Is it expected behavior for PyCharm to be unable to refactor a Python enum member decorated with @unique?

PyCharm 2022.3.1, Build #PY-223.8214.51, assembled on December 20, 2022

Python 3.10.6

When an enum is marked with the @unique decorator and is defined in a separate file, PyCharm seems to have difficulty finding usages for refactoring or renaming. It also does not provide contextual options for refactoring or renaming.

Declaration:

# file: pycharm_enum_dec.py

from enum import Enum, unique


@unique
class MyType(Enum):
    AAA = 'aaa'
    BBB = 'bbb'

Usage:

# file: pycharm_refac_enum.py

from pycharm_enum_dec import MyType

print(MyType.AAA)

Is this issue related to the @unique decorator itself or is it a bug within PyCharm?

Answer №1

According to IntelliJ, there is a known issue with how PyCharm handles the @unique decorator. The team has acknowledged the problem and is working on fixing it, although there is currently no estimated time for when this will be resolved (as of January 17, 2023).
