Django inlineformset被忽略的额外行

我试图在我的表格中添加额外的行，但它似乎被忽略了。我有一个类似的设置，但没有基本模型。我曾尝试实施该解决方案，但没有成功。有人有办法在我的表单中添加额外的行吗

这是我的密码：

型号.py

class Disease(models.Model):
    disease = models.CharField(max_length=300, verbose_name="disease")

    def __unicode__(self):
      return self.disease


class Indicator(models.Model):
    relevantdisease = models.ForeignKey(Disease, verbose_name="disease")       
    indicator = models.CharField(max_length=300, verbose_name="indicators")

    def __unicode__(self):
      return self.indicator

MAX_INDICATORS = 3

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

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

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

IndicatorFormSet = inlineformset_factory(Indicator,
    IndicatorValue,
    can_delete=False,
    extra=MAX_INDICATORS,
    form=IndicatorForm)

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(reverse(something))

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

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

    relevantdisease = models.ForeignKey(Disease, verbose_name="disease")       
    indicator = models.CharField(max_length=300, verbose_name="indicators")

    def __unicode__(self):
      return self.indicator

MAX_INDICATORS = 3

class DiseaseForm(forms.ModelForm):

视图.py

    disease = models.CharField(max_length=300, verbose_name="disease")

    def __unicode__(self):
      return self.disease


class Indicator(models.Model):

MAX_INDICATORS = 3

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

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

DiseaseFormSet = inlineformset_factory(Disease,

def drui(request):

   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(reverse(something))

   indicatorForm = IndicatorForm()
   diseaseInlineFormSet = DiseaseFormSet()

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

更新代码： 现在，1种疾病将与多个指标相关联，我可以得到额外的线。然而，现在的问题是，每当我保存我的指标并从数据库中选择一种疾病时，一种新的疾病就会写入链接到指标的数据库

Views.py

def drui(request):
if request.method == "POST":

   diseaseForm  = DiseaseForm(request.POST)

   if diseaseForm.is_valid():
      new_disease = diseaseForm.save(commit=False)
      indicatorInlineFormSet = IndicatorFormSet(request.POST, instance=new_disease)

      if indicatorInlineFormSet.is_valid():
         new_disease.save()
         indicatorInlineFormSet.save()
         return HttpResponseRedirect(reverse(valdrui))

else:
   diseaseForm = DiseaseForm()
   indicatorInlineFormSet = IndicatorFormSet(instance=Disease())

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

forms.py

class DiseaseForm(forms.ModelForm):
    disease = forms.ModelChoiceField(queryset=Disease.objects.all())
    class Meta:
       model = Disease

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

IndicatorFormSet = inlineformset_factory(Disease, 
    Indicator,
    can_delete=False,
    extra=MAX_INDICATORS)

在您的视图中，对于单个

指标

实例，您有一个

指标表单

，以及一个

疾病表单集

，用于将多个

疾病

实例绑定到该单个

指标

。然而，在models.py中，您有一个从

指示器到
疾病的
外键
，这意味着
指示器
只能绑定到一个
疾病
实例，而
疾病
实例可以有任意多个
指示器

要解决此问题，请将
外键
从
指示器
模型更改为
疾病
模型，将
疾病
模型更改为
指示器
模型-或者如果您希望改变此模式，坚持使用您现有的型号，并将
指示灯或MSET
与单个
疾病表一起使用
 谢谢你的建议。我选择了后者，并坚持使用模型，以便一种疾病可以有多个指标。然而，出现了一个新的问题，每次提交时都会在数据库表中创建一个新的疾病。我希望能够从数据库中选择与我选择的疾病相关的指标。我以前的解决方案能够做到这一点。嗯，在我看来，你真的希望一个指标有多个疾病，一个疾病有多个指标？使用一个。不管怎样，你能更新你问题中的代码吗？我实际上只想要一种疾病的多个指标（希望这能让事情变得更容易）。我将更新问题中的代码。
