我正在使用 Builder 在 Ruby 中创建 xml。当我调用 generate_object 方法两次时，它工作正常。但是，在循环中执行此操作时，我会得到一些奇怪的结果。两次输入都是一样的。

这是代码。

def generate_xml
    xml = Builder::XmlMarkup.new

  #this doesn't work
  #objects.each do |o|
  #  generate_object xml, o
  #end
  #this works...
  generate_object(xml, objects[0])
  generate_object(xml, objects[1])          
end
def generate_object(builder, object)
    builder.__send__('ins0', :zObjects, 'xsi:type' => "ins1:account") do |a|
        object.to_hash.each do |k,v|
            #puts "key #{k} #{v}!!!!!!!!!!!!!!!!!!!"
            a.__send__('ins1', k.to_s.zuora_camelize.to_sym, v) unless v.nil?
        end
    end
end

循环通过对象打印：

<env:Body>
  <ins0:create>
    [#<Zuora::Objects::Account:0x007fcd69d61788 
      @changed_attributes={
        "auto_pay"=>nil, 
        "currency"=>nil, 
        "batch"=>nil, 
        "bill_cycle_day"=>nil, 
        "status"=>nil, 
        "payment_term"=>nil, 
        "name"=>nil
      },
      @auto_pay=false, 
      @currency="USD", 
      @batch="Batch1", 
      @bill_cycle_day=1, 
      @status="Draft", 
      @payment_term="Due Upon Receipt", 
      @name="test">, 
    #<Zuora::Objects::Account:0x007fcd69d60d10 
      @changed_attributes={
        "auto_pay"=>nil, 
        "currency"=>nil, 
        "batch"=>nil, 
        "bill_cycle_day"=>nil, 
        "status"=>nil, 
        "payment_term"=>nil, 
        "name"=>nil
      }, 
      @auto_pay=false, 
      @currency="USD", 
      @batch="Batch1", 
      @bill_cycle_day=1, 
      @status="Draft", 
      @payment_term="Due Upon Receipt", 
      @name="test 2">
    ]
  </ins0:create>
</env:Body>

在没有循环的情况下执行这两个调用：

<env:Body>
  <ins0:create>
    <ins0:zObjects xsi:type="ins1:account">
      <ins1:AutoPay>false</ins1:AutoPay>
      <ins1:Batch>Batch1</ins1:Batch>
      <ins1:BillCycleDay>1</ins1:BillCycleDay>
      <ins1:Currency>USD</ins1:Currency>
      <ins1:Name>test</ins1:Name>
      <ins1:PaymentTerm>Due Upon Receipt</ins1:PaymentTerm>
      <ins1:Status>Draft</ins1:Status>
    </ins0:zObjects>
    <ins0:zObjects xsi:type="ins1:account">
      <ins1:AutoPay>false</ins1:AutoPay>
      <ins1:Batch>Batch1</ins1:Batch>
      <ins1:BillCycleDay>1</ins1:BillCycleDay>
      <ins1:Currency>USD</ins1:Currency>
      <ins1:Name>test 2</ins1:Name>
      <ins1:PaymentTerm>Due Upon Receipt</ins1:PaymentTerm>
      <ins1:Status>Draft</ins1:Status>
    </ins0:zObjects>
  </ins0:create>
</env:Body>

看起来您只是将 .each 的输出与您想要返回的内容混为一谈。

尝试：

def generate_xml
  xml = Builder::XmlMarkup.new

  objects.each do |o|
    generate_object xml, o
  end
  # Return the builder object, not the output of .each (the list of objects)!
  xml
end
