Question

我有一个网页包含一个工作请求和inlinformset为可能的候选人设置一个按钮来设置面试工作正常。对于每个候选人，对于相同的工作请求，应该有一次或多次面试。当用户点击面试按钮时，他将被转移到另一个页面，用于采访URL Para作为工作申请ID（jid）和候选ID（cid），如下所示

class InterviewForm(ModelForm):
  class Meta:
    model = Interview 
    exclude = ()

InterviewFormSet = modelformset_factory(Interview,form=InterviewForm, extra=1)

面试模型

class Interview(models.Model): 
  jobRequisition = models.ForeignKey(JobRequisition, on_delete=models.PROTECT)
  interviewer = models.ManyToManyField(Employee) 
  candidate = models.ForeignKey(Candidate, on_delete=models.PROTECT)
  interview_date =  models.DateField( blank = True)
  interview_type = models.CharField(max_length=150, choices= interview_type )

视图：

class InterviewCreate(CreateView):
  model =  Interview
  form_class = InterviewForm
  success_url = reverse_lazy('jobRequisitions-list') 

  def get_context_data(self, **kwargs):
    # bring all interviews related to the selected candidate and job request
    qu = Interview.objects.filter(jobRequisition=self.kwargs['jid'], candidate=self.kwargs['cid'])
    context = super(InterviewCreate, self).get_context_data(**kwargs)
    if self.request.POST:
        context['candidateinterviews'] = InterviewFormSet(self.request.POST)
    else:
        context['candidateinterviews'] = InterviewFormSet(queryset=qu)
    return context

我的问题： 1-无法保存：当我点击保存按钮时，我收到一些错误来填写缺失的数据，因此，验证工作正常，但在此之后，我无法将数据保存在表单集中。我曾尝试使用＆＃34; def form_valid（self，form）：print（＆＃34;我在这里＆＃34;）＆＃34;但似乎代码没有进入这个功能，它总是得到form_invalid。

2- url para中的默认值：我想隐藏用户的候选人姓名和工作申请号，当他点击“保存”时，这些数据将从网址中自动提取并与其他条目一起保存。我可以从url获取para，但是我无法将它们附加到formst并将它们保存到数据库中。

更新后的视图：

def InterviewCreate(request, jid, cid):
  jobRequisitions_url = '/recruitment_single_company/jobRequisitions/' + str(jid)   
  if request.method == "POST":
    candidateinterviews = InterviewFormSet(request.POST, request.FILES) 
    if(candidateinterviews.is_valid()):
        candidateinterviews.save()
        return HttpResponseRedirect(jobRequisitions_url)    
    else:
        print ("Something went wrong"   )
  else:
    candidateinterviews = InterviewFormSet(queryset=Interview.objects.filter(jobRequisition=jid, candidate=cid))
  return render(request, 'recruitment_single_company/interview_form.html', {'formset': candidateinterviews})

到目前为止，只要我手动输入job_id和candidate_id作业，代码就会消失，但是我希望隐藏这两个文件并在表单有效时保存它们。
我已经尝试在上面的代码中替换前一行并添加了初始数据（如下所示）并且它工作正常，但是当我想使用＆＃34时排除两个fieldes;排除＆＃34;我无法保存表单。我可以隐藏那些不包括它们的字段吗？

candidateinterviews = InterviewFormSet(queryset=Interview.objects.filter(jobRequisition=jid, candidate=cid), initial=[{'jobRequisition': jid, 'candidate': cid,}])

以下是我的最终观点，我正在使用jquery.formset.js

def InterviewCreate(request, jid, cid):
  jobRequisitions_url = '/recruitment_single_company/jobRequisitions/' + str(jid)   

  if "cancel_btn" in request.POST: # if user click cancel/back button then it will go to previous page
    return HttpResponseRedirect(jobRequisitions_url) 

  if request.method == "POST":
    candidateinterviews = InterviewFormSet(request.POST, request.FILES) 
    if candidateinterviews.is_valid() and candidateinterviews.has_changed():
        for form in candidateinterviews:
            interview_date = form.cleaned_data.get('interview_date')
            if form.cleaned_data.get('DELETE') and form.cleaned_data.get('id') != None:
                interview_id = form.cleaned_data.get('id').id
                Interview.objects.filter(id=interview_id).delete()
            # Belw is my way to do extra validation, without it Django will try to save data
            # even if there is no change and it will give the below error:
            # The Interview could not be created because the data didn't validate.     
            elif interview_date != None:
                obj = form.save(commit=False) # we need this because we have excluded fields in the form
                obj.jobRequisition_id = jid # manually save the foreign key for job requestion
                obj.candidate_id = cid # manually save the foreign key for candidate
                obj.save()
                form.save_m2m() # we need this since we have many to many fields
    else:
        candidateinterviews = InterviewFormSet(queryset=Interview.objects.filter(jobRequisition=jid, candidate=cid))
  else:
    candidateinterviews = InterviewFormSet(queryset=Interview.objects.filter(jobRequisition=jid, candidate=cid))

  return render(request, 'recruitment_single_company/interview_form.html', {'candidateinterviews': candidateinterviews})

另外，我更新了InterviewForm以隐藏两列

class InterviewForm(ModelForm):
  class Meta:
    model = Interview 
    exclude = (['jobRequisition', 'candidate'] )

InterviewFormSet = modelformset_factory(Interview, form=InterviewForm, extra=1, can_delete=True)

Django模型formset无法保存
