'评论'对象没有属性'is_valid'

问题描述 投票:0回答:1

我正在制作评论应用程序以对帖子发表评论。

这是我的comments/forms.py

from django import forms
from .models import Comments
class CommentForm(forms.ModelForm):
    theuser     ='hhh123'
    thepost     ='Bitcoin'
    thecontent  =forms.CharField(widget=forms.TextArea)
    class Meta:
        model=Comments
        fields = ('user','post','content')

这是我的comments/models.py

from django.db import models
from django.conf import settings
from currency.models import Currencies
class Comments(models.Model):
    user        =models.ForeignKey(settings.AUTH_USER_MODEL,default=1)
    post        =models.ForeignKey(Currencies)
    content     =models.TextField()
    timestamp   =models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.user.username

这是我的comments/views.py

from django.conf import settings
from currency.models import Currencies
from django.shortcuts import render
from django.http import HttpResponse, HttpResponseRedirect, Http404
from django.shortcuts import render, get_object_or_404, redirect
from .models import Comments
def mycommentview(request):
    instance = Comments.objects.all()
    myformofcomments=Comments(request.POST or None)
    if myformofcomments.is_valid():
        print(myformofcomments.cleaned_data)

    context = {

         "instance" : instance,
         "myformofcomments": myformofcomments,
    }
    return render(request, "home2.html",context)

当我加载页面时,我收到以下错误:

/ mycommentview /中的AttributeError

评论'对象没有属性'is_valid'

我的错误是什么?

当您打算使用Comments(这是一种形式)时,您似乎使用了CommentForm(这是一个模型)。
