Django Formset填充时应该是空的

我的目标是有一个formset列出5个版本的同一个表单。在提交表格时，应在DB中创建填好的表格。Django Formset填充时应该是空的

我的问题是表单重新填充数据。哪个不好。有关我可能做错什么的想法？

Models.py

from django.db import models 
from django.contrib.auth.models import User 

PRIORITIES = (
    ('1', 'High'), 
    ('2', 'Medium'), 
    ('3', 'Low'), 
) 

class Todo(models.Model): 
    task = models.CharField(max_length=200) 
    owner = models.ForeignKey(User) 
    priority = models.CharField(max_length=10, choices=PRIORITIES) 
    creation_date = models.DateField('date created', blank=True, null=True) 
    due_date = models.DateField('date due', blank=True, null=True) 
    completion_date = models.DateField('date complete', blank=True, null=True) 
    completed = models.BooleanField() 
    def __unicode__(self): 
     return self.task

Forms.py

from django import forms 
from pooflinger.todo.models import Todo 
from django.forms import ModelForm 
from django.forms.models import modelformset_factory 

TodoFormSet = modelformset_factory(Todo, max_num=2,) 

class TodoForm(forms.ModelForm): 

    class Meta: 
     model = Todo

Views.py

def todo_form(request): 
    user = request.user 
    current_date = datetime.now() 
    if request.method == 'POST': 
     formset = TodoFormSet(request.POST) 
     if formset.is_valid(): 
      formset.save() 
      return HttpResponseRedirect('/todo/') 
    else: 
     formset = TodoFormSet() 
    return render_to_response('todo/todo_formset.html', { 
     'user': user, 
     'formset': formset, 
     'current_date': current_date, 
    }, context_instance=RequestContext(request))

表格模板

<form method="post" action=""> 
    <table> 
     {{ formset }} 
    </table> 
     <button class="glue primary" type="submit" value="Submit">Submit</button></p> 

</form>

apollo13 on irc django channel找出答案。

我需要添加一个查询集

编辑

qs = Todo.objects.none() 
formset = TodoFormSet(queryset=qs)

最终代码

def todo_form(request): 
    user = request.user 
    current_date = datetime.now() 
    qs = Todo.objects.none() 
    if request.method == 'POST': 
     formset = TodoFormSet(request.POST) 
     if formset.is_valid(): 
      formset.save() 
      return HttpResponseRedirect('/todo/') 
    else: 
     formset = TodoFormSet(queryset=qs) 
    return render_to_response('todo/todo_formset.html', { 
     'user': user, 
     'formset': formset, 
     'current_date': current_date, 
    }, context_instance=RequestContext(request))
