python - Django 不一致迁移历史

问题描述

我正在尝试设置一个 Django 项目，但遇到以下错误：

WARNINGS:
?: (rest_framework.W001) You have specified a default PAGE_SIZE pagination rest_framework setting,without specifying also a DEFAULT_PAGINATION_CLASS.
    HINT: The default for DEFAULT_PAGINATION_CLASS is None. In previous versions this was PageNumberPagination. If you wish to define PAGE_SIZE globally whilst defining pagination_class on a per-view basis you may silence this check.
Traceback (most recent call last):

make: *** [migrate] Error 1

我在虚拟环境中运行它，并且有一个用于运行 postgres 数据库的 docker-compose 容器。不知道如何开始调试它或它为什么会发生。任何帮助，将不胜感激

解决方案

在项目内的迁移文件夹中执行以下步骤：

删除pycache和0001_initial 文件。

从根目录中删除 db.sqlite3（注意所有数据都会消失）。在终端运行：

python manage.py makemigrations
python manage.py migrate

注意：不要忘记备份您的数据。
