rjs中的Ruby'if'条件

Question

我想仅在用户对象（@row）不为nil时才在用户列表中插入用户。如何在rjs模板中有条件地插入？

  

page.insert_html：bottom，：userlist，   render（：partial =＆gt;“user”，：locals =＆gt;   {：user =＆gt; @row，：myid =＆gt; @ row.id}）

非常感谢。

Answer 1

你是如何在普通红宝石中做到的

if @row
  page.insert_html(:bottom, :userlist, render(:partial => "user", :locals =>  { :user => @row, :myid => @row.id }))
end

或者如果你想要它在一行

page.insert_html(:bottom, :userlist, render(:partial => "user", :locals =>  { :user => @row, :myid => @row.id })) if @row

Answer 2

page.insert_html :bottom, :userlist, render(:partial => "user", :locals =>  { :user => @row, :myid => @row.id }) unless @row.blank?
