Question

我正在开发基于Django的RSVP项目。当我想制作一个事件模型并将其与每个用户连接时。它总是有这个错误！活动只有两个字段：user和name。

views.py：

def create_event(request):
    if request.method=='POST':
        form = CreateEventForm(data=request.POST)                                                                                                                                                                         
        if form.is_valid():
        form.save()
        return redirect('http://vcm-2971.vm.duke.edu:8080/rsvp/profile')
        else:
            form= CreateEventForm()
        args= {'form':form}
            return render(request, 'rsvp/create_event.html',args)
    else:
        form= CreateEventForm()
    args= {'form':form}
        return render(request, 'rsvp/create_event.html',args)

models.py：

class Event(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE)
    name = models.CharField(max_length=100,default='')

forms.py：

class CreateEventForm(ModelForm):
    #name = forms.CharField(max_length=100,required = True)                                                                                                                                                 

    class Meta:
        model = Event
        fields=(
            'name',
        )

def create_event(request):
    if request.method=='POST':
        form = CreateEventForm(data=request.POST)                                                                                                                                                                         
        if form.is_valid():
        form = form.save(commit=False)
        form.user = request.user
        form.save()
        return redirect('http://vcm-2971.vm.duke.edu:8080/rsvp/profile')
        else:
            form= CreateEventForm()
        args= {'form':form}
            return render(request, 'rsvp/create_event.html',args)
    else:
        form= CreateEventForm()
    args= {'form':form}
        return render(request, 'rsvp/create_event.html',args)

您需要登录才能使用此表单，或者需要将自定义User instance传递到Model

的用户字段

列“user_id”中的空值违反非空约束
