Migrations and Factories

Keep schema changes safe, testable, and reversible.

Commands

php artisan make:model Post -mfc

# Run/rollback
php artisan migrate
php artisan migrate:rollback --step=1

# Fresh DB (dangerous; dev only)
php artisan migrate:fresh --seed

Rules

Pair each new model with a migration and a factory
If a migration was merged to
```
main
```
, never edit it—add a new one
On feature branches, you may amend migrations created on that branch (if not merged)
Seed realistic but minimal datasets in seeder classes; keep huge datasets external

Factories

Prefer state modifiers (e.g.,
```
->state([...])
```
) over boolean flags
Use relationships (e.g.,
```
belongsTo
```
) in factories to build realistic graphs
Keep factories fast; move expensive setup to seeds where possible

Testing

Use factories in tests; avoid manual inserts
For integration tests touching DB, use transactions or
```
RefreshDatabase
```
