Description (last modified by )
If we work with a field:
regex_flags = models.IntegerField(default=re.UNICODE | re.IGNORECASE)
This is turned into a migration with:
default=re.RegexFlag[None]
This is due to the fact that the EnumSerializer
aims to work with the .name
of the item, but if there is no single item for the given value, then there is no such name.
In that case, we can use enum._decompose
to obtain a list of names, and create an expression to create the enum value by "ORing" the items together.
