警告：不能使用捲曲

Question

我使用的鐵軌2.3.5，1.9.3紅寶石路過XML時，大量分配這些屬性的保護，RubyGems的1.8.24和Mac OS X獅子

我傳遞這個文件中，「invoice.xml.erb」使用捲曲：

<invoice> 
.... 
<invoice_detail> 
.... 
</invoice_detail> 
</invoice> 

我期待有發票領域的填補，也invoice_details的領域，但是當我通過捲曲的命令，只是發票領域正在填充，並且發生此錯誤：警告：無法批量分配這些受保護的屬性：inventoryDocId，invoice_detail

這裏是我的模型：

invoice.rb

class Invoice < ActiveRecord::Base 
set_table_name "inventoryDocHeader" 
set_primary_key "inventoryDocId" 
has_many :invoice_detail, :foreign_key => "inventoryDocId" 
attr_accessible :inventoryDocId, :originDocId, :siteCode, :transCode, :typeCode, :docCode, :partyTerms,:locationCode, :otherCharges, :grossPrice, :netPrice, :amountPaid, :amountPending, :amountReturned, :RSiteCode, :RInventoryDocId, :RDocCode, :ROriginDocId, :batchCode, :partyCharges, :partyShipmentTermsText, :estimateVolume, :originCountryId, :consigneeName, :consigneeAddress1, :consigneeAddress2, :consigneeAddress3, :notifyPartyName, :notifyPartyAddress1, :notifyPartyAddress2, :notifyPartyAddress3 

end 

invoice_detail.rb

class InvoiceDetail < ActiveRecord::Base 
set_table_name "inventoryDocDetail" 
belongs_to :invoice, :foreign_key => "inventoryDocId" 
attr_accessible :inventoryDocId, :lineNumber, :parentLineNumber, :productCode, :actualQuantity, :unitCode, :contentQuantity, :cost, :price, :commission, :factorRate, :referenceLineNumber 
end 

任何建議都歡迎。謝謝！

您必須將:invoice_detail_attributes添加到第一個錯誤的attr_accessible命令中。第二個是你從Invoice或InvoiceDetails模型中獲取它嗎？
