You are not using correct syntax.您没有使用正确的语法。
<a href="{% url '<app_name>:<view_name>' %}"></a>
Where <view_name> is the view name you gave in urls.py for the app in which template is made.其中 <view_name> 是您在 urls.py 中为制作模板的应用程序提供的视图名称。 like here:像这儿：
from django.urls import path, re_path
from home import views
app_name = "home"
urlpatterns = [
path('', views.home_view, name='productsPage'),
re_path('^wishlist/', views.wishlist_view, name='wishlistPage'),
]
The name of the view is wishlistPage and app is home so you write to make a link to that page redirect:视图的名称是wishlistPage并且 app 是home所以你写了一个链接到那个页面重定向：
<a href="{% url 'home:wishlistPage' %}"></a>
Update更新
sub1 is the path of your MAIN VIEW FOR THAT APP when you want to visit <youwebsite>/sub1 . sub1是您想要访问<youwebsite>/sub1时该应用程序的主视图的路径。 In that case the urls.py for this app is incorrect.在这种情况下，此应用程序的 urls.py 不正确。 Edit this urls.py to be like this:编辑这个urls.py是这样的：
from django.urls import path, re_path
from Applications.Datos import views
app_name = "Datos"
urlpatterns = [
re_path('', views.Datos, name='sub1'), # UPDATE: LET IT BE BLANK
path('search/', views.buscar),
]
And update your main urls.py to b like this:并将您的主要urls.py更新为 b ，如下所示：
urlpatterns = [
[...your other urls...],
re_path(r'^sub1/', include(('Datos.urls', 'Datos'), namespace='Datos')),
]

It won't work like this.它不会像这样工作。 You have to call it like this.你必须这样称呼它。 in Django while linking html files/pages we use a slightly different approach.在 Django 链接 html 文件/页面时，我们使用稍微不同的方法。
<a class="nav-link" href="{% url 'sub1' %}">SubMenu</a>
