提问by ssri
I am learning Haml.
我正在学习哈姆勒。
My view files are like:
我的视图文件是这样的：
show.html.haml:
show.html.haml：
.content
= render 'meeting_info', :locals => { :info => @info }
and _meeting_info.html.haml:
和 _meeting_info.html.haml：
.detail
%table
%caption
Meeting Informations of
= info["meeting_name"]
...
When I tried running this I got an undefined local variable or method 'info'error.
当我尝试运行它时，undefined local variable or method 'info'出现错误。

Try this
Without :localsand :partial
试试这个
没有:locals和:partial
.content
= render 'meeting_info', :info => @info
No need to specify locals.
无需指定本地人。
With :localsand :partial
You should specify locals in following case i.e specifying :partialfor render
使用:locals和:partial
你应该在以下情况下指定本地人，即指定:partial渲染
.content
= render :partial => 'meeting_info', :locals => { :info => @info }

You would use the :localsoption if you're calling render from a controller. When calling render from a view, you would simply do this:
:locals如果您从控制器调用渲染，您将使用该选项。从视图调用渲染时，您只需执行以下操作：
= render 'meeting_info', :info => @info
