django serializers小结
1、模型。
from django.contrib.auth.hashers import check_password
from django.db import models
# Create your models here.
class User(models.Model):
name = models.CharField(max_length=128, verbose_name='姓名')
mobile = models.CharField(max_length=11, unique=True, verbose_name="手機號")
pwd = models.CharField(max_length=128, verbose_name='密码')
class Meta:
db_table = 'users'
verbose_name = "用戶信息"
def __str__(self):
return self.name
def verify_password(self, pwd):
return check_password(pwd, self.employee_pwd)
2、路由。
url(r'^Reginster/$', views.ReginsterView.as_view({'post': 'create'})),
3、序列化。
import re
from django.contrib.auth.hashers import make_password
from rest_framework import serializers
from api import models
class RegisterSerializer(serializers.ModelSerializer):
pwd2=serializers.CharField(max_length=11,write_only=True)
class Meta:
model = models.User
fields = '__all__' # 输出所有字段
# exclude = ['pwd'] # 过滤密码字段
def validate_mobile(self, value):
if not re.match(r"^1[3-9]\d{9}", value):
raise serializers.ValidationError("手機號碼格式不正確！")
return value
def validate(self, attrs):
if attrs['pwd'] != attrs['pwd2']:
raise serializers.ValidationError("兩次密碼輸入不一致！")
if not attrs['pwd'].startswith('pbkdf2_'):
attrs['pwd'] = make_password(attrs['pwd'])
del attrs["pwd2"] # 移除不在model但是需要校验的字段
return attrs
4、视图。
from django.shortcuts import render,HttpResponse
from django.views.decorators.csrf import csrf_exempt
from rest_framework.response import Response
from rest_framework.viewsets import ModelViewSet
# Create your views here.
from api.ser import RegisterSerializer
class ReginsterView(ModelViewSet):
serializer_class=RegisterSerializer
def post(self, request, *args, **kwargs):
ser=self.serializer_class(data=request.data)
ser.is_valid(raise_exception=True)
try:
self.perform_create(ser)
return Response({'code': 200, 'msg': '新增成功！'})
except:
return Response({'code': 400, 'msg': '新增失败！'})5、结果。
6、extra，添加额外的输出。
class RegisterSerializer(serializers.ModelSerializer):
days_since_joined=serializers.SerializerMethodField()
# 方法写法：get_ + 字段
def get_days_since_joined(self, obj):
# obj指这个model的对象
return '%s-24'%obj.name
