DetailViewActionMixin

DetailViewActionMixin

djadmin.actions.view_mixins.DetailViewActionMixin

Mixin for actions that use DetailView (read-only display).

Use for actions that display model instances in read-only mode using the Layout API for structured display.

The action can define a view_layout attribute on the ModelAdmin, or it will fall back to update_layout, layout, or auto-generate layout from model fields.

Examples

class ViewRecordAction(RecordActionMixin, DetailViewActionMixin, BaseAction): pass

In ModelAdmin:

class ProductAdmin(ModelAdmin): view_layout = Layout( Fieldset('Details', Field('name'), Field('price'), ), )
