```slim
= render partial: "issues", object: @order.issues.recent
```

了解一下
http://guides.rubyonrails.org/layouts_and_rendering.html
搜尋 "object:"
http://d.pr/i/XIVq

partial 名稱剛好叫做 issues

```slim
= render :partial => "issues", :locals => { :issues => @order.issues.recent }
```

相當於

```slim
= render :partial => "issues", :object => @order.issues.recent
```
