Django重置migrations

上来就干货！

在任意已经应用的app下创建management/commands/clearmigrations.py文件

import os
import sys
import shutil
from django.core.management.base import BaseCommand
from django.conf import settings
from django.apps import apps


class Command(BaseCommand):
    help = "Clear all migration files in project."

    def get_apps(self):
        for app in apps.get_app_configs():
            # 只删除自己的app下的migrations文件夹
            # path = os.path.join(
            #     settings.BASE_DIR, app.name.replace(".", "/"), "migrations"
            # )

            # 删除所有app,包括虚拟环境app下的migrations文件夹
            path = os.path.join(app.path, "migrations")
            if os.path.exists(path):
                yield app, path

    def handle(self, *args, **options):
        for app, path in self.get_apps():
            # 递归删除所有文件及其路径（删除整个文件夹）
            shutil.rmtree(path)
            # 创建文件夹，并生成__init__.py文件
            os.makedirs(path)
            with open(os.path.join(path, "__init__.py"), "w+") as file:
                file.write("")
            self.stdout.write(self.style.SUCCESS(f"Clear {path}"))

        self.stdout.write(self.style.SUCCESS("Successfully cleared!"))
