# Naming and configuration

> Control GraphQL names while keeping Python definitions idiomatic.

`SchemaConfig(auto_camel_case=True)` converts inferred Python names to GraphQL
camel case during schema compilation.

```python theme={null}
from fastql import Field, SchemaConfig, Type, build_schema


@Type
class UserProfile:
    display_name: str
    legacy_code: str = Field(name="legacyID")


schema = build_schema(
    query=QueryRoot,
    config=SchemaConfig(auto_camel_case=True),
)
```

`display_name` becomes `displayName`; the explicit `legacyID` name is preserved.

Naming precedence is:

1. Explicit GraphQL name on `Field`, `Arg`, or a type decorator
2. Inferred Python name transformed by `auto_camel_case`
3. Original Python name when automatic camel case is disabled

Explicit names are appropriate for compatibility contracts. Inferred names reduce
repetition in new schemas.
