### Target language

Translate to French (français).

Language code: fr.

### Grammar to use when talking to the reader

Use the formal grammar (use `vous` instead of `tu`).

Additionally, in instructional sentences, prefer the present tense for obligations:

- Prefer `vous devez …` over `vous devrez …`, unless the English source explicitly refers to a future requirement.

	if err := DB.Create(&user).Error; err != nil {
		t.Fatalf("errors happened when create: %v", err)
	}

	if err := DB.Model(&user).Association("Languages").Replace(Language{Name: "DE", Code: "de"}, Language{Name: "FR", Code: "fr"}); err != nil {
		t.Error("expected association error to be not nil")
	}

	var result User
	DB.Preload("Languages").Where("name = ?", "HasManyAssociationReplaceWithStructValue").Find(&result)

Find the `supported.languages` property (around line 202) and ensure your language code is included:

```properties
supported.languages=ar,bg,bn,ca,ckb_IQ,cs,da,de,el,en_IE,en,es,et,eu,fa,fi,fr,gl,gu,he,hi,hr,hu,hy,id,it,ja,ko,lt,lv,mk,ml,nl,no,pa,pl,pt_BR,pt,ro,ru,si,sq,sv,ta,te,th,tl,tr,uk,ur,vi,zh_CN,zh_TW,zh
```

**Optional configurations:**
