django admin后管二级菜单排序

在模型和admin被register之后

apps_index = [yourmodelname]

def find_app_index(app_label):
    app = apps.get_app_config(app_label)
    main_menu_index = getattr(app, 'main_menu_index', 9999)
    return main_menu_index


def index_decorator(func, appname):
    def inner(*args, **kwargs):
        templateresponse = func(*args, **kwargs)
        app_list = templateresponse.context_data['app_list']
        app_list.sort(key=lambda r: find_app_index(r['app_label']))
        for app in app_list:
            print('app', app)
            if app["app_label"] == appname:
                models = app["models"]
                new_models = []
                for i in models:
                    model_name = i["object_name"]
                    pos = apps_index.index(model_name)
                    new_models.append({"pos": pos, "model": i})
                new_models.sort(key=lambda s: s["pos"])
                models = [x["model"] for x in new_models]
                app["models"] = models
        return templateresponse
    return inner
