## Introduction
Tortoise-ORM is the best asyncio ORM now, but it lacks a database
migrations tool like alembic for SQLAlchemy, or Django ORM with it\'s
own migrations tool.
This project aim to be a best migrations tool for Tortoise-ORM and which
written by one of contributors of Tortoise-ORM.
## Install
Just install from pypi:
```shell
> pip install aerich
```
## Quick Start
```shell
$ aerich -h
Usage: aerich [OPTIONS] COMMAND [ARGS]...
Options:
-c, --config TEXT Config file. [default: aerich.ini]
--app TEXT Tortoise-ORM app name. [default: models]
-n, --name TEXT Name of section in .ini file to use for aerich config.
[default: aerich]
-h, --help Show this message and exit.
Commands:
downgrade Downgrade to previous version.
heads Show current available heads in migrate location.
history List all migrate items.
init Init config file and generate root migrate location.
init-db Generate schema and generate app migrate location.
migrate Generate migrate changes file.
upgrade Upgrade to latest version.
```
## Usage
You need add `aerich.models` to your `Tortoise-ORM` config first,
example:
```python
TORTOISE_ORM = {
"connections": {"default": "mysql://root:123456@127.0.0.1:3306/test"},
"apps": {
"models": {
"models": ["tests.models", "aerich.models"],
"default_connection": "default",
},
},
}
```
### Initialization
```shell
$ aerich init -h
Usage: aerich init [OPTIONS]
Init config file and generate root migrate location.
Options:
-t, --tortoise-orm TEXT Tortoise-ORM config module dict variable, like settings.TORTOISE_ORM.
[required]
--location TEXT Migrate store location. [default: ./migrations]
-h, --help Show this message and exit.
```
Init config file and location:
```shell
$ aerich init -t tests.backends.mysql.TORTOISE_ORM
Success create migrate location ./migrations
Success generate config file aerich.ini
```
### Init db
```shell
$ aerich init-db
Success create app migrate location ./migrations/models
Success generate schema for app "models"
```
::: {.note}
::: {.title}
Note
:::
If your Tortoise-ORM app is not default `models`, you must specify
`--app` like `aerich --app other_models init-db`.
:::
### Update models and make migrate
```shell
$ aerich migrate --name drop_column
Success migrate 1_202029051520102929_drop_column.json
```
Format of migrate filename is
`{version_num}_{datetime}_{name|update}.json`
### Upgrade to latest version
```shell
$ aerich upgrade
Success upgrade 1_202029051520102929_drop_column.json
```
Now your db is migrated to latest.
### Downgrade to previous version
```shell
$ aerich downgrade
Success downgrade 1_202029051520102929_drop_column.json
```
Now your db rollback to previous version.
### Show history
```shell
$ aerich history
1_202029051520102929_drop_column.json
```
### Show heads to be migrated
```shell
$ aerich heads
1_202029051520102929_drop_column.json
```
## Limitations
- Not support `rename column` now.
- `Sqlite` and `Postgres` may not work as expected because I don\'t
use those in my work.
## Support this project
- Just give a star!
- Donation.
