Question

这是我的models.py：

select count(address_column like '%mumbai%' or null)*100/count(*) as percentage from your_table;

和forms.py:

class Segment(models.Model):
    email_segment_name = models.CharField(max_length=200)
    email_segment_status = models.BooleanField()
    user = models.ForeignKey(User,on_delete=models.SET_NULL,blank=True,null=True)
    created_at = models.DateTimeField(auto_now_add=True)  
    updated_at = models.DateTimeField(auto_now=True) 
    def __str__(self):
        return self.email_segment_name

和观点：

class SegmentForm(forms.ModelForm):
    class Meta:
        model = Segment
        fields = ['email_segment_name']
        labels = {
            'email_server_name':('Server Name'),
        }

segment_update_form.html：

@method_decorator(login_required, name='dispatch')
class SegmentUpdate(UpdateView):
    model = Segment
    form_class = SegmentForm
    template_name_suffix = '_update_form'   
    success_url = '/emails/segment'

FormView和DeleteView工作正常，但是当我更新表单时，它会响应200 OK并且页面是空白的，有什么想法吗？

Answer 1

变化：

method='post'

为：

method='get'

在segment_update_form.html

中

django updateview返回空白模板
