Django管理界面中的只读模型？

Question

如何在管理界面中将模型完全设为只读？它用于一种日志表，我在其中使用管理功能来搜索，排序，过滤等，但无需修改日志。

万一这看起来像是重复的，这不是我想要做的：

• 我不是在寻找只读字段（即使将每个字段都设为只读也可以让你创建新记录）
• 我不是要创建一个只读用户：每个用户都应该是只读的。

class ReadOnlyAdminMixin(object):
    """Disables all editing capabilities."""
    change_form_template = "admin/view.html"

    def __init__(self, *args, **kwargs):
        super(ReadOnlyAdminMixin, self).__init__(*args, **kwargs)
        self.readonly_fields = self.model._meta.get_all_field_names()

    def get_actions(self, request):
        actions = super(ReadOnlyAdminMixin, self).get_actions(request)
        del_action = "delete_selected"
        if del_action in actions:
            del actions[del_action]
        return actions

    def has_add_permission(self, request):
        return False

    def has_delete_permission(self, request, obj=None):
        return False

    def save_model(self, request, obj, form, change):
        pass

    def delete_model(self, request, obj):
        pass

    def save_related(self, request, form, formsets, change):
        pass
