# Best Practices
1. **Organize migrations**: Run `mix ash.codegen` after each meaningful set of resource changes with a descriptive name:
```bash
mix ash.codegen --name add_user_roles
mix ash.codegen --name implement_post_tagging
```
2. **Use check constraints for domain invariants**: Enforce data integrity at the database level:
```elixir
check_constraints do
check_constraint :valid_status, check: "status IN ('pending', 'active', 'completed')"
check_constraint :positive_balance, check: "balance >= 0"
end
```
3. **Use custom statements for schema-only changes**: If you need to add database objects not directly tied to resources:
```elixir
custom_statements do
statement "CREATE EXTENSION IF NOT EXISTS \"pgcrypto\""
statement "CREATE INDEX users_search_idx ON users USING gin(search_vector)"
end
```
