Question

我尝试使用特殊配置检查我的代码 .pre-commit-config.yaml 仓库：

回购：https://github.com/ambv/black rev：“稳定” 钩子：
- id：黑色 args：[-py36，-line-length = 120，src / webhook_app] python版本：python3.6
回购：https://github.com/pre-commit/mirrors-mypy 修订版：v0.630 钩子：
- id：mypy args：[--no-strict-optional，-ignore-missing-imports]
回购：https://github.com/pre-commit/pygrep-hooks 版本：v1.1.0 钩子：
- id：python-use-type-annotations

回购：https://github.com/pre-commit/mirrors-pylint 版本：v1.9.1 钩子：

id：pylint

    args: [
      --max-line-length=120,
      --disable=design,
      --disable=missing-docstring,
      --disable=bad-continuation,
      --disable=max-module-lines,
      --disable=useless-super-delegation,
      --disable=import-error,
      --disable=logging-fstring-interpolation,
      --disable=invalid-name,
      --disable=duplicate-code
    ]
    # exclude tests folder and manage.py to be checked
    exclude: 'tests|manage.py'```

回购：https://github.com/pre-commit/pre-commit-hooks 版本：v1.4.0 钩子：
- id：flake8 args：['-max-line-length = 120']
- id：尾随空白

我开始检查我的代码

import warnings
from contextlib import contextmanager
from enum import Enum

from sqlalchemy import create_engine
from sqlalchemy import exc
from sqlalchemy.ext.declarative import DeferredReflection, declarative_base
from sqlalchemy.inspection import inspect
from sqlalchemy.orm import scoped_session, sessionmaker

import structlog


logger = structlog.get_logger(__name__)


class Base(DeferredReflection, declarative_base()): # type: ignore

    """ Abstract base class for construction of mappings
    based on a deferred reflection step.
    All classes inherited from it will be reflected by the time
    of calling DeferredReflection.prepare()""" 

    __abstract__ = True

    def __repr__(self):
        inspector = inspect(self.__table__)
        return "{}({})".format(
            self.__class__.__name__,
            ", ".join("%s=%s" % (column.name, self.__dict__[column.name]) for column in inspector.columns),
        )

我收到来自hookid: python-use-type-annotations的错误消息

src/webhook_app/models.py:17:class Base(DeferredReflection, declarative_base()):  # type: ignore

当我删除# type: ignore时python-use-type-annotations表示一切正常，但是mypy向我发送了一个错误Invalid base class。

能请你帮我吗？

Answer 1

我认为您没有正确使用declarative_base()。

Base = declarative_base(cls=DeferredReflection)

class MyClass(Base):
    ...

或

Base = declarative_base()

class MyClass(DeferredReflection, Base):
    ...

python的自动代码检查不正确
