问题描述
我有一个博客应用程序，我正在尝试在该应用程序上添加评论功能，但显示不正确，该评论表单假定显示名称，电子邮件和正文，但未显示... 这是我的网络应用程序中的图片
下面是我的view.py代码
from django.contrib import messages
from django.contrib.auth.mixins import (LoginRequiredMixin,UserPassesTestMixin)
from django.contrib.auth.models import User
from django.urls import reverse_lazy,reverse
from django.http import HttpResponseRedirect,Http404
from django.shortcuts import render,get_object_or_404,redirect
from django.views.generic import (ListView,DetailView,CreateView,UpdateView,DeleteView)
from .models import Post
from django.core.files.storage import FileSystemStorage
from .forms import PostForm,CommentForm
from . import models
def home(request):
context = {
'posts': Post.objects.all()
}
return render(request,'blog/home.html',context)
def upload(request):
if request.method == 'POST':
form = PostForm(request.POST,request.FILES)
if form.is_valid():
form.save()
return redirect('post_detail')
else:
form = PostForm()
return render(request,'blog/post_detail.html',{'form': form })
class PostListView(ListView):
model = Post
template_name = 'blog/home.html'
context_object_name = 'posts'
ordering = ['-date_posted']
paginate_by = 6
class UserPostListView(ListView):
model = Post
template_name = 'blog/user_posts.html'
context_object_name = 'posts'
paginate_by = 6
def get_queryset(self):
user = get_object_or_404(User,username=self.kwargs.get('username'))
return Post.objects.filter(author=user).order_by('-date_posted')
class PostDetailView(DetailView):
model = Post
def post_detail(request,slug):
template_name = 'post_detail.html'
post = get_object_or_404(Post,slug=slug)
comments = post.comments.filter(active=True)
new_comment = None
# Comment posted
if request.method == 'POST':
comment_form = CommentForm(data=request.POST)
if comment_form.is_valid():
# Create Comment object but don't save to database yet
new_comment = comment_form.save(commit=False)
# Assign the current post to the comment
new_comment.post = post
# Save the comment to the database
new_comment.save()
else:
comment_form = CommentForm()
return render(request,template_name,{'post': post,'comments': comments,'new_comment': new_comment,'comment_form': comment_form})
下面的models.py代码
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
from groups.models import Group
from PIL import Image
import misaka
class Post(models.Model):
title = models.CharField(max_length=100)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User,on_delete=models.CASCADE)
message = models.TextField()
message_html = models.TextField(editable=False)
group = models.ForeignKey(Group,related_name="posts",null=True,blank=True,on_delete=models.CASCADE)
image = models.ImageField(upload_to='media/',default='/media/default-user.jpg')
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post-detail',kwargs={'pk': self.pk})
def save(self,*args,**kwargs):
self.message_html = misaka.html(self.message)
super().save(*args,**kwargs)
img = Image.open(self.image.path)
if img.height > 300 or img.width > 300:
output_size = (500,500)
img.thumbnail(output_size)
img.save(self.image.path)
class Comment(models.Model):
post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments')
name = models.CharField(max_length=80)
email = models.EmailField()
body = models.TextField()
created_on = models.DateTimeField(auto_now_add=True)
active = models.BooleanField(default=False)
class Meta:
ordering = ['created_on']
def __str__(self):
return 'Comment {} by {}'.format(self.body,self.name)
Forms.py代码也
from django import forms
from . import models
from .models import Post,Comment
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = ("title","group","image")
def __init__(self,**kwargs):
user = kwargs.pop("user",None)
super().__init__(*args,**kwargs)
if user is not None:
self.fields["group"].queryset = (
models.Group.objects.filter(
pk__in=user.groups.values_list("group__pk")
)
)
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
fields = ('name','email','body')
最后是post_detail.html
{% extends "blog/base.html" %}
{% block content %}
<article class="media content-section">
<img class="rounded-circle article-img" src="{{ object.author.profile.image.url }}">
<div class="media-body">
<div class="article-metadata">
<a class="mr-2" href="{% url 'posts:user-posts' object.author.username %}">{{ object.author }}</a>
<small class="text-muted">{{ object.date_posted|date:"F d,Y" }}</small>
{% if object.author == user %}
<div>
<a class="btn btn-secondary btn-sm mt-1 mb-1" href="{% url 'posts:post-update' object.id %}">Update</a>
<a class="btn btn-danger btn-sm mt-1 mb-1" href="{% url 'posts:post-delete' object.id %}">Delete</a>
</div>
{% endif %}
</div>
<h2 class="article-title">{{ object.title }}</h2>
{% if object.image %}
<img src="{{ object.image.url }}" class="card-img-top" />
{% endif %}
<p class="article-content">{{ object.content }}</p>
</div>
</article>
<div class="container">
<div class="row">
<div class="col-md-8 card mb-4 mt-3 left top">
<div class="card-body">

<p class=" text-muted">{{ post.author }} | {{ post.created_on }}</p>
<p class="card-text ">{{ post.content | safe }}</p>
</div>
</div>
<div class="col-md-8 card mb-4 mt-3 ">
<div class="card-body">
<!-- comments -->
<h2>{{ comments.count }} comments</h2>
{% for comment in comments %}

{{ comment.body | linebreaks }}
</div>
{% endfor %}
</div>
</div>
<div class="col-md-8 card mb-4 mt-3 ">
<div class="card-body">
{% if new_comment %}
<div class="alert alert-success" role="alert">

</div>
{% else %}
<h3>Leave a comment</h3>
<form method="post" style="margin-top: 1.3em;">
{{ comment_form.as_p }}
{% csrf_token %}
<button type="submit" class="btn btn-primary btn-lg">Submit</button>
</form>
{% endif %}
</div>
</div>
</div>
</div>
{% endblock %}
这是post_detail.html代码
{% extends "blog/base.html" %}
{% block content %}
<article class="media content-section">

{% endif %}
</div>
<h2 class="article-title">{{ object.title }}</h2>
{% if object.image %}
<img src="{{ object.image.url }}" class="card-img-top" />
{% endif %}
<p class="article-content">{{ object.content }}</p>

</article>
<div class="container">
<div class="row">
<div class="col-md-8 card mb-4 mt-3 left top">
<div class="card-body">

<p class=" text-muted">{{ post.author }} | {{ post.created_on }}</p>
<p class="card-text ">{{ post.content | safe }}</p>

</div>
<div class="col-md-8 card mb-4 mt-3 ">
<div class="card-body">
<!-- comments -->
