Django int()参数必须是字符串或数字

我有一个显示表单并保存相同表单的视图。首次显示视图时,我没有错误。但是,在保存(POST)到视图时,我收到以下错误:

/ test6 / settings /的TypeError int()参数必须是字符串或数字,而不是'QueryDict'

查看

@login_required
def keyword_settings(request, keyword):
    keyword = Keyword.objects.get(keyword=keyword, status="Active")

    # If we had a POST then get the request post values.
    if request.method == 'POST':
    # Populate the form with the instance.
        form = KeywordFrom(request.POST, instance=keyword)
        # Check we have valid data before saving trying to save.
        if form.is_valid():
            form.save()

    form = KeywordFrom(instance=keyword, user=request.user)
    context = {'form': form}
    return render_to_response('sms/keyword_settings.html', context, context_instance=RequestContext(request))

表格

class KeywordFrom(forms.ModelForm):

    def __init__(self, user=None, *args, **kwargs):
        """
        Init method.
        """
        super(KeywordFrom, self).__init__(*args, **kwargs)
        if user is not None:
            this_originator_name = Originator.objects.for_user(user)
            self.fields['sender_name'] = forms.ModelChoiceField(queryset=this_originator_name)

    class Meta:
        model = Keyword

我知道问题出在sender_name上,但我尝试了不同的事情而没有解决方法。

答案 0 :(得分:7)

看看你如何覆盖表单的__init__方法:

def __init__(self, user=None, *args, **kwargs):

因此第一个显式参数(在隐式self之后)是user

现在看一下如何在POST块中实例化表单:

form = KeywordFrom(request.POST, instance=keyword)

因此,您传递的第一个参数是POST。但是表格在该位置期待user,并且会将您传递的任何内容放入该变量中。

您需要在POST实例化时传递用户,这将解决问题。但这表明为什么要乱用一个类的默认签名是个坏主意。您应该保留签名并从user

中取出kwargs
def __init__(self, *args, **kwargs):
    user = kwargs.pop('user', None)
    super(KeywordFrom, self).__init__(*args, **kwargs)
    ...etc...
