這篇文章給大家分享的是有關django基于restframework的CBV封裝怎么實現的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
from django.db import models # Create your models here. class Book(models.Model): title=models.CharField(max_length=32) price=models.IntegerField() pub_date=models.DateField() publish=models.ForeignKey(to="Publish") authors=models.ManyToManyField(to="Author") def __str__(self): return self.title class Publish(models.Model): name=models.CharField(max_length=32) email=models.EmailField() def __str__(self): return self.name class Author(models.Model): name=models.CharField(max_length=32) age=models.IntegerField() def __str__(self): return self.name
from rest_framework import serializers from app01 import models from rest_framework import exceptions class BookSerialize(serializers.ModelSerializer): class Meta: model = models.Book fields = "__all__" publish = serializers.SerializerMethodField() authors = serializers.SerializerMethodField() def get_publish(self, obj): return {"publish_id": obj.publish.pk, "publish_name": obj.publish.name} def get_authors(self, obj): author_list = obj.authors.all() lis = [{"name": author.name, "age": author.age} for author in author_list] return lis def validate_title(self, value): if value.startswith("sb"): raise exceptions.ValidationError('你使用了不合適的文字') return value
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^books/$', views.Books.as_view()), ]
主要就是將CBV的幾個get,post請求方法進行封裝,以后創建其他的新的CBV,直接繼承調用就可以了,可以減少代碼冗余
from app01 import models from rest_framework.response import Response from rest_framework.views import APIView from app01.serialize_module import BookSerialize # 自定義一個response類,方便CBV使用 class MyResponse(): def __init__(self): self.status = 100 self.msg = None # 將類方法裝飾成屬性 @property def get_dic(self): return self.__dict__ # 封裝CBV類 # 將get請求封裝在List類中 class List(): def get_list(self, request,*args,**kwargs): response = MyResponse() try: handler_list = self.model.objects.all() handler_ser = self.serializer(instance=handler_list, many=True) response.handler = handler_ser.data response.msg = "獲取成功" except Exception as e: response.msg="獲取失敗" response.error=str(e) return Response(response.get_dic) # 將post請求封裝在Create類中 class Create(): def save(self, request,*args,**kwargs): response = MyResponse() try: handler_ser = self.serializer(data=request.data) if handler_ser.is_valid(): handler_ser.save() response.msg = "添加成功" else: response.status = 101 response.msg = "添加失敗" response.error = handler_ser.errors except Exception as e: response.msg = "添加失敗" response.error=str(e) return Response(response.get_dic) # book類繼承List,Create,APIView class Books(List,Create,APIView): model=models.Book serializer=BookSerialize # 此時調用get方法時,只要使用List類中的get_list方法就行了 def get(self,request): return self.get_list(request) # 此時調用post方法時,只要使用Create類中的save方法就行了 def post(self,request): return self.save(request)
