html – Django’ManagementForm数据丢失或已经被篡改’当使用外

我对Django很新,所以这可能是一个容易的问题.我有两个modelForms,其中有一个ForeignKey到另一个.我的主要目标是将指标与疾病(FK)联系起来,使得对于特定的疾病,您可以有多个指标.

使用下面的代码,当我点击提交“管理窗体数据丢失或被篡改”时,我收到错误.此外,views.py中的代码似乎没有在第三个’if’语句中返回HttpResponseRedirect的验证.但是,当我检查我的数据库时,表单中的值已写入.任何关于为什么错误提出的想法？以及如何解决？

我的代码如下：

models.py

#Table for Disease
class Disease(models.Model):
    disease = models.CharField(max_length=300)

#Tables for Indicators
class Indicator(models.Model):
    relevantdisease = models.ForeignKey(Disease)       
    indicator = models.CharField(max_length=300)

forms.py

class DiseaseForm(forms.ModelForm):
    class Meta:
      model = Disease

class IndicatorForm(forms.ModelForm):
    class Meta:
      model = Indicator

DiseaseFormSet = inlineformset_factory(Disease,Indicator,can_delete=False,form=DiseaseForm)

views.py

def drui(request):

    if request.method == "POST":

       indicatorForm  = IndicatorForm(request.POST)

       if indicatorForm.is_valid():
          new_indicator = indicatorForm.save()
          diseaseInlineFormSet = DiseaseFormSet(request.POST,request.FILES,instance=new_indicator)

          if diseaseInlineFormSet.is_valid():
             diseaseInlineFormset.save()
             return HttpResponseRedirect('some_url.html')

    else:
       indicatorForm = IndicatorForm()
       diseaseInlineFormSet = DiseaseFormSet()

    return render_to_response("drui.html",{'indicatorForm': indicatorForm,'diseaseInlineFormSet': diseaseInlineFormSet},context_instance=RequestContext(request))

template.html

<form class="disease_form" action="{% url drui %}" method="post">{% csrf_token %}
  {{ indicatorForm.as_table }}
 <input type="submit" name="submit" value="Submit" class="button">
 </form>

{{ diseaseFormSet.as_table }} 
{{ diseaseFormSet.management_form }}
