如何在URL中使用通用视图中的slug？(How to use slug in URL with generic view?)

我如何通过它的标题来查看单篇文章，如下所示： news/article_name ？

我设法使用数字（ <int:pk>在urls中，然后使用{% url 'article' article.id %}在模板中访问它），所以news/1实际上起作用。 而不是使用数字，我想使用标题，并不知道如何。

models.py

class Article(models.Model): headline = models.CharField(max_length=200) date_created = models.DateTimeField(auto_now_add=True) date_updated = models.DateTimeField(auto_now=True) author = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField() def __str__(self): return self.headline

urls.py

path('<slug:headline>/', views.DetailView.as_view(), name='article'),

views.py

class ArticleView(generic.DetailView): model = Article template_name = 'news/index.html' context_object_name = 'article' local_context = {**context, **{'show_comments':False}}

在文章模板中的某处

<p><a href="{% url 'article' %}">Read more</a></p>

How can I view a single article by it's headline like so: news/article_name?

I managed to make it work with numbers (<int:pk> in urls then access it in template using {% url 'article' article.id %}) so news/1 actually worked. Instead of using numbers I want to use headlines and can't figure out how.

models.py

class Article(models.Model): headline = models.CharField(max_length=200) date_created = models.DateTimeField(auto_now_add=True) date_updated = models.DateTimeField(auto_now=True) author = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField() def __str__(self): return self.headline

urls.py

path('<slug:headline>/', views.DetailView.as_view(), name='article'),

views.py

class ArticleView(generic.DetailView): model = Article template_name = 'news/index.html' context_object_name = 'article' local_context = {**context, **{'show_comments':False}}

somewhere in article template

<p><a href="{% url 'article' %}">Read more</a></p>

当您使用主键时，必须将其包含在URL标记中。

{% url 'article' article.id %}

同样，你必须在URL标签中加入标题。

{% url 'article' article.headline %}

请注意，包含单独的slug字段而不是使用headline可能会更好，因此您可以使用/news/man-bites-dog而不是/news/Man%20Bites%20Dog

class Article(models.Model): headline = models.CharField(max_length=200) slug = models.SlugField()

然后你会将url标签更改为：

{% url 'article' article.slug %}

When you used the primary key you had to include that in the URL tag.

{% url 'article' article.id %}

In the same way, you have to include the headline in the URL tag.

{% url 'article' article.headline %}

Note that it might be better to include a separate slug field instead of using headline, so that you get URLs like /news/man-bites-dog instead of /news/Man%20Bites%20Dog

class Article(models.Model): headline = models.CharField(max_length=200) slug = models.SlugField()

Then you would change the url tag to:

{% url 'article' article.slug %}
