python之html模板不会在python django中呈现

我知道这是一个非常菜鸟的问题，但是当我尝试呈现我的产品模板时需要帮助，它返回此错误，前两个页面已正确呈现，例如 about 、 home 和联系，但是当我尝试为我的产品 页面添加另一个应用时，它无法加载。

#THE ERROR 
Page not found (404) 
Request Method: GET 
Request URL:    http://localhost:8000/%7B%25%20url%20'products'%7D 
Using the URLconf defined in trydjango.urls, Django tried these URL  
patterns, in this order: 
1. ^admin/ 
2. ^$ [name='home'] 
3. ^about/$ [name='about'] 
4. ^products/$ [name='products'] 
5. ^contact/$ [name='contact'] 
6. ^accounts/ 
7.^static\/(?P<path>.*)$ 
8.^static\/(?P<path>.*)$ 
 
The current URL, {% url 'products'}, did not match any of these. 
 
#This is the structure 
src 
>> contact 
>> products 
   >> migrations 
   >> templates 
      >> products.html  
>> profiles 
>> migrations 
>> templates 
   >> about.html 
   >> base.html 
   >> home.html 
   >> navbar.html 
 
#from the products app this is the views.py 
 
def products(request): 
   context = {} 
   template = 'products.html' 
   return render(request, template,context) 
 
#This is the config for urls 
 
 
from profiles import views as profiles_views 
from contact import views as contact_views 
from products import views as products_views 
 
urlpatterns = [ 
url(r'^admin/', admin.site.urls), 
url(r'^$', profiles_views.home, name='home'), 
url(r'^about/$', profiles_views.about, name='about'), 
url(r'^products/$', products_views.products, name='products'), 
url(r'^contact/$', contact_views.contact, name='contact'), 
url(r'^accounts/', include('allauth.urls')), 
 
] 
 
#and this is where I called it in navbar 
<li class="nav-item"> 
      <a class="nav-link js-scroll-trigger" href="{%url'products'}">Products</a> 
</li> 

请您参考如下方法:

如果有包含，请不要命名 url，要这样做，请转到 url 并添加:

app_name='products' 
urlpatterns = [ 
    url(r'^$', your_view.path, name='home'), 
 
] 

并将其引用到:

{% url 'products:home' %}
