如何從Django中的模型創建表單字段？

Question

在一個簡單的形式，我有以下類別：

class Upload(models.Model): 
    name = models.CharField() 
    groupy = models.ForeignKey('Group',null=True) 
class Group(models.Model): 
    slogan = models.CharField() 

我現在想創建它同時創建這兩個類的對象的形式。我的方法到目前爲止是：

class GroupCreate(CreateView): 
    def get_form(self, form_class): 
    form = super(GroupCreate, self).get_form(form_class) 
    form.fields['name'] = CharField() 
    return form 
    def form_valid(self, form): 
    response  = super(GroupCreate, self).form_valid(form) 
    groupy  = form.save() 
    upload  = Upload() 
    upload.groupy = groupy 
    upload.name = form.instance.name 
    upload.save() 
    return response 
    ... 

這工作正常。然而，我的問題是，我有很多領域，我需要分別設置每個領域的選項。因此：

我怎麼可以轉換上傳模型的領域爲表領域，只是他們管進入表？

好的。我找到了解決方案。如果我輸入from django.forms.models import modelform_factory，我可以用它來創建一個字段：

def get_form(self, form_class): 
    form = super(GroupCreate, self).get_form(form_class) 
    upload_form = modelform_factory(Upload,fields=('name',)) 

    for field in upload_form.base_fields: 
    form.fields[field] = upload_form.base_fields[field] 
    return form 

另外，form_valid功能必須適應：

def form_valid(self, form): 
    ... 
    upload.name = form.cleaned_data['name'] 
    ...
