mypy reports an error in the following code:
import enum from sqlalchemy.ext.declarative import declarative_base from sqlalchemy import Column, Enum Base = declarative_base() class MyEnum(enum.Enum): A = 1 B = 2 class MyTable(Base): __tablename__ = 'my_table' col = Column(Enum(MyEnum), nullable=False) c = MyTable(col=MyEnum.A)
Following is the error:
a.py:16: error: Incompatible type for "col" of "MyTable" (got
"MyEnum", expected "str")
How do I make this error go away without adding a "type: ignore" ? I could also replace MyEnum.A with MyEnum.A.name to make the error go away. But this doesn’t look clean and is also not suggested in sqlalchemy documentation.
