Django內嵌表單與多個外鍵

Question

我想在我的模板中使用Django的ModelForm和內聯表單。但是，我找不到任何將多個外鍵整齊映射到數據庫模型的文檔返回到同一個表。這是我的模型：

# 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') 

我怎麼能有Django的生成提交簡歷，用戶可以輸入自己的大學名稱和主要形式？在保存新簡歷之前，所有這四項都將用於在其各自的數據庫中創建新條目（大學中有2個，專業中有2個），類似於inline formset example如何用於單一外鍵。

編輯2：對於一個形式。我想我已經做了有）保存的壓倒一切的（方法，像這樣（forms.py）個性化的形式：

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：

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 

EDIT1：（沒有按「T回答的問題，但它可以幫助別人，也許只好讓在這裏）

我會在admin.py像這樣嘗試：

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)
