我昨天将Django REST Framework升级到3.5.0因为我需要很好的模式生成。
我正在使用 Django REST Swagger 来记录我的API,但不知道如何列出API端点提供的所有可能的响应消息。
似乎自动生成与我的终端正在执行的操作相对应的成功消息。
所以POST动作生成201响应代码,没有任何描述。
如何添加我的端点提供的所有响应消息并为其提供一些说明?
我正在使用
djangorestframework==3.5.0
django-rest-swagger==2.0.7
答案 0 :(得分:20)
但是!这是黑客攻击 - 可能drf + drf swagger不支持;基本上问题与drf和drf swagger代码没有关系,而是openapi编解码器,看看你自己:
def _get_responses(link):
"""
Returns minimally acceptable responses object based
on action / method type.
"""
template = {'description': ''}
if link.action.lower() == 'post':
return {'201': template}
if link.action.lower() == 'delete':
return {'204': template}
return {'200': template}
上述代码位于:openapi_codec/encode.py
- github
这与drf或drf swagger没有任何关联 - 只为每个链接(例如:GET / api / v1 / test /)创建一个空描述的模板。
当然,有可能克服这个问题。但正如我所说 - 这是黑客攻击:)我将与你分享一个例子:
from rest_framework import exceptions
from rest_framework.permissions import AllowAny
from rest_framework.renderers import CoreJSONRenderer
from rest_framework.response import Response
from rest_framework.views import APIView
from rest_framework_swagger import renderers
from docs_swagger.schema_generator import CustomSchemaGenerator
def get_swagger_view(title=None, url=None):
"""
Returns schema view which renders Swagger/OpenAPI.
(Replace with DRF get_schema_view shortcut in 3.5)
"""
class SwaggerSchemaView(APIView):
_ignore_model_permissions = True
exclude_from_schema = True
permission_classes = [AllowAny]
renderer_classes = [
CoreJSONRenderer,
renderers.OpenAPIRenderer,
renderers.SwaggerUIRenderer
]
def get(self, request):
generator = CustomSchemaGenerator(title=title, url=url) # this is altered line
schema = generator.get_schema(request=request)
if not schema:
raise exceptions.ValidationError(
'The schema generator did not return a schema Document'
)
return Response(schema)
return SwaggerSchemaView.as_view()
我在CustomSchemaGenerator中的操作如下:
import urlparse
import coreapi
from rest_framework.schemas import SchemaGenerator
from openapi_codec import encode
def _custom_get_responses(link):
detail = False
if '{id}' in link.url:
detail = True
return link._responses_docs.get(
'{}_{}'.format(link.action, 'list' if not detail else 'detail'),
link._responses_docs
)
# Very nasty; Monkey patching;
encode._get_responses = _custom_get_responses
class CustomSchemaGenerator(SchemaGenerator):
def get_link(self, path, method, view):
"""
Return a `coreapi.Link` instance for the given endpoint.
"""
fields = self.get_path_fields(path, method, view)
fields += self.get_serializer_fields(path, method, view)
fields += self.get_pagination_fields(path, method, view)
fields += self.get_filter_fields(path, method, view)
if fields and any([field.location in ('form', 'body') for field in fields]):
encoding = self.get_encoding(path, method, view)
else:
encoding = None
description = self.get_description(path, method, view)
if self.url and path.startswith('/'):
path = path[1:]
# CUSTOM
data_link = coreapi.Link(
url=urlparse.urljoin(self.url, path),
action=method.lower(),
encoding=encoding,
fields=fields,
description=description
)
data_link._responses_docs = self.get_response_docs(path, method, view)
return data_link
def get_response_docs(self, path, method, view):
return view.responses_docs if hasattr(view, 'responses_docs') else {'200': {
'description': 'No response docs definition found.'}
}
最后:
class TestViewSet(viewsets.ModelViewSet):
queryset = Test.objects.all()
serializer_class = TestSerializer
responses_docs = {
'get_list': {
'200': {
'description': 'Return the list of the Test objects.',
'schema': {
'type': 'array',
'items': {
'type': 'object',
'properties': {
'id': {
'type': 'integer'
}
}
}
}
},
'404': {
'description': 'Not found',
'schema': {
'type': 'object',
'properties': {
'message': {
'type': 'string'
}
}
},
'example': {
'message': 'Not found.'
}
}
},
'get_detail': {
'200': {
'description': 'Return single Test object.',
'schema': {
'type': 'object',
'properties': {
'id': {
'type': 'integer'
}
}
}
},
'404': {
'description': 'Not found.',
'schema': {
'type': 'object',
'properties': {
'message': {
'type': 'string'
}
}
},
'example': {
'message': 'Not found.'
}
}
}
}
我认为这更像是有趣而不是真正的解决方案。在当前状态下可能无法实现真正的解决方案。也许你应该问drf swagger的创造者 - 他们是否有计划支持回应?
快乐编码:)
