Comment:
I also tried reproducing the issue without any success.
Your example is missing the definition of the models you use in the
ForeignKeys, so I had to improvise. Here's what I used:
{{{#!python
class SignalFragment(models.Model):
pass
class ContinuousSignal(models.Model):
last_signal_fragment = models.ForeignKey(SignalFragment)
class AnalysisTicket(models.Model):
pass
class SignalAnalysisTask(models.Model):
continuous_signal = models.ForeignKey(ContinuousSignal,
related_name='signal_analysis_tasks')
closed = models.BooleanField(default=False, db_index=True)
ticket = models.OneToOneField(AnalysisTicket, null=True, blank=True,
related_name='analysis_task')
latest_fragment = models.ForeignKey(SignalFragment, null=True,
blank=True, related_name='analysis_task_latest_fragments')
}}}
I tried running the example you gave with master, 1.5, and even with 1.4
but none of them raised any exception.
In consequence, I'm marking this as `needsinfo`.
Please re-open with more information on how to reproduce the issue.
Thanks.
