我有一个在验证中处理m2m请求的表单。
我的表格如下
class HuntingReportForm(ModelForm):
date_travel_started = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2010)))
date_travel_ended = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2010)))
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, user, *args, **kwargs):
self.validate = kwargs.pop('validate',False)
super(HuntingReportForm, self).__init__(*args, **kwargs)
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', 'report', 'date_travel_started', 'date_travel_ended', 'wish_list', 'bag_list', 'outfitter']
当我删除整个def __init__
部分时,表单似乎验证并保存,但是使用以下代码,它只是让我回到页面上说某些字段没有填写,即使它们是
有什么想法吗?
答案 0 :(得分:1)
您不显示视图,但可能是您使用通常的form = HuntingReportForm(request.POST)
实例化表单。不幸的是,您已将表单的__init__
方法的签名更改为期望user
作为第一个位置参数,因此数据未被传入。您应该将user
移动到kwargs并将其视为与validate
参数相同:
def __init__(self,*args, **kwargs):
user = kwargs.pop('user', None)
self.validate = kwargs.pop('validate', False)
super(HuntingReportForm, self).__init__(*args, **kwargs)
