Hi All
ForeignKey and ForeignKeyConstraint copy() method make FK copy without
arguments, for example deferrable, ...
class ForeignKey:
def copy(self, schema=None):
"""Produce a copy of this ForeignKey object."""
return ForeignKey(self._get_colspec(schema=schema))
class ForeignKeyConstraint:
def copy(self, **kw):
return ForeignKeyConstraint(
[x.parent.name for x in self._elements.values()],
[x._get_colspec(**kw) for x in
self._elements.values()],
name=self.name,
onupdate=self.onupdate,
ondelete=self.ondelete,
use_alter=self.use_alter
)
