# HACK: Datamodel-codegen output for enum-type fields with a default is invalid – the default value is a plain string,
# and not the expected enum member. We fix this using sed, which is pretty hacky, but does the job.
# Specifically, we need to replace `Optional[PropertyOperator] = "exact"`
# with `Optional[PropertyOperator] = PropertyOperator("exact")` to make the default value valid.
# Remove this when https://github.com/koxudaxi/datamodel-code-generator/issues/1929 is resolved.
