我只想在特定的灯具中展示与球队相关的球员。通常当我这样做时,它会向我显示数据库中的所有玩家。这是我的models.py
class InningsCard(models.Model):
fixture = models.ForeignKey(Fixture)
team = models.ForeignKey(Team)
runs = models.IntegerField(max_length=6, default=0)
wickets = models.IntegerField(max_length=6, default=0)
overs = models.FloatField(max_length=6, default=0.0)
def __unicode__(self):
return str(self.team)
class BattingDetail(models.Model):
STATUS_CHOICES = (
('no', 'not out'),
('bowled', 'bowled'),
('caught', 'caught'),
('lbw', 'lbw'),
)
innings = models.ForeignKey(InningsCard)
player = models.ForeignKey(Player)
runs = models.IntegerField(max_length=5, default=0)
status = models.CharField(max_length=15, choices=STATUS_CHOICES, default='no')
def __unicode__(self):
return str(self.player)
现在,这是我的admin.py包含formfield_for_foreignkey,但它不起作用。
class BattingInline(admin.TabularInline):
model = BattingDetail
extra = 0
def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
if db_field.name == 'player':
kwargs = Player.objects.filter(team = request.team)
else:
pass
return super(BattingInline, self).formfield_for_foreignkey(db_field, request, **kwargs)
class InningCardAdmin(admin.ModelAdmin):
inlines = [BattingInline]
我哪里可能出错?

答案 0 :(得分:8)
您正在使用查询集替换整个kwargs
。 kwargs
必须是字典,您要查找的特定键是“queryset”:
kwargs['queryset'] = Player.objects.filter(team=request.team)
我几乎是肯定的请求实际上没有属性team
。除非你自己在这里没有显示的代码中添加它,否则你需要找到另一种方法来获得当前的“团队”。例如,您可以从request.path
解析出团队ID,并将其用于查找。
作为旁注,如果您只是前往else
,则不需要pass
