            messages.error(request, 'Please enter all required fields')                     
    else:                    
        form2 = CraveReplyForm()
        form1=CraveDataForm()  


    return render(request, "crave/crave.html", { 'form1' : form1, 'form2' : form2 })

models.py

class crave_data(models.Model):
    person = models.ForeignKey(User)
    post=models.TextField(blank = True,null = True)
    date= models.DateTimeField(auto_now_add=True, blank=True)
    def __unicode__(self):
        return self.post



class comments(models.Model):

    crave=models.ForeignKey(crave_data)
    reply=models.CharField(max_length=1000, blank = True,null = True)
    date= models.DateTimeField(auto_now_add=True, blank=True)
    def __unicode__(self):
        return self.reply

forms.py

class CraveDataForm(forms.ModelForm):
    class Meta:
        model = crave_data
        exclude=['date', 'password1', 'password2', 'username', 'person']

class CraveReplyForm(forms.ModelForm):
    class Meta:
        model = comments
        exclude=['date', 'crave', 'password1', 'password2', 'username']

我的form1正在验证并在后端保存但是form2没有保存在后端。错误在“reply.person = request.user”行中，错误是“crave_comments.crave_id可能不为NULL” 请帮助我，我想保存评论，即回复那个perticuler crave_made即发布

Answer 1

保存表单时，您是否尝试过使用commit = True？您收到的错误告诉您，在添加外键关系之前需要保存回复。

Answer 2

在保存和创建reply时，您还需要指定crave属性。

将您的代码更新为

        reply = form2.save(commit=False)
        reply.person=request.user
        reply.crave = crave_made
        reply.save()

假设您要使用之前创建的crave_made进行保存。

第二种形式没有得到验证django
