egon新书python全套来袭:https://egonlin.com/book.html
响应模块
1、作用
根据 用户请求URL 或 用户可接受的类型,筛选出合适的 渲染组件。
用户请求URL:
http://127.0.0.1:8000/test/?format=json
http://127.0.0.1:8000/test.json
2、内置渲染器
显示json格式:JSONRenderer
访问URL:
默认显示格式:BrowsableAPIRenderer(可以修改它的html文件)
访问URL:
表格方式:AdminRenderer
访问URL:
- http://127.0.0.1:8000/test/?format=admin
- http://127.0.0.1:8000/test.admin
- http://127.0.0.1:8000/test/
form表单方式:HTMLFormRenderer
访问URL:
3、局部使用
from rest_framework.renderers import HTMLFormRenderer,BrowsableAPIRenderer
class BookDetailView(APIView):
renderer_classes = [HTMLFormRenderer,BrowsableAPIRenderer ]
def get(self,request,pk):
book_obj=models.Book.objects.filter(pk=pk).first()
bs=BookSerializers(book_obj,many=False)
return Response(bs.data)
def put(self,request,pk):
book_obj = models.Book.objects.filter(pk=pk).first()
bs=BookSerializers(data=request.data,instance=book_obj)
if bs.is_valid():
bs.save() # update
return Response(bs.data)
else:
return Response(bs.errors)
def delete(self,request,pk):
models.Book.objects.filter(pk=pk).delete()
return Response("")
4、全局使用
4-1 settings.py中配置
REST_FRAMEWORK = {
'DEFAULT_RENDERER_CLASSES': ['rest_framework.renderers.JSONRenderer']
}
5、自定义显示模块
from rest_framework.renderers import TemplateHTMLRenderer
class BookDetailView(APIView):
renderer_classes = [TemplateHTMLRenderer]
def get(self,request,pk):
book_obj=models.Book.objects.filter(pk=pk).first()
bs=BookSerializers(book_obj,many=False)
return Response(bs.data,template_name='aa.html')
