django之序列化数据

Posted 2020-12-23 i-love-xiang

序列化数据
安装命令：pip install djangorestframework
在setting设置文件中的INSTALLED_APPS选项中添加‘rest_framework’

INSTALLED_APPS = [
    ...
    ‘rest_framework‘,
]

1、在model同级目录下新建py文件
2、新建类->继承serializers.ModelSerializer
例如：#序列化类继承

from rest_framework import serializers
from app(你的APP名称).models import *(表名)
class Aserializer(serializers.ModelSerializer):
　　time = serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S")#净化时间输出格式

class Meta: #表名 model = 表名 fields = "__all__"

3、view视图里调用

from app.serializers import *
transactions = 表名.objects.filter.all()
transactions_ser = Aserializer(transactions, many=True)
# print(transactions)
# print(transactions_ser.data)
data = {
    ‘data‘: transactions_ser.data
}
