Question

我创建了一个应用，可以使用django-autoslug根据帖子的slug自动生成title。

我已成功显示ListView中的每个帖子，但无法链接到DetailView。想法？

我收到以下错误：

Reverse for '/scholarships/test-scholarship-1/' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

模型

from django.db import models
from django.core.urlresolvers import reverse
from autoslug import AutoSlugField


class Scholarship(models.Model):
    title = models.CharField(max_length=255)
    slug = AutoSlugField(populate_from='title')

    def __unicode__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('single_scholarship', kwargs={'slug': self.slug})

视图

from django.views.generic import ListView, DetailView
from .models import Scholarship


class ScholarshipDirectoryView(ListView):
    model = Scholarship
    template_name = 'scholarship-directory.html'


class SingleScholarshipView(DetailView):
    model = Scholarship
    template_name = 'single-scholarship.html'

网址

from django.conf.urls import patterns, url

from .views import ScholarshipDirectoryView, SingleScholarshipView

urlpatterns = patterns('',
    url(r'^$', ScholarshipDirectoryView.as_view(), name='scholarship_directory'),
    url(r'^(?P<slug>[A-Za-z0-9_\-]+)/$', SingleScholarshipView.as_view(), name='single_scholarship'),
)

相关模板

{% for scholarship in scholarship_list %}
<p><a href="{% url scholarship.get_absolute_url %}">Read more &rarr;</a></p>

我必须错过一些明显的东西......

Answer 1

您已将实际完整网址从scholarship.get_absolute_url传递到{% url %}代码。您应该使用其中一个，而不是两个：{{ scholarship.get_absolute_url }} 或 {% url 'single_scholarship' scholarship.slug %}。

Answer 2

尝试使用

{{ scholarship.get_absolute_url }}

Answer 3

你可以尝试

<a href="{{scholarship.get_absolute_url}}">Read more &rarr;</a>
