A Pydantic provides a class that defines or specifies the structure or format of your data and the validation rules. It must pass to be considered valid which is known as BaseModel. The BaseModel class provides a comprehensive way to define and manage the data models. In this article, we ...

Using Pydantic models, you can ensure smooth and efficient serialization and deserialization of complex data structures. Here’s an example of a Pydantic script for data validation during serialization or deserialization: Python from typing import Optional from pydantic import BaseModel class User(Base...
The script starts by importing the “BaseModel” class from the Pydantic module. This class generates the Pydantic models that define the organized data structures accompanied by validation and parsing functionalities. After importing the required module, we create a structure of the Pydantic model cla...
from pydantic import BaseModel class Query(BaseModel): prompt: str app = FastAPI() @app.get("/") async def root(): return {"message": "Hello!"} @app.post("/query") async def root(query: Query): res = model_query(query=query.prompt) ...

但失败了。要解决此问题，您有两个选择：1.接受表单数据而不是JSON。您可以通过将路由更改为：
Support for data validation: Using the Pydantic BaseModel, FastAPI leverages Python’s data type hints to maintain strictness while parsing data. This prevents the wrong data type from entering the database. Hence, unlike dynamic models requiring extra validation libraries, model validation is straigh...
