# Migration
|
|
|
|
### Adding new migration
|
|
|
|
1. The project used rockerhopper for db migration.
|
|
https://github.com/c9s/rockhopper
|
|
|
|
|
|
2. Create migration files
|
|
|
|
|
|
You can use the util script to generate the migration files:
|
|
|
|
```
|
|
bash utils/generate-new-migration.sh add_pnl_column
|
|
```
|
|
|
|
Or, you can generate the migration files separately:
|
|
|
|
```sh
|
|
rockhopper --config rockhopper_sqlite.yaml create --type sql add_pnl_column
|
|
rockhopper --config rockhopper_mysql.yaml create --type sql add_pnl_column
|
|
```
|
|
|
|
|
|
Be sure to edit both sqlite3 and mysql migration files. ( [Sample](.../../migrations/mysql/20210531234123_add_kline_taker_buy_columns.sql) )
|
|
|
|
To test the drivers, you have to update the rockhopper_mysql.yaml file to connect your database,
|
|
then do:
|
|
|
|
```sh
|
|
rockhopper --config rockhopper_sqlite.yaml up
|
|
rockhopper --config rockhopper_mysql.yaml up
|
|
```
|
|
|
|
Then run the following command to compile the migration files into go files:
|
|
|
|
```shell
|
|
make migrations
|
|
```
|
|
|
|
or
|
|
|
|
```shell
|
|
rockhopper compile --config rockhopper_mysql.yaml --output pkg/migrations/mysql
|
|
rockhopper compile --config rockhopper_sqlite.yaml --output pkg/migrations/sqlite3
|
|
git add -v pkg/migrations && git commit -m "compile and update migration package" pkg/migrations || true
|
|
```
|
|
|
|
|
|
If you want to override the DSN and the Driver defined in the YAML config file, you can add some env vars in your dotenv file like this:
|
|
|
|
```shell
|
|
ROCKHOPPER_DRIVER=mysql
|
|
ROCKHOPPER_DIALECT=mysql
|
|
ROCKHOPPER_DSN="root:123123@unix(/opt/local/var/run/mysql57/mysqld.sock)/bbgo"
|
|
```
|
|
|
|
And then, run:
|
|
|
|
```shell
|
|
dotenv -f .env.local -- rockhopper --config rockhopper_mysql.yaml up
|
|
```
