# Working with symfony database

## Setting up a Database table

### Part 1 - Entity Class

```bash
php bin/console make:entity
```
And then follow the instructions.

This will create a entity class in src/Entity

**Note: ** You can run make:entity again with the same Entity name to add more fields.
You will have to run make:migration and then doctrine:migrations:migrate

The system is smart enough not to duplicate work.

## Part 2 - Create Migration

To create a migration from the entity, run:

```bash
sudo docker-compose run php bin/console make:migration
```

A file will be created in the migrations folder.

## Part 3 - Create the table (run migration)

```bash
sudo docker-compose run php php bin/console doctrine:migrations:migrate
```
