Django 应用程序在本地运行，在部署到 DigitalOcean 时中断

Question

这是我设置的 DigitalOcean droplet 上的错误：

Django 错误（第 38 行已突出显示）

Reverse for 'vendor' with arguments '()' and keyword arguments '{u'vendor': u''}' not found. 1 pattern(s) tried: [u'deals/vendor/(?P<vendor>[\w-]+)$']
...
34                {% if vendors %}
35                  <li class="divider"></li>
36                  <li class="dropdown-header">By Vendor</li>
37                  {% for vendor_item in vendors|slice:"0:3" %}
38                    <li><a href={% url 'deals:vendor' vendor=vendor_item.slug %}>{{ vendor_item.name }}</a></li>
39                  {% endfor %}
40                {% endif %}

错误不是本地发生的。我看到关键字是一个空字符串，所以我去shell调查。

>>> from deals.models import Vendor
>>> vendor_qs = Vendor.objects.all()
>>> for item in vendor_qs: print item.slug
...
my-first-vendor
my-second-vendor
>>>

这是我要访问的页面的模型、视图和 url：

models.py

...
class Vendor(models.Model):
    name = models.CharField(max_length=200)
    slug = models.CharField(max_length=200, blank=True)
    url = models.CharField(max_length=200, blank=True)
    location = models.CharField(max_length=200, blank=True, null=True)
    shipping = models.BooleanField(blank=True)
    img = models.ImageField(blank=True)

    def __str__(self):
        return self.name

views.py

...
def index(request, data=None): 
if data is None:
    data = {}

vendors = Vendor.objects.annotate(Count('deal')) \
    .order_by('name')
data['vendors'] = vendors

categories = Category.objects.annotate(Count('deal')) \
    .exclude(deal__count__lt = 40) \
    .order_by('name')
data['categories'] = categories

return render(request, 'deals/_index.html', data)

urls.py

urlpatterns = patterns('',
    # Examples:
    url(r'^$', views.index, name='index' ),
    url(r'vendor/(?P<vendor>[\w-]+)$', views.get_deals_by_vendor, name='vendor'),
    url(r'test_type/$', views.view_model_subclass_by_deal), # Remove in production
    url(r'todays_deals/$', views.view_deals_updated_today), # Remove in production
    )

同样，此代码的 100% 完全可以在本地找到。我花了大约 10 个小时进行故障排除，但我无法弄清楚...

注意：test_type 视图工作正常（只是一个输出其他模型子类的测试视图），而 todays_deals 不起作用。它returns:

render_to_string() got an unexpected keyword argument 'context'

它的视图如下所示： def view_deals_updated_today（请求）：今天 = date.today()

    todays_deals = Deal.objects \
        .filter(updated_at__gte = today) \
        .exclude(created_at__lte = today) \
        .select_subclasses()

    return render_to_response('test/deal_list.html', context = {'todays_deals':todays_deals})

我很困惑。即使 'pip freeze' 在这些环境之间也是相同的...

更新：

问题是 nginx 配置中的单个正斜杠。

配置的静态部分应该是“/static”而不是“/static/”
