我正在尝试调整现有的XMLRenderer来创建自定义的XMLRenderer -
class CustomRenderer(renderers.BaseRenderer):
"""
Renderer which serializes to CustomXML.
"""
media_type = 'application/xml'
format = 'xml'
charset = 'utf-8'
def render(self, data, accepted_media_type=None, renderer_context=None):
"""
Renders *obj* into serialized XML.
"""
if data is None:
return ''
stream = StringIO()
xml = SimplerXMLGenerator(stream, self.charset)
xml.startDocument()
xml.startElement("job id='string1'", {})
self._to_xml(xml, data)
xml.endElement("job")
xml.endDocument()
return stream.getvalue()
def _to_xml(self, xml, data):
if isinstance(data, (list, tuple)):
for item in data:
xml.startElement("string2", {})
self._to_xml(xml, item)
xml.endElement("string2")
elif isinstance(data, dict):
for key, value in six.iteritems(data):
xml.startElement(key, {})
self._to_xml(xml, value)
xml.endElement(key)
elif data is None:
# Don't output any value
pass
else:
xml.characters(smart_text(data))
对于string1,我希望它从调用它的视图中获取值。 string1 = API中GET的主键。
即。如果我正在呼叫http://localhost/API/2345 then string1 = 2345
对于string2,我希望它返回类似于他们在以下帖子中所做的模型名称 -
Adding root element to json response (django-rest-framework)
这是自定义呈现器返回的值,以便可以将JSON / XML的根值设置为模型名称。
我已经尝试调整CustomRenderer以包含行但是在运行我的视图时它抱怨我的views.py上的“object()没有参数” -
if request.method == 'GET':
DEV = Trgjob.objects.using('database1').filter(job_id=pk).order_by('job_order')
serializer = CustomSerializer(DEV, many=True)
return CustomRenderer(serializer.data)
答案 0 :(得分:1)
看起来你正试图从视图中返回渲染器实例?
您应该只从视图返回常规数据,但使用视图类上的renderer_classes
属性设置渲染器类。
class MyView(APIView):
renderer_classes = [CustomRenderer]
...
def get(self, request, pk=None):
DEV = Trgjob.objects.using('database1').filter(job_id=pk).order_by('job_order')
serializer = CustomSerializer(DEV, many=True)
return Response(serializer.data)
修改:至于从视图中为渲染器添加额外的上下文...您可以通过检查renderer_context['view']
来做到这一点,所以render()
中的这些内容就是这样的方法...
view = renderer_context['view']
job_id = view.kwargs['job_id']
