原始碼示例：

from rest_framework import serializers
from set.models import Set


class SetSerializers(serializers.ModelSerializer):
    """
    配置資訊序列化
    """
    product_id = serializers.IntegerField()
    create_time = serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S", required=False, read_only=True)
    update_time 
 
= serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S", required=False, read_only=True)

    class Meta:
        module = Set
        fields = ('id', 'setname', 'setvalue', 'product_id', 'create_time', 'update_time')

執行錯誤：

  File "D:\Program Files\Python38\lib\site-packages\django\utils\functional.py
 
", line 80, in __get__
    res = instance.__dict__[self.name] = self.func(instance)
  File "D:\Program Files\Python38\lib\site-packages\rest_framework\serializers.py", line 370, in _writable_fields
    field for field in self.fields.values()
  File "D:\Program Files\Python38\lib\site-packages\rest_framework\serializers.py
 
", line 363, in fields
    for key, value in self.get_fields().items():
  File "D:\Program Files\Python38\lib\site-packages\rest_framework\serializers.py", line 977, in get_fields
    assert hasattr(self.Meta, 'model'), (
AssertionError: Class SetSerializers missing "Meta.model" attribute

解決方法：

以上問題是由於在序列化器中缺失或者寫錯以下欄位

class Meta:       
    model = Set
