Hello all,
I have these classes:
class Screen(rdb.Model):
"""Represents the screen"""
rdb.metadata(metadata)
rdb.tablename("screens")
id = Column("id", Integer, primary_key=True)
title = Column("title", String(100))
......
crm = relationship("CRM", uselist=False, backref="screens")
class CRM(rdb.Model):
"""Represents the CRM Tab"""
rdb.metadata(metadata)
rdb.tablename("crms")
id = Column("id", Integer, ForeignKey("screens.id"),
primary_key=True)
title = Column("title", String(50))
contactInformation = relationship("CRMContactInformation",
uselist=False, backref="crms")
endpointConfiguration = relationship("CRMEndpointConfiguration",
uselist=False, backref="crms")
location = relationship("CRMLocation", uselist=False, backref="crms")
slaEvent = relationship("CRMSLAEvent", uselist=False, backref="crms")
notes = relationship("CRMNote", uselist=True, backref="crms")
log = relationship("CRMLog", uselist=True, backref="crms")
I get this error when trying to delele a screen object:
session.delete(screen)
AssertionError: Dependency rule tried to blank-out primary key column
'crms.id' on instance '<CRM at 0xa3a7fac>'
Thanks!
