def test_create_user(client):
    test_user = {"email": "******@****.***", "password": "secret"}
    response = client.post("/users/", json=test_user)
    assert response.status_code == 200, response.text
    data = response.json()
    assert test_user["email"] == data["email"]
    assert "id" in data
    response = client.post("/users/", json=test_user)

def test_create_user(client):
    test_user = {"email": "******@****.***", "password": "secret"}
    response = client.post("/users/", json=test_user)
    assert response.status_code == 200, response.text
    data = response.json()
    assert test_user["email"] == data["email"]

    response = client.post("/users/", json=test_user)

def test_create_user(client):
    test_user = {"email": "******@****.***", "password": "secret"}
    response = client.post("/users/", json=test_user)
    assert response.status_code == 200, response.text
    data = response.json()
    assert test_user["email"] == data["email"]
    assert "id" in data
    response = client.post("/users/", json=test_user)

```

就会生成如下结果：

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

或更精准，直接把可能会用到的内容与 `user_dict` 一起使用：

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### 用其它模型中的内容生成 Pydantic 模型

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Oder, präziser, `user_dict` wird direkt verwendet, welche Werte es auch immer haben mag:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

もっと正確に言えば、`user_dict`を将来的にどんな内容であっても直接使用することになります:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```
