Add Log entry on Model Export Actions

Question

I have enabled Log entries in the Django Admin

class CustomLogEntryAdmin(admin.ModelAdmin):
    list_display = [
        "action_time",
        "user",
        "content_type",
        "object_id",
        "object_repr",
        "action_flag",
        "change_message",
    ]
    # list filter
    list_filter = ["action_time", "user", "content_type"]

    # search
    search_fields = ["user__username", "object_repr"]


admin.site.register(LogEntry, CustomLogEntryAdmin)

And I have another model whose admin.py code is like this

class RegAdmin(ExportActionMixin, admin.ModelAdmin):
    resource_class = RegAdminResource

    def has_view_permission(self, request, obj=None):
        return True

    def has_module_permission(self, request):
        return True

By default all change, addition and deletion entries are logged but I also want to log an entry when any export action is performed on it. ChatGPT suggests that I should something like this

    # in admin class 
    def export_action(self, request, *args, **kwargs):
        # Log the export action
        LogEntry.objects.create(
            user_id=request.user.id,
            content_type_id=ContentType.objects.get_for_model(self.model).id,
            object_id=None,
            object_repr=str(self.model),
            action_flag=1,  # Assuming 1 stands for the action flag of 'change'
            change_message="Export action triggered.",
        )
        return super().export_action(request, *args, **kwargs)

But this function is not triggered when an export action is performed. I confirmed by adding a print statement.

How should I do this?

You are quite close, the only problem is that the actions have reference to the one defined in the ExportActionMixin, so you can override whatever you want, it is not going to refer to your method. You can however override that to to get the right action, so:

from django.utils.translation import gettext as _


class RegAdmin(ExportActionMixin, admin.ModelAdmin):
    # …
    
    def get_actions(self, request):
        actions = super().get_actions(request)
        actions.update(
            export_admin_action=(
                RegAdmin.export_admin_action,
                'export_admin_action',
                _('Export selected %(verbose_name_plural)s'),
            )
        )
        return actions

Update: I've opened a pull request ^[GitHub] to fix this behavior.
