当列表项在pydantic模型中发生更改时，如何验证它们？

from pydantic import BaseModel, Field
from typing import List

class MyModel(BaseModel):
    my_list: List[str] = Field(..., min_items=1, max_items=10)

from pydantic import BaseModel, validate
from typing import List

class MyModel(BaseModel):
    my_list: List[str]

    @validate('my_list')
    def validate_my_list(cls, v):
        # 自定义验证逻辑
        if len(v) < 3:
            raise ValueError('列表项数量不能少于3个')
        return v

from pydantic import BaseModel, pre, post
from typing import List

class MyModel(BaseModel):
    my_list: List[str]

    @pre('my_list')
    def preprocess_my_list(cls, v):
        # 预处理逻辑
        return v

    @post('my_list')
    def postprocess_my_list(cls, v):
        # 后处理逻辑
        return v
