    title = forms.CharField(required=True,min_length=1,max_length=200) 
    video_id = forms.CharField(required=True,min_length=1,max_length=20)

     title = self.cleaned_data.get('title') 
     if title.strip()=='': 
      raise forms.ValidationError('Enter a Valid Title') 
     else:

class Meta: 
    model = Videos 
     fields = ('title','video_id','category','description') 

Answer 1

所有元首先應該屬於AddVideoViaLinkForm。在這個類中，你可以添加保存功能，這將爲你做這個：

def save(self): 
    ids = self.cleaned_data['video_id'].split(",")# it depends what is your id separator 
    title = self.cleaned_data['title'] 
    for id in ids: 
     Videos.objects.create(video_id=id, title=title, ...)
