```bash
|
|
poetry install

```
|
|
|
|
- **run for mysql:** ```docker compose -f docker-compose.mysql.yaml up```
|
|
|
|
- **run for postgres:** ```docker compose -f docker-compose.postgres.yaml up```
|
|
|
|
- **run initial data:**
|
|
```bash
|
|
cd src
|
|
python /data/fill_data.py
|

|
## Run all in docker:
|

## Help info:

|
|
### Create alembic migrations:
|
|
|
|
*Note: To generate migrations you should run:*
|
|
```bash
|
|
# For automatic change detection.
|
|
alembic revision --autogenerate -m "migration message"
|
|
|
|
# For empty file generation.
|
|
alembic revision
|
|
```
|
|
|
|
*Note: If you want to migrate your database, you should run following commands:*
|
|
```bash
|
|
# To run all migrations untill the migration with revision_id.
|
|
alembic upgrade "<revision_id>"
|
|
|
|
# To perform all pending migrations.
|
|
alembic upgrade "head"
|
|
```
|
|
|
|
### Reverting alembic migrations:
|
|
|
|
*Note: If you want to revert migrations, you should run:*
|
|
```bash
|
|
# revert all migrations up to: revision_id.
|
|
alembic downgrade <revision_id>
|
|
|
|
# Revert everything.
|
|
alembic downgrade base
|
|
|
|
# Revert N revisions.
|
|
alembic downgrade -2
|
|
```
|
|
|
|
### MySQL database access:
|
|
|
|
Postgres:
|
|
```bash
|
|
docker exec -it sqlalchemy_study_db psql -d sqlalchemy_study -U balsh
|
|
```
|
|
|
|
- show help ```\?```
|
|
- show all tables: ```\dt```
|
|
- describe table ```\d {table name}```
|
