</Table>

### Retrieve with Query

To retrieve the translations of a product with [Query](!docs!/learn/fundamentals/module-links/query), pass `translations.*` in `fields`:

<Note>

You can pass the `translations.*` field when querying any of the above-mentioned data models to retrieve their associated translations.

</Note>

<CodeTabs group="relation-query">
  <CodeTab label="query.graph" value="method">

```ts
const { data: products } = await query.graph({
  entity: "product",
  fields: [
    "translations.*",
  ],
})

// products[0].translations
```

  </CodeTab>
  <CodeTab label="useQueryGraphStep" value="step">

```ts
import { useQueryGraphStep } from "@medusajs/medusa/core-flows"

// ...

const { data: products } = useQueryGraphStep({
  entity: "product",
  fields: [
    "translations.*",
  ],
})

// products[0].translations
```

  </CodeTab>
</CodeTabs>

## Store Module

The [Store Module](../../store/page.mdx) has a `StoreLocale` data model that stores the supported locales of a store. However, these locales don't hold all the details of a locale, such as its name.

Instead, Medusa defines a read-only link from the Store Module's `StoreLocale` data model to the Translation Module's `Locale` data model. This means you can retrieve the details of a store's supported locales, but you don't manage the links in a pivot table in the database.

### Retrieve with Query

To retrieve the details of a store's locales with [Query](!docs!/learn/fundamentals/module-links/query), pass `supported_locales.locale.*` in `fields`:

<CodeTabs group="relation-query">
  <CodeTab label="query.graph" value="method">

```ts
const { data: stores } = await query.graph({
  entity: "store",
  fields: [
    "supported_locales.locale.*",
  ],
})

// stores[0].supported_locales[0].locale
```

  </CodeTab>
  <CodeTab label="useQueryGraphStep" value="step">

```ts
import { useQueryGraphStep } from "@medusajs/medusa/core-flows"

// ...

const { data: stores } = useQueryGraphStep({
  entity: "store",
  fields: [
    "supported_locales.locale.*",
  ],
})

// stores[0].supported_locales[0].locale
```

  </CodeTab>
</CodeTabs>
