语法错误，意外的keyword_in，需要'|'

Question

该代码有什么问题？

%body
  - In.all.each do |in|
    = link_to in.name, categories_path(in: in.name)
  = yield

我的语法错误：

/home/ubuntu/workspace/app/views/layouts/application.html.haml:10: syntax error, unexpected keyword_in, expecting '|' In.all.each do |in| ^ 
/home/ubuntu/workspace/app/views/layouts/application.html.haml:11: syntax error, unexpected keyword_in, expecting ')' ...e_false_true_false(( link_to in.name, categories_path (in: i... ... ^

in 是保留关键字。尝试使用其他东西作为块变量。
