python – Django CreateView：将ForeignKey附加到CustomForm数据

我有一个CreateView如下：

class ResumeCreateView(CreateView):
    model = Resume

    def form_valid(self, request, form):
        candidate = Candidate.objects.get(user=self.request.user)
        self.object = form.save(commit=False)
        self.object.candidate = candidate
        self.object.save()
        f = self.request.FILES.get('file')
        data = [{
            'title': self.request['title'],
            'name': f.name,
        }]  
        response = JSONResponse(data, {}, response_mimetype(self.request))
        response['Content-Disposition'] = 'inline; filename=files.json'
        return response

在这里,我试图将候选实例附加到Resume模型候选字段,该字段是Candidate模型的ForeignKey.

但我总是收到验证错误{‘候选人’：’这个字段是必需的’}

>我使用自定义表单而不是模型表单,因为它使用twitter引导标识符.

我错过了什么？

解决方法:

您必须使用候选作为排除字段定义modelForm,然后在form_valid()方法中设置它.

class ResumeForm(forms.ModelForm):
    class Meta:
        model = Resume
        exclude = ('candidate',)

class ResumeCreateView(CreateView):
    form_class = ResumeForm
    model = Resume

    def form_valid(self, form):
        form.instance.candidate = Candidate.objects.get(user=self.request.user)
        ....
