这是我的模型和管理类：

return '%s' % (self.id)

我正在尝试实现django-select2，但是当我在其中使用内联时，
PurchaseOrderAdmin它不会显示我已实现的字段
django-select2：
但是当我删除内联时，它工作正常：
编辑
这是 ItemSelectForm
class ItemSelectForm(forms.ModelForm):
class Media:
js = (

filter(parent__parent__isnull=True).filter(parent__isnull=False))

sub_category_choices = [('', '--------')] + [(id, name) for id, name in
itertools.izip(sub_category_id, sub_category_name)]
sub_category = forms.ChoiceField(sub_category_choices)
except:

item = forms.ModelChoiceField(queryset = Product.objects.all())
