问题描述

有人能帮我解决以下错误,并解释问题吗?所有我想要做的是填充一个查询集的组,但是在提交表单时,我收到以下错误...



* TypeError at / sms / addbatch
int()参数必须是字符串或数字,而不是QueryDict
*



views.py

  def add_batch(request):
#如果我们有POST然后获取请求的帖子值。
如果request.method =='POST':
form = BatchForm(request.POST)
#检查我们有有效的数据,然后保存尝试保存。
如果form.is_valid():
#清除所有数据并添加到var数据。
data = form.cleaned_data
groups = data ['group']。split(,)
用于组中的项目:
batch = Batch(content = data [消息'],
group = Group.objects.get(pk = item),
user = request.user

form.py

  class BatchForm (forms.ModelForm):


class Meta:
model = Batch


def __init __(self,user = None,* args,** kwargs):
super(BatchForm,self).__ init __(* args,** kwargs)
如果用户不是None:
form_choices = Batch.objects.for_user_pending(user )
其他:
form_choices = Batch.objects.all()

self.fields ['group'] = forms.ModelMultipleChoiceField(
queryset = form_choices

models.py

  class BatchManager(models.Manager):
def for_user_pending(self,user):
return self.get_query_set()。filter(user = user,status =Pending)


解决方案

您正在将 request.POST 作为用户参数到您的表单。这样做:

  form = BatchForm(data = request.POST)

 

 #第一个参数--- v 
def __init __(self,user = None,...

#first parameter --- v
form = BatchForm(request.POST)


Can someone help me out with the following error below and explain the issue? All I'm trying to do it populate a group with a query set, but upon submitting the form I get the following error...

*TypeError at /sms/addbatchint() argument must be a string or a number, not 'QueryDict'*

views.py

def add_batch(request):
    # If we had a POST then get the request post values.
    if request.method == 'POST':
        form = BatchForm(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 groups:
                batch = Batch(content=data['message'],
                              group=Group.objects.get(pk=item),
                              user=request.user
                              )

form.py

class BatchForm(forms.ModelForm):


    class Meta:
        model = Batch


    def __init__(self, user=None, *args, **kwargs):
        super(BatchForm, self).__init__(*args,**kwargs)
        if user is not None:
            form_choices = Batch.objects.for_user_pending(user)
        else:
            form_choices = Batch.objects.all()

        self.fields['group'] = forms.ModelMultipleChoiceField(
            queryset=form_choices
        )

models.py

class BatchManager(models.Manager):
    def for_user_pending(self, user):
        return self.get_query_set().filter(user=user, status="Pending")
解决方案

You are passing request.POST as the user parameter to your form. Do this:

form = BatchForm(data=request.POST)
#  first parameter ---v
def __init__(self, user=None, ...

#  first parameter ---v
form = BatchForm(request.POST)
