SchemaGenerator
.- Parameters:

version (str) – API version string; if omitted, info.default_version will be used
url (str) –
API scheme, host and port; if
None
is passed andDEFAULT_API_URL
is not set, the url will be inferred from the request made against the schema view, so you should generally not need to set this parameter explicitly; if the empty string is passed, no host and scheme will be emittedIf url is not
None
or the empty string, it must be a scheme-absolute uri (i.e. starting with http:// or https://), and any path component is ignored;See also: documentation on base URL construction
patterns – if given, only these patterns will be enumerated for inclusion in the API spec
urlconf – if patterns is not given, use this urlconf to enumerate patterns; if not given, the default urlconf is used

return result
(the default implementation).- Parameters:
result – the return value of the winning inspector, or
None
if no inspector handled the objectmethod_name (str) – name of the method that was called on the inspector

- class drf_yasg.openapi.SwaggerDict(**attrs)[source]¶

OrderedDict
A particular type of OrderedDict, which maps all attribute accesses to dict lookups using
make_swagger_name()
. Attribute names starting with_
are set on the object as-is and are not included in the specification output.Used as a base class for all Swagger helper models.
- _insert_extras__()[source]¶
From an ordering perspective, it is desired that extra attributes such as vendor extensions stay at the bottom of the object. However, python2.7’s OrderedDict craps out if you try to insert into it before calling init. This means that subclasses must call super().__init__ as the first statement of their own __init__, which would result in the extra attributes being added first. For this reason, we defer the insertion of the attributes and require that subclasses call ._insert_extras__ at the end of their __init__ method.

Decorate a view method to customize the
Operation
object generated from it.method and methods are mutually exclusive and must only be present when decorating a view method that accepts more than one HTTP request method.
The auto_schema and operation_description arguments take precedence over view- or method-level values.
- Parameters:
method (str) – for multi-method views, the http method the options should apply to
methods (list[str]) – for multi-method views, the http methods the options should apply to
auto_schema (drf_yasg.inspectors.SwaggerAutoSchema) – custom class to use for generating the Operation object; this overrides both the class-level
swagger_schema
attribute and theDEFAULT_AUTO_SCHEMA_CLASS
setting, and can be set toNone
to prevent this operation from being generatedrequest_body (drf_yasg.openapi.Schema or drf_yasg.openapi.SchemaRef or rest_framework.serializers.Serializer or type[no_body]) –
custom request body which will be used as the
schema
property of aParameter
within: 'body'
.A Schema or SchemaRef is not valid if this request consumes form-data, because
form
andbody
parameters are mutually exclusive in anOperation
. If you need to set customform
parameters, you can use the manual_parameters argument.If a
Serializer
class or instance is given, it will be automatically converted into aSchema
used as abody
Parameter
, or into a list ofform
Parameter
s, as appropriate.query_serializer (rest_framework.serializers.Serializer) –
if you use a
Serializer
to parse query parameters, you can pass it here and haveParameter
objects be generated automatically from it.If any
Field
on the serializer cannot be represented as aquery
Parameter
(e.g. nested Serializers, file fields, …), the schema generation will fail with an error.Schema generation will also fail if the name of any Field on the query_serializer conflicts with parameters generated by
filter_backends
orpaginator
.manual_parameters (list[drf_yasg.openapi.Parameter]) –
a list of manual parameters to override the automatically generated ones
Parameter
s are identified by their (name
,in
) combination, and any parameters given here will fully override automatically generated parameters if they collide.It is an error to supply
form
parameters when the request does not consume form-data.operation_id (str) – operation ID override; the operation ID must be unique across the whole API
operation_description (str) – operation description override
operation_summary (str) – operation summary string
security (list[dict]) – security requirements override; used to specify which authentication mechanism is required to call this API; an empty list marks the endpoint as unauthenticated (i.e. removes all accepted authentication schemes), and
None
will inherit the top-level security requirementsdeprecated (bool) – deprecation status for operation
responses (dict[int or str, (drf_yasg.openapi.Schema or drf_yasg.openapi.SchemaRef or drf_yasg.openapi.Response or str or rest_framework.serializers.Serializer)]) –
a dict of documented manual responses keyed on response status code. If no success (
2xx
) response is given, one will automatically be generated from the request body and http method. If any2xx
response is given the automatic response is suppressed.if a plain string is given as value, a
Response
with no body and that string as its description will be generatedif
None
is given as a value, the response is ignored; this is mainly useful for disabling default 2xx responses, i.e.responses={200: None, 302: 'something'}
if a
Schema
,SchemaRef
is given, aResponse
with the schema as its body and an empty description will be generateda
Serializer
class or instance will be converted into aSchema
and treated as abovea
Response
object will be used as-is; however if itsschema
attribute is aSerializer
, it will automatically be converted into aSchema
