嗨我在帖子上写评论有问题请帮帮我。
这是我的网址
from django.conf.urls import url
from django.views.generic import ListView, DetailView
from forum.models import Post
from . import views
from .views import createPost
urlpatterns = [
url(r'^$', ListView.as_view(queryset=Post.objects.all().order_by("-date")[:25], template_name="forum/forum.html")),
url(r'^(?P<pk>\d+)$', DetailView.as_view(model=Post, template_name='forum/post.html')),
url(r'^createPost/', createPost.as_view(), name='createPost'),
url(r'^(?P<slug>[-\w]+)/comment/$', views.add_comment, name='add_comment')
]
这是我的观点
from django.shortcuts import render, redirect
from .forms import PostForm
from django.views.generic import TemplateView
from .forms import CommentForm
from django.shortcuts import get_object_or_404
from .models import Post
class createPost(TemplateView):
template_name = 'forum/createPost.html'
def get(self, request):
form = PostForm()
return render(request, self.template_name, {'form': form})
def post(self, request):
form = PostForm(request.POST)
if(form.is_valid()):
form.save()
return redirect('/forum')
def add_comment(request, slug):
post = get_object_or_404(Post, slug=slug)
if(request.method == "Post"):
form = CommentForm(request.Post)
if(form.is_valid()):
comment = form.save(commit=False)
comment.post = post
comment.save()
return redirect('/forum/createPost', slug=post.slug)
else:
form = CommentForm()
template = 'forum/addComment.html'
context = {'form': form}
return render(request, template, context)
最后这是我的模特
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=140)
body = models.CharField(max_length=500)
date = models.DateTimeField()
def __str__(self):
return self.title
class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments', on_delete=None)
com_title = models.CharField(max_length=140)
com_body = models.CharField(max_length=500)
def __str__(self):
return self.com_title
我认为问题与我使用的模板视图有关,当我调用Post it trys将slug放入模板时。我是Django的新手,我真的很乐意帮助他们。我也有表格文件可能是相关的,所以如果你认为它请现在让我,所以我可以添加到问题。谢谢!

比Yasin Bahtiyar更详细一点。
添加到您的Post
模型
slug = models.SlugField (
verbose_name = "Slug",
allow_unicode = True,
unique=True)
这将确保slug是独一无二的,你不会得到2条记录,但是你需要确保你的slug在保存之前是唯一的。
如果您想根据标题设置slug,请执行以下操作:
slug = models.SlugField (
verbose_name = "Slug",
allow_unicode = True,
unique=True,
blank = True,
null = True)
将一个保存功能添加到模型中:
def save(self, *args, **kwargs):
if not self.slug: self.slug = slugify(self.title)
super(Post, self).save(*args, **kwargs)
同样,您需要添加代码以确保它是唯一的。
