ruby-on-rails - 我该如何解决这个烦人的 syntastic rails 错误

Question

我在 rails 中有以下代码

<% @post.errors.full_messages.each do |msg| %>                                                                                                     
             <li><%= msg %></li>                                                                                                                              
<% end %>  

SyntasticCheck VIM 插件一直显示这个错误

app/views/posts/new.html.erb[Syntax: line:12 (1)]
1 app/views/posts/new.html.erb|12 warning| possibly useless use of a variable in void context

Answer 1

如果您只想不再看到这些消息:

let g:syntastic_eruby_ruby_quiet_messages =
    \ {'regex': 'possibly useless use of a variable in void context'}
