python - listOfArticles() 只接受 1 个参数(给定 2 个参数)

Question

我正在尝试在模板中打印模型属性值，但收到“listOfArticles() 恰好需要 1 个参数(给定 2 个参数)”错误

views.py

def articles(request):
    model = News.objects.order_by('-date')[: 5]
    context = {
        'models': model
    }
    return render(request, 'articles.html', context)

def listOfArticles(request):
    models = News.objects.order_by('-date')[: 1]
    context = {
        'models': models
    }
    return render(request, 'articlesDetail.html', context)

urls.py

urlpatterns = patterns('',
    url(r '^$', 'articles.views.articles', name = "latest_articles"),
    url(r '^(\d+)$', 'articles.views.listOfArticles'),

)

models.py

class News(models.Model):
    title = models.CharField("Title", max_length = 256)
    author_Detail = models.CharField("Author", max_length = 128)
    date = models.DateTimeField("Published Date")


    class Meta:
        verbose_name_plural = "News"


    def __unicode__(self):
        return self.title

Answer 1

模式url(r '^(\d+)$', 'articles.views.listOfArticles'),期望 url (\d+) 中有一个整数。将您的网址模式更改为相关的内容，然后您就可以继续了。你可以做类似 r'^articles-list/$ 的事情:)
