VuedaReadOnlyViewSet

Overview

Read-only ViewSet for VUEDA models. Provides list and retrieve only, with the same flex-fields, query-parameter validation, and row-level filtering as VuedaViewSet.

get_allowed_extra_actions

Override this function to change if a user is allowed to do a certain action.

request is None when model metadata or available_actions is built from a serializer context without a request. An override must handle that case before reading request.user.

Unlike :meth:VuedaViewSet.get_allowed_extra_actions, this offers every extra action unconditionally, including no read gate for history_list: that action is defined only on VuedaViewSet, so it never appears in get_extra_actions() here, and there is nothing for a read gate to filter.

Signature

get_allowed_extra_actions(self, request, instance)

Parameters

Name	Type	Required	Default	Description
self		yes
request		yes
instance		no	None
