DRf，分页外键字段

Question

我想做下面的事情，但是代码效率低下，

如何返回相关对象的分页响应？

System.out.println("Title: ");  
               String i = in.nextLine();
                title.add(i);
            try{ 




            FileWriter fw = new FileWriter("C:\\title.txt");
            for(String de: title){
                fw.write(de + System.lineSeparator()); 

            }
            fw.close();

        }catch(Exception e){ System.out.println(e);}
            System.out.println("Sucess..");
        }

找到了答案

想法是平整嵌套对象

class FooSerializer():
    bar = BarSerializer()

    def to_representation(self, obj):
        """Move fields from profile to user representation."""
        representation = super().to_representation(obj)
        profile_representation = representation.pop('bar')
        for key in profile_representation:
            representation[key] = profile_representation[key]

        return representation
