Django'QuerySet'对象没有属性'split'

Question

我希望你能看到我在这里想要做的事情,只是我想迭代发布的组的值,看起来像group = 1,3,5等,并将它们添加到数据库中.group是一个复选框.所以我想使用split选项.我得到以下信息......

'QuerySet'对象没有属性'split'

所以我的理解是在我用于填充表单的init中,这是一个查询,我需要这个但是在帖子上它应该只是一个列表.我做错了什么？

view.py

form = BatchForm(request.user, request.POST)
        # Check we have valid data before saving trying to save.
        if form.is_valid():
            # Clean all data and add to var data.
            data = form.cleaned_data
            groups = data['group'].split(",")
            for item in form.cleaned_data['group']:
                batch = Batch(content=data['content'],
                              group=Group.objects.get(pk=item),
                              user=request.user
                              )
                batch.save()

forms.py

class BatchForm(forms.ModelForm):


    class Meta:
        model = Batch
        exclude = ('user', 'group')



    def __init__(self, user=None, *args, **kwargs):
        super(BatchForm, self).__init__(*args,**kwargs)
        if user is not None:
            form_choices = Group.objects.for_user(user)
        else:
            form_choices = Group.objects.all()
        self.fields['group'] = forms.ModelMultipleChoiceField(
            queryset=form_choices
        )

template.py

{% for value, text in form.group.field.choices %}


    <input type="checkbox" name="group" value="{{ value }}" /> {{text}}<br />

{% endfor %}

因为您正在使用已清理的数据并且它是一个ModelMultipleChoice字段,所以它实际上是一个queryset.

尝试这样的事情:

form = BatchForm(request.user, request.POST)
    # Check we have valid data before saving trying to save.
    if form.is_valid():
        # Clean all data and add to var data.
        data = form.cleaned_data
        for group in data['group']:
            batch = Batch(
                content=data['content'],
                group=group,
                user=request.user
            )
            batch.save()
