请求时出错
Django版本:1.3.1
异常类型:TypeError
例外价值:
init ()至少需要2个参数(给定1个)

您无法在字段声明中使用request.user启动store字段。您可以尝试以下方法:
class MyAwesomeForm(forms.ModelForm):
store = forms.ModelChoiceField(Store.objects)
class Meta:
model = Promo
def __init__(self, user, *args, **kwargs):
super(MyAwesomeForm, self).__init__(*args, **kwargs)
self.fields['store'].queryset = Store.objects.filter(owner=user)
在实例化表单时,您可以传递request.user对象。
myform = MyAwesomeForm(request.user)
如果您想在管理员中实现这一目标,可以尝试this 为了在管理员中仅提供与登录用户相关的对象,可以覆盖ModelAdmin.queryset函数:
class MyModelAdmin(admin.ModelAdmin):
form = MyAwesomeAdminForm()
def queryset(self, request):
qs = super(MyModelAdmin, self).queryset(request)
if request.user.is_superuser:
return qs
return qs.filter(store__owner=request.user)
class MyAwesomeAdminForm(forms.ModelForm):
class Meta:
model = Promo
请注意,store__owner仅在您的促销模型中存储了外键字段时才有效:
class Promo(models.Model):
store = models.ForeignKey(Store)
class Store(models.Model):
owner = models.ForeignKey(User)
我认为也应该可以以某种方式将请求传递给表单的init方法。但没有找到合适的方法来做到这一点。
