Question

我还在学习django。试图在我的blogdetail视图中创建评论表单。.我正在关注youtube上的教程。

 https://www.youtube.com/watch?v=An4hW4TjKhE&t=40s

本教程具有从django用户那里获取用户的表格..但是在我的表格中，我希望用户输入他的姓名，电子邮件和内容。按照本教程，我制作了表单模型，但是我不知道该如何从自己的html表单中获取数据。

我已经达到了一个阶段，在该阶段中，我可以在admin中添加注释并将其显示在我的html文件中，但是现在我遇到了错误。

             name 'post' is not defined

我的文件是..

forms.py

         from django import forms

         from.models import Comment

          class CommentForm(forms.ModelForm):
                class Meta:
                   model = Comment
                   fields = ('content', 'email', 'name' ,)

models.py

class BlogPost(models.Model):
title = models.CharField(max_length=500)
writer = models.CharField(max_length=150,default='my dept')
category =models.CharField(max_length=150)
image = models.ImageField(upload_to='images')
post   = models.TextField(max_length=2000)
Date  = models.DateField( default=datetime.date.today)


def __str__(self):
    return self.title

class Comment(models.Model):
post = models.ForeignKey(BlogPost , on_delete=models.CASCADE)
name = models.CharField (max_length = 150)
email = models.CharField (max_length = 150)
content = models.TextField ()

def __str__(self):
    return self.email

views.py

def detailview(request, id=None):
blg =  get_object_or_404(BlogPost, id=id)
comments = Comment.objects.filter( post=blg).order_by('-id')

if request.method == 'POST':
    comment_form = CommentForm(request.POST or None )
    if comment_form.is_valid():
        content = request.POST.get('content')
        Comment.objects.create(post= post ,  content=content)
        comment_form.save()
else:
   comment_form = CommentForm()

context = {'blg': blg,
           'comments': comments,
           'comment_form' : comment_form,

           }

return render(request, 'blog/blogdetail.html', context)

                        </div>
                    </div><!-- #respond end -->

实际上看起来像这样

Answer 1

    func rotateLeft(array:[Int],numberOfRotation:Int) -> [Int]
    {
     let offset = numberOfRotation % array.count
     let tempResult = array[offset...] + array[..<offset]
     return Array(tempResult)
    }

Answer 2

由于您是从html手动传递数据，因此请重写此功能

 if comment_form.is_valid():
        content = request.POST.get('content', '')
        email = request.POST.get('email', '')
        name = request.POST.get('author', '')
        comment =Comment.objects.create(post= blg, email=email, name=name,  content=content)
        return redirect('posts-detail', pk=comment.id )<this can be how you like it>

您所缺少的是在html中获取丢失的字段，这些字段取自输入中的名称属性
