一、自定义action
- 使用action装饰器
- methods，支持的请求方式，为一个列表，默认为[‘get’]
- detail，必传参数，要处理的是否是详情资源对象（即是否通过url路径获取主键），True表示需要传递主键id，使用通过URL获取的主键对应的数据对象，False表示不需要传递主键id，不使用URL获取主键
- url_path，指定url路由名称，默认为action名称
- url_name，指定url的名称，默认为action名称
action源码：
def action(methods=None, detail=None, url_path=None, url_name=None, **kwargs):
"""
Mark a ViewSet method as a routable action.
`@action`-decorated functions will be endowed with a `mapping` property,
a `MethodMapper` that can be used to add additional method-based behaviors
on the routed action.
:param methods: A list of HTTP method names this action responds to.
Defaults to GET only.
:param detail: Required. Determines whether this action applies to
instance/detail requests or collection/list requests.
:param url_path: Define the URL segment for this action. Defaults to the
name of the method decorated.
:param url_name: Define the internal (`reverse`) URL name for this action.
Defaults to the name of the method decorated with underscores
replaced with dashes.
:param kwargs: Additional properties to set on the view. This can be used
to override viewset-level *_classes settings, equivalent to
how the `@renderer_classes` etc. decorators work for function-
based API views.
"""
methods = ['get'] if (methods is None) else methods
methods = [method.lower() for method in methods]
assert detail is not None, (
"@action() missing required argument: 'detail'"
)
# name and suffix are mutually exclusive
if 'name' in kwargs and 'suffix' in kwargs:
raise TypeError("`name` and `suffix` are mutually exclusive arguments.")
def decorator(func):
func.mapping = MethodMapper(func, methods)
func.detail = detail
