Question

我收到错误 - 找不到关键字参数'{u'slug'：None}'的'add_comment'。尝试了1种模式：[u'blog /（？P \ d +）/ comment / $']

我添加了 - app_name ='blog' - 用于解决命名空间

的早期错误的网址

但现在我遇到了新的错误

my urls.py

url(r'^(?P<pk>\d+)/comment/$', views.add_comment, name='add_comment')

my views.py

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('blog:post', slug=post.slug)
else:
    form = CommentForm()

template = 'blog/add_comment.html'
context = {'form': form}
return render(request, template, context)

my models.py

class Post(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
date = models.DateTimeField()
slug = models.SlugField(max_length=250, blank=True, null=True)

def __unicode__(self):
    return self.title

def save(self, *args, **kwargs):
    self.slug = slugify(self.title)
    super(Post, self).save(*args, **kwargs)

def get_absoulte_url(self):
       return reverse('blog:post.html', args=[self.slug])

class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments', blank=True, 
null=True)
user = models.CharField(max_length=250)
email = models.EmailField()
body = models.TextField()
created = models.DateTimeField(auto_now_add=True)
approved = models.BooleanField(default=False)

def approved(self):
    self.approved = True
    self.save()

def __str__(self):
    return self.user

我的模板add_comment.html

{% extends "personal/header.html" %}

{% block content %}
<h1>Add new comment</h1>
<form method='POST'>{% csrf_token %}
{{ from.as_p }}
<button type='submit'>Submit</button>
</form>
{% endblock %}

Answer 1

这是来自您提供add comment链接的页面，很可能在详细的博客/帖子页面中。

您正在创建add comment网址，而不会将pk参数传递给它。

它应该是类似的东西。

<a href="{% url 'add_comment' blog.pk %}">Add Comment</a>

但您在创建网址时遗漏了blog.pk或类似post.pk的内容。只需这样做，错误就会得到解决。

使用关键字参数'{u'slug'：None}'反向找回'add_comment'。尝试了1种模式：[u'blog /（？P <pk> \\ d +）/ comment / $']
