诀窍是使用"ModelFormset"而不是仅使用表单集，因为它们允许使用查询集进行初始化.这些文档是此处，您可以做什么在创建模型表单集时提供一个form = *，在实例化表单集时提供queryset = *.form = *争论没有得到充分的记录(必须在代码中进行一些挖掘以确保它确实存在).

The trick is to use a "ModelFormset" instead of just a formset since they allow initialization with a queryset. The docs are here, what you do is provide a form=* when creating the model formset and queryset=* when your instantiating the formset. The form=* arguement is not well documented (had to dig around in the code a little to make sure it is actually there).

def edit(request):
    PointFormSet = modelformset_factory(Point, form = PointForm)
    qset = Point.objects.all() #or however your getting your Points to modify
    formset = PointFormset(queryset = qset)
    if request.method == 'POST':
        #deal with posting the data
        formset = PointFormset(request.POST)
        if formset.is_valid():
            #if it is not valid then the "errors" will fall through and be returned
            formset.save()
        return #to your redirect

    context_dict = {'formset':formset,
                    #other context info
                    }

    return render_to_response('your_template.html', context_dict)

因此，代码很容易遍历.如果请求是GET，则将实例化的表单返回给用户.如果请求是POST，并且表单是 not .is_valid()，则错误掉线"并在同一模板中返回.如果请求是POST且数据有效，那么将保存表单集.

So the code walks through easily. If the request is a GET then the instantiated form is returned to the user. If the request is a POST and the form is not .is_valid() then the errors "fall through" and are returned in the same template. If the request is a POST and the data is valid then the formset is saved.

希望有帮助.
