我有疑問，如何在序列化程式中使用 update()？
序列化程式.py
def update(self, instance, validated_data):
instance.name = validated_data.get('name', instance.name)
instance.description = validated_data.get('description', instance.description)
instance.is_free = validated_data.get('is_free', instance.is_free)
instance.keyarea = validated_data.get('keyarea', instance.keyarea)
instance.subject = validated_data.get('subject', instance.subject)
beneficiary_data = validated_data.get('beneficiary', instance.beneficiary)
instance.beneficiary.set(*[beneficiary_data])
section_data = validated_data.get('section', instance.section)
instance.section.set(*[section_data])
instance.image = validated_data.get('image', instance.image)
instance.instructor = validated_data.get('instructor', instance.instructor)
instance.relevance = validated_data.get('relevance', instance.relevance)
instance.difficulty = validated_data.get('difficulty', instance.difficulty)
instance.contributor = validated_data.get('contributor', instance.contributor)
instance.general_status = validated_data.get('general_status', instance.general_status)
instance.review_status = validated_data.get('review_status', instance.review_status)
instance.save()
return instance
我在這里使用了很多行來更新課程模型，還有其他方法可以簡化嗎？

一般沒問題，但你可以這樣做：
for k, v in validated_data.items():
setattr(instance, k, v)
