我只想在特定的比赛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]
哪里可能出错？
//老鼠
解决方法
>您将使用查询集替换整个kwargs. kwargs必须是字典,你要找的特定键是’queryset’：
kwargs['queryset'] = Player.objects.filter(team=request.team)
>我几乎是积极的请求,实际上并没有属性团队.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中解析出团队ID,并将其用于查找.
作为旁注,如果您要通过那里,则不需要else子句.
