruct!
这是 的完整跟踪错误：
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'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlbase.rb:135:in `_escape'

/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:284:in `_special'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:250:in `instruct!'
/opt/nec/www/nec/views/current_load.builder:1:in `evaluate_source'
如果我将 Builder 更改为 2.1.2，则不会收到错误 或者 如果我取出 MongoMapper，我不会收到任何错误
听起来像是两个 gem 之间的问题？
I am getting this error when calling a builder template from sinatra route:
wrong number of arguments (1 for 0)
Sinatra - 1.1.2
Builder - 3.0.0
MongoMapper - 0.8.6
Calling it like this:
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
the builder file starts off like this:
xml.instruct!
Here's the full trace of the error:
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'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlbase.rb:135:in `_escape'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlbase.rb:140:in `_escape_quote'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:320:in `_attr_value'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:308:in `_insert_attributes'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:306:in `each'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:306:in `_insert_attributes'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:284:in `_special'
/usr/lib/ruby/gems/1.8/gems/builder-3.0.0/lib/builder/xmlmarkup.rb:250:in `instruct!'
/opt/nec/www/nec/views/current_load.builder:1:in `evaluate_source'
If I change Builder to 2.1.2, I receive no error
or
If I take MongoMapper out I receive no error
Sounds like an issue between two gems??

Sinatra 1.1.3 成功修复了这个错误。
这是环境唯一的改变
