如何在 Django 中保存来自 post 请求的数据？

Question

我正在尝试使用 POST 方法在博客中实现评论。我想保存通过 POST 方法获取数据的名称、电子邮件、文本并将其保存到数据库中。此外，日期字段应获取 date.now() 并且博客字段应获取博客或博客的 ID。代码看起来像这样 -

models.py :


from django.db import models

class Blog......


class Comment(models.Model):
    id = models.AutoField(primary_key=True, default=0)
    blog = models.ForiegnKey(Blog_tables, on_delete=models.CASCADE)
    name = models.CharField(max_length=200)
    email = models.EmailField()
    Text = models.TextField()
    date = models.DateField()

    def __str__(self):
        return self.Text

views.py

from .models import Blog, Comment
from django.shortcuts import render, get_object_or_404, redirect
from django.template import loader, RequestContext
from django.http import HttpResponse, HttpResponseRedirect



def blog_detail(request, blog_id):
    blog = get_object_or_404(Blog, pk=blog_id)
    return render(request, 'home/detail.html', {'blog': blog})

def post_comment(request, blog_id):
    # Here's a post code to be implemented. Please read the commented text

    # 'blog' field of models will get the id of the blog
    # 'name' field will get the POST method value of input name="name"
    # 'email' field will get the POST method value of input name="email"
    # 'text' field will get the POST method value of input name="text"
    # 'date' will get the current Date 
    # All the above data will be saved in the database

html 模板：blog_detail.html

<html>
  <body>
<!--...Blog Text Here...-->

<!-- Comment Section -->

        <form action="/blogs/{{blog_id}}/comment" method ="post">
            {% csrf_token %}
            <input type="text" name="name" id="name" placeholder="Enter Your Name"/>
            <input type="text" name="email" id="email" placeholder="Enter Your Email"/>
            <input type="text" name="comments" id="comments" placeholder="Comments here"/>


            <input type="submit" value="Post"/>
        </form>
  </body>
</html>

请帮我解决问题。

表格布局如下：

请帮我从布局中的评论部分获取值并保存到数据库中

我也试过这个 views.py :

def post_comment(request, blog_id):
    if request.method == 'POST':
        data = request.POST.get("name", "email", "comment")
       # blog = get_object_or_404(Blog_tables, pk=blog_id)
        p = Blog_Comment_table(blog= data.name, comment_name=data.email, 
comment_email= data.email, comment_Text= data.comment, comment_data = 
timezone.now())
        p.save()
        return HttpResponseRedirect('/thanks/')
    else:
        return render(request, '/blogs/' + blog_id + '/comment', {'error_message': 'Error'})

应该是这样的：

from django.utils import import timezone
from .forms import CommentForm

def post_comment(request, blog_id):
   if request.method == 'POST':
       form = CommentForm(request.POST)
       if form.is_valid():
           data = form.cleaned_data
           blog = get_object_or_404(Blog, id=blog_id)
           Comment.objects.create(
               blog = blog,
               name = data.name
               email = data.email
               text = data.text
               date = timezone.now()
           )
