# resolveRailsRoutes

**Kind:** Function

**Source:** [`atloria-monorepo/libs/parser-core/src/techdocs/cross-file-routes.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/techdocs/cross-file-routes.ts#L931)

Prefix a Rails routes file that another routes file `draw`s in.

`draw(:api)` loads `config/routes/api.rb`, and the prefix in force at the draw site lives in
`config/routes.rb`. A drawn file normally opens its own `namespace`, so its local paths are
already right and stay untouched — this only fires where the draw is genuinely nested, which
is the one case the drawn file cannot know about itself.

## Signature

```ts
function resolveRailsRoutes(entities: Entity[]): number
```

## Parameters

| Name | Type |
|---|---|
| `entities` | `Entity[]` |

**Returns:** `number`
