响应模块
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:
-
http://127.0.0.1:8000/test/?format=json
-http://127.0.0.1:8000/test.json
-http://127.0.0.1:8000/test/
默认显示格式:BrowsableAPIRenderer
(可以修改它的html
文件)
访问URL:
-
http://127.0.0.1:8000/test/?format=api
-http://127.0.0.1:8000/test.api
-http://127.0.0.1:8000/test/
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:
-
http://127.0.0.1:8000/test/?format=form
-http://127.0.0.1:8000/test.form
-http://127.0.0.1:8000/test/
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
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')
