我有一个rails应用程序,它通过以下方式调用视图中的辅助方法:
<%= link_to_receipts @purchase_request %>
在我的帮手中:
link_to_receipts purchaserequest
purchaserequest.receipts.each_with_index do |receipt,i|
#some code here commented out...
end
end
但它在视图上输出数组:
[#&gt; tagged_by:“joe somebody”,purchase_request_id:39,created_at:“2011-08-22 20:39:18”,updated_at:“2011-08-22 20:39:18”&gt;]
如果我注释掉each_with_index,它将不会显示数组,但如果存在则会显示数组。有什么想法吗?

我发现了问题。在帮助器方法中,我首先在块中初始化变量html,如下所示:
link_to_receipts purchaserequest
purchaserequest.receipts.each_with_index do |receipt,i|
html = ""
#more code here
end
end
当它应该在块之外声明时:
link_to_receipts purchaserequest
html = ""
purchaserequest.receipts.each_with_index do |receipt,i|
#code here
end
end
