快速入门

在应用升级时，迁移阶段将被转换为提交。`migration.py` 文件应定义一个名为 `Migration` 的变量，可以是 `m` 或 `migration`。

# migration.py

from migrate_code import Migration, get_repo_root

m = Migration("Demonstrate basic usage")

@m.add_stage(1, "Create a new file")
def stage_1():
    (get_repo_root() / "new_file.txt").write_text("Hello world")


@m.add_stage(2, "Create another file")
def stage_2():
    (get_repo_root() / "another_file.txt").write_text("Hello another world")


@m.add_stage("1.1", "Modify the first file")
def stage_1_1():
    (get_repo_root() / "new_file.txt").write_text("Hello world, again")

现在可以轻松创建和重置提交
