Django表单不接受request.user

Question

我想要获取当前登录用户的信息，也就是想通过用户来筛选内容，比如只获取登录用户的奖杯或者背包列表。

我的表单里有一些不同的元素，如下所示。

class HuntingReportForm(ModelForm):
    date_travel_started = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2012)))
    date_travel_ended = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2012)))
    wish_list = forms.ModelMultipleChoiceField(queryset=Specie.objects.all(), widget=FilteredSelectMultiple("verbose name", is_stacked=False), required=False)
    bag_list = forms.ModelMultipleChoiceField(queryset=Trophies.objects.all(), widget=FilteredSelectMultiple("verbose name", is_stacked=False), required=False)

    class Meta:
        model = HuntingReport
        exclude = ['user',]

    def __init__(self, *args, **kwargs):
        user = kwargs.pop('user', None)
        self.validate = kwargs.pop('validate', False)
        super(HuntingReportForm, self).__init__(*args, **kwargs)

        self.fields['bag_list'].queryset = Trophies.objects.filter(user = self.user)
        users = User.objects.filter(userprofile__outfitter=True)
        self.fields['outfitter'].choices = [('', '')] + [(user.pk, user.get_full_name()) for user in users]
        self.fields.keyOrder = ['title', 'date_travel_started', 'date_travel_ended', 'outfitter', 'wish_list', 'bag_list','report']

任何帮助都非常感谢。

如果你用 HuntingReportFrom(user=request.user) 来初始化表单，这样应该可以正常工作：

 def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user', None)
        self.validate = kwargs.pop('validate', False)
        super(HuntingReportForm, self).__init__(*args, **kwargs)
        self.fields['bag_list'].queryset = Trophies.objects.filter(user = self.user)
