Karen,
Thanks for your help. Here's what I've done:
I've commented out the list_display for GameAdmin and defined a
__unicode__ for game as:
def __unicode__(self):
return '%s vs. %s' % (self.team.name, self.opponent)
That returns values in the admin display as "Team 1 vs. Team 2", etc.,
as we would have hoped.
Uncommenting the list_display as so:
class GameAdmin(admin.ModelAdmin):
list_display = ('team', 'opponent',)
search_fields = ('team__name','opponent',)
results in the strange behavior (non-zero count but showing no rows)
changing list display to team__name results in the following error:
'team__name' is not a callable or an attribute of 'GameAdmin' or found
in the model 'Game'.
So now that I copied that and pasted that error message here, I have a
thought: make a callable for Game as:
def _team_name(self):
return (self.team.name)
team_name = property(_team_name)
class GameAdmin(admin.ModelAdmin):
list_display = ('team_name', 'opponent',)
search_fields = ('team__name','opponent',)
Everything now displays correctly. Reading the documentation on
list_display and Abstract classes, I assumed that I could reference
Team elements through the AbstractEvent model. Apparently, that is
not the case. The callable seems to have solved my problem.
Thanks for your help!
