Question

完整错误：

未找到带有参数'（38，）'的'post-detail'。

尝试了1个模式：

['（？P [^ /] +）/ posts /（？P [0-9] +）/ $']

models.py

    class Post(models.Model):
        article_title = models.CharField(max_length=100)
        content = models.TextField()
        date_published = models.DateTimeField(db_index=True, default=timezone.now)
        game = models.ForeignKey('library.Game', on_delete=models.CASCADE)
        article_image = models.ImageField(default='/media/default.png', upload_to='article_pics')
        platform = models.CharField(default='PC', max_length=20)

        def __str__(self):
            return self.article_title

        class Meta:
            ordering = ["-date_published"]


        def get_absolute_url(self):
            return reverse('post-detail', kwargs={'pk': self.pk})

class Game(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    cover = models.ImageField()
    cover_display = models.ImageField(default='default.png')
    developer = models.CharField(max_length=100)
    twitter = models.CharField(max_length=50, default='')

    def __str__(self):
        return self.title

views.py

class TitlePostListView(ListView):
    model = Post
    template_name = 'main/title_posts.html'
    context_object_name = 'posts'
    paginate_by = 5


    def get_queryset(self):
        title = get_object_or_404(Game, title=self.kwargs.get('title'))
        return Post.objects.filter(game=title).order_by('-date_published')

    def get_context_data(self, **kwargs):
        context = super(TitlePostListView, self).get_context_data(**kwargs)
        context['game'] = get_object_or_404(Game, title=self.kwargs.get('title'))
        return context

class PostDetailView(DetailView):
    model = Post

urls.py

 path('<str:title>/posts', TitlePostListView.as_view(), name='title-posts'),
 path('<str:title>/posts/<int:pk>/', PostDetailView.as_view(), name='post-detail'),

我正在尝试使路径类似于domain.com/Minecraft/posts/38，但出现错误，可能是因为未定义str：title。我不确定如何将其添加到我的PostDetailView中。

编辑：

post-detail.html

{% extends "main/base.html" %}
{% load static %}
{% block styles %}
    <link rel="stylesheet" type="text/css" href="{% static 'main/css/post_detail.css' %}">
{% endblock styles %}
{% block content %}
    <div class="container black container-position">
        <div class="row">
            <article class="media content-section">
                <div class="media-body">
                    <h2 class="article-title">{{ object.article_title }}</h2>
                 <div class="article-content">{{ object.content|safe }}</div>
                </div>
            </article>
        </div>
    </div>
{% endblock content %}

Answer 1

在此行：

return reverse('post-detail', kwargs={'pk': self.pk})

您缺少其他必需的参数title，它应该类似于：

return reverse('post-detail', kwargs={'pk': self.pk, 'title': 'sometitle'})

看看错误中显示的模式：

['（？P [^ /] +） /帖子/（？P [0-9] +）/ $']

在第一部分中，您可以看到(?P[^/]+)的加号（+）表示“至少一个字符”，因此标题不允许为空，并且您还没有为该情况定义URL模式，因此是错误。

找不到带有参数'（38，）'的'post-detail'
