扩展表默默地失败

我已经自定义了一个表单,现在它没有通过is_valid()测试。没有form.errors是可见的。我出错的地方有什么想法吗?

形式:

class SearchForm(forms.Form):
    param = forms.CharField(required=False, max_length = 500, label = 'Search for')
    sets = forms.ModelMultipleChoiceField(queryset=Set.objects.all())    
    onlyDiffer = forms.BooleanField(required=False, label = 'Display varying only') 

    def __init__(self, userN = False, *args, **kwargs):
        super(SearchForm,self).__init__(*args,**kwargs)
        self.userN = userN
        self.fields['sets'].queryset=Set.objects.filter(Q(owner = None) | Q(owner=self.userN))

查看:

def search(request):
    template = 'search.html'
    if request.method == 'POST':
        form = SearchForm(request.POST)
        if form.is_valid():
           (..do search..)
        else:
           return direct_to_template(request, template, {'form' : SearchForm(), 'errors' : form.errors})
    else:
        usr = request.user
        form = SearchForm(usr)
        return direct_to_template(request, template, { 'form': form })

谢谢!

gruzczy有正确的想法,但更好的方法是避免首先更改__init__的函数签名。

def __init__(self, *args, **kwargs):
    self.userN = kwargs.pop('userN', None)
    super(SearchForm,self).__init__(*args,**kwargs)
    ...etc...

这可能是因为您将request.POST传递给userN参数。如果你首先有关键字参数并不意味着,那个request.POST将自动被放入args - 相反,它将被放到userN上。试试这个:

form = SearchForm(False, request.POST)
