如何阻止 ruff linter 将导入移动到 TYPE CHECKING if 块中？

Question

我有一个 pydantic 基本模型，看起来像：

from pathlib import Path
from pydantic import BaseModel


class Model(BaseModel):
    log_file: Path

我的 ruff 预提交钩子正在将其重新排序为：

from typing import TYPE_CHECKING
from pydantic import BaseModel

if TYPE_CHECKING:
    from pathlib import Path


class Model(BaseModel):
    log_file: Path

这导致了错误：

pydantic.errors.ConfigError: field "log_file" not yet prepared so type is still a ForwardRef, you might need to call Model.update_forward_refs()

我不想这样做。我怎样才能阻止 ruff 像这样重新订购进口？我的

.pre-commit-config.yaml

文件如下所示：

repos:
  - repo: https://github.com/charliermarsh/ruff-pre-commit
    rev: "v0.0.291"
    hooks:
      - id: ruff
        args: [--fix, --exit-non-zero-on-fix]
  - repo: https://github.com/psf/black
    rev: 23.9.1
    hooks:
      - id: black
        language_version: python3

和我的

pyproject.toml

文件：

[tool.black]
line-length = 120
include = '\.pyi?$'
exclude = '''

'''


[tool.ruff]
line-length = 120
ignore = ["F405", "B008"]
select = ["E", "F", "B", "C4", "DTZ", "PTH", "TCH", "I001"]
# unfixable = ["C4", "B"]
exclude = ["docs/conf.py", "Deployment/make_deployment_bundle.py"]

[tool.ruff.per-file-ignores]
"**/__init__.py" = ["F401", "F403"]

[tool.ruff.isort]
split-on-trailing-comma = true
known-first-party = ["influxabart"]
no-lines-before = ["local-folder"]

section-order = ["future","standard-library","third-party","first-party","this","local-folder"]

[tool.ruff.isort.sections]
"this" = ["InfluxTools"]

Answer 1

尚未重现此问题，但我认为您的

select

选项列表导致了此问题。我知道这不是 ruff 的默认行为。

select = ["E", "F", "B", "C4", "DTZ", "PTH", "TCH", "I001"]

尽管官方自述文件说

TC*

是flake8类型检查的代码，这个问题暗示

TCH*

是。

来自自述文件：

TC001   Move application import into a type-checking block
TC002   Move third-party import into a type-checking block
TC003   Move built-in import into a type-checking block

所以

TC003

就是发生在你身上的事情。或者

TCH003

就是我猜 ruff 所说的。

所以我认为解决方案是从

"TCH"

中的

select

中删除

pyproject.toml

字段。
