python - Django AttributeError：“ InterestsForm”对象没有属性“ _errors”

我试图使用django表单来允许django用户输入他们最喜欢的三个兴趣。该错误在模板呈现过程中出现，并显示{{form.as_ul}}。
代码如下：
注册兴趣.html

{% block content %}

<br><br>
<h1>Choose the 3 things that interest you most!</h1>

<form method="post" action="/reg_interests/">
    {% csrf_token %}
    {{form.as_ul}}
    <br>
    <p class="submit"><input  class="btn btn-default" type="submit" name="commit" value="Continue"></p>
</form>

{% endblock %}

def reg_interests_view(request):
    if request.POST:
        form = InterestsForm(request.POST, request=request)
        if form.is_valid():
            form.save(request)
            return redirect('/reg_video/')

    args = {}
    args['form'] = InterestsForm(request=request)

    return render(request, 'login/reg_interests.html', args)

class InterestsForm(RequestModelForm):
    interest1 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])
    interest2 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])
    interest3 = forms.ChoiceField(choices=[(1, "Option 1"), (2, "Option 2")])

    class Meta:
        model = Interest
        fields = ('interest1', 'interest2', 'interest3')

    def __init__(self, request):
        self.user = request.user

    def save(self, commit=True):
        interest = super(InterestsForm, self).save(commit=False)
        interest.user = self.user
        interest.interest1 = self.cleaned_data['interest1']
        interest.interest2 = self.cleaned_data['interest2']
        interest.interest3 = self.cleaned_data['interest3']

        if commit:
            interest.save()

        return interest

最佳答案：

这段代码根本不可能工作，因为您重写了窗体的__init__方法，因此a）您只接受了request参数，而不接受窗体所期望的任何其他东西，如data或initial-和b）您从不调用超类init方法来初始化窗体代码其余部分所期望的东西你需要保留签名并打电话给super。

def __init__(self, *args, **kwargs):
     request = kwargs.pop('request')
     self.user = request.user
     super(InterestsForm, self).__init__(*args, **kwargs)
