具有多个外键的 Django 内联表单

我正在尝试在我的模板中使用 Django 的 ModelForm 和内联表单。但是，我找不到任何文档可以整齐地映射到具有多个外键的数据库模型回到同一个表。这些是我的模型：

# models.py

class Universities(models.Model):
    name = models.CharField(max_length=100)

class Majors(models.Model):
    name = models.CharField(max_length=80)

class Resumes(models.Model):
    name = models.CharField(max_length=70)
    undergrad = models.ForeignKey(Universities, related_name='undergrad_university')
    undergrad_major = models.ForeignKey(Majors, related_name='undergrad_major')
    grad = models.ForeignKey(Universities, related_name='grad_university')
    grad_major = models.ForeignKey(Majors, related_name='grad_major')

我怎样才能让 Django 生成一个用于提交简历的表单，用户可以在其中输入他们的大学名称和专业？所有四个都将用于在保存新简历之前在各自的数据库中创建新条目（2 个在大学中，2 个在专业中），类似于内联表单集示例适用于单个外键。

EDIT2：用于制作表格。我想我会通过重写 save() 方法来完成个性化表单，如下所示（forms.py）：

class YourForm(forms.Form):
    fname = forms.CharField(label="name",max_length=70,validators=[#Choose your validators here])
    fundergrad = forms.CharField(label="fundergrad",max_length=100,validators=[#Choose your validators here])
    fundergrad_major = forms.CharField(label="fundergrad_major",max_length=80,validators=[#Choose your validators here])
    fgrad = forms.CharField(label="fgrad",max_length=100,validators=[#Choose your validators here])
    fgrad_major = forms.CharField(label="fgrad_major",max_length=80,validators=[#Choose your validators here])

    def save(self, datas):
        res = Resumes()
        res.name = datas['fname']
        
        undergrad = Universities()
        undergrad_major = Majors()
        grad = Universities()
        grad_major = Majors()
        
        undergrad.name = datas['fundergrad']
        undegrad_major.name = datas['fundergrad_major']
        grad.name = datas['fgrad']
        grad_major.name = datas['fgrad_major']
    
        undergrad.save()
        undergrad_major.save()
        grad.save()
        grad_major.save()
    
        res.undergrad = undergrad
        res.undergrad_major = undergrad_major
        res.grad = grad
        res.grad_major = grad_major
    
        res.save()
        return res

在views.py中：

def formView(request) :
  if request.method == 'POST':
      form = YourForm(request.POST)
      if form.is_valid():
          datas={}
          datas['fundergrad']=form.cleaned_data['fundergrad']
          datas['fundergrad_major']=form.cleaned_data['fundergrad_major']
          datas['fgrad']=form.cleaned_data['fgrad']
          datas['fgrad_major']=form.cleaned_data['fgrad_major']

          form.save(datas)

  #Then do what you have to do in your view
  

编辑1：（没有回答问题，但它可能对某人有帮助，所以我把它放在这里）

我会在 admin.py 中尝试使用类似的东西：

class UniversitiesInline1(admin.StackedInline):
  model = Universities
  fk_name = "undergrad"

class UniversitiesInline2(admin.StackedInline):
  model = Universities
  fk_name = "grad"

class MajorsInline1(admin.StackedInline):
  model = Majors
  fk_name = "undergrad_major"

class MajorsInline2(admin.StackedInline):
  model = Majors
  fk_name = "grad_major"

class ResumesAdmin(admin.ModelAdmin)
  inlines = [
    UniversitiesInline1,
    UniversitiesInline2,
    MajorsInline1,
    MajorsInline2,
  ]

admin.site.register(Resumes, ResumesAdmin)
