篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了NoReverseMatch at / posts / post / 18 / comment / Django Error相关的知识，希望对你有一定的参考价值。
我一直在收到这个错误，我似乎无法修复它。以下是它的截图：erros image
在这里我的观点是.py：'
from django.shortcuts import render, get_object_or_404, redirect
from django.contrib import messages
from django.contrib.auth.mixins import LoginRequiredMixin
from posts.forms import PostForm, CommentForm
from django.core.urlresolvers import reverse_lazy
from django.http import Http404
from django.views import generic
from braces.views import SelectRelatedMixin
from . import forms
from . import models
from django.contrib.auth import get_user_model
User = get_user_model()
class PostList(SelectRelatedMixin, generic.ListView):
model = models.Post
select_related = ("user", "group")
class UserPosts(generic.ListView):
model = models.Post
template_name = "posts/user_post_list.html"
def get_queryset(self):
try:
self.post_user = User.objects.prefetch_related("posts").get(
username__iexact=self.kwargs.get("username")
)
except User.DoesNotExist:
raise Http404
else:
return self.post_user.posts.all()
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context["post_user"] = self.post_user
return context
class PostDetail(SelectRelatedMixin, generic.DetailView):
model = models.Post
select_related = ("user", "group")
def get_queryset(self):
queryset = super().get_queryset()
return queryset.filter(
user__username__iexact=self.kwargs.get("username")
)
class CreatePost(LoginRequiredMixin, SelectRelatedMixin, generic.CreateView):
# form_class = forms.PostForm
fields = ('message','group')
model = models.Post
# def get_form_kwargs(self):
# kwargs = super().get_form_kwargs()
# kwargs.update({"user": self.request.user})
# return kwargs
def form_valid(self, form):
self.object = form.save(commit=False)
self.object.user = self.request.user
self.object.save()
return super().form_valid(form)
class DeletePost(LoginRequiredMixin, SelectRelatedMixin, generic.DeleteView):
model = models.Post
select_related = ("user", "group")
success_url = reverse_lazy("posts:all")
def get_queryset(self):
queryset = super().get_queryset()
return queryset.filter(user_id=self.request.user.id)
def delete(self, *args, **kwargs):
messages.success(self.request, "Post Deleted")
return super().delete(*args, **kwargs)
def add_comment_to_post(request, pk):
post = get_object_or_404(models.Post, pk=pk)
if request.method == "POST":
form = CommentForm(request.POST)
if form.is_valid():
comment = form.save(commit=False)
comment.post = post
comment.save()
return redirect('posts:single', pk=post.pk)
else:
form = CommentForm()
return render(request, 'posts/comment_form.html', {'form': form})
def comment_approve(request, pk):
comment = get_object_or_404(Comment, pk=pk)
comment.approve()
return redirect('posts:single', pk=comment.post.pk)
def comment_remove(request, pk):
comment = get_object_or_404(Comment, pk=pk)
post_pk = comment.post.pk
comment.delete()
return redirect('posts:single', pk=post_pk.pk)
这是我的models.py：
from django.conf import settings
from django.core.urlresolvers import reverse
from django.db import models
from django.utils import timezone
import misaka
from groups.models import Group
from django.contrib.auth import get_user_model

message_html = models.TextField(editable=False)
group = models.ForeignKey(Group, related_name="posts",null=True, blank=True)
def __str__(self):
return self.message
def save(self, *args, **kwargs):
self.message_html = misaka.html(self.message)
super().save(*args, **kwargs)
def approve_comments(self):
return self.comments.filter(approved_comment=True)
def get_absolute_url(self):
return reverse(
"posts:single",
kwargs={
"username": self.user.username,
"pk": self.pk
}
)
class Meta:
ordering = ["-created_at"]
unique_together = ["user", "message"]
class Comment(models.Model):
post = models.ForeignKey('posts.Post', related_name='comments')
author = models.CharField(max_length=200)
text = models.TextField()
created_date = models.DateTimeField(default=timezone.now)
approved_comment = models.BooleanField(default=False)
def approve(self):
self.approved_comment = True
self.save()
def get_absolute_url(self):
return reverse("post_list")
def __str__(self):
return self.text
这是我的post_detail.html：

我似乎无法在django中找到此高级错误的修复程序。任何人都可以帮忙。
我一直试图解决它，但不能，每个评论都被认为是与评论的链接。
谢谢
答案
错误指向
return redirect('posts:single', pk=post.pk)
这可能导致错误，因为除了username之外，它还希望你传递一个pk参数。
以上是关于NoReverseMatch at / posts / post / 18 / comment / Django Error的主要内容，如果未能解决你的问题，请参考以下文章
NoReverseMatch at ...... in django
Django NoReverseMatch at / 路径名和/或顺序是不是冲突？
NoReverseMatch at /accounts/password-reset/ 用于 Django 中的密码重置
NoReverseMatch at / Reverse for 'singlepropa' 与参数 '('mens-shirt-1',)' 未找到。已尝试 1 种模式
